This species closely approaches the slender forms of (E. bipunctatus. The pronotum 

 is elongated and slender, but less suddenly widened behind than in (E. bipunctatus. 

 The tambourine of the male elytra belongs to the type of (E. niveus. The first two 

 joints of the antennae are adorned beneath with a slender black line, the line on the 

 second joint being short.

Tribus ENEOPTERINiE.

The insects of this tribe have not such light forms as the (Ecanthinse. Indeed, they 

 have a more slender appearance, the elytra not being dilated as in the (Ecanthinse ; 

 moreover, the head is larger and the body stouter, the legs are shorter and more 

 robust and normal in form, the hind femora not being prolonged in a filiform shape 

 as in the (Ecanthinae *. The elytra of the males have a much narrower dorsal field. 

 Their tambourine, when present, is thus very complete, but not so delicate as in the 

 (Ecanthinse; and as the elytra are elongated, they are not obtusely rounded, but 

 terminate in a more or less pointed apical field. The speculum is variable in form — 

 ovate, elliptical, or rhomboidal, separated by one, rarely by two dividing veins. The post- 

 anal and first post-axillar veins are curved in the form of a C ; the first sends a branch 



* Except in the Indian genus Nisitrus, which makes a sort of transition.
