Hypulus.] HETEROMERA, 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 Schiédte (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 tine rest of the body whitish; the frontal margin is also nar- 
rowly ferruginous ; the antenne#, as in most of the allied larve, are very minute; 
this larva mines dead hazel and ash, and probably differs but little from that of our 
species, which is attached to the oak. 
HZ. 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, antenne 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; seutellum 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 antenne 
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 (Waterhouse) ; 
Plumstead Wood, one specimen by sweeping (S. Stevens) ; Rusper, near Maidstone 
(one specimen ‘‘in wet stuff,’ Gorham); Leigh Woods, Bristol (in stump, EH. 
Wheeler). 
OSPHYA, Illiger. (Vothus, 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 North 
America,
