Thespis metae new species (Plate IX, figure 23.) 
Tliis species apparently shows nearest affinity to T. media 
(Giglio-Tos),^^ the male here described differing in its slightly 
smaller size, slightly deeper head, broader and more strikingly 
marked tegniina, proportionately more elongate tegmina and 
wings, of which the latter reach to the base of the supra-anal 
plate, very slightly shorter supra-anal plate and other less con- 
spicuous features. 
Type . — cf , Mllavicencio, Intendencia del Meta, Colomlha. 
Elevation, 1400 feet. October, 1919. (From A. Maria.) [Heb- 
ard C'ollection, Type no. 724.] 
.Size niediuin large coinjiared with related species, small for the genus; 
form slentler. Head with greatest dei)th three-fiuarters of greatest width; 
occipital outline in portion of occiput between eyes and the decided juxta- 
ocular sulci strongly convex, these portions raised above the eyes, the inter- 
vening median j)ortion of the occiput as high mesad and slightly higher 
laterad, its dorsal outline weakly convex laterad and mesad, weakly concave 
meso-laterad on each side. Lateral ocelli slightly larger than median ocellus, 
the triangle which they form three-fifths as deei> as wide. PAcial scutellum 
very strongly transverse, about four times as wide as its median depth, its 
dorsal margin broadly convex, this margin rounded and not sharjdy defined. 
Pronotum very elongate, its greatest width contained about four times in 
length of shaft; shaft with margins subparallel, scarcely narrowing to the 
suiira-coxal exjiansion, the latter moderate, forming rounded obtuse-angula- 
tions, the collar narrower than shaft with margins nearly parallel beyond 
convergence caused by supra-coxal expansion. Lateral margins of pronotum 
minutely denticulate, the denticulations finer than in media, shaft with a 
distinct and rather decided medio-longitudinal carina, this carina very fine, 
subobsolete, on the collar; collar with rounded lateral carinae, the surface 
delicately concave above and below these. 
Tegmina elongate, failing to reach apices of wings by a brief distance; 
broad, decidedly broader than in media, a])ex rather broadly rounded; mar- 
ginal field thickly and minutely areolate, discoidal and anal fields with false 
veinlets between the veins, which with the cross-veinlets form large irregu- 
lar areolae. Tegmina and wings microscopically very finely pilose, this 
coarser on the costal margins. 
.Supra-anal plate elongate triangular, length twice basal width, apex acute, 
dorsal surface with a very delicate medio-longitudinal carina. Cerci elon- 
gate, flattened, very hairy, the joints increasing in length distad, the distal 
joint bluntly rounded and over three times as long as its proximal width. 
Our comparison is made, with the brief original description, of a male from 
Trinidad, and a male from Caparo, Trinidad, taken in Augmst, 1913, by S. IM. 
Klages, in the Hebard Collection.
