appears to be a female and lias the front tarsi scarcely 

 dilated ; it comes extremely close to the L. pagana, but 

 ditfers in havin<^ the head slightly shorter and the hind 

 body a little more closely punctured as Avell as in its dark 

 marking^s. The tuberculate mentum readily distinguishes 

 it from L. polita and L. cjermana. 



Stilicus. 



The species of this genus found by Mr. Bates are only 

 two in number, and are evidently closely allied to the two 

 species S.jugdlis and -S". carinatus described by Erichson 

 from Columbia. 1 have also three or four other closely 

 allied species from Brazil, so that the genus is probably 

 quite as well represented in South America as in any 

 other part of the Avorld ; the species, though widely distri- 

 buted on the globe, being nowhere numerous. 



1. Stilicus amazonicus, n. sp. Niger, an tennis pedi- 

 busque testaceis, capite thoraceque opacis, hoc fortiter 

 carinato ; elytris nigro-reneis, apice testaceo, minus fortiter 

 punctatis. Long. corp. 2| lin. 



Antennai rather long, qtiite yellow ; 3rd joint scarcely 

 longer than 2nd ; 10th joint quite as long as broad ; lltli 

 joint rather long, nearly as long as the two preceding to- 

 gether. Palpi yellow, slightly infuscate. Labrum large. 

 Head dull blackish, rather elongate, very densely punc- 

 tured; the punctures on a small space on the middle 

 coarser than elsewhere, so that this spot is a little shining, 

 but none of the pinictures are wanting, neither are the 

 interstices there any broader. Thorax just ^ lin. in length, 

 strongly angulated at the sides and abruptly narrowed 

 towards the front, densely punctured anjd with a shining 

 conspicuous smooth line along the middle. Elytra just 

 as long as the thorax and about as broad as long, a little 

 shining, of an obscure brassy colour, with the extremity 

 pale yellow ; rather sparingly and not coarsely though dis- 

 tinctly punctured. Hind body densely and finely punc- 

 tm-ed, slightly shining. Legs clear yellow. 



Ega ; a single female specimen. 



This species is rather larger than the European S. 

 orhiculatus ; its antenna? are longer, the terminal joint or 

 the maxillary palpi is more elongate and more linear, the 

 head behind the eyes is longer and less truncate, the
