42. SiLVANUS CONGENER, Sp. 11. (A.M.) 



Elongate, narrow and parallel, dark reddish brown, rather 

 closely pubescent; prothorax much longer than broad, with an 

 indistinct longitudinal impression on each side of the middle, the 

 sides armed witli six moderately prominent teeth ; elytra finely 

 striate-punctate. 



Head with the sides nearly straight, deeply and closely punc- 

 tured at the base, somewhat less closely punctured in front. 

 Prothoi-ax elongated, slightly narrowed behind, rather strongly 

 and closely punctured, the disc somewhat flattened, with an indis- 

 tinct longitudinal impression on each side of the middle extending 

 from just behind the anterior margin to near the base ; the sides 

 nearly parallel and armed with six rather prominent teeth situated 

 at nearly equal distances from each other. Elytra rather long, 

 generally a little paler than the head and prothorax, finely striate- 

 punctate, the alternate interstices being almost impei'ceptibly 

 raised ; the sides arcuately narrowed behind. Legs reddish 

 ferruginous. Length 3-3J mm. 



South Australia. 



The somewhat larger size and narrower form of this species, in 

 conjunction with the more parallel sides, and less rounded angles, 

 of its prothorax, will serve to separate it from S. surinamensis. 

 The grooves on the prothorax in .S'. congener are indistinct and 

 comparatively broad.
