Habitat. — The collection contains two specimens, a pair, which 

 are referred here. One is a nymph, and was taken during December, 

 the other is mature, and was collected in July. 



The specimens examined by the writer vary considerably in some 

 structural features, and represent a single variable species, or else two 

 or more distinct forms. 



Genus Paracornops Giglio-Tos. 



Paracomops Giglio-Tos, Boll. Mus. Zool. Anat. Corap. Torino, IX, No. 184, p. 31

96. Paracornops aquaticum Bruner. 

 Paracornops aquaticum Bruner, Proc. U. S. Nat. Mus., XXX, p. 662 (1906). 



Habitat. — This species is represented by a male specimen which 

 J. D. Haseman secured on December 6, 1908, at Morro do Para, 

 Bahia, Brazil. 



All the species of the genus Paracornops appear to be fairly common 

 at certain localities where they frequent aquatic plants. They, can be 

 collected by beating such vegetation.

The genus Copiocera is composed of medium-sized, slender, elongate 

 locusts, in which the hind tibiae are without the lamellate edges common 

 to the insects belonging to several of the genera just mentioned on the 

 foregoing pages. These insects also have the valves of the ovipositor 

 of the females slender and finger-like, without digging edges. With 

 the exception of a single species, all of its representatives belong to 

 tropical South America. Eight species have been described hereto- 

 fore, while a ninth is now added.
