12 HETEROMERA. [ Bolitophagus. 
tives occurring in Central Asia, North and South America, India, 
Burmah, New Zealand, &c.; the eyes are entirely divided by the 
frontal plate ; the femora are long and project considerably beyond the 
sides of the elytra, and the anterior tibie are furnished with two spurs 
at apex, the intermediate and posterior pairs having one only ; they are 
moderate-sized insects, of dull and obscure appearance, with the upper 
surface rather strongly sculptured, but almost without pubescence. 
The larva and pupa of B. reticulatus are described and figured by Schidédte (Le. 
pp. 545, 584, pl. viii. figs. 1, 8); the larva is white with the head and the dorsal 
portion of the prothoracie segment, as well as the legs, pale ferruginous ; it is less 
linear than those belonging to the family that have been before described, being 
broadest about the middle ; the prothorax is as long as the two following segments, and 
is constricted in the middle so that it appears divided; the abdominal segments are 
furnished on each side with setose prominences; the anal segment is small and 
conical, and terminates in two very short cerci; the anterior legs are shorter than the 
other pairs; the pupa is much longer than broad, narrowed to apex, with the plates 
at the sides of the abdominal segments bifid, and produced at each side, and bearing 
short sete ; the cerci are comparatively long and are pointed ; the insect in all its 
stages is found in boleti. 
B. reticulatus, L. (crenatus, F.). Oblong, rather convex, dull 
black, occasionaliy brownish; head large, almost semicircular in front, 
with the eyes prominent, completely divided; antenne moderately 
long, robust, thickened towards apex, with joints 5—9 transverse and 
dentately produced internally ; thorax transverse, strongly emarginate 
in front, with the anterior angles projecting, and the sides notched, very 
closely and strongly punctured ; elytra deflexed and produced at apex, 
with deeply punctured striez, which are comparatively feeble at apex, 
but become very strong towards sides, interstices after the first three or 
four next suture carinate ; legs long and not thickened. L,. 6 mm. 
Male with joints 3-7 of the antenne clothed internally with rather 
thick and long pilose pubescence, posterior tibize with distinct spurs. 
Female with joints 3-7 of the antenne clothed with very short 
pubescence, posterior tibize with the spurs more or less obsolete. 
In fungi on birch and oak ; very local and, as a rule, very rare; it has only been 
found in the Tay district of Scotland, Rannoch, &c. 
HELEDONA, Laircille. 
Two species only appear to be known as belonging to this genus, one 
from Peru, and one which inhabits Europe ; they may be known from 
the preceding genus by their smaller size, and by the fact that the eyes 
are not completely divided, nor are the sides of the thorax distinctly 
crenulate ; the larva of H. agaricola closely resembles that of Bolito- 
phagus reticulatus, except that it is smaller, with all the segments trans- 
verse, and has the ninth dorsal segment of the abdomen broadly rounded 
behind and without appendages ; it is found in boleti.
