from the prothorax. The metasternum — so much shorter than usually 

 obtains in this sub-family, would seem to connect it with the Coelomeio- 

 pince (through Polypleurus) ; but it unmistakably belongs to the present 

 sub-family, the remarkable notch in the anterior margin of the epis- 

 toma (PI. II, fig. la) clearly connecting it with Zophobas. Perhaps the 

 most singular feature is the absence of the long hook, or claw, to the 

 inner lobe of the maxillae. 



E. Jansonii, n. sp. (PI. II, figs. 1 and la). 



Length 12 lines. —Elongate ; entirely of a dull black, with a slightly bluish 

 bloom : head and prothorax impunctate ; on the latter a transverse, sinuous im- 

 pression at the middle, near the base, and one or two others smaller, near the hind 

 angles : elytra, each with (besides a short sutural sulcus) nine well-marked longitu- 

 dinal sulci ; these are regularly and closely impressed with rather large, rounded 

 punctures, which nick their sides ; the intervals — save the first - are narrow, con- 

 vex, and impunctate ; the 1st is joined to the 7th near the apex, the 2nd to the 6th, 

 and the 3rd to the 5th, enclosing the 4th ; the 8th is shortened behind, and — as 

 well as the 5th and 7th— joined on to the 6th a little before attaining the shoulder : 

 under-side, legs, &c, glossy black ; the abdomen very faintly longitudinally 

 wrinkled, and sparingly and minutely punctulate. 



Hab. Nicaragua, Chontales. 



Discovered by Mr. E. Janson, Jun., to whom I dedicate it.

From Zophobas the present genus differs in having the last joint of the labial 

 palpi briefly securiform ; the eyes smaller and much narrower ; the antennw shorter 

 and stouter, with joints 9 — 10 transverse, 11 obliquely truncated, the outer apical 

 angle produced ; the prothorax relatively shorter and broader, the lateral margins 

 crenulated : the elytra relatively shorter, ovoid, much more convex, widest behind 

 the middle, somewhat abruptly declivous behind, and more pointed at the 

 apex : the legs relatively stouter, the tibia? scarcely perceptibly curved : the metas- 

 ternum much shorter, being no longer then the 1st abdominal joint in its shortest 

 part : the intercoxal process relatively broader and more rounded anteriorly : the 

 prostemal process much more strongly produced and pointed- behind ; and the meso- 

 sternum sub-horizontal. The body is apparently wingless. 



The majority of the above characters were pointed out by 

 Lacordaire (G-enera, v, p. 378, note) when stating the advisability of 

 erecting it into a distinct genus. The more convex form and the elytra 

 gradually widened from the base to beyond the middle, and abruptly 

 declivous behind, give quite a different facies to that of Zophobas, to 

 which, however, the present insect must be closely related, notwith- 

 standing its short metasternum. There is a pecularity in the mentum 

 (shared by the present genus with Zophobas), which has its outer
