and sparingly punctured, but two thirds of the anterior por- 

 tion are distinctly punctured, the punctures seen under the 

 microscope show fine central points ; the mesosternum is 

 widely arched like that figured for E. corpulentus (Ann. & Mag. 

 N. H. 1892, X, p. 236, pi. xix. fig. 1), and the marginal stria 

 closely follows the edge behind the prosternal keel only, surface 

 finely punctulate, the suture is marked by a fine stria which does 

 not meet in the middle, but it continues laterally halfway down 

 the metasternum, the sternal pits are very wide and shallow, 

 and their posterior limit is indicated by a feeble transverse 

 elevation. 



This species is most like E. corpulentus^ but ia larger. 



Bab. Kabylia. 



Eretmotus sinuattcoUis, sp. n. 



Orbicularis, convexus, niger, nitidus; fronte dense punctata; pronoto 

 utrinque conspicue sinuate ; prosterno striis anticis abbreviatis ; 

 mesosterao marginato, margine utriuque subtiliter striato ; femo- 

 ribus parce punctatis. 



L. 2| mill. 



Orbicular, convex, black and shining ; the head rather 

 densely punctate, lateral stria equally strong throughout its 

 length ; the thorax is anteriorly similarly and evenly punctate 

 like the head, but posteriorly, especially before the scutellura, 

 it is sparingly and finely punctured, it is markedly sinuous 

 laterally, and the anterior angles are obliquely truncate ; the 

 elytra, inner humeral slria cariniform and complete, 1 dorsal 

 very fine but traceable as complete, 2 more vague but appa- 

 rently dimidiate, 3 obsolete ; the pygidia are evenly and 

 somewhat closely punctulate ; the prosternum, the stride are 

 sinuous and shortened anteriorly, only occupying two thirds 

 of the keel length, the anterior lobe and the anterior part of 

 the keel are rather densely punctured, but the keel between 

 the striae is -more densely and coarsely punctate ; the meso- 

 sternum is bowed anteriorly, similarly to that figured for 

 E. sociator (' Annals,' 1892, x. p. 236, pi. xix. fig. 4), with a 

 clear marginal stria which follows the course of the edge, and 

 on eitiier side behind the coxse on the marginal edge is 

 a second fine stria, the marginal edge is punctulate, the foveas 

 are fairly deep ; the femora are slightly punctured. 



This species is most similar to E. sociator, but the pro- 

 sternal striae are shorter and the striation of the mesosternum 

 is different.
