African Phytophagous Coleoptera. 327 
described, the other being an inhabitant of Abyssinia. 
It is possible that some specimens may occur in which 
the elytral black bands unite more or less, so as to leave 
six flavous spots of the ground-colour. In the specimen 
before me this is partly the case ; the apical band only is 
isolated, although curving round at the apex and being 
joined to the suture ; the first band extends upwards at 
the shoulder to the base, and joins the second band at 
its middle. 
GALERUCIN^. 
Asbecesta pectoralis, sp. n. 
Black, the first three joints of the antennas, the head, thorax, 
and legs fulvous ; elytra metallic-blue, very closely and strongly 
punctured, the interstices slightly rugose. Length, 2 lines. 
Head impunctate, reddish-fulvous, labrum and palpi black ; 
antennae not extending to the middle of the elytra, black, the basal 
three joints fulvous, third and fourth joints equal ; thorax twice as 
broad as long, fulvous, the basal sulcus deep, slightly sinuate, 
more or less distinctly punctured as well as the anterior portion at 
the sides ; scutellum black ; elytra deeply and closely punctured, 
the interstices scarcely larger than the punctures ; breast and 
abdomen, as well as the tarsi, black.

A. pedoralis is very closely allied to A. ahdominalis, 
Jac, from Togo (Bismarksburg), but differi3 in having 
only the three lower joints of the antenn83 fulvous, the 
thorax more distinctly punctured, and the elytral punc- 
tuation deeper and more closely placed, as well as in the 
black scutellum and breast ; in the female the elytral 
punctuation is still coarser, and a distinct longitudinal 
sulcus is seen at the sides of the elytra,. In A. ahdo- 
minalis, the black abdomen has a distinct metallic-blue 
lustre which in this species is absent. 
Asbecesta melanocephala, sp. n. 
Black, the lower four -joints of the antennae, the thorax and 
legs flavous ; elytra metallic greenish-blue, deeply and closely 
punctured, tarsi black. Length, 2 lines.
