2 ADYERTISEMENT. The donation made to the University of Oxford by the late Rev. F. W. Hope, of his entire Collections and Library of Natui-al History, and the subsequent acquisition of the Burchell, Wells, and other Collections, including also my own, have enriched the University Museum with a large number of new and rare species of Insects, from which it has been considered advisable that a selection should be made for illustration in a manner worthy both of the donor and the University. In making this selection I have considered that it would be most beneficial to illustrate certain Groups or Families rather than isolated Species. With this view the Groups of Goliathidse and Cremastocheilidaa have been selected a complete Monograph of the latter being given, with figures of upwards of one hundred Species. Of the singular Family Paussidse upwards of fifty Species are figured for the first time, together with many other curious Coleoptei-a. Many remarkable Groups and Species belonging to the Orders Hymenoptera, Orthoptera, Neuroptera, Hemiptera, and Lepidoptera, as well as several singular Apterous Groups, are also given. The Plates are engraved and coloured from drawings and dissections prepared by myself. I have considered it due to the memory of Mr. Hope to reprint the late Dr. Petti- GEBw's Biographical Notice of him, together with a concise account of the Collections presented by him to the University of Oxford, and a list of his published Works and Memoirs.

3 CLASS AEACHNIDA. ORDER-ADELARTHEOSOMATA. Westw. Family CYPHOPHTHALMIDvE. This family, hitherto composed of a single genus, Cyphophthalmus, founded upon a single species, C. diiricornis, inhabiting the caves of Carniola, was proposed by Herr Joseph in the Berlin Entomologische Zeitung, vol. xii, p. 241 and p. 269, pi. i. It is nearly allied to Phalangium. A second species of the group was forwarded to me by Herr Snellen van Vollenhoven, from the Royal Museum of Leyden, as a native of Sumatra, and as a species of Trogulus. As it differs in several respects from the type of the family, I have formed it into the Genus STYLOCELLUS. (Plate XXXVII, Figs. 7, 7 a, corpus infra visum ; fig. 7 b, idem e latere.) Cephalothorax dorso integro, absque impressione semicirculari dorsali ; lateribus in cornua duo brevia porrecta, apice ocelligero ; chelicers palpis breviores, articulo basali dimidium articuli cheliferi longitudine jequanti chelffi simplices nee serratse : spiraeula ad basin abdominis rotundata neo lunata ; pedes 8, fere sequales, tibiis biarticulatis, tarsis biarticulatis, articulo basah brevi, secundo multo longiori crassiori subtus fisso, ungue unico terminali instructo (fig. 7 c) ; pedes antici modice elongati absque spina ad angulum internum articuli basalis abdomen ovale convexum e segmentis septem coalitis, formatum.

Habitat ; Sumatra. In Mus. Reg. Lugdun. et in Mus. Hopeiano Oxonise. I have seen a closely-allied species of a ferruginous colour from Java in the collection of the British Museum. ' Forty years ago I proposed this term for those Trachearian Arachnida which have the 'abdomen annulated, although occasionally in an indistinct manner,' the other orders of Arachnida being named by Dr. Leach 1. Dimerosoraata (spiders) ; 2. PoIjTnerosomata (scorpions) ; 3. Monomerosomata (mites) ; and 4. Podosomata (Pyconogonum and Nymphon). The term Ai-throgastra has recently been applied to my Adelarthrosomata, to which, notwithstanding their different mode of respiration, the scorpions have been unsatisfactorily added.

4 Family TROGULID.E. 201 Family CRYPTOSTEMMIDiE. The Genus Cryptostemma of Guerin-Meneville is formed of a single species received by M. Guerin from the late Herr Westermann as a native of Guinea. It is nearly allied to Phalangium and Trogulus, but the eyes are wanting and the chelicera; are porrected and pediform ; the cephalothorax is square, with the anterior margin porrected in form of a clypeus ; the abdomen is as wide as the cephalothorax, and twice its length, being oblong, with the posterior angles rounded. The legs are very unequal in length, the second pair being the longest, with 4- or 5-jointed tarsi (Guerin-Men. Rev. Zool. 1838, p. 11; Diet. Pittor. d'hist. Nat. pi. DXXXIX, fig. 7; Walckenaer, Apt. iii. p. 131, pi. XLVII (not XXXIX), fig. 4). An allied form was captured by Mr. H. W. Bates in his Amazon researches, which constitutes a distinct genus, which I have named Gends CRYPTOCELLUS.

It is with great pleasure that I am here enabled to introduce this interesting Genus into the British Fauna, a new species having been captured in Dorsetshire by the Rev. Pickard Cambridge, who has kindly placed it in the Hopeian Collection, and allowed me to describe and figure it in this work. The Genus is composed, for the most part, of European species, the type_being the Phalangium tricarinatum 2 D
