each represented by a few species, which are closely related to, or identical with, 
north temperate forms. 
Hypoceliodes is the most characteristic genus of the group in Tropical America, 
though very few species have hitherto been described.

A comparison of Faust’s typical species, 1. coronatus, from Venezuela, with that 
of one of the N.-American Orchestomeri, O. wickhami, Dietz, shows that they are 
congeneric *, Faust’s name having a few months’ priority. The species are numerous 
in Central and South America, and are chiefly recognizable by the deeply sulcate, 
unarmed or obsoletely dentate femora, the incrassate posterior femora, the short 
second ventral segment, which is acutely prolonged on each side behind, the excavate 
meso- and metasternum, the 7-jointed funiculus, and the strongly toothed tarsal claws. 
The tibie, as-in Auteutes, are sometimes subangnlate on the outer edge near the base. 
Fresh specimens are often more or less coated with a waxy fulvous secretion, as in 
Tixus. The thickened posterior femora are perhaps used for saltatorial purposes fF. 
a. Intermediate tibize rounded at the base externally; lateral tubercles of 
the prothorax prominent; metasternum excavate to the middle or apex 
(feebly so in O. pollinosus and O. dietzt).

* The S.-African genus Eyrius, Pasc., is very closely related to these insects. 
+ The European Rhinoncus perpendicularis, Reich., can jump a considerable distance, though the hind 
femora are not much thickened.
