 strongly punctured; elytral striae deep, regular, with close, deep punctures; 

 interspaces finely rugose, thinly clothed with short, yellow hairs.

Length, 2-5 mm.; shaped like Hylurgops; nearly black; pronotum 

 slightly wider than long, coarsely closely punctured with smaller punctures 

 intermixed, elytra deeply striate, punctures coarse, close and shallow, 

 interspaces strongly rugose; side pieces of the meso-and metathorax densely

 with sutures 1 and 2 strongly chitinized, last two segments longer than 2 and 

 rapidly narrowed, segments of club indistinctly subdivided by a constriction 

 and a row of hairs; beak short; pronotum strongly muricate on the sides in front; 

 side pieces of the meso-and metathorax densely scaly; forecoxse widely separated; 

 proventriculus without distinct diagonal lines, the costal teeth numerous at 

 the base of the bristles, its disc finely sparsely granulate, chitinized on the sides, 

 the transverse lines strong; the ligula rounded at the apex. 



The type is Hylesinus aspericollis Leconte, 1876, the only species in our

with small punctures and decidedly muricate, more strongly in front; 



scutellum minute, depressed; the elytral striae strongly impressed and
