Euprepocnemis brachypterus n. sp. Fig. 17. 
A medium sized insect with abbreviated tegmina and wings and in which the apical third of the 
hind tibiae are carmine and the basal portion plumbeous. 
Head moderately large, a trifle broader than the anterior edge of the pronotum; the front viewed 
laterally oblique, arcuate; eyes not prominent, of moderate size, evenly rounded behind, straight or nearly 
so in front, separated above by a space a little greater than the widest part of the prominent frontal 
costa; vertex gently depressed, sulcate and provided at middle with a strong median carina; frontal costa 
prominent, in nowise sulcate, slightly widening below, marked near each carina with a row of small regularly 
arranged punctures. Antennae filiform, about as long as the head and pronotum together (9) or a trifle 
longer (3). Pronotum short, the sides of the anterior lobe gently arcuate outwardly when viewed from 
above, the posterior lobe a little more than one-half as long as the anterior and divergent posteriorly; 
lateral carinae somewhat obliterated on the hind lobe, rather prominent on the front lobe, median carina 
fairly prominent throughout, anterior edge slightly emarginate, posterior edge truncate (9) or subangulate (8). 
Tegmina abbreviated, acuminate, only two-fifths (9) to three-fourths (3) the length of the abdomen, their 
costal margin gently arcuate, the posterior edges not quite touching on the basal fourth but gently over- 
lapping beyond. Hind femora moderately robust, evenly tapering apically, in the females about reaching, 
in the males considerably surpassing the apex of the abdomen. Apex of male abdomen pyramidal; cerci 
slender, acuminate, gently bowed inward, their tips surpassing the supra-anal plate; the latter a little longer 
than wide, the sides rounded and provided with a heavy and elevated carina which reaches nearly to the 
tip, middle elevated and provided on basal third with a pair of ridges which unite at their outer ends so 
as to form a small >-shaped sulcus. Prosternal spine coarse, the apex broadly rounded and directed to 
the rear so as to nearly or quite touch the front edge of the mesosternum. Hind tibiae 11- or 12-spined 
on their outer edge. 
General color brunneo-testaceous, the middle of sides of pronotum in advance of hind sulcus 
piceous marked in both sexes with a dirty white patch; disk above largely dark brown, this colored area 
narrowing on the hind lobe. Tegmina with the discal area darkest and showing traces of maculation by the 
presence of a few small pallid spots, there is also a well defined subcostal pallid streak that extends two- 
thirds the length of the wing. Hind femora with an obscure line along upper edge of outer and inner 
disks, the lunules and a blotch in advance of the lobes black or piceous; the spines dirty white with their 
tips black. 
Length of body, 3, 19 mm, 9, 33 mm; of pronotum, d, 4,35 mm, 9, 5,4 mm; of tegmina, d, 9 mm, 
9, 13 mm; of hind femora, d, 14 mm, 9, 20 mm. 
Habitat: Central Madagascar, one female; Alaotra Lake (E. Madagascar) one male and several 
females. 
Euprepocnemis smaragdipes n. sp. 
Very similar in size to the preceding or a little larger, but with fully developed tegmina and 
wings and with uniformly-dirty greenish gray hind tibiae. Disk of pronotum and oceiput longitudinally 
broadly fasciate with brown. The lateral lobes scarcely varied with piceous. General color brunneo- 
testaceous. The disk of tegmina mottled with brown and showing several pallid spots on the basal half 
where the veinlets are conspicuously pallid. Fastigium gently sulcate and provided with a rather strong 
longitudinal carina that reaches the middle of the oceiput. Eyes moderately large and somewhat prominent, 
considerably longer than the cheeks below them, their anterior edge nearly straight, marked by a number
