ACONOPHORA. oe 63 
The large size and black colour will easily distinguish this species, which in outline 
and shape of pronotal horn much resembles A. pubescens. A specimen from Lanquin 
is figured. 
3. Aconophora viridescens. 
Aconophora viridescens, Walk. List of Homopt. Ins. ii. p. 538°; Butl. Cist. Ent. ii. p. 351°. 
Aconophora guttifera, Walk. loc. cit. p. 539°. 
Hab. Norra America, East Florida *—Mexico (Mus. Brit. ex coll. Saunders *). 
A. viridescens is not represented in our collection; it is described as a broad species, 
with a very short pronotal horn, and is, apparently, of about the same size as 
A. marginata. No locality was given by Walker! for A. viridescens. 
4, Aconophora pubescens.

Mr. Butler says that his A. spathata is most nearly allied to A. pubescens: the 
examples from Guatemala in our collection form a connecting-link between the two 
insects, and appear to show that they are really synonymous. ‘The species is a rather 
large one, with the pronotal horn narrow and slender in comparison to its size. ‘There 
are also four specimens in our collection, from Dos Arroyos, Guerrero (H. H. Smith), 
Atoyac, Vera Cruz (Schumann), and Panzos, Vera Paz (Conradt), which I have somewhat 
doubtfully referred to this species ; they come too near it to be described as distinct in 
the present state of our knowledge of the genus. 
5. Aconophora laminata. 
Aconophora laminata, Fairm. Ann. Soc. Ent. Fr. sér. 2, iv. p. 294°. 
Hab. Mexico (coll. Spinola). 
I have taken great pains to identify this species, but have failed to do so; in the 
collections I have examined there are no specimens standing under A. /aminata which 
answer to Fairmaire’s description, and other species, in some cases more than one, do 
duty for it. Fairmaire distinctly says that the horn is slender and the femora black, 
the general colour being testaceous-brown, and the total length 12 mm.; the specimens 
in Signoret’s collection are evidently not rightly named, and the other specimens I 
have examined do not agree with the description. Stél in his table (Kongl. Sv. Vet.- 
Ak. Handl. viii. 1, p. 85) describes the insect as ‘‘corpore sordide flavo-testaceo vel 
olivaceo-testaceo, capite nigro, apice inter oculos et frontem flavescente limbato,”
