130 HEMIPTERA-HETEROPTERA. 
Hab. GuateMa.a, Duefias (Champion). 
One specimen only of this handsome little species was obtained. It approaches 
M. modesta, Uhler, from the Island of Grenada, but has shorter legs. The elytra are 
somewhat immature and creased, but they appear to have each five silvery-white spots 
or streaks. The head is without an impressed median line. 
M. mimula, Buch. White, from the Amazons, and J. signata, Uhler, from Lower 
California, are also allied forms. 
7. Microvelia rufescens, n. sp. (Tab. VIII. fig. 18, apterous specimen.) 
Apterous form. Obovate, rather narrow, convex beneath; fuscous of fusco-ferruginous, the pleura and sides 
of the venter blackish, the connexivum above and beneath obscure ferruginous; the antenne, coxe, 
trochanters, and legs testaceous or flavo-testaceous; the upper surface thickly and uniformly clothed with 
brownish pubescence ; the under surface greyish-pruinose and clothed with pallid pubescence; the legs 
and antenne very finely pubescent. Head with indications of a very fine impressed median line in front ; 
antenn more than half the length of the body, slender, joint 2 shorter than 1, 3 very slender and nearly 
twice as long as 2, 4 slightly longer than 3, pointed at the tip. Legs moderately long, comparatively 
stout, the tibiz included. 
Length 23-23, breadth (of the abdomen) 1-13 millim. 
Hab. GuateMALA, Duefias (Champion). 
Three specimens, apparently two males and one female. ‘The supposed female is 
more convex than the others, and has the short genital segments not visible from 
beneath. In the males(?) the genital segments are narrowly exposed above and 
beneath. This insect has stouter tibie than any of the other Microvelie here described, 
and the body is obovate, instead of fusiform, the species approaching in this respect the 
European M. pygmea (Duf.). 
8. Microvelia setipes, n.sp. (Tab. VIII. fig. 19, apterous ¢.) 
Apterous form. ¢. Elongate, narrow, narrowing in front and behind, black or blackish-fuscous, the pronotum 
with a transverse rufo-fulvous band in front; the connexivum, the pleura, the middle of the meso- and 
metanotum and also of the dorsal segments of the abdomen, and the venter, except at the sides, obscure 
ferruginous; the rostrum flavous, with the apical joint black; the coxe and trochanters flavous; the legs 
brownish, with the femora flavous or testaceous; the antennee fuscous, with the base of the first joint 
testaceous ; the under surface and pleura with a bluish-grey pruinosity; the body, legs, and antenne 
finely pubescent, the sides of the metanotum and the dorsal surface of the abdomen with a good deal of 
silvery pubescence, the silvery hairs on the first three dorsal segments formiug a large patch, the posterior 
tibize with a row of long bristly hairs on their outer edge. Head with a smooth impressed median line; 
antenne about half the length of the body, joints 1 and 2 subequal in length, 3 and 4 each much more 
elongate, subequal in length, 4 rather stout and fusiform. Legs long, the femora rather stout. Sixth 
ventral segment feebly arcuate-emarginate at the apex. 
Apterous form. 9. Elongate-obovate, flattened above, the venter very convex ; the dorsal abdominal segments 
very little wider than the connexival segments, the latter sloping downwards externally. 
Length 23-3; breadth, ¢ 7, 9 1j millim. 
Hab. Mexico, Chapultepec and Orizaba (Bilimek, in Mus. Vind. Ces.). 
Three males and a single gravid female, evidently belonging to the same species. 
Differs from all the other Central-American species described here in the setose posterior 
tibize, a character common to WM. longipes, Uhler, and other Antillean forms.
