Head triangular, not longer than broad ; clypeus with a distinct 

 longitudinal ridge ; antennae longer than the body in the 3" i the 

 second and third joints very short, the second moniliform, the third 

 turbmate, distinctly shorter than the preceding one, the fourth as 

 long as the basal three united and together with the four following 

 joints, which are each nearly equal in length, more or less dis- 

 tinctly compressed and slightly dilated on their inner edge ; 

 antermse in the ? shorter than the body, slender, filiform, the 

 second and third joints rather longer than in the other sex, the 

 third being slightly the longer of the two ; black, the three outer 

 joints, the apex of the eleventh excepted, yellowish white. Thorax 

 one-third broader than long; sides parallel and slightly sinuate 

 from the base to beyond the middle, thence slightly rounded and 

 obliquely converging towards the apex ; upper surface convex, 

 shining, impunctate. Elytra oblong-ovate, dilated posteriorly ; 

 upper surface convex, finely punctured, jet-black, each elytron 

 with three round spots or patches (two half-way between the basal 

 margin and the middle, the inner one large, the outer one smaller 

 and placed close to the lateral margin, the third subapical), and a 

 transverse band just below the middle, abbreviated at either end, 

 white or yellowish white. Legs almost entirely black. 



The entirely black legs in both sexes and compressed 

 joints of the antennae in the male, render this species 

 easy to be recognised. Diahrotica fraterna, mihi, with 

 which Mr. Jacoby has confounded this species, is much 

 narrower and quite distinct.
