6S COLEOPTERA. 



considered British; the Athous elongating of Stephens' 

 Cabinet being, accordinfr to him, represented by an example 

 of Agriotes pilosus. Mr. Watei'house, liowever, expresses 

 a doubt as to the authenticity of the British origin of this 

 example, — a doubt amply borne out by the reference to 

 A. elongatus in the " Manual." 



24. Eros affinis, Payk. ; Kies., Ins. Deutschl. iv, 441, 4 ; 

 E. C. Rye, Ent. Mo. Mag. iii, 251. 



A single specimen of an insect which I have referred to 

 the above species was taken at Killarney in 1866 by a son of 

 Mr. J. Hardy, of Emden Street, Hulme, Manchester. At 

 the same time a pair of elytra of the same species were 

 found floating at the edge of the lake. 



E. affinh is smaller than E. Aurora^ and readily distin- 

 guishable from that species by its black thorax, of which the 

 anterior margin (which is minutely but sharply notched in 

 the middle) is obscurely reddish ; the small size of the 

 third joint of its antennae, which is but little longer than 

 the second; and its shorter elytra, the interstices between 

 the four elevated ridges of which are not broken up by sup- 

 plementary longitudinal striae, but are uninterruptedly trans- 

 versely reticulate. The scutellum is straightly truncate 

 behind ; the thorax broader, less contracted in front, and with 

 the discal fovea more oblong oval than rhomboidal. 



Kiesenwetter (1. c), continuing the comparison with 

 E. Auroraj states that the joints of the antennae are shorter 

 and thicker in E. affinis than in that species ; but, from an 

 examination of a German type of E. affinis (agreeing in 

 every other respect with his description) in the Brit, Mus., I 

 find the exact converse to be the case.
