BRACHINIDiE. — DROMIUS. 25 



Sp. 10. linearis. Elong-atus, fusco-ferrugineus, elytris punctato-

Ca. linearis. Olivier. — Dr. linearis. — Steph. Catal. No. 21. 



Of a more elongate and linear form than the other species of the genus : the 

 general colour of the upper parts is deep dusky ferruginous : the thorax rather 

 brighter than the head^ and the elytra somewhat of a pale hue, rather deeply 

 striated, the striae deeply punctate : the extremities of the elytra are more or 

 less suflfused with dusky : the under parts of the body are also ferruginous, 

 with the abdomen dusky : the antennae and legs are pale yellowish. 



The most common species of this genus, frequent in hedges 

 throughout the neighbourhood of the metropolis during the greatest 

 part of the year, hybernating abundantly beneath the bark of trees. 

 Found in the nidus of Bombus Donovanellus, in the isle of Arran, 

 by Dr. Leach, and supposed by him to be a new species, which he 

 proposed to call Dr. parasiticus. 



Sp. 11. glabratus. Oblongus, csneo-niger, elytris obsoletissime stri- 

 atis, disco impunctato, pedibus nigris. (Long. c. H lin.) 



Dr. glabratus. De Jean. — Steph. Catal. No. 22. 



Above glossy bronzed-black : the thorax somewhat quadrate, a little convex 

 smooth, with an impressed longitudinal hne : the elytra very obsoletely 

 striated : the under parts are black, with an aeneous tinge : the legs are dull 

 black, vdth the shanks and tarsi paler, or nearly brown. 



Found, though rarely, beneath stones near Hertford; not un- 

 common in the sandy heaths between Cobham and Ripley, Surry, 

 and at Southend. 



Sp. 12. femoralis. Niger obscurus, elytris substriatis, disco im- 

 punctato, appendiculis femoribusque basi palUdis. (Long. c. 

 U lin.) 



Ca. femoralis. MarsTiam. — Dr. femoralis. — Steph. Catal. No. 23. 



Distinguished from the preceding by its striated elytra, and from the following 

 by its elongate shape : it is of an obscure black above, with the head and 

 thorax rather shining ; the latter has a longitudinal groove, and is subqua- 

 drate : the elytra are rather strongly striated, but without any impressed dots : 

 the under parts are pitchy black, with the trochanters, coxte, and base of the 

 thighs pale testaceous brown,, the rest of the thigh black : the tibia; and tarsi 

 pale brown : the antennae are dusky, with their tips reddish. 



I possess two specimens of this insect (which somewhat re- 

 sembles Dr. pallipes, Ziegler), one of which I obtained from the 

 cabinet of the late Mr. Marsham, the other was found in the vicinity 

 of London.
