CLASTOPTERA. 205 
13. Clastoptera flavifrons. (Tab. XII. fig. 28.) 
Clastoptera flavifrons, Germ. Zeitschr. fiir Ent. i. p. 189°. | 
Hab. Mexico (coll. Signoret, in Mus. Vind. Ces.).—Brazil 1. 
This is a small, oblong, brownish species, with the head, pronotum, and scutellum of 
a yellowish colour; structurally it closely resembles one or two allied forms, and may 
be only a variety of one of them. The species from Mexico in the Vienna Museum 
is figured. 
14. Clastoptera rufescens, sp. n. 
Parva, nitida, capite, pronoto, scutelloque rufescentibus, metopidio ad medium testaceo utrinque transversim 
rufo-fusco testaceoque lineato ; pronoto sat fortiter transversis lineis impresso, antice testaceo-marginato ; 
tegminibus nitidis, hyalinis, sat fortiter punctatis, venis rufescentibus, callis nigris, distinctis ; corpore 
subtus nigro; pedibus rufo-testaceis. 
A small shining species, with the head, pronotum, and scutellum rufescent; pronotum rather strongly 
impressed with rugose lines, the anterior margin testaceous; tegmina shining and transparent, rather 
strongly punctured, with the veins rufescent and without markings, the subapical callosities very distinct, 
black ; abdomen black; legs rufo-testaceous. 
Long. 3 millim. ; lat. 2 millim. 
Hab. Mexico, Chilpancingo in Guerrero 4600 feet (. H. Smith). 
This species appears to be allied to the North-American C. canthocephala, Germ., 
which is, however, a darker and less shining and transparent insect. 
We have also received a specimen from Teapa in Tabasco, which I at first referred 
to this species, but it is rather larger, with a fuscous patch at the margin of the 
tegmina and very small testaceous apical callosities. 
15. Clastoptera unicolor, sp.n. (Tab. XII. fig. 29.) 
Oblonga, parva, postice nonnihil dilatata, sordide testacea, nonnihil nitida, pronoto vix transversim lineis 
impresso; tegminibus plus minusve distincte, interdum sat fortiter, punctatis, callis modicis, nigris, 
_distinctis ; pedibus testaceis. 
A small, oblong species, more or less dilated behind, of a uniform dirty testaceous colour (occasionally reddish), 
with the pronotum faintly impressed with transverse lines, and the tegmina (especially the clavus) more 
or less distinctly punctured ; legs testaceous; underside somewhat pitchy. 
Long. 3 millim.; lat. 2 millim. 
Hab. Mexico (Bilimek, in Mus. Vind. Ces.), Vera Cruz (H. H. Smith); Guaremana, 
San Gerénimo (Champion). | 
This insect appears to be inseparable from C. arkansasensis, Fitch, in litt., and is 
also allied to C. rufescens and C. xanthocephala, Germar, as well as to C, testacea, 
Fitch ; the last-mentioned species is longer, and differs in several particulars. 
A specimen from Vera Cruz is figured.
