I do not know the sex of tbe specimen described, but its affinity 

 seems more to E. blagravii, Casteln., than to E. olliffi, Bates, 

 therefore I think it likely the anterior tarsi are similar in both 

 sexes. 



Its smaller size, less dilatate prothorax, and less strongly striate 

 elytra at once distinguish it from E. blagravii, while from E. olliffi 

 its more elongate form, and less globose prothorax, separate it 

 readily.

A single specimen is in my collection, taken at Burrawang on 

 10th Nov., 1890, on which the following description is founded : — 



(J. Form short, robust, head small. Black, legs and parts of 

 mouth reddish. Head small, smooth ; a strong transversal 

 impression behind eyes ; frontal impressions strong, diverging 

 behind ; clypeal suture strongly impressed ; a narrow lateral 

 groove with raised external edge, extending from back of each eye 

 to base of mandibles, space between this groove and frontal 

 impression raised ; eyes round, prominent, without post-ocular 

 prominences. Prothorax short (3 x 3-|mm), rather depressed on 

 disc, declivous on sides, broadest about middle, lightly emarginate 

 in front, — the anterior angles being broadly rounded, margined, 

 and slightly advanced ; sides lightly rounded on anterior half and 

 a little narrowed to the front, shortly and decidedly rounded 

 behind ; lateral border narrow, reflexed ; a small protuberance 

 extending vertically downwards in the form of a ridge on each 

 side, just before the basal angles, — these obtusely rounded ; 

 median line very strongly impressed, not reaching either margin ; 

 the marginal channel widening inwards on each side a little before 

 the basal angles, thus causing the posterior part of the prothorax 

 to appear sinuate ; three setigerous marginal punctures on each 

 side, the 1st just behind the anterior angles, 2nd about middle, 

 3rd just after the prothorax begins to narrow behind. Elytra 

 shortly oval (6| x 4^ mm.), rather depressed on disc, declivous on 

 sides and behind, striate ; strise strongly marked on disc, very
