Orbillus is an African genus containing six known species. These 

 insects are of average size and very probably have special food-habits 

 and definite haunts.

The genus Catantops is confined to the Old World with its center 

 of abundance in Africa. Its members are, as a rule, medium-sized 

 insects of modest coloration, though some of the species are brightly 

 and strikingly colored. Kirby lists one hundred and three, and a 

 supposedly additional species is described in this paper. Karny has 

 given us a very comprehensive review of the genus in his article on 

 "Die Orthopterenfauna des .-Egyptischen Sudans," pp. 43-86. Ap- 

 parently this genus is in the Old, what Melanopliis is in the New 

 World, i.e., the prevailing group of generally distributed common 

 grasshoppers.

There are three specimens, one male and two females from Batanga, 

 where they were collected by F. H. Hope. C. M. Ace. No. 5293. 



39. Catantops uniformis n. sp. 



A single male specimen of another species of the genus is before me. 

 It seems to be new and in the arrangement of species belongs near
