slope of elytra than elsewhere, upper-surface of abdomen more 

 sparsely pubescent, but in addition with numerous erect or 

 suberect setae, each side of base with a conspicuous golden 

 fascicle, middle of metasternum moderately clothed. 



Head moderately long, with a vague median line ; with 

 crowded punctures. Antennae moderately long, cylindrical 

 in section, thin about base, then somewhat dilated and 

 parallel-sided to near apex, where it is moderately dilated. 

 Protkorax lightly transverse, front angles rounded off, with 

 a rather large, but not very deep, medio-basal fovea; punc- 

 tures much as on head. Elytra moderately dilated to apex, 

 subsutural striae distinct; punctures rather dense and small 

 but distinct, becoming crowded at base. Upper-surface of 

 abdomen with a large excavation, semicircularly encroaching 

 upon convex median portion ; under-surf ace constricted in 

 middle. Metasternum rather strongly elevated (but not 

 acutely ridged) in middle, posterior slope with a small spine 

 projecting obliquely backwards, a larger and stouter one 

 between middle coxae. Front and hind tibiae somewhat 

 dilated at apex, middle ones with a strong, recurved, apical • 

 hook. Length, 2 mm. 



9 • Differs in being more dilated posteriorly, the meta- 

 sternum only gently convex along middle and unarmed, 

 abdomen more strongly convex on under-surface, and 

 scarcely depressed below level of metasternum, and the middle 

 tibiae unarmed at apex.

In general appearance like cylindricornis on a small 

 scale, but metasternum of male more convex, with a strong 

 and acute projection between the middle coxae, front tibiae 

 thinner and not notched, trie middle ones thinner, and 

 the .apical hook at a different angle, the abdominal 

 excavation is smaller and narrower, and the elytra are 

 without apical fascicles. The female may be distinguished 

 from the female of that species by its smaller size, somewhat 

 different abdominal excavation, different prothoracic fovea, 

 and by the absence of a golden line of clothing from the meta- 

 sternum. From regiits, which has somewhat similar antennae, 

 it is still more distinct. In some respects it is close to 

 gibbidus, but it is darker and more densely clothed, elytral 

 punctures distinct, metasternum of male more conspicuously 

 clothed along middle, and the intercoxal projection more con- 

 spicuous. The elytra and abdomen are somewhat paler than 

 the rest of the upper-surface. There is a projection from the 

 mouth, but it is too short and stout to be regarded as a bristle.
