ISfEVV BRITISH SPECIES, ETC., IN 1861-6'2. 81 



pubescence in all is more or less reddish, es}3ecially at the 

 extreme apex ; and the smaller specimens have the inter- 

 mediate coxa3 generally lighter ; still the gradations are 

 scarcely perceptible. The best specific diagnosis, however, 

 is to be found in the abdomen, which has (or appears to 

 have) four longitudinal interrupted bands of ashy pubescence ; 

 and the basal segments have each three shallow foveffi, con- 

 sisting of one on each side, and a smaller depression on the 

 mesial line. 



The species appears to be much more common than 

 attenuatus.

 Kraatz, Ins. Deutschl. ii. 5*20, 35 j G. R. Crotch, 

 Zool. 8140 (1862). 

 Determined by Dr. Power, from specimens sent to him by 

 Mr. G..R. Crotch, found near nests of Formiica fiisca. 



There appears no reason why Erichson's name (which is 

 the senior by seven years) should be rejected; his description 

 merely differs from that of Kiesenwetter in mentioning the 

 elytra as fusco-testaceous with a pitchy disc, instead of 

 entirely pitchy, and such a variation must be allowed for a 

 species in which the elytra are more or less margined ; at all 

 events. Dr. Power was enabled to determine our insect 

 correctly by Erichson's diagnosis. 



Found by Mr. Crotch at Weston-super-Mare and Cam- 

 bridge ; also by the Rev. A. Matthews in Leicestershire, and 

 by Dr. Power and Mr. A. Haward in a rotten oak, near 

 Croydon.
