54 and formed into a short neck. The antennæ are strong, and reach to the shoulders, joints 1 3 and 11 are of about equal length, middling, the former two subcylindric, joint 2 is small, rounded, 4-10 subequal and with the 11th oval. The thorax is small, only half as large as the head, rather narrowed, strongly transverse, twice as broad as long, slightly emarginated in front, the anterior angles rounded, contracted below the middle, subquadratic and prolonged at the base, posterior angles depressed, longitudinally divided by a deep furrow. The elytra are striated and, as well as the thorax, densely punctured and thinly pubescent. The legs are strong, simple and subequal, the anterior tibiæ are deeply notched, the first joint of the tarsi is as long as the two succeeding ones together, subcylindric, the 2nd triangular, the 3rd of a similar but more transverse form, smaller—all three have the apical angles acuminated, the 4th is large and deeply bilobed, the 5th middling, thin, the claws simple. The tarsi are altogether short and strong, the first joint is furnished with longer, the 2nd and 3rd with shorter stiff hair, whilst the 4th is strongly penicillated below. The anterior tibiæ are slightly spinose, the others more so.

I believe the only specimen of this insect which has hitherto come into my possession, and which has served as the type for the above description, to be a female.
