54 APPENDIX. 



less closely, punctured, but with the minute intermediate punctules 

 more distinct ; in their elytra being' relatively longer, and a trifle 

 more rounded-off at the shoulders ; and in their limbs being appre- 

 ciably more developed with the legs more pilose, the third tarsal 

 joint perceptibly broader, and the front tibiae of the male sex a little 

 more scooped out internally.

Lichenophagus buccatrix, n. sp. 



L. squamulis minutissimis, vel brunneis vel cinereo-fuscis, densis- 

 sime tectus, sed setulis fere carens (sc. brevissimis, interdum aegre 

 observandis), subter squamulis opacus ; rostro leviter concavo sed 

 argute canaliculate, subtus appendiculis late divaricatis exstanti- 

 bus instructo, oculis demissis; prothorace brevi, ad latera valde 

 rotundato, parce punctato, utrinque necnon in medio plus minus 

 obscure (interdum obsolete) subcinereo-lineato ; elytris convexis, 

 inflatis, ovato-ellipticis, ad latera valde et sequaliter rotundatis 

 (antice paulatim valde angustioribus), punctato-striatis, inter- 

 stitiis alternis plus minus evidenter tessellatis ; an tennis elongatis, 

 gracilibus tarsisque piceo-testaceis ; pedibus robustis. Long, 

 corp. lin. 3-3|. 



Mas prothorace simplici, pedibus paulo robustioribus, tibiis ad 

 apicem internum magis incurvis. 



Fcem. prothorace ad basin in medio carinula obtusissima (vix ele- 

 vata) valde abbreviata instructo ; pedibus subgracilioribus, tibiis 

 rectioribus.

This is by far the most extraordinary member of the present genus 

 which has been detected, its gigantic size (as compared with all 

 except the L. incomptus, which may possibly be the exponent of a 

 distinct genus), elliptical inflated elytra (which are greatly rounded 

 in the middle, and much narrowed before and behind), in conjunc- 

 tion with its slender antennae (for a Liclienophagus) and the greatly 

 developed divaricating processes on the underside of its rostrum at 

 the apex, giving it a character completely its own. Its sexual dis- 

 similarities, also, are more pronounced than in any of the other 

 species, its males having their legs thicker, and the tibia? more 

 incurved at the apex, than is the case with the females ; whilst the 

 latter have a greatly abbreviated, very obtuse, and suddenly termi-
