132 HEMIPTERA-HOMOPTERA. 
2. Epibidis brunnea, sp.n. (Tab. XIII. figg. 6, 6a.) 
Fusco-brunnea, partibus anticis plus minusve castaneis, venis tegminum obscurioribus ; pracedenti affinis, sed 
major, colore magis uniformi, secundo articulo antennarum tenuiori et minus asperato, venis tegminum 
minus evidenter granulatis, et lined subtili testacea pone medium deficiente, facile distinguenda. 
Mas segmento ultimo ventrali fortiter emarginato, processu ad medium brevi trifido, lamina utrinque sat lata 
ad apicem subtruncata ; stylis brevibus, acutis, ad basim separatis ad apicem approximatis, 
Femina segmentis ventralibus apicem versus profunde emarginatis, ovipositore prelongo. 
Of a fusco-castaneous colour, larger than the preceding, with the anterior parts a little lighter in places, and 
the veins of the tegmina dark and less evidently granulose, this, however, is mainly due to the colour, as 
the granulations themselves are quite as strong; the second joint of the antenn is a little more slender 
and less asperate ; the tegmina have no irregular thin testaceous line behind the middle; the legs are 
unicolorous, pitchy-castaneous ; occasionally five spines are visible on the posterior tibie. 
Male with the last ventral segment broadly emarginate, with a small trifid process on its hind margin, and 
with two plates, one on each side, which are truncate at the apex; the styles are stout at the base and 
sharp at the apex, where they are approximate. 
Female with the ventral segments deeply emarginate and the ovipositor very long. 
Long. cum tegm. 9 millim.; lat. ad hum. 3 millim. (d @.)

GONIOLCIUM, gen. nov. 
Capite brevi, lato, oculis permagnis; vertice transverso ; fronte modica, cariné ad verticem bifurcaté ; antennis 
articulo primo lato, subtriangulari, secundo hoc plus minusve distincte longiori; pronoto vertice vix 
longiori, carinis validis, lateralibus ad medium fortiter angulatis et basim attengentibus; scutello 
tricarinato ; tegminibus venis distincte asperatis ; tibiis posticis bispinosis. 
Head short, broad, with very large eyes; vertex small, transverse; forehead moderately large, frontal keel 
slightly forked at the forehead, the fork sometimes being little more than a thickening, sometimes 
distinct ; antennez with the first joint large and broad, subtriangular, the second more or less distinctly 
longer than the first, stout and thick, the last setiform joint long; pronotum about as long as the vertex, 
with three distinct carinz, the side ones being strongly angled and reaching the base; scutellum large, 
tricarinate ; tegmina with the veins distinctly asperate ; posterior tibie bispinose. 
The peculiar angled side-keels of the pronotum, which reach the basal margin, 
together with the asperate veins of the tegmina, the short broad head, and general 
facies, serve to distinguish this genus. I have included under it two species: the first 
of these, however, has the characteristics more marked than the second, and differs 
from it somewhat in the formation of the antenne. 
1. Goniolcium granulosum, sp.n. (Tab. XIII. figg.7, 7a, 2; 8, ¢.) 
Partibus anticis nigricantibus (interdum fusco-testaceis vel plus minusve testaceis), albido-testaceo variegatis ; 
fronte basi nigra vel fusca, parte apicali albida, clypeo fusco; antennarum articulo secundo annulato ; 
carinis pronoti scutellique albidis; tegminibus pellucidis, vittis duabus irregularibus et tertia parte 
apicali interne nigrescentibus, venis nigro-granulosis ; pedibus albidis, nigro concinne variegatis. 
Mas tuba anali modicé in hamum magnum acutum producti, stylis longis robustis fere rectis, apicem versus 
sensim dilatatis, truncatis. 
Femina tub4 anali sat longa, stylo anali distincto, ovipositore prelongo fortiter curvato. 
A small species, subparallel, gradually narrowed to the apex; anterior parts dark, variegated with whitish- 
testaceous, but somewhat variable in colour; forehead with the basal half dark and the apical half 
whitish, the clypeus fuscous; frontal keel very slightly bifurcate at the vertex, the bifurcation sometimes
