Coleoptera from Africa and Madagascar. ot 
of a basal depression, and are convex and_ sub- 
cylindrical. In all the allied species the elytra have 
ten rows of deep and for the most part regularly-placed 
punctures. Their epipleure in the present species are 
eh obscure piceous, as is also the extreme base of the 
lorax. 
Lema apicicornis, n. 8. 
Black; the head, the basal and two apical joints of the antenne, 
and the thorax, fulvous; elytra metallic-blue, deeply depressed 
below the base; abdomen fulvous. Length, 23 lines. 
Head impunctate, without frontal elevations; eyes very large, 
but slightly notched; clypeus black at its lower portion ; antenn 
half the length of the body, black, the two basal and the two 
apical joints fulvous; thorax about as broad as long, rather deeply 
constricted at the middle, the anterior angles slightly tuberculi- 
form, the basal suleation deep and placed at some distance from 
the basal margin, the surface without punctures; scutellum ful- 
vous ; elytra with the basal portion strongly raised and bounded 
behind by an oblique depression extending from within the 
shoulders to the suture, the punctuation strong anteriorly, 
gradually diminishing towards the apices, the interstices nearly 
flat, the ninth stria not interrupted at the middle, the lateral 
margin with a deep longitudinal depression below the shoulders,

Hab. Old Calabar. A single specimen in my col- 
lection. 
Allied to ZL. rubricollis, Klug, but differing in the 
colour of the head and that of the antenne. 
Lema laticollis, n.s. (Pl. VII., fig. 1).

(1, 2, 1, 1, 1); legs fulvous, spotted with black. Length, 2 lines. 
Head sparingly clothed with very short golden hairs, the vertex 
black, spotted with fulvous at the sides and at the middle, the 
latter divided by a deep longitudinal groove, the frontal elevations 
absent; eyes deeply notched, with the usual grooves near their 
inner margins, lower part of the face fulvous; labrum black ; 
antennz short and very robust, the four lower joints very small, 
transverse, the following joints equal, broader than long, opaque,
