the walls of which form a very fine longitudinal striation ; scutellum 

 very small ; elytra somewhat plane in the anterior part, but strongly 

 declivous laterally and behind, and having on each side nine highly 

 raised, sharp carinae, the intervals of which have a row of shallow 

 punctures ; under side and legs closely punctulate, anterior femora 

 not dentate inwardly at middle ; posterior ones not denticulate 

 underneath. 



Length 6-7A mm. ; width 2^-3 mm. 



This species differs from H. s<n inert, So2., in the less gibbose 

 prothorax and the much finer striolse of that part of the body ; the 

 anterior femora are not dentate, nor the hind ones denticulate 

 beneath as in H. yracilis, Gerst., with which //. velox, Fahr., might 

 prove to be identical.

Black, only moderately shining, palpi, tarsi, and basal joints of 

 antennae piceous-red ; head covered with equi-distant not closely set 

 punctures ; prothorax slightly broader than long, very little ampliated 

 laterally before the median part, and nearly straight from there to 

 the posterior angles which are only slightly rounded, the base is 

 moderately arcuate and marginate ; the outer margin is sharply 

 carinate, the anterior part is moderately convex, and the posterior 

 one depressed, especially towards the base ; the median part is 

 covered with equi-distant, not closely set and not deep punctures, 

 but the sides are strongly scrobiculate, the scrobiculation extending 

 on each side to about one-sixth of the width ; scutellum punctate 

 laterally ; elytra two and a half as long as the prothorax, sub- 

 oblong-ovate, and with the shoulders very sloping, convex and 

 gradually declivous behind, covered with closely set granules equi- 

 distant but smaller in the posterior part than on the sides, and 

 leaving a moderately broad, smooth, longitudinal space along the 

 suture from the base to the posterior declivous part ; legs strongly 

 scrobiculate, especially the femora, tibite very briefly pubescent, 

 tarsi clothed with fulvous, bristly short hairs ; prosternum produced 

 at apex into two strong, slightly divaricating spines; pectus scrobicu- 

 late ; abdomen deeply punctured, except the basal segment which
