299. Lichenophagus acuminatus, tToU. (Tab. VIII. fig. 3.) 

 L. elongatus oblongo-ovatiis fusco-niger, squamis siibcinereo-brunneis densissime tectus et undique 

 setulis rigidis erectis dense obsitus, protborace punctate, elytris leviter punctato-striatis, sub- 

 parallelis ad apieem leviter acuminatis, interstitiis alternis vix tessellatis, antennis fusco-piceis, 

 tarsis ferrugineis. 

 Long. Corp. lin. 2. 



Habitat in insula Desertse Grandis, semel tantum (Maio exeunte a.d. 1850) repertus. 



L. rather slenderer than tbe L. fritillus, and less ovate, being more parallel and oblong ; also of an 

 obscurer and more rusty brown hue, being less variegated with paler and darker scales ; densely 

 beset all over with short, robust, and erect setae, which however are longer and more perceptible 

 on the elytra than on the prothorax. Rostrum and prothorax as in that species, except that they 

 are not quite so deeply punctured, and that the widest point of the latter is perhaps rather more 

 strictly medial. Elytra, likewise, rather less deeply punctate-striated; more parallel at their 

 base and less shortened behind, their apex being comparatively produced or acuminated ; .the 

 alternate interstices very much less tessellated than in that insect, being apparently almost con- 

 colorous with the rest of the surface. Antenna and leffs as in the L. fritillus ; except that the 

 latter are a little longer, and have their tarsi of an obscurer testaceous, or ferruginous. 



Hitherto unique, tlie example from which the above diagnosis has been com- 

 piled ha\-ing been discovered by myself on the Dezerta Grande, during my encamp- 

 ment on that island with the Ptev. E,. T. Lowe, at the end of May 1850. It is an 

 exceedingly distinct species, as may be gathered from the description. Like most 

 of the Cyclomides, its habits are noctui'nal, — my specimen having been captured 

 at night, attracted by the light of a candle, on the inner canvass of my tent.
