J\Ir. F. P. Pascoc on new Species of Rhynchitcs. 391 



XLVIII. — Descriptions of some new Asiatic Species of 

 llhynchltes. By Francis P. Pascoe, F.L.8. &c. 



It is chiefly from the collection made by ]\Ir. Wullacc that I 

 have selected the tullowiiiu,- well-marked sj)ecies of" /I'/'/yz/rA/^^'.*;. 

 The <4-eiius was separated tVoiu Atteldhxs, Linn., by Ilerbst in 

 ]7y7, and com])rises about 100 species, including th<wc here 

 described ; it is almost cosmopolitan, but has not yet been 

 found in Australia. ]M. Koelofs has lately described several 

 new species from Japan ; and I have here added another 

 (allied to R. hetuleti) which is also found there (Yokohama), 

 although it does not seem to have been met with by Mr. 

 Lewis's collectors. 



Blnjnchites elysius. 



R. loetc cserulcus, sparse albido-pilosus ; rostro ( $ ) corporis dimidia 

 longitudinc, niodice arcuate, vage punctidato, dimidio basali tri- 

 carinulato ; ( J ) breviore et manifeste crassiore, infra aiiguUs ex- 

 terioribus utrinque fortitcr quinquedentatis ; autennis baud elon- 

 gatis, articulis 3'^, 4° a;quaUbus ; clava magna, grisea, art. duobus 

 basalibus triangularibus, singulis latitudine haud longioribus, ^A- 

 limo ovato, acuminato ; prothorace latitudine baud loiigiore, sat 

 vage punctulato ; elylris anipHs, striato-punctatis, puuctis ap- 

 proximatis, iutcrstitiis sat cout'crtim puiictulati« ; tibiis costulatis. 

 Long. 4 lin. 



Hah. Sumatra. 



Allied to two species known as R. pJn'lippensis, Chev., and 

 R. ca'Iestiniis^, Gyll., but at once distinguished from both by 

 the sparse punctuation on the prothorax. R. azureus, 01. f, is a 

 very distinct species, hitherto overlooked, except that it is 

 doubtfully cited as a synonym by Gyllenhal for his coelestinus. 



Rhynchites alcyoneus. 



ii. ca^ruleus, elytris violaceis, albido-pilosus ; rostro tenui, corporis 

 longitudinc vix dimidia, modice arcuato, haud carinulato, basi inter 

 ocxdos compresso ; anteiniis haud elongatis, articulo tertio quam 

 quarto paulo longioro, clava concolori, art. duobus basalibus elon- 

 gato-triaiignlaribui>, ultimo anguste ovato, acuminato ; prothorace 



* There is some confusion in the sjTionjTiiy here. Taking Lacordaire's 

 note (^Gen. vi. p. 555 ) as con-ect, the following would be the chronologj- : — 

 Rhynchites calediniis, Ci} 11., 1833. 



(jrandis, Imlioir, 1^*38. 



phi/ij)pcnsis, Chev., 1S41. 



Yet Laoordairo, adopting the two latter names, gives the first us a syn- 

 onym for both.

 and Sumatra.
