yellowish pubescence, the disc entirely piceous, the margins 
narrowly fulvous; scutellum obscure fulvous, its apex truncate; 
elytra closely punctured, the interstices finely transversely 
wrinkled and sparingly clothed with yellow short pubescence; 
underside more densely pubescent; the base of the femora more 
or less fulvous, the tibiae and tarsi fuscous; claws bifid; an- 
terior coxal cavities open. 
Scioa, Let-Marefia (0. Antinori). 
This species resembles P. clavicornis Karsch in the short apical 
joints of the antennae, but differs in the angulate not rounded 
sides of the thorax and the coloration. 
6. Megalognatha abyssinica, n. sp. 
Elongate black; head impunctate; thorax square-shaped , 
closely and finely punctured; elytra very closely and finely 
punctured and wrinkled, longitudinally depressed at the sides. 
Length 4-4 1/, lines. 
Q. Head impunctate; the frontal tubercles trigonate, divided 
by a fine groove; antennae black, half the length of the body, 
the third to the seventh joints equal, the following ones shorter; 
thorax squareshaped, the surface closely and finely punctured, 
the middle of the disc, with some rugosities, more or less di- 
stinct; elytra more closely punctured than the thorax, the 
interstices very finely. wrinkled, the sides with a longitudinal 
sulcation not extending either to the base or apices; below and 
the legs black, the abdominal segments narrowly edged with 
fulvous ; pygidium black. 
Scioa, Cialalaka Lake (O. Antinori). 
I have evidently only female specimens of this species before 
me, and it is probable that the male insect is furnished, like 
the allied species with deep excavations at the thorax; M. abys- 
sinica seems closely allied to M. rufiventris Baly but differs in 
being lar&er and entirely of black colour, the sides of the 
thorax are also less constricted behind and nearly straight.
