128 HEMIPTERA-HETEROPTERA. 
Three males and two females. In this insect the elytra are slightly mottled with 
pale brown, and the antenne are a little shorter and stouter than in the other species 
here described. It is relatively more elongate than the winged form of MV. circwm- 
cincta. Our figure is taken from the specimen in the Brussels Museum. 
3. Microvelia panamensis, n. sp. (‘T'ab. VIII. fig. 14, winged ¢ .) 
Winged form. 3. Short, much narrowed behind; black, the basal margin of the head obscure fulvous, the 
pronotum with a narrow transverse band in front, the posterior margin (except in the centre), and the 
lateral margins beneath, the venter along the middle and at the apex, the connexivum (the sutures 
excepted), the trochanters, coxa, and rostrum, flavous ; the legs brownish, with the extreme base of the 
femora flavous; the antenne fuscous; the elytra blackish-brown, with greyish streaks, the nervures 
darker; the under surface and pleura with a bluish-grey pruinosity, and slothed with short, fine, 
scattered silvery pubescence ; the upper surface very finely pubescent, the pronotum with a few silvery 
hairs on the lateral portions of the anterior lobe and at the sides posteriorly ; the antenne: and legs 
finely pubescent. Head with a smooth, fine, impressed median line; antenne long and very slender, 
nearly as long as the body, joints 1 and 2 subequal in length, 3 much longer than 2, 3 and + nearly 
equal in length. Pronotum obtuse at the apex behind, with indications of a median ridge anteriorly. 
Elytra with prominent nervures. Legs slender, long, the femora slightly thickened towards the base. 
6. Posterior femora armed with four or five very minute projecting teeth. 
Apterous form. 9. Short, fusiform, the disc of the pro- and mesonotum, and the terminal dorsal segments of 
the abdomen, obscure ferruginous ; the upper surface with scattered silvery hairs, the apical half of the 
abdomen bordered with silvery hairs at the sides, the penultimate dorsal, and the second, fourth, and 
fifth connexival segments almost covered with silvery hairs. 
Length 24, breadth 1 millim. 
Hab. Panama, David, Volcan de Chiriqui ( Champion) 
A winged pair from David and an apterous female from the Volcan de Chiriqui. 
Allied to M. torquata, but with much stronger nervures to the elytra, the elytra 
without distinct spots, the pronotum with a few silvery hairs only at the sides in front, 
the legs darker, the posterior femora in the male armed with several minute projecting 
teeth. 
4. Microvelia torquata, n.sp. (Tab. VIII. fig. 15, winged ¢ .) 
Winged form. Rather short, narrowing behind, black, the anterior and posterior margins of the pronotum, 
as well as the lateral margins beneath, the connexival margins, the coxe, and trochanters flavous; the 
under surface flavous, with a blackish submarginal stripe on each side of the venter, extending on to the 
pleura; the antenne brown, paler at the base in one specimen; the legs flavous, the femora with 
indications of a brownish transverse band towards the apex, the tibie broadly brownish in the middle, 
and the tarsi slightly infuscate; the elytra brownish-black, with six oblong whitish streaks ; the body 
clothed with very short, fine, yellowish pubescence, a narrow space across the front of the pronotum, and 
the meso- and metapleura, clothed with glistening silvery pubescence; the antenne and legs sparsely and 
very finely pubescent. Head with a fine, smooth, impressed median line ; antenne very slender, nearly 
as long as the body, joints 1 and 2 subequal in length, 3 rather more than one-half longer than 2, 
3 and 4 equal in length. Pronotum obtuse at the apex behind, without trace of median ridge. LElytra 
with rather feeble nervures. Legs slender, moderately long, the femora slightly thickened towards the 
base, the anterior pair strongly swollen in their basal half in the male. 
Length 24-23, breadth ,%-1 millim. (¢ 2.)
