following taken together. Fore and middle tarsi in the male 
dilated and fringed with hairs. 
The chief character which distinguishes this group from Nys- 
sodrys is the dilatation and ciliation of the anterior and (in less 
degree) of the intermediate tarsi in the males. Some of the larger 
species of Nyssodrys have the male anterior tarsi much broader 
than those of the hind legs, but in none of them are they fur- 
nished with the marginal fringe of hairs. The Hyletti are some- 
what larger insects than the Nyssodryes, and the shape of their 
thorax is somewhat different, the lateral spines being in the 
form of large or distinct tubercles, and placed near the middle 
of the sides. The genus approaches Acanthocinus and Graphi- 
surus (groups characteristic of North America and Europe) 
nearer than any we have yet passed in review.

Leiopus coenohita, Erichson, Consp. Ins. Col. Peruana, p. 145. 
“ L. fuscus, dense cinereo-tomentosus, supra flavo irroratus, scutello 
nigro cincto : elytris puncto infra scutellum maculaque trans versa 
atro-tomentosis, flavo cinctis, apice emarginatis, spina brevi termi- 
nals. Long. 5|— 8 lin.” c? ? . 
The examples which served Erichson for his description were 
obtained by Von Tschudi in Eastern Peru, in the same forest 
region where, further east, at Ega, I met with it in abundance. 
The elytra are sinuate-truncate at the apex, and it is only in the 
male that the outer angle of the truncature is produced into a 
spine ; in the female both angles are acute. The thoracic tuber- 
cles are rather small, but stand out distinct from the sides of 
the thorax. 
The jEdilis griseofasciatus of Serville (Ann. Soc. Ent. Pr. iv. 
p. 33), a comm^on South-Brazilian insect, belongs to. the present 
genus, and there are doubtless many other tropical American 
species yet to be added to it*.
