334 Mr. M. Jacoby's contributions to the knowledge of 
near the scutellum, another elongate spot below the middle 
gradually narrowed to half its size near the lateral margin and 
the apex of each elytron, black ; breast and legs more or less 
piceous, abdomen obscurely testaceous ; prosternum naiTow but 
distinct and convex, metatarsus of the posterior legs longer than 
the following joints together. 
Hah. Mashunaland, Salisbury. 
The single specimen before me differs in the dis- 
tinct and convex, although very narrow, prosternum, 
resembling in that respect Malacosoma. I have, however, 
thought best to leave it at present in Sermyla, 
Sermyla (Malacosoma) sutiiralis, Alld. 
Black, the basal joints of the antennae and the upper surface 
fulvous, head and thorax impunctate, elytra extremely finely and 
closely punctured, the extreme sutural margin and the scutellum 
black. Length, 3-4 lines. 
Of elongate and convex shape, the head impunctate, fulvous, 
the frontal tubercles scarcely marked, slightly more distinct in 
the female, clypeus broad and also ill-defined ; antennae not ex- 
tending to the middle of the elytra, black, the lower three joints 
fulvous, the second joint one-half the length of the third, this one 
shorter than the fourth joint ; thorax twice as broad as long, the 
anterior margin straight, the sides rounded as well as the posterior 
margin, the anterior angles not produced, slightly thickened ; the 
surface entirely impunctate, fulvous ; scutellum black ; elytra con- 
vex, not covering the pygidium, extremely closely and finely 
punctured, the suture very narrowly edged with black ; underside 
black, the legs fulvous (the femora sometimes black), all the tibiae 
mucronate, the first joint of the posterior tarsi longer than the 
following joints together, claws appendiculate, anterior coxal 
cavities closed. 
Hah, Hex Kiver, Africa ; also Cape. 
This species, of which I have given here a renewed 
description, has been placed by M. Allard in Malacosoma, 
where it cannot remain on account of the closed anterior 
cotyloid cavities. I have been enabled to examine a 
typical specimen, kindly given to me by M. Severin. 
Three others I received from Mr, Peringuey.
