Monohammus ocellatus, n. sp. 



Fuscus, cervino-pubescens ; capite impunctato, lobis oculorum infe- 

 rioribus magnis ; prothorace dorso impunctato, leviter insequali ; 

 elj'tris foveis sparsis ocellatis, apicibus oblique vel sinuato 

 truncatis ; antennis fuscis, ( c? ) corpore plus quam duplo lon- 

 gioribus, ( $ ) corpore sesqui-longioribua. 



Long. 17-25 mm., lat. 5-8 mm, 



Hab. N. India and Penang. 



Dark brown, with a dark grey or fawn-coloured pubescence. 

 The head impunctate, pubescent. The lower lobes of the eyes 

 large. The prothorax somewhat uneven above, closely 

 pubescent, with a few minute granules on each side of the 

 disk behind the middle ; the transverse grooves, two anterior 

 and two posterior, not very distinct. Elytra with scattered, 

 broad, shining, ocellate punctures, which are smaller, closer, 

 and somewhat asperate towards the base ; the apices obliquely 

 and more or less sinuately truncate, with the outer angles in 

 some specimens very feebly produced. Antennse in the male 

 dai-k brown, nearly three times as long as the body, with the 

 scape greyish and somewhat rugulose along its outer border; 

 in the female dark brown, about half as long again as the 

 body, and with the scape greyish and smootli ; the " cica- 

 trix" with a complete rim. The legs and underside of the 

 body pubescent like the upper. The middle tibite without a 

 notch or groove. The intercoxal process of the mesosternum 

 with a feeble tubercle in front. 



Synonymical Remarks. 



The genus Cacoscapus of Thomson (' Revue et Magasin de 

 Zoologie,' 1878, p. 47) is evidently, from its description, iden- 

 tical with the genus Stratioceros of Lacordaire, which stands 

 first among the Monohammides in that author's great work, 

 the ' Genera des Col^opt^res,' Thomson's type species, 

 Mouhotii, is also, as far so I can judge from his description, 

 synonymous with the princeps of Lacordaire. The same 

 locality is given for each. M. Thomson's blunder is the less 

 excusable since the genus is not only well-marked, but the 

 species is, as Lacordaire justly said, one of the finest in the 

 group. 



in the same paper Thomson describes, under the name of 

 Leprodera arista^ a species which was previously described by 

 Pascoe as Leprodera verrucosa. 



Monohammus Fredericus, White, agrees in every respect 

 with the description of Thomson's Monohammus deperatus \ the
