640 L. Bruner: 
Abisares viridipennis (Burmeister?) 
The collection contains several specimens of both sexes of a locust that I am inclined to refer to 
Burmeister’s Monachidium viridipenne. "They were taken during April and May, 1903, on the Island of 
Pemba (British East Africa). Some are dried but others are preserved in alcohol. 
Burmeister’s two line description is scarcely sufficient for one to determine the insect by. The 
general appearance of these locusts would suggest Dericorys or a close relationship with that genus, but 
the absence of a terminal spine on the outer edge of the hind tibiae places it elsewhere. 
Bibracte(?) malagassa n. sp. Fig. 15. 
Brunneo-testaceous varied on face, sides of pronotum, tegmina, pleura, abdomen and legs with dark 
brown, piceous and black bands, patches and spots. Size below the medium, tegmina greatly abbreviated, 
lateral. Hind femora somewhat slender and elongate. 
Head a little narrower than the anterior edge of the pronotum (9) or somewhat wider (3), the 
oceiput short and provided with a well defined median carina, embraced by the pronotum nearly to the 
prominent eyes; vertex as wide as the frontal costa at its broadest part, deeply sulcate and bounded by 
strong carinae; the fastigium gently depressed, about as broad as long, the sulcation quadrate, separated 
from the suleus of the frontal costa by the meeting of its bounding walls; frontal costa fairly prominent, 
the walls heavy and nearly parallel save immediately below the ocellus where they bow inwards and 
again outwards to continue their general course to the clypeus, deeply sulcate; front somewhat rugose, 
the facial carinae prominent, divergent. Antennae filiform, about as long as the head and pronotum together, 
fasciate. Pronotum above rugose, provided with well defined but interrupted lateral and a strong median 
carinae, the anterior lobe twice the length of the posterior, lateral lobes about as high as long, the lower 
posterior portion broadly rounded and the middle provided with an obliquely upward and posteriorly 
directed ridge above which are located two large, smooth patches or depressions; anterior edge straight 
or nearly so, the hind margin widely and angulately emarginate at middle. Abdomen short, strongly 
carinated, the valves of the ovipositor long and coarse, exserted; tip of the male abdomen slender, short, 
the last ventral segment roundly acuminate, provided at middle with a faint longitudinal carina; supra- 
anal plate triangular, longitudinally sulcate at middle on basal half; cerci moderately heavy, pyramidal, 
shorter than the plate. Tegmina lateral, spatulate, reaching just past the apex of the first abdominal seg- 
ment. Hind femora moderately slender, surpassing the tip of the abdomen in both sexes, plainly serrated 
on the superior carina, the genicular lobes rounded, hind tibiae rather coarse and somewhat undulate, 
provided with seven spines externally and nine internally, the spines fairly long and coarse. Prosternal 
spine coarse, transverse, and in the female faintly emarginate at middle of apex. Interspace between the 
mesosternal lobes a little less than the width of the lobes themselves. 
The front, cheeks, lower third of sides of pronotum, legs and under side chiefly testaceous, above 
wood-brown varied with darker markings. Antennal socket black, sides of head back of eyes and upper 
two-thirds of lateral lobes of pronotum together with the upper portion of pleura piceous, costal area of 
tegmina glossy black, occiput, dorsum of thorax and basal half of abdomen varied with paler along the 
rugae while in the depressions the background is darker. Hind femora mostly testaceous (8) or strongly 
infuscated, save for a conspicuous, large, oblique, testaceous patch on the outer face and upper 
edge; tibiae inclining to rufous; anterior and middle legs mottled with fuscous, the tibiae and antennae 
annulated.
