118 MANDIBULATA. COLEOPTERA. 



Broscus may be known from the otlier Harpalidse, by the form of 

 its thorax, which is very mueli attenuated posteriorly, depressed at 

 the angles, and apparently remote from the elytra: the body is 

 elongate, the mentum deeply notched, the emargination bearing an 

 obtuse lobe in its centre, the four basal joints of the antennae are 

 naked, and the head is large, whence the genus has been termed 

 Cephalotes by Bonelli; but that name having been employed 

 many years previously for a genus of bats, cannot be here retained : 

 its location is not satisfactory.

JVo. 198. 



Black, slightly glossy : head sparingly punctate : thorax very convex, obsoletely 

 wrinkled transversely, with a dorsal channel ; the base rather rugged, without 

 angles, and rather distant from the elytra, which are somewhat opaque, with 

 the shoulders rounded, convex above, very delicately punctato-striated, with 

 the interstices flat and smooth, and eight or nine remote impressed dots on 

 the margin : the body beneath and legs black : the antennae with the seven 

 last joints fuscous: the palpi piceous, with the tips of the joints pale rusty- 

 piceous. 



Common beneath marine rejectamenta, especially on the coasts 

 of Sussex, Suffolk, Norfolk, Yorkshire, Northumberland, DcA^on- 

 sliire, and Glamorganshire. Abundant also near Southend. 



Genus XLVII. — Stomis, Clairville, 



Piilpi rather elongate ; external maxillary with the last joint as long again as 

 the third, ovate-truncate ; the second very slender, internal attenuated ; labial 

 with the third joint elongate clavate, the terminal ovate-truncate : labrum 

 transverse, emarginate anteriorly : mandibles acute, elongate, not denticulate 

 internally; the right one with a notch on its inner edge near the centre: 

 mentum transverse, not very deeply notched anteriorly, with a simple lobe. 

 Antennas with tlie three basal joints naked, the third and fourth of equal 

 length : head subovate : thorax elongate-cordate : elytra ovate : wings none : 

 anterior tarsi of the males with three dilated joints. 



Distinguished by its slender form, its acute elongate mandibles, 

 emarginated labrum, slightly notched, transverse, simple-lobed, 

 mentum, and short ovate-truncate terminal joints to the palpi.
