12 HETEROMEBA. \BolitophayU8. 



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 tibise 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 Scliiodte (I.e. 

 pp. 545, 581, pi. viii. figs. 1, 8) ; the larva is white with the head and the dorsal 

 portion of the prothoracic 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 setae ; 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, occasionally brownish ; head large, almost semicircular in front, 

 with the eyes prominent, completely divided ; antennae 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 striae, which are comparatively feeble at apex, 

 but become very strong towards sides, interstices after the first three or 

 four next suture carmate ; legs long and not thickened. L. 6 mm. 



Male with joints 3-7 of the antennae clothed internally with rather 

 thick and long pilose pubescence, posterior tibiae with distinct spurs. 



Female with joints 3-7 of the antennae clothed with very short 

 pubescence, posterior tibiae 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. 



HELEBONA. Latreille. 



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- 

 pliagus 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.
