Redt. with a little hesitation. They come from Chapada, Brazil 

 (H. H. Smith), and the Province del Sara, Bolivia (J. Steinbach). 



Genus Caulopsis Redtenbacher. 



Caidopsis Redtenbacher, Verh. Zool.-bot., Ges. Wien, XLI, p. 376 (1891); Saus- 

 SURE & PiCTET, Biol. Cent.-Amer., Orth., I, p. 388 (1898). 



This genus contains several species of rather small and comparatively 

 slender insects, which resemble the much larger species of Neocono- 

 cephalus. At least five species are known from South American 

 localities together with possibly two others. There are four sup- 

 posedly distinct species at hand. They, with still another, may be 

 separated as follows: 



Table for Separating the Species of Caulopsis. 

 A. Fastigium of the vertex with the apex acuminate, carinated below. 

 b. Size larger ( 9 . 37-44 mm.). Tegmina subacumlnate. 



c. Ovipositor fully one-half as long as the elytra (26 mm.). 



gracilis Redtenbacher ; 

 cc. Ovipositor less than one-half as long as the elytra (13 mm.). 



acuminata sp. nov. 

 hb. Size smaller (9,28 mm.). Tegmina with the apex rounded. 



oberthuri Bolivar. 

 A A. Fastigium of the vertex with the apex obtuse, rounded below. 



b. Smaller (cT, 24 mm.) cuspidata Scudder. 



bb. Larger (cf, 30 mm.) attenuata sp. nov. 



140. Caulopsis acuminata sp. nov. 



Most nearly related to C. gracilis Redtenbacher, but considerably 

 smaller. Antennae, as in that species, unusually robust and strongly 

 hirsute at the base and very long. The fastigium slender, acuminate. 

 Eyes round, depressed. Pronotum cylindrical, broadly and roundly 

 emarginate in front, truncate behind. Tegmina narrow, with few 

 veinlets, the costal field subhyaline, the apex somewhat acuminate. 

 Anterior and middle femora unarmed below, hind pair five- to si.x- 

 spined on the outer margin apically. 



Length of body, 9 , 36 mm., of pronotum, 5 mm., of tegmina, 

 36.5 mm., of hind femora, 15 mm., of ovipositor, 13 mm. 



Habitat. — The type and only specimen at hand comes from Corum- 

 ba, Brazil, where it was collected by H. H. Smith. This type belongs 

 to the Carnegie Museum.
