74 OXVCEPHALA. 



in the Icotwyraphie da Regne Anim. pi. 48. fig. 1), to Oxi/cephala 

 depressa, the insect from Avliich I have drawn the above generic 

 characters, that I have no hesitation in adopting his name. He 

 subsequently removed his species to Cryptonyclms, an African genus, 

 differing entirely in the structure of its mouth from the present. 



1. Oxycephala speciosa (Boisd.). B.M. 



Botiyonopa speciosa, Blanch., TjC Urville's Voyage au Pole Sitd, Zool. 

 t. iv. p. 311. pi. 18. fig. 5. 



0. elongata, subconvexa, aurantiaca ; capite, prothoracis macula 

 anticii, pedibus (femoribus basi cxceptis) nigris ; elj'tris costulatis, 

 fascia lata antica apiceque nifo-cyaneis. 



Var. A. Fronte pimcto flavo; elytris macula ovata subbasali punctoque 



latcrali, ea parallelo, apiceque c^-aneis. 

 Long. 6 Hn. 



Hispa speciosa, Boisd. Voy. de r Astrolabe, t. ii. p. 535. 

 Callistola speciosa, Guer. Rev. Zool. p. 333. 



Hah. Macassar ; collected by Mr. Wallace. Waigieou (Boisduv(d). 

 British Museum, and collections of W. W. Saunders, Esq., E. 

 Sheppard, Esq., and J. S. Baly. 



This species is the type of Dejean's genus Callistola. The de- 

 scriptions of Boisduval and Guerin — both drawTi, I believe, from the 

 specimen in Count Dejean's collection — differ sHghtly from that given 

 by Blanchard in the Voyage au Pole Sud. AU the individuals I 

 have seen agree with the insect described, by the latter author, and 

 it is on his authority that I have united the two forms. Boisduval 

 omits any notice of the small lateral spots on the elytra mentioned 

 by Guerin. 



2. Oxycephala depressa, n. sp. Tab. VI. Fig. 4. 



0. elongata, depressa, paUide fidva ; antennis ocidisque nigris ; ely- 

 tris subcostatis, plaga magna subapicali, ramiilum suturalem brevem 

 sursum omittente, nigra ; thoracis angiilis anticis explanatis, an- 

 trorsum obli(]ue productis. 



Long. 4-5 liu. 



0. elongate, depressed, pale fidvous ; antennae, eyes, and a subapical 

 I)atch on the elytra, black. Head slightly raised and flattened on 

 the vertex, deeply punctured ; in the middle is a longitudinal 

 groove, which is carried forward along the upper surface of the 

 middle tooth. Thorax subquadi'ate ; sides straight and jiarallel, 

 anterior angles dilated into a flat process which is produced ob- 

 li(iuely forwards and outwards, its apex obtuse; anterior margin 

 thickened, convex ; above slightly convex, covered with large deej) 

 punctures, not crowded, and much more remote on the disc. 

 Scutellum pentangular, smooth, impunctatc. Elytra rather broader
