the male holotype are narrow and straplike, extending slightly beyond the middle of the second abdominal segment: on the female allotype the hemelytra are large and long, extending to the middle of the fifth abdominal segment. C o x a e : The distance between the first and second coxae is to that between the second and third coxae as 30:58 (holotype), 40:70 (allotype); on the right sidc of the body of the maie holotype the anterior acetabulum has two pits anterior to the cleft and two pits posterior to it; the middle acetabulum has lour faint pits similarly arranged; the posterior acetabulum is unpitted. F e m o r a : The anterior femora of the male holotype do not extend quite to the apex of the head while on the female allotype the anterior femora reach slightly beyond the apex; the posterior femora slightly surpass the tip of the abdomen on both the holotype and allotype. Abdomen: Length. 154 units (holotype); the two male processes, located on the ventral side of the sixth segment, are placed so that each one is about midway between both the anterior and posterior ends of the segment and the median longitudinal line and the lateral margin: the processes are small tufts of very stiff hairs: posterior to each of the processes and located on the margin of the segment, is a brush of long stiff hairs; the posterior margin of the sixth segment has a fringe of short stiff hairs on the dorsal side: the seventh segment of the holotype is somewhat compressed ventrolaterally to form a broad, median, ventral, longitudinal keel which is broadly expanded distally; on each side of the keel is a large depression; the terminal dorsal process of the holotype is long and stout, about one-third the length of the segment; the terminal dorsal process of the allotype is long and sharp, about one-half the length of the segment. Described from three males and four females collected in Madagascar by CH. ALLUAUD. The malc holotype and two paratypes (onc male and one female) were collected in the „Region du Sud-est" in 1901; the female allotype and two paratypes (one male and one female) were collected in Diego-Suarez in 1893; the other femalc paratype was taken in the ,.Region du Sud" in 1901. Types in the Paris Museum. N o t e s. The bifurcated condition of the clypeus and the nature and position of the male processes distinguish this species from all other known species.
