[29 . HEMIPTERA-HOMOPTERA. 
Most authorities are now content to follow the excellent diagnosis of this family as 
given by Stal, in which he has systematically and accurately separated its divisions or 
subfamilies, and which arrangement will be followed here. Mr. Pascoe has recently 
(Ann. & Mag. N. H., ser. 5, ix. p. 424 e¢ seg.) published a “ Note on the Classification 
of the Homoptera,” in compiling which he does not seem to have consulted Stal’s 
writings, as he makes no reference to them. In this classification he has elevated some 
of these subfamilies to family rank; and the only reason I have not quoted him in the 
synonymical notes above is that he describes his “‘ Fulgoride” as having the “head pro- 
longed anteriorly,” a character which I cannot consider as of at all universal application.

In this subfamily the anal area of the wings is reticulated, and, to use the further 
diagnosis of Stal, ‘‘ carina frontem et genas separante in latera clypei continuata.”

The extraordinary elongation, dilatation, and inflation of the head render the species 
of this genus of extremely easy recognition, and in a.work of this kind requires no 
further elucidation. The differentiation of the species, however, owing to their great — 
superficial resemblance, is a labour of greater complexity; and I have therefore given a 
rough synoptical key of the same. Of the five species thus enumerated three have 
already been received from Central America, the other two are distinguished by an _ 
asterisk.
