Fig. 1. C. glob ular is bears a cylindrical horn on the 
anterior part of the thorax, divided into four branches, 
each of which terminates in a hairy ball ; head black ; 
abdomen fulvous ; feet yellow. Length about three 
and a half lines. Fig. 2. C. furcatus, a larger species 
five lines in length ; the prothoracic expansion turned 
backwards, and projecting from the body, the apex 
bifurcated ; it is a native of Brazil, the former of 
Surinam and some other parts of America. Fig 3 
represents a new and singularly monstrous species 
from Mr. Hope’s collection, who obtained it from 
that of the late Rev. L. Guilding. Mr. Westwood 
names it C. biclavatns. The colour is obscure brown ; 
prothorax very large, the frontal part elevated into 
a long thick punctate and setose horn, the tip of 
which is dilated into a rounded knob ; the middle 
part also elevated into a similar horn, but shorter ; 
tegmina brown ; at the posterior angle there is a 
pale spot, as well as in the middle of the posterior 
margin. Length three lines ; expansion of wings six. 
A native of South America. 
Latreille includes among the homopterous hemip- 
tera the Gallinsecta, comprising the family coc- 
ci das ; also the Aphid^e, containing Psylla , Aphis, 
and Thrips. Mr. Haliday has recently formed the 
latter into a separate order, which he names Thysan - 
optera.
