Black ; the palpi, the live basal segments of the antennae, the 

 anterior and middle legs, and the posterior tibiae, yellowish-brown ;, 

 the six apical segments of the antennae fuscous ; labrum obscure 

 brown. 



Head broader than long, frontal elevations ovate but slightly 

 raised and small ; eyes entire and oblong. Antennae about two- 

 thirds the length of the body ; first segment elongate, second 

 small, third and fourth equal, fifth slightly shorter ; from the 

 sixth to the eleventh the segments are more or less nearly equal. 

 Prothorax about twice as broad as long (not more than three 

 times, as Jacoby states), posterior margin widely arched, sides 

 narrowly margined, nearly straight, anterior angles somewhat 

 broad and slightly produced, each of the anterior and posterior 

 angles with a single seta : surface strongly convex and entirely im- 

 punctate. JScutellum triangular, with apex rounded and surface 

 impunctate. Elytra distinctly broader at base than prothorax, 

 widened behind ; each elytron very minutely and closely punctate, 

 the punctures more or less arranged in longitudinal rows, but not 

 regularly enough to allow of the rows being exactly counted. 

 Underside smooth, impunctate, sparsely covered with fine hairs; 

 prosternum distinct, but narrow ; mesosternuni slightly emargi- 

 nate at its base. 



Length, 4 mm.

The following are rather free translations of Motschulsky's 

 original descriptions of four other species, the location of the 

 types of which I do not know. E. dimidiata was original^ 

 described in French, and the three which follow it in Latin : —

With the broadened form of the preceding species (E. latissima), 

 but of testaceous colour, the posterior half marked with a 

 blackish-brown patch, bordered with testaceous and delimited 

 obliquely in front towards the suture ; eyes black; prothorax less 

 transverse and more rounded at the sides ; posterior femora and
