FLATOIDES. 63 
II. Posterior tibizee with two distinct spines towards the apex. 
8. Flatoides griseus, sp. n. 
Griseus ; capite brevi, transverso, antice truncato, macula parva nigra, minutdque alter4 utrinque instructo, 
‘oculis prominulis; pronoto sat longo, notis nigris minutis, antice rotundato, haud emarginato; scutello 
brevi, longitudine latiori ; tegminibus latis, haud decumbentibus, margine costali dense, margine apicali 
rarius transversim regulariter venatis, vitté angusta, fuscé, ante apicem fortiter sinuataé; tibiis posticis 
bispinosis. 
Femina. Lamina apicali abdominis haud transversé, maxima. 
Of a greyish colour, with more or less obscure fuscous markings, mostly insignificant ; head short, transverse, 
truncate, with a small black spot just at the front edge of the vertex and a black dot on each side: 
pronotum comparatively long, rounded in front, dotted with black; scutellum broader than long; 
tegmina large, not decumbent, broadest just behind the shoulders, with a strongly marked sinuate fuscous 
band before the apex, and the humeral calli partly surrounded with dark colour; costal margin thickly 
and regularly set with transverse nervures, which are much less close at the apex ; posterior tibie with 
two large spines towards the apex. 
Female with the apical plate of the last abdominal segment very large. 
Long. 13 millim.; lat. ad hum. 8 millim. 
Hab. Guatemaua, Mirandilla 1700 feet (Champion). 
This species very closely resembles J’. simallimus, from which, however, it differs in 
having bispinose tibie, a character which, according to Stal, places it at once in a 
separate genus. 
There are two specimens in our collection with the posterior tibize bispinose—one 
from Jalapa, Mexico (Hdge), and the other from Duefias, Guatemala (Champion), which 
I thought at first might be referred to F. griseus; they are, however, plainly different, 
and probably belong to quite distinct species; they are scarcely in a condition to 
describe on single examples. 
9. Flatoides isabellinus, sp.n. (Tab. VIII. figg. 5, 5 a.) 
Griseus, isabellinus; capite brevissimo, triangulariter producto, oculis prominulis; pronoto capite fere longiori, 
antice rotundato; scutello latitudine longiori; tegminibus pane unicoloribus, margine costali dense, 
margine apicali crasse et rarius transversim venosis ; alis plus ninusve infuscatis ; tibiis posticis distincte 
et sat fortiter bispinosis. 
Of a greyish dun-colour; head very short, in the form of a broad-based triangle; pronotum almost longer 
than the head, rounded in front; scutellum longer than broad ; tegmina nearly unicolorous, a little lighter 
in parts, with some scattered minute fuscous dots, and with or without a somewhat indistinct fuscous band 
before the apex ; costal margin with thickly set and rather indistinct transverse veins, those on the apical 
margin being coarse and very distinct and more widely separated ; wings smoky ; posterior tibie bispinose. 
Female with a moderate-sized laminal abdominal plate at the apical segment of the abdomen. 
Long. 11-18 millim.; lat. ad hum. 5-8 millim. 
Hab. Panama, Caldera, Volcan de Chiriqui (Champion).
