40 APPENDIX. 



in canaliculam pectoralem profundam (inter coxas anticas termi- 

 natam) arete applicando ; scrobe profunda, subrecta, ad latera 

 rostri posita, necnon ad basin ejus ipsam ducta atque ibidem 

 abrupte terminata: prothorace ovato-subconico : scutello vix (vel 

 potius hand) observando ; elytris subellipticis, connatis : alis nullis. 

 Antennae ante medium rostri inserts ; scapo subrecto, paulatim 

 clavato ; funiculo 7-art to , art l mo paulo longiore, vix latiore, reli- 

 quis parvis, inter se arete adpressis, longitudine subaequalibus, 

 latitudine vix crescentibus ; capitulo 4-annulato. Pedes robusti, 

 antici ad basin paululum, intermedii latins, et postici latissime 

 distantes : femoribus muticis : tibiis subrectis, extus praesertim 

 versus apicem sensim pilosis, ad apicem in uncum deflexum pro- 

 ductis : tarsis brevibus, angustis, pseudotetrameris, unguiculis 

 minutissimis. 



As my diagnosis of this extraordinary little genus was published 

 in the ' Ann. of Nat. Hist.,' I have thought it desirable to compile 

 one afresh for the sake of incorporating it into this Catalogue. The 

 two very closely allied species which compose it are certainly most 

 anomalous in structure, their total freedom from eyes, and the fact 

 of their bodies being impressed beneath with a very wide longitudinal 

 concavity (which extends through the metasternum and the first and 

 second abdominal segments), in conjunction with their short sub- 

 filiform feet and exceedingly minute claws, giving them a character 

 essentially their own. Their antennae are implanted between the 

 middle and apex of the rostrum, the latter of which is received into 

 a deep pectoral groove (terminating between the anterior coxa3) ; 

 and their surfaces (except under a high power of the microscope) 

 are free from setae and hairs, but are densely covered with large 

 and exceedingly depressed scale-like granules (or, more properly, 

 perhaps, granuliform scales). Their rostra are formed on nearly 

 the same type as that which obtains in Acalles, the members of 

 which genus will, I believe, be found, on the whole, to be their 

 nearest known allies.
