Htpermetra. 

 (A.terpinae.) 



Dexagice omnino congruit, practer scrobes infra rostrum haud 

 conniveutcs ; et tibice apice latiores, uncis carentes. Corpus 

 cylindricum. 



The only exponent of this genus is a peculiar insect, very dif- 

 ferent in appearance to the last, though the generic characters 

 are almost the same. The scales on the upper part, except at 

 the apex of the elytra, are so exactly like the derm they cover as 

 to be easily overlooked. 



Hypermetra analis. (PI. IX. fig. 5.) H. elongata, brunnea, 

 supra squamis concoloribus, apice elytrorum excepto, tecta; capite 

 rostroque sat nude pallido-squamosis, hoc dimidio apicali paulo ex- 

 cavato ; antennis piceis ; funiculo articulis quinque ultimis rotun- 

 datis, extrorsum sensim crassioribus ; prothorace latitudine fere ses- 

 quilongiore, disperse punctata, punctis leviter impressis, unisquami- 

 geris ; scutello distincto, orbiculari ; ely tris latitudine plus triplo 

 longioribus, striato-punctatis, punctis elongatis, vix approximatis, 

 unisquamigeris, interstitiis modice convexis, apice sat subito declivi- 

 bus, dense albido-squamosis, et singulatim tuberculo magno instruc- 

 tis 5 corpore infra pedibusque subpiceis, squamis albidis vix dense 

 tectis. Long. 2^ lin. (rost. inch).
