320 Mr. P. P. Pascoe on new Genera 



appears to have been made from the latter sex — and not from 

 a female, as stated. 



Taphroderes ohtusus. 



T. robustior, nitide piceus, Isevigatus, capite quam prothorace 

 multo angustiore, obsolete punctidato ; rostro paulo arcuato ; 

 antennis piceis, articulis tertio usque decimum unilateraliter pro- 

 ductis ; prothorace elongate, pone medium ampliato, antieo supra 

 linea longitudinali impressa notato ; elytris brevioribus, apice ob- 

 tusis, maculis quatuor ferrugineia (2 ante, 2 pone medium) 

 ornatis ; corpore infra piceo-nigro ; coxis anticis fulvis. Long. 

 4 lin. 



Hab. Amazons. 



At least twice as stout as the preceding, the apices of the 

 elytra not produced, &c. 



In reference to M. Lacordaire's note (Gen. vii. p. 410), I 

 have reexamined my Cyphagogus advena ; and although its 

 shorter rostrum approaches it to Zemioses, as I have already 

 remarked, in other respects (^'. e. antennas, legs, &c.) it is a 

 true Gyijhagogus. Aprostoma^ Guer., which Lacordaire had 

 not seen, but refers to the Taphroderinge, is a Colydiid, after- 

 wards named by Erichson Mecedanum. 



lonthocerus ophthalmicus. PI. XV. fig. 4. 



/. omnino nitide rufo-ferrugineus, apicibus articulorum antennarum 

 nigris exceptis ; rostro modice crasso, basi subcylindrico, antennis 

 in medio insertis ; prothorace la)vi, dorso anticc tenuiter, postice 

 fortiter sulcato ; elytris simpliciter striatis, striis tribus sutura- 

 libiis tantum conspicuis, apicibus extus planato-productis ; tarsis 

 parce pilosis. Long. 3 lin. 



Hab. Queensland (Rockhampton). 



Lacordaire founded lonthocerus on a species from Ceylon, 

 from which the present differs in its imiform colour, thinner 

 rostrum, and glossy elytra otherwise sculptured. My speci- 

 men, like Lacordaire's, appears to be a male. With Ephebo- 

 cerus^ Lac, it forms a subfamily remarkable for the long- 

 slender antennge clothed with delicate hairs, and large eyes 

 occupying the greater part of the head. 



Trachelizus Howittii. 



T. nitide fulvo-testaceus ; capite prothoraceque Isevigatis, remote 

 punctatis ; rostro paulo arcuato, hand gibboso, inter antennas 

 sulco longitudinali impresso ; oculis parvulis ; antennis articulo 

 prime vix incrassato, ultimo acuminate ; sxdco prothoracis ab apice 

 ad basin extenso ; elytris fortiter striatis, sutura valde elevata ; 

 corpore infra sparse punctulato ; metasterno segmentisque duobus
