204 HEMIPTERA-HOMOPTERA. 
unlikely that the present insect may be referable to one or more of his species 5-10. 
It is, however, impossible to identify these from the descriptions, and several of his 
so-called species are evidently nothing more than varietal forms, from what Stal says 
himself; he makes no allusion either to shape or punctuation. C. triangulum, Walk., 
from Bahia, very closely resembles C. lenata, but the type in the British Museum is 
broken in two, and half is lost. 
A specimen from El Reposo is figured. 
11. Clastoptera stali, sp. n. (Tab. XII. fig. 26.) 
Oblonga, sat lata, nigra, nitidiuscula, metopidio flavo-vittato ; pronoto nigro flavo-marginato, subtiliter lineatim 
impresso ; scutello late flavo-maculato ; tegminibus utrinque et apice scutelli flavo notatis, clavo distincte 
punctato, apice fusco vix hyalino, callis permagnis nigris ; pedibus piceis, posticis obscure variegatis. 
Variat colore dilutiore maculisque diversis. . 
Oblong, rather broad, deep black, slightly shining; vertex with one, metopidium with two broad yellow bars; 
pronotum smooth, with traces of fine impressed lines, margined regularly all round with yellow; 
scutellum with a broad yellow patch before the base, and a small one before the apex; tegmina with the 
clavus distinctly punctured, especially towards the base, with yellow markings, which with the hinder 
mark on the scutellum form an irregular arc at about the middle, the apex fuscous, scarcely hyaline, 
the callosities very large and distinct, black ; underside black, in part testaceous ; legs pitchy-testaceous, 
with the tarsi darker and the hinder pair obscurely variegated with fuscous and testaceous. The species 
appears to vary considerably in colour and markings. 
Long. 33 millim. ; lat. 23 millim. 
Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith); Guatemata, Las Mercedes 
3000 feet (Champion); Panama, Bugaba and Volcan de Chiriqui 2500 to 4000 feet 
(Champion). 
The type-form from Las Mercedes, which is figured, seems very distinct; the others 
might be described as separate species on the colour-markings. C. stali appears to be 
allied to certain forms of C. funesta. 
12. Clastoptera chiriquensis, sp. n. (Tab. XII. fig. 27.) 
Parva, oblonga, vix nitida, testaceo-brunnea, testaceo-variegata ; capite pronotoque brunneis vel fuscis testaceo- 
vittatis, hoc distincte transversim lineatim impresso; scutello fere toto testaceo; tegminibus, preesertim 
clavo, plus minusve distincte punctatis, testaceo-brunneis testaceo-variegatis, maculé parva ad marginem 
apicem versus calloque distincte fuscis ; pedibus testaceis. 
A small, oblong, slightly shining species, variegated with light brown and testaceous ; head and pronotum dark, 
with testaceous bands, the pronotum distinctly impressed with transverse lines; scutellum entirely 
or almost entirely testaceous; clavus distinctly punctured; tegmina variegated with light brown 
and testaceous, sometimes obscurely darker in parts, with a fuscous spot at the margin towards the apex, 
and with well-marked callosities (the testaceous markings are arranged irregularly across the middle and 
spread up the sides); legs testaceous, tarsi darker, posterior pair in parts obscurely pitchy. 
Long. 3-3} millim. ; lat. 2 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
A small and fairly constant series. At first sight this species looks like C. lenata, 
but it is more shining and the general coloration is different.
