amplis. Processus intercoxalis truncatus. Corpus squamosum, 

 setosum. 



The absence of ocular lobes and the greater length of the 

 scape are the principal characters differentiating this genus 

 from Perperus. The elytra, also, are not vertically declivous 

 behind ; and the eyes are round or nearly so and away from 

 the prothorax, not contiguous to, or, in some cases, partly 

 covered by the ocular lobes. The corbels of the posterior tibiae, 

 so far as I can make out from gummed specimens, are pre- 

 cisely as in Perperus. 



Ocynoma antennata. 



0. fusco-castanea, squamis griseis fuscisque, setulis longis inter- 

 jeetis, subtus sparse argenteo-squamosa ; capite rostroque griseo- 

 squamosis, hoc in medio carinulato, apice vage setuloso ; antennis 

 ferrugineis, parcius niveo-pilosis ; funiculo articulo basali longiore 

 caeteris gradatim brevioribus ; prothorace vittis tribus fuscis valde 

 indeterminatis notato ; elytris anguste cordatis, seriatim punctatis; 

 dorso utrinque vitta determinata fusca notatis ; pedibus ferrugi- 

 neis, tibiis tarsisque pallidioribus. Long, lf-2 lin.

Ocynoma cordipennis. 



0. fusca, squamis silaceis, setulis breviusculis interjectis, subtus 

 sejunctim albido-squamosa ; rostro longiore, minus tenuato, haud 

 carinulato ; antennis minus elongatis ; prothorace longitudine vix 

 latiore, vage nigro-punctato ; elytris cordatis, tenuiter slriatis, 

 singulis linea pallida, in medio interrupta, indeterminata, notatis ; 

 pedibus squamosis, tibiis tarsisque ferrugineis. Long. 2 lin.

Decienus. 



Rostrum modice robustum, breviusculum ; scrobes flexuosae, postice 

 leviter iiupressae, oculos attingentes. Oculi rotundati. Scapus 

 medium oculi vix superans ; funiculus articulis quinque ultimis 

 breviter obconicis, subsequalibus. Prothorax lobis ocularibus ob- 

 soletis. Elytra subcordata, postice leviter declivia. Pedes antici 

 majusculi, elongati ; tibim anticae apice calcaratae, posticse corbellis 

 apertis. Caeteris ut in Perpero. 



From its appearance I had originally placed the species 

 described below with Prosayleus ; but an examination of the 

 mouth shows that it is phanerognathous, and is in many 

 respects similar to Perperus^ although from its open posterior 

 corbels it is probable that Lacordaire would have found 

 another place for it. It is a dark, somewhat spider-like looking 

 insect, with a few indistinct greyish stripes ; in the female,
