12 Mr. H. W. Bates oa the Longicorn Coleoptera 
nigro cincto: elytris puncto infra scutellum maculaque transversa 
atro-tomentosis, flavo cinctis, apice emarginatis, spina brevi termi- 
natis. Long. 53-8 lin.” of @. 
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, | met with it in abundance. 
The elytra are sinuate-truncate at the apex, and it is only in the 
inale 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 Adilis griseofasciatus of Serville (Ann. Soc. Ent. Fr. iv. 
p. 33), a common South-Brazilian insect, belongs to the present 
genus, and there are doubtless many other tropical American 
species yet to be added to it*. 
Genus PALAMEg, nov. gen. 
Body oblong, narrow ; elytra clothed with short sete. Head 
not much narrower than thorax or elytra. Antennz moderate 
in length, setose both above and beneath. Thorax with lateral 
spines extremely small and placed near the hind angles. Elytra 
free from ridges and lateral keels. Terminal abdominal seg- 
ment with the ventral plate in the males sharply notched ; ovi- 
positor in the female not prolonged, the apical segment being 
only a little longer than that of the male, with the ventral plate 
convex and truncated, and the angles of the truncature pro- 
duced. Legs stout; fore and middle tarsi dilated and fringed 
with hairs in the male; coxe and under surface of body also 
densely hairy in the same sex. 
In many points (for example, the setose elytra and antenne, 
shape of thorax, and style of coloration) the curious insect 
forming this genus shows a near degree of relationship with the 
Sporeti, especially with S. seminalis. It exhibits, however, an 
almost equally close approximation to the Colobothea, showmg 
that, notwithstanding the great amount of apparent difference 
between the elongate Colobothee and short flattened Levopz,
