22 Mr. J. O. Westwood's Description of a new 



V. Description of a new Species of the Coleopterous Family 

 Paussidse, from India. By J. O. Westwood, F.L.S., 

 Sec. Ent. Soc, &c. 



[Read 4th August, 1845.] 



Since the publication of the last number of my " Arcana En- 

 tomologica," in which I completed an illustrated monograph of 

 the family Panssidce, 1 have been favoured by two gentlemen 

 in India with specimens of two species of this family, forwarded 

 to me through the medium of post letters, inclosed in small quills. 

 One of these insects is the Ceratoderus hifasciatus, being the third 

 individual of that species sent to Europe, the first having been 

 brought from India by Fichtel, and deposited in the Royal Cabinet 

 at Vienna, and the second being in the Collection of the Rev. F. W. 

 Hope. This third specimen was sent me by Lieut. Col. J. B. 

 Hearsey, having been taken on the clothes of one of his soldiers 

 whilst on duty. The other insect, received by post, of which I 

 now beg leave to lay a description and figure before the Society, 

 was sent rae by W, H. Benson, Esq., having been captured by 

 that gentleman. 



From the apparently 5-partite, depressed clava of the antennae, 

 the general structure of the maxillary and labial palpi (the former 

 with the terminal joint smaller and more slender than the pre- 

 ceding, and the latter with the terminal joint large, subovate and 

 subtruncate at the extremity), the tibiae destitute of calcaria, and 

 the long tarsi with the first joint larger than either of the three 

 following joints, this new species enters into the genus Ceratoderus, 

 which I proposed for the reception of Paussus bifasciatas ; but in 

 addition to a very different general facies, destitute of the glossy 

 surface so peculiar in that species, with comparatively shorter and 

 broader antennas and feet, this new insect differs from it in the 

 dilated second joint of the maxillary palpi, which is almost rounded 

 and flattened, in the bipartite and angulated structure of the pro- 

 thorax, the setigerous-margined elytra, and the outer angle of 

 the extremity of the tibias being obliquely rounded off. 



The genus Ceratoderus* must therefore be more restrictedly 



* It may be as well to observe in this place, that as this generic name is derived 

 from xEj, cor, and not from xsja, cornu, it is strictly applicable only to the C. bi- 

 fasciatus. It would therefore perhaps be better to propose a distinct generic name 

 for the group, and to give each of the sections a separate subgeneric one ; the name 

 of Melasnospilus may therefore be proposed for the genus, Ceratoderus be retained 

 for C.bifasciatus, and the name of Meriimoderus be given to C. Ben$oni.
