190 MIOLISPA FAUSTI. 



Prothorax nearly as long as rostrum and head together, 

 ovate , regularly curved at the sides , the apical margin is 

 much narrower than the base ; above it is furrowed , ru- 

 goso-punctate, the punctures are scaled. 



Elytra elongate, with the base emarginate, the sides in 

 the basal third are of the same width as the prothorax, 

 thence regularly narrower, the apex is emarginate in the 

 middle ; above they are punctured and furrowed , the punc- 

 tures regular , the interstices raised , narrow, the 1st furrow 

 impunctate. 



Legs regular, brown. Body beneath brown, shining, 

 sometimes the prosternum and metasternum brown-red ; the 

 head , basal portion of the rostrum , coxae and apical seg- 

 ment of the abdomen are scaled ; the metasternum is 

 shortly channelled , depressed and punctured at the sides , 

 the punctures with short hairs; the abdomen has a feeble 

 impression and rare punctures at the base. 



The female differs by the body being more robust , the 

 head being shorter and broader , the rostrum at the base 

 shorter and thicker, the apical portion longer , cylindrical , 

 briefly furrowed at the base; the antennae are more robust, 

 with the joints shorter, the median ones transverse; the 

 prothorax narrower anteriorly, the elytra more parallel at 

 the sides, the l^t furrow broader. The colour is also brighter, 

 more reddish in the specimens examined , the median por- 

 tion intensely black. 



This species belongs to the group of M. exarata Desbr. 

 but differs by the head and the antennae being a little 

 broader, the prothorax ovate, regularly curved and more 

 enlarged at the sides ; it also differs in colour, and the band 

 of whitish scales at the sides is wanting.
