OPHIDERMA.—TELAMONA. 148 
the subtriangular and stylate apical third cell of the tegmina; the shoulders are very 
slightly prominent, and the sides of the pronotum are very gradually and evenly rounded 
to the apex, which is very blunt and reaches nearly to the apex of the tegmina. 
1. Ophiderma mus, sp. n. (Tab. IX. figg. 3, 3a.) 
Latius, sat robustum, capite magno subtiliter punctato, testaceo; pronoto densius fortiusque punctato, murino, 
vel griseo-purpureo, griseo-variegato, linea centrali elevata nigra, punctisque plerumque obscuris, humeris 
vix prominulis, dorso a latere viso leviter sed distincte sinuato, ante medium perpaullo elevato; tegmi- 
nibus hyalinis, basin versus punctatis, basi medio et apice plus minusve infuscatis ; pedibus testaceis. 
A broad and robust species; head large, finely punctured, and the eyes large and not very prominent ; 
pronotum of a greyish-purple or mouse-colour obscurely variegated with grey, with a dark central line, 
and with the colour obscurely arranged in bands of irregular breadth behind the middle; punctuation 
close and rather strong, finer on the metopidium, the punctures being for the most part dark ; shoulders 
very slightly prominent; dorsum, if viewed from the side, feebly but distinctly sinuate, very slightly 
raised a little before the middle and scarcely depressed in the centre; tegmina hyaline, with the basal half 
more or less punctured, and with a fuscous patch at the apex, and a testaceous band, fuscous externally, 
in the middle; legs testaceous, claws and apex of the tibize infuscate.

Hille, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1867, p. 555; ibid. 1869, p. 235. 
The single species referred to this genus scarcely differs from Oxygonia, except 
in the form of the dorsum, and it ought, perhaps, to be included under it, as the 
character afforded by the presence or absence of a discoidal area on the corium is of 
doubtful value.

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). —Brazi ', Botafogo and 
Rio Janeiro. 
The Panama insect is rather larger and more strongly sculptured than any specimen 
of H. pacifica I have seen, but it can scarcely be regarded as belonging to a separate 
species.
