126 HEMIPTERA-HOMOPTERA. 
magno, convexo ; pronoto antice angulato; scutello sat magno; tegminibus nitidis, subpellucidis, ad latera 
subvitreis, disco fuscato ; corpore subtus pedibusque testaceis, plus minusve piceo variegatis. 
Femina segmento ultimo ventrali ad medium diviso, processibus duobus instructo, processu anali magno ad 
basim latiori, apicem versus sensim angustato. 
A rather large, subovate species ; head small, the vertex distinctly produced before the eyes, longer than broad, 
strongly excavate, and with the sides much raised, so that viewed from the front they appear to be 
cornute, the raised parts at the base having a black spot which makes them more conspicuous; forehead 
dark, with minute light markings, lagenoid, broader before the apex and gradually narrowed to the 
vertex ; pronotum angular in front, straight behind; scutellum rather large; tegmina broadest before 
the middle, subpellucid and almost vitreous at the sides, dark on the disc; underside and legs testaceous, 
variegated with pitchy colour, the legs elongate. 
In the female the last ventral segment is depressed and divided in the middle, and to each side of the division is 
attached a small process, which looks at first sight like a thickening of the edge; anal process large and 
long, broader towards the base than towards the apex, which is truncate. 
Long. cum tegm. 11 millim.; lat. ad hum. 5 millim.

This is a very distinct species, and it ought perhaps to be separated from the genus 
Thionia, but on account of the simple interior ulnar vein and the bispinose tibie it may 
be provisionally placed here. There are also in our collection two obscurely coloured 
specimens, from Senahu and San Juan in Vera Paz, of a closely allied form with the 
vertex very narrow and its sides auriculate, but I prefer not to describe them. 
11. Thionia soluta, sp. n. (Tab. XII. figg. 25, 25a.) 
Sat lata, convexa, viridescenti-testacea; capite brevi, pronoto angustiori ; vertice angusto, latitudine fere longiori, 
lateribus elevatis subauriculatis, fronte longa, angusta, verticem versus sensim angustaté, carina centrali 
in clypeo continuata, fortiter elevaté; pronoto modico; scutello ad medium leviter canaliculato ; 
tegminibus amplis, convexis, lateribus ad medium sensim rotundato-angulatis, confusius venatis, plus 
minusve reticulatis ; alis amplis, flavescentibus ; corpore subtus pedibusque testaceis. 
Femina processu anali longo, antice sensim angustato, apice truncato, segmento ultimo ventrali simplici. 
A rather broad and convex species, of a greenish-testaceous colour, which is probably much more distinct in 
life; head short, narrower than the pronotum; vertex narrow, longer than broad, the sides elevated 
and auriculate; forehead long, narrow, very gradually narrowed towards the vertex, with a strong central 
keel, which is continued on the clypeus; pronotum with two distinct impressions in the middle; 
scutellum with a fine central channel; tegmina rather broad, with the sides very obtusely and roundly 
angled at the middle, somewhat confusedly veined, and more or less reticulate ; wings large, of a bright 
yellowish colour; legs testaceous, with the tarsal claws fuscous. 
Female with the last ventral segment simple, and the anal process long, gradually narrowed to the apex, and 
truncate. 
Long. cum tegm. 8 millim.; lat. ad hum. 4 millim. 
Hab. PanaMa, Bugaba (Champion). 
One of our two specimens has the interior ulnar vein of the tegmina simple and the 
tibise regularly bispinose, but the other has this vein roughly furcate; this latter 
example, however, is evidently abnormal, as one of the posterior tibie has the spine 
before the apex wanting. It is the only individual I have seen amongst the species 
with notched and folded wings in which the tibie are bispinose and the interior ulnar 
vein forked; the furcation may be an effect of the irregular venation.
