ACONOPHORA. 65 
8. Aconophora compressa. 
Aconophora compressa, Walk. List of Homopt. Ins. ii. p. 541°. 
Hab. Mexico! (Bilimek; Mus. Vind. Ccs.), Morelia in Michoacan (Ff. D. G.), 
Xucumanatlan and Omilteme in Guerrero 7000 to 8000 feet (H. H. Smith). 
Walker's type is a male; the female is very different, being larger, with the pronotal 
horn longer and more slender. The specimen in the British Museum, named 
A. gilvipes, which was wrongly identified by Walker with A. pugnax, must apparently 
be referred to this species; through the kindness of Dr. Aurivillius I have been enabled 
to examine one of Stal’s typical A. gilvipes, which is quite different, and belongs rather 
to the A. pallescens group.. The male of 4. compressa is a very short stumpy-looking 
insect. 
The specimens from Morelia, above referred to, are a male and a female, and they 
are smaller, lighter, and more pubescent than the ordinary form of A. compressa, but 
can hardly be regarded as distinct. 
9. Aconophora laticornis. 
Aconophora laticornis, Walk. List of Homopt. Ins., Suppl. p. 134°. 
Hab. Mexico 1}, Jalapa and Jalisco (Hége), Omilteme and Xucumanatlan in Guerrero 
7000 to 8000 feet (H. H. Smith); Guatemata (Sallé), San Gerénimo, Cerro Zunil 
4000 feet, Totonicapam 8500 to 10,500 feet (Champion). 
Walker's type of A. laticornis is apparently a male ; at all events our specimens come 
so close to it that they cannot be described as distinct. The female, however, is a 
very different insect, having the pronotal horn very long (nearly as long in some cases 
as the distance between the base of the horn and the apex of the pronotum) and in 
some cases almost straight ; in one specimen the total length is 15 millim.; the horn, 
moreover, in the female, is comparatively slender, so that the name becomes a misnomer 
except for the male, in which it is short and broad, although in one or two specimens 
it is longer and intermediate in formation between the normal horn of the male and 
that of the female. The dark colour, shape of the horn, and the dark horizontal band 
on the tegmina will distinguish the species, of which there is a considerable series of 
both males and females, from Omilteme, in our collection.
