The downward-directed appendage of the sides of the prothorax 

 is no doubt characteristic of the male. This insect seems to be a 

 genuine Silis, the only abnormal character I notice consisting in 

 the head being somewhat strongly and narrowly produced in front 

 of the antennae.

Niger, prothorace elytrorum fascia lata mediana (hac ad suturam 

 et ad margines late rales dilatata) abdomineque (hujus seg- 

 mento apicali et segmentorum ceterum maculis lateralibus 

 exceptis) rufo-testaceis; pilis erectis elongatis vestitus; capite 

 prothoraceque vix perspicue punctulatis ; hoc quam longiori 

 dimidio latiori, latitucline majori ante medium posita, lateri- 

 bus valde rotunclatis; elytris in parte rufotestacea crebre 

 fortiter rugulose, in parte nigra antica sat fortiter sat rugo- 

 lose, in parte nigra postica parum perspicue, punctulatis. 

 Maris antennarum articulo 1° brunneo-testaceo apice extus 

 fortiter dilatato, 2° supra brunneo-testaceo quadratim valde 

 dilatato supra concavo subtus convexo, femoribus anticis 

 supra in medio valde triangulariter excisis.

The width of the elytral fascia on the suture arid on the lateral 



margins is not much less than half the length of the elytra ; 



between the suture and lateral margin on either side the fascia 



is strongly and arcuately emarginate both in front and behind. 



This species is near L. (Apalochrus) cinctus, Redtb., but with 

 the dark part of the elytra scarcely cyaneous. It differs from L. 

 cinctus (if I have identified it correctly) also by the shape of the 

 prothorax, which is at its widest very near the front and from 

 that point is narrowed arcuately but very strongly hindward. I 

 have not seen a male of the species that I take to be L. cinctus.
