198 HEMIPTERA-HOMOPTERA. 
EICISSUS, gen. nov. 
Oblongus ; capite vertice brevissimo, metopidio compresso carinato; oculis magnis transversis, ocellis valde 
approximatis; pronoto longitudine fere duplo latiori, rugoso; scutello equilaterali, depresso; teg- 
minibus corio subhyalino, venis plus minusve crassis ; alis vena tertia haud furcata, venis transversis valde 
obliquis ; pedibus teretibus, tibiis posticis spina ante apicem armatis. 
Rather short, oblong, with the vertex extremely short, scarcely projecting at all beyond the eyes, which are 
large and transverse; ocelli very closely approximate ; rostrum long; pronotum about twice as broad as 
long, rugose; tegmina partly subhyaline, with the veins strongly marked; wings with the third vein 
from the outer marginal vein not forked, and the transverse veins very oblique ; legs slender ; posterior 
tibie with one spine a little before the apex, and the apex with a crown of short and rather stout 
spines. 
This appears to be a very distinct genus. It is, perhaps, somewhat allied to Carystus, 
Stal, which is peculiar to Australia and Tasmania. The female, at first sight, closely 
resembles certain species of Isside. 
1. Hicissus decipiens, sp.n. (Tab. XII. figg. 18, 13a, b.) 
Fusco-brunneus vel fusco-testaceus, interdum antice colore dilutoriori, rugose sculpturatus; rostro elongato ; 
sculptura pronoti tegminumque quoad sexum variante ; pedibus gracilibus, testaceis vel piceis. 
Mas angustior, postice acuminatus, pronoto dense subtiliusque rugoso, tegminibusque antice densius fortiusque 
punctatis, postice leviter vel vix reticulatis. . 
Femina latior et amplior, pronoto fortiter rugoso, tegminibusque corio (parte basali cum clavo fortiter 
punctata excepta) crasse reticulato, venis exstantibus. 
Of a dark fuscous colour, with the front half sometimes testaceous; metopidium sometimes light, abdomen 
black or pitchy, but variable; shape and sculpture varying in the sexes; legs slender, testaceous or 
pitchy. 
¢o. Narrower, with the tegmina less ample and when closed meeting behind in a point; pronotum and 
tegmina more finely sculptured, and the veins of the latter, as a rule, much less strongly marked; the 
sculpture, however, is somewhat variable. 
©. Broader, with the pronotum very strongly rugose, and the sculpture of the tegmina much coarser, the 
greater part of the corium being strongly reticulate with large outstanding veins. | | 
Long. 6-7 millim.; lat. max. 24-3 millim. 
Hab. Guatema.a, Chiacam, Senahu, and Sinanja in Vera Paz (Champion); Panama, 
Bugaba, Volcan de Chiriqui 2500-8000 feet (Champion). 
In the small series from the Volcan de Chiriqui the sc ulpture of the males is variable, 
but they all apparently belong to one species. I believe I am right as to the sexes, but 
as the specimens are mounted on card I have not examined all of them. 
A specimen from the Volcan de Chiriqui is figured. 
CLASTOPTERA. 
Clastoptera, Germar, Zeitschr. fir Ent. i. p. 187 (1839) ; Walker, List of Homopt. Ins. iii. p. 842. 
This genus contains a considerable number of very small and inconspicuous species, 
which are, apparently, widely distributed in North, Central, and South America. They 
are very variable in coloration, and it is almost impossible to distinguish them by
