CLASTOPTERA. 203 
I have with some reserve assigned the numerous specimens from the above-mentioned 
Central-American localities to this apparently rather common North-American species, 
as I cannot satisfactorily distinguish them from typical examples of C. obtusa, Say, 
in the Oxford Museum, presented by Mr. Asa Fitch; very few, however, of the 
North-American species reach so far south as Mexico. 
Among the specimens in our collection there is one from the Volcan de Chiriqui 
which is of a light testaceous-yellow colour, with the apex of the tegmina, a spot 
before the middle of the clavus, and the pronotal and frontal stripes fuscous ; this insect 
very much resembles C. lineatocollis, Stal (from California), except that the lines on 
the pronotum are not nearly so marked and the punctuation is less strong. It is 
possible that C. lineatocollis is only an extreme variety of this species. In the Vienna 
Museum collection there is a very pretty variety from California (labelled lineata, Sign., 
in litt.) with the head and most of the pronotum nearly white and the tegmina dark 
brown, with the irregular whitish bands strongly marked. The larger specimens in 
the Vienna Museum are labelled C. orbiculata, Signoret, in litt. 
We figure a specimen from Omilteme, and a variety from Tactic, Vera Paz. 
10. Clastoptera lenata, sp.n. (Tab. XII. fig. 25.) 
Oblonga, parva, haud nitida, brunnea vel fusco-brunnea, obscurior vel dilutior, variabilis, capite pronotoque 
albidis lineatim vel maculatim variegatis ; scutello albido-marginato; tegminibus, corpore subtus, pedibus- 
que brunneo-, fulvo-, castaneo-, albidoque-variegatis ; pronoto transversim impresse lineato ; tegminibus 
subtilissime punctatis, apice plus minusve hyalino vel toto colorato, callis nigris distinctis vel in colorem 
apicis mergentibus. 
A small, oblong, dull species, of a brown or fuscous-brown colour, variegated with whitish or testaceous- 
white, varying very considerably in depth of shade and in markings; the markings, however, of the 
head and metopidium are usually in distinct transverse fine light and dark lines, while the pronotum is 
more or less light, with two spots in the middle and two dashes in a line with these at the sides, or 
it is marked more or less in bands of light and dark; occasionally the whole disc of the pronotum is 
dark, or the markings are entirely absent and the whole is light; the scutellum, tegmina, underside, 
and legs are variegated with the same colour, and are very variable in this respect, but the normal 
marking appears to be an irregular band of whitish colour across the middle of the tegmina, which is 
more or less inclined to break up and spread; the subapical callosities are distinct in the specimens 
which have the tegmina hyaline at the apex, but in some cases, where the apex is only partially or 
scarcely hyaline, they are indistinct and merge in the ground-colour ; the sculpture of the tegmina is very 
close, rendering them in typical specimens quite dull, except at the extreme apex. 
Long. 3-4 millim. ; lat. 2-23 millim. 
Hab. Mexico, Ciudad in Durango 8000 feet (Forrer), Puebla, San Marcos, and 
Orizaba (Bilimek, in Mus. Vind. Ces.), Teapa in Tabasco (H. H. Smith); GuaTeMa.a, 
Balheu and San Gerénimo in Vera Paz, Cerro Zunil, El Reposo (Champion); Panama, 
Bugaba, David, and Volcan de Chiriqui (Champion). 
There is a large series of this species unnamed in the Vienna Museum collection. 
I have not seen the types of the various Clastoptera from Rio Janeiro described by 
Stal (Bidrag till Rio Janeiro-Traktens Hemipter-Fauna, ii. pp. 17, 18), and it is not 
*26 2 .
