The description given above will show that in some respects 

 this genus resembles Parroa of Castelnau. The very elongate 

 form, slight legs, and largely produced sternum gives it, however, 

 a very different aspect. 



BErTHTSTERNUM CALCARATUM. 



Long. 12 lin., lat. 3 lin. 



Nigrum nitidum liBve, capite subconvexo inter ocalos leviter 

 bi-impresso, clypeo utriuque profunde bipunctato, thoi-ace 

 longo antice truncate capite latiori angulis rotundato- 

 productis, medio canaliculato, postice truncato subangustato 

 trans versim impresso lateribus marginatis vix rotundatis, 

 elytris hand thorace latioribus punctis paucis margin- 

 alibus, tibiis anticis arcuatis prope apicem emarginatis dente 

 interno apicali magno, femoribus intermediis calcare magno 

 subtus versus apicem armatis, prosterno lato piano retrorsum 

 porrecto subrecurvo. 

 The antennae palpi and tarsi are piceous, the rest of the insect 

 is black, nitid, and smooth. The head is a little convex, has two 

 large shallow fovege between the eyes, and two small but deep 

 punctures on each side of the clypeus. The labrum is canaliculate 

 in the middle, and has its anterior edge marked with strong 

 setigerous punctures. The mandibles are lightly striolate longitu- 

 dinally, and the right one is furnished with a tooth in the middle. 

 The eyes are round and rather prominent, and there is a small deep 

 puncture behind and a little above each eye. The antennoe are 

 much shorter than the head and thorax united, the first joint is 

 thick, the remainder are all obconical, the second joint being the 

 smallest, and the third a little the largest, and gradually tapering 

 to the apical joint which is acuminate. The thorax is slightly 

 broader than the head in front, nearly twice as long as wide, 

 truncate in front and behind, margined at the sides, obtusely 

 produced at the anterior angles, very slightly rounded on the 

 sides, very little narrowed towards the base, transversely im- 

 pressed near the base and finely canaliculate on the median line. 

 The elytra are elongate, not wider than the thorax, and smooth 

 with the exception of three or four punctures in the humeral
