We have received a single specimen from Cerro Zunil which appears to belong to 
D. brevis, Fairm.; this insect is shorter and has a somewhat blunter apex to the 
pronotum than S. acutula, but they cannot well be separated. We figure an example 
of S. acutula from Chiacam. 
N.B.—I have before me Signoret’s type of Darnis prasina (from Venezuela), on which 
Fairmaire described the species; it is very like Cryptoptera olivacea, Stal (=Darnis 
olivacea, Fabr.), and perhaps ought to be referred to that species. 
TROPIDARNIS, gen. nov. 
Generibus precedentibus affinis, sed dorso elevato, distincte et acute carinato facillime distinguendus; tegmi- 
nibus tertié parte intectaé, vix ad apicem pronoti extensis, ad basin externe opacis et fortiter punctatis, 
corio tribus venis e basi emissis et areis discoidalibus duabus, interiore apicem versus dilatato ; pedibus 
teretioribus. 
Allied to the other genera of the family, but easily distinguished by having the back 
of the pronotum raised and acutely keeled; the tegmina scarcely reach the apex of the 
pronotum, and have about one-third of their breadth exposed beyond its sides; the base 
externally is opaque and strongly punctured ; three veins proceed trom the base of the 
corium, and are continued to the apex, as in Darnis, Leptosticta, and Hebeticoides; and 
there are two discoidal areas, of which the interior is the longest and is dilated at the 
apex, the exterior one starting at the dilated portion and continuing towards the apex ; 
the legs are rather slender. In the specimen described there is an oblique depression 
on each side of the dorsal keel at about the middle, which meet or almost meet at the 
keel and form a very indistinct V-shaped mark. 
1. Tropidarnis tectigera, sp.n. (Tab. V. figg. 7, 7 a-c.) 
Virescens, capite testaceo; pronoto antice sat lato, humeris modice prominulis, ad apicem acutum sensim 
angustato, distincte et regulariter punctato, vix nitido, dorso elevato, a latere viso sequaliter declivi, carina 
sat nitida instructo; tegminibus hyalinis, vitté longitudinali exteriori brunned; pedibus et corpore subtus 
fusco-testaceis. a . 
Of a light greenish colour, with the head and the metopidium just above the. head testaceous; pronotum, 
viewed from above, rather broad in front, with the sides slightly rounded and gradually narrowed to the 
apex, which is acute, and with a distinct shining keel, which is continued as a smooth line on the meto-
