DRACHlNIDiE. — DROMIUS. 23 



Oxfordshire, as my friend, Mr. I. O. Westwood, F. L. S., informs 

 me ; and in Dorsetshire and Shropshire : it appears, therefore, to 

 be generally diffused.

 ceniibus macula humerali ohsoletlssimd pallidiore, tibiis tarsisque 

 pallidej'usds. (Long. e. li lin.) 



Dr. impunctatus. Kirby, MSS. — Steph. Catal. No. 17. — Dr. spi- 

 lotus var.? De Jean. 



At first sight this species greatly resembles Dr. foveolus, but it is readily distin- 

 guished from it by the absence of the two impressed dots, so conspicuous in 

 that insect, and, upon a closer inspection, by the presence of wings. Its 

 upper surface is of an opaque brassy or dusky-black, with the elytra brassy- 

 brown, and each marked on the basal angle with an obsolete pale spot: the 

 elytra are slightly convex and obsoletely striated ; the tip is obliquely trun- 

 cated, and sUghtly sinuated : the thorax is rather transverse, with an impressed 

 longitudinal line : the under parts of the body and the antennae are black ; 

 the legs are pale brown, with the thighs dusky. In one of my specimens there 

 is a very slight appearance of a pale spot near the apex of the elytra. 



It is probable that this insect may be simply a variety of Dr. 

 spilotus of De Jean, which, from his description, appears to be a 

 variable species ; it seems to differ, so far as I learn from his account, 

 in wanting the pale line near the suture, the apical spot on the 

 elytra, and in having the legs of a darker colour ; but it is pro- 

 bable that these are variable characters, arising from the age of the 

 individual. I have hitherto examined five specimens only ; two in 

 the collection of my friend, N. A. Vigors, Esq., F. L. S., &c., one 

 in Mr. Stone's, and two in my own cabinet; one of the latter I 

 found among Mr. Marsham's Carabidse, and the other, as well as 

 Mr. Stone's specimen, was taken near London. 



Sp. 7. humeralis. Brevis, niger, nitidissivius, elytris maculis duabus 

 azit quatuor paU'uUs, altera humerali, altera {ncepe obsoleta) in 

 disco elytrorum. (Long. c. 1| lin.) 



Dr. humeralis. Curtis, MSS.— Steph. Catal. No. 18.— Dr. qua- 

 drillum ? De Jean. 



Above of a deep glossy black ; the elytra with a conspicuous rhomboidal yel- 

 lowish-white or ochraceous spot at the basal angle, and sometimes a smaller 

 one on the disc towards the apex : they are rather strongly striated, especially 

 near the suture, and between the striae are slightly impressed points; the 

 under parts are also deep glossy black, the tarsi rather obscure or brownisli : 

 the basal joint of the antennae is sometimes pale brown. 



Closely allied to Dr. quadrillum of De Jean, but the anterior
