.] HETEROMEBA. 47 



is bilobed ; the maxillary palpi have the last joint ovate or almost ovate, 

 slightly cultriform, and scarcely broader than the second and third 

 joints. 



The larva of H. bifasciatus (which has not occurred in Britain) is described and 

 figured by Schiodte (xi. 569, t. xvii ; . 1) ; it is about six times longer than broad, and 

 is gradually narrowed from the prothorax which is very large to the apex ; the 

 apical segment of the abdomen is simple ; the head and legs alone are corneous, these 

 parts being yellow and the rest of the body whitish ; the frontal margin is also nar- 

 rowly ferruginous ; the antennre, as in most of the allied larvse, are very minute ; 

 this la i va mines dead hazel and ash, and probably differs but little from that of our 

 species, which is attached to the oak. 



H. quercinus, Quens. Elongate, moderately convex, clothed with 

 silky and rather shining yellowish pubescence, head and thorax black or 

 pitchy, elytra yellow-testaceous, with the scutellary region, a patch on 

 each side before middle, a waved band behind middle, and the apex 

 black ; these markings are somewhat variable ; under-side brown or 

 yellowish ; head finely punctured, antennae rather stout, red ; thorax 

 about as long as broad, very closely punctured, but less finely than 

 head, with sides rounded in front and sinuate before the posterior angles 

 which are sharp and rather projecting ; scutellum transverse ; elytra a 

 little broader at base than thorax, gradually narrowed behind, more 

 coarsely punctured than thorax, rather shining ; legs reddish-testaceous, 

 first joint of posterior tarsi about as long as the rest taken together. 

 L. 4-6 mm. 



Male with the anterior femora clothed with white pubescence beneath, 

 the anterior tarsi dilated, and the elytra more parallel and the antennae 

 longer than in female. 



Female without pubescence on the anterior femora, and with the 

 anterior tarsi scarcely dilated, and the elytra a little dilated in middle. 



In decaying oak, &c. ; occasionally by sweeping ; rare ; Darenth and Coombe 

 Woods, Godstone (Surrey) and Wood Ditton, (Stephens) ; Darenth (Waterliouse) ; 

 Plumstead Wood, one specimen by sweeping (S. Stevens) ; Rusper, near Maidstone 

 (one specimen "in wet stuff," Gorhain) ; Leigh Woods, Bristol (in stump, E. 

 Wheeler). 



OSPHYA, Illiger. (Nothus, Olivier.) 



The members of this genus may be easily known from all the other 

 genera belonging to the family by the split or appendiculate tarsal claws 

 and the very strongly thickened and curved posterior femora of the 

 male ; the head is inflexed and the eyes rather large and plainly emar- 

 ginate ; the last joint of the maxillary palpi is strongly securiform, and 

 of the labial palpi almost cyathiform ; the thorax is transverse with all 

 the angles rounded ; the elytra are rather long and depressed, and the 

 body is soft and finely pubescent above ; the female closely resembles 

 certain species of Telephorus in general appearance ; the genus contains 

 five species, four of which are found in Europe and one in Xoith 

 America.
