34 NORTHERN ZOOLOGY 



XVI. * Genus STEREOCERUS. 



Labrum transverse, scarcely emarginate. 



Palpi, maxillary with the second joint subcylindrical, the third obconical, in the male as long as the 

 last, in the female longer, the last subcylindrical truncated at the apex. 



labial with the last joint subcylindrical truncated at the apex. 



Labium emarginate with a short entire tooth in the notch. 



Antennae robust, with the third joint a little longer than the rest, suddenly incrassated at the sum- 

 mit ; the fourth clavate ; the following ones compressed and subcampanulate ; the last ovate. 2 



Body rather narrow. Head somewhat orbicular ; frontal impressions oblique : prothorax nearly 

 as long as wide, rather narrowest at the base, truncated before and behind ; dorsal channel not ab- 

 breviated ; lateral margin reflexed, depressed posteriorly ; basilar impressions with a double furrow, 

 anterior angles rounded, posterior rather acute : scutellum acutarigular : elytra parallel, subsinuated 

 at the apex : hand of the male with the three first joints dilated and triangular. 



This genus, or subgenus, appears to connect those that have robust antennas, as Omaseus, &c. 

 with those that have those organs more slender, as Pcecilus, &c. Its general aspect is that of Cur- 

 tonotus, but the intermediate tooth of the labium (Mentum Latr.) is entire as in Bradytus : the 

 penultimate joint of the palpi in the male is as long as the last, which in the first of these genera is 

 longer and in the second shorter ; the last joint is more cylindrical and consequently more widely 

 truncated at the summit than in either. 



(43) 1. * Stereocerus similis. Similar Stereocer us. 



S. ( similis J piceo-niger, nitidus ; anteimis pedibusque castaneis ; elytris ccneo-piceis ; occipite punctulato. 

 Similar Stereocerus, piceous-black, glossy ; antenna? and legs chestnut ; elytra piceous tinted with bronze ; occiput 

 minutely punctured.

DESCRIPTION. 



Body of a piceous-black, glossy. Palpi piceous ; antennas chestnut : frontal impressions deep, 

 rather curving ; occiput punctured with scattered punctures : prothorax nearly* square with curved 

 sides ; basilar impressions wide, punctured, deeply bisulcate, with an elevated little ridge between 

 them and the margin : elytra bronzed, furrowed, furrows scarcely punctured : legs pale chestnut. 



In the female the elytra are not bronzed, the legs are darker, and the terminal joint of the palpi 

 is longer.
