830 Mr. M. Jacoby^s contributions to the knowledge of 
the Cape Town Miiseuiii_, and another received from Dr. 
Kraatz without particular locality; both specimens agree 
in every particular. The species is evidently closely allied 
to M. flavomarginatay Jac, also from Africa, but differs 
in the entirely black antennae and tibiae; also in the 
absence of the bluish tint of the elytra. 
Malacosoma hasimarginata, sp. n. 
Fulvous, thorax subquadrate, irapunctate, elytra closely and 
distinctly punctured and slightly rugose, the basal margin and the 
suture anteriorly greenish-black. Length, If lines. 
Head impunctate, the frontal tubercles elongate, joining the 
clypeus in front, carina absent ; antennae extending to the middle 
of the elytra, rather robust, fulvous, the terminal joints often 
fuscous, third joint one-half longer than the second, but shorter 
than the fourth ; thorax subquadrate, one-half broader than long, 
the sides nearly straight, the angles not prominent, the base with 
a narrow but distinct margin, the surface rather convex, impunc- 
tate, pale fulvous ; scutellum fulvous or nearly black ; elytra 
parallel, rather closely and distinctly punctured, the interstices 
somewhat wrinkled, the basal margin greenish-black, this colour 
extending also a little distance downwards at the shoulders and 
the suture, but variable in extent, and sometimes only indicated at 
the suture ; legs rather robust, all the tibiaa with a minute spine, 
the first joint of the posterior tarsi as long as the following joints 
together ; claws appendiculate, anterior cotyloid cavities open ; 
prosternum very narrow, convex. 
Hah, Zanzibar. 
The underside in one specimen is piceous. 
Malacosoma suturalisj sp. n. 
Fulvous, the terminal joints of the antenna and the breast 
black, thorax impunctate, broader than long, elytra very finely 
punctured, a sutural band widened posteriorly, piceous. Length, 
lines. 
Head piceous at the vertex, impunctate, frontal elevations 
broad, transverse, carina acutely raised ; antennas scarcely extending 
to the middle of the elytra, fulvous, the third and fourth joints 
equal, the following joints slightly shorter and thickened ; thorax 
one-half broader than long, rather convex, the sides rounded and 
rather suddenly widened at the middle, narrowed at base and 
apex, rather strongly deflexed anteriorly, the angles not produced ; 
surface convex, very closely impressed with very minute punctures.
