EROS, Newman. 



This genus in its widest sense contains about fifty species, which 

 occur chiefly in North and South America ; one, however, has been 

 described from Tasmania, and one from Sitkha : nine occur in Europe, 

 of which five belong to the genus as at present constituted ; our 

 single species, E. Aurora, has only been found very locally in Scotland ; 

 its larva does not call for any particular remark ; it is elongate, linear 

 and depressed, of a brown colour, smooth and shining, with short an- 

 tennae and legs ; the head is moderately large, and the prothorax is 

 longer than any of the succeeding segments ; the segments are all slightly 

 narrowed in front, with the exception of the last, which is narrower than 

 the rest and rounded behind ; there appear to be no cerci ; a more or 

 less obsolete central channel runs down all the segments. 



E. Aurora, Herbst. (coccineus, Gemm.). Bather long and de- 

 pressed, widened behind ; head, under-side, antennae, and legs black or 

 fuscous black, thorax red with disc more or less fuscous, elytra scarlet, 

 dull ; head small, eyes rather large and prominent, antenna? rather stout 

 with second joint very short, third joint longer, not transverse ; thorax 

 small, narrowed in front, with five areolets, clothed with rather thick 

 reddish pubescence ; scutellum black or fuscous red, emarginate behind ; 

 elytra ample, considerably widened behind, with four strong coste on 

 each, the interstices being filled with a very distinct double row of 

 square cells or areolets ; under-side rather shining, breast with reddish 

 pubescence ; legs stout, black or fuscous black, claws reddish. L. 

 6-9 mm. 



Male with the antennae longer, the thorax subquadrate, narrowed 

 towards apex, and the seventh ventral segment of the abdomen deeply 

 emarginate in a semicircle at apex. 



Female with the antennae shorter, the thorax scarcely narrowed in 

 front, and the seventh ventral segment of abdomen entire. 



Under bark of spruce fir ; very local ; Scotland, Highlands, Tay nnd Dec districts 

 (Rannoch, Ac.); it has, however, been taken in some numbers in these localities by 

 Dr. Sharp, Mr. Champion, Mr. Kye, and others.
