Coleopterological Kotices, VII. 645 



wider than long, the flanks with coarse irregularly scattered punctures through- 

 out, the post-median depression feeble; marginal groove fine, with large shal- 

 low opaque and anastomosing punctures; apex transverse, feebly sinuate near 

 each angle, the latter acute and anteriorly prominent, the marginal groove 

 very fine, extending % the distance to the middle; median groove fine but 

 deep, very nearly attaining the apical margin. Scutellum irapunctate, the 

 median line feebly impressed. Elytra nearly ^5 longer than wide, about 2% 

 times as long as the prothorax, and. at base, equally wide, just visibly wider 

 behind the middle; base transversely rectilinear throughout; strice of the flat 

 ■upper parts rather fine but well impressed and very feebly punctate, the sec- 

 ond and third somewhat sinuous, the intervals relatively wide and feebly con- 

 vex, those of the vertical flanks very coarse, deep, approximate and sulciform, 

 with the punctures coarse. Metasternum with a strongly delimited median plate, 

 strongly punctured about the circumference on the sloping sides and very 

 densely near the middle coxse, the episterna very narrow, linear, concave, 

 opaque and glabrous. Middle and hind tibite each with a single small external 

 spine near apical third. Length 16.8-18.8 mm. ; width 5.6-6.0 mm. ; length of 

 the prothorax (in the smaller examjile) 4.0, of the elytra 9.7 mm. Honduras. 



Differs from the Brazilian leachi in its very much smaller size 

 and transverse and not visibly emarginate median parts of the 

 clypeal apex. 



Soranus imbellis. — Rather elongate and strongly convex, glabrous, 

 black and highly polished throughout above. Head small, scarcely ^ as wide 

 as the prothorax, impunctate, the posterior ambient impression shallow pos- 

 teriorly where it is indefinitely limited, becoming larger and deep anteriorly 

 along the supra-orbital ridges, enclosing also a small deep rounded depression 

 at each side of the base of the central process, the latter transverse, rather small 

 and feebly elevated, almost equally trilobed by very feeble longitudinal de- 

 pressions, the lateral lobes rectangular at apex, the median produced at tip in 

 a minute and nearly erect, acutely pointed process, from the base of which ex- 

 tend two very widely diverging, low, obtuse and straight ridges flexed outward 

 at apex, joining the supra-orbital ridge and minutely tuberculate at the point of 

 flexure; front between the ridges very feebly concave to the straight and trans- 

 verse marginal sulcus, the latter terminating at each side in a small acute 

 tubercle directed obliquely upward and outward at the base of the mandibular 

 ridge; clypeal edge transverse and virtually straight, angular and slightly 

 prominent at each side of the labral base; supra-orbital elevation rather short, 

 cariniform anteriorly. Prothorax rather small, fully }4, wider than long, trans- 

 versely subarcuate at apex, the angles moderately rounded; raarginal groove 

 very fine, impunctate, flexed inward fully ]4, the distance to the middle at 

 apex, receding gradually from the edge and becoming gradually more feeble; 

 post-median depression small but deep, coarsely punctate, the flanks with a few 

 coarse scattered punctures in its neighborhood; median groove strongly im- 

 pressed, entire. Scutellum impunctate, not impressed. Elytra nearly f-^ longer 

 than wide, 2% times as long as the prothorax and slightly wider, especially 

 behind the middle; striae rather fine, closer on the flanks, finely but distinctly
