The genus Aspona appears to be restricted as to the number of species : 
Canon Fowler describes and figures the following : 
ASPONA TURGESCENS, Fowl. 
B.C.A. Tab. IV. figs. 12, 12a-12e, p. 50. 
Habitat. —Guatemala. 
ASPONA INTERMEDIA, Fowl. 
B.C.A. Tab. IV. figs. 13, 13a-13e. 
Habitat. —Panama, Bugaba. 
ASPONA CUNEATA, Fowl. 
B.C.A. Tab. IV. figs. 14, 14a, 14b. 
Habitat .—Yolcan di Chirique. 
Tragopa aspera of Walker is probably a small species of Aspona nearly allied to 
A. bullata. 
Genus: ALCMEONE, Stal. 
Stal. Ofv. Kongl. Vet. Ak. Fork. xxiv. p. 558 (1867), xxvi. p. 256 (1869). 
Fowler (B.C.A. p. 72) remarks that this is one of the most distinct of the genera 
formed by Stal out of the old genus Hemiptycha of Germar. 
The species which are chiefly from Brazil, Cayenne, and Central America may be 
distinguished by their very broad pronota and the aculeate form of the posterior 
apices. 
Pronotum seen from above is inflated in front, and abruptly produced behind into 
a lanceolate point (Fowler). The humeral angles are but slightly produced, but the 
shoulder horns are obvious. 
The areas of the tegmina are narrow and elongated. 
ALCMEONE CENTROTOIDES. 
(Plate XXIV. figs. 6, 6a, 6b.) 
Hemiptycha centrotoides, Faiim. l.c. p. 317. 
Fairmaire gives as a description: obscurely yellow, with the suprahumera 
horns horizontal, and tipped, like the posterior apex, with black. 
Sometimes a brown colour occupies the greater part of the dorsum, and the 
yellow portion forms two oblique bands. 
This insect is obviously liable to considerable variation in colour, and the figure 
I give above only partly agrees with Fairmaire’s diagnosis in this respect. The
