MR. F. P. PASCOE ON THE CUECULIONID^. 



turn primum abdominis protensa, apice aperta. Metasternum 

 modice elongatum. Abdomen segmentis intermediis sequalibus. 

 There is only one other genus in the subfamily in which the 

 pectoral canal passes beyond the metasternum — Fanolcus ; and in 

 that it extends to the extremity of the abdomen. The only spe- 

 cies of this genus is an insect of a dark chocolate- colour, the scales, 

 from their position, having a cloth-like texture, with the sides of 

 the prothorax and elytra ochreous grey ; on the former the grey 

 begins at the apex, leaving a well-limited dark triangular patch on 

 the centre and base. The genus may be placed after Mecistocerus.

(Cry ptorhy nchinse. ) 



Hostrum validum, subarcuatum ; scrobes medians?, laterales. Fu- 

 niculus breviusculus, articulis duobus basalibus longioribus, 

 ultimo latiore ; clava elongata, subadnata. Oculi tenuiter gra- 

 nulati. Prothorax transversus, antice angustus, apice productus, 

 lobis ocularibus prominulis. Elytra prothorace vix latiora, 

 hurneris callosa. Femora tibiteque cornpressae, ilia longiuscula, 

 valida, infra dente instructa ; ha3 breves, basi extus angulatee ; 

 tarsi normales ; unguiculi divergentes. Mesosternum valde 

 elevatum, fornicatum. 



It is very probable that Cryptorliynclius albicollis, Grerm., be- 

 longs to this genus. Unfortunately CryptorhyncJius has become 

 one of those thoroughly vague generic names that carries with it 

 no idea of definite characters ; but the colouring, which is remark- 

 able, is very similar to that of the species described below. This 

 genus belongs to the Chcetectetorus form, and is allied to Meta- 

 cymia, which has a small claw-joint, a longer metasternum, and a 

 broad intercoxal process. Chimades, another ally, has, inter alia, 

 straight, terete tibiae.
