12 Ml'. H. W. Bates on the Longkorn Coleoptera 



nioTO cincto : elytris puncto infra scutellum maculaque transversa

natis. Long. 5^8 lin." cJ ? . 



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. 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 Pal am e, nov. gen. 



Body oblong, narrow ; elytra clothed with short setae. Head 

 not much narrower than thorax or elytra. Antennse 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 j coxae and under surface of body also 

 densely hairy in the same sex. 



In many points (for example, the setose elytra and antennae, 

 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, showing 

 that, notwithstanding the great amount of apparent diflference 

 between the elongate Colobothece and short flattened Leiopi,
