Bradfield, Berks. One specimen taken by Dr. Joy, probably in dead 

 leaves. Ganglbauer records it as taken in Northern and Oenti-al Europe 

 with Formica ritfa. Thomson records it as found under fallen leaves. 



EUPLECTUS, Leach. 



Mr. Champion points out (Ent. Mo. Mag. xlv. (2 Ser. xx.) 1909, 

 74) that the two larger species of the genus Ettplectus, which are named 

 E. kunzei, Aube, and E. diiponti, Aube, must be referred to E. aubeanus, 

 Reitter, and E. hricmi^tcs, Grimmer, respectively. He is only speaking 

 for his own specimens, but it appears to be most probable that we do 

 not possess E. chcjwnti, Aube, at all as British. The real species is much 

 smaller than E. hrunneus. The localities given by me (Brit. Col. iii. 

 102) for E. kunzei must therefore be transferred to E. aubeanus, with 

 the addition of Guildford (Champion), Shiere (Capron), and the New 

 Forest, while those for E. duponti must probably be assigned to 

 E. brunneits, with the addition of Cobham Park (Champion). 



The following are the characteristics of the two species as given by 

 Champion : 



Elongate, narrow, flattened ; antennae rather 

 slender ; head with a deep, triangular notch 

 on the vertex ; elytra scarcely rounded at 

 the sides, subparallel, the humeri but little 

 swollen. Male : metasternum with a very 

 faintly impressed median line; fourth ven- 

 tral segment feebly sinuate at the apex, 

 fifth with a very broad transverse pit at the 

 base, the outer portions swollen, sixth trans- 

 versely flattened across the median third, 

 widely and shallowly emarginate at the apex, 



and bearing on each side a large flattened > 



tuberculiform prominence, which is clothed 

 behind with long hairs ; femora moderately 

 stout ; intermediate tibite curved . . E. aubeanus, Reitt. 



Broader, and rather convex ; antennae stouter ; 

 head with a shallower notch on the vertex ; 

 elytra distinctly rounded at the sides ; the 

 humeri swollen. Male: metasternum deeply 

 sulcate from near the base to the apex ; 

 fourth ventral segment drawn out into an 

 obtuse angle in the middle behind ; fifth 

 with a very broad, sharply-detined, semi- 

 cii'cular pit at the base, extending in the 

 middle to near the hind margin ; sixth, 

 more deeply emarginate at the apex, and
