Porrucuese EH. Arrica: Beira (P. A. Sheppard). 
This species probably represents on the coast the very 
closely allied P. kirschi, Fst., which at present is known only 
from Nyasaland. The latter differs in having the sides 
of the prothorax simply rounded and not denticulate, the 
lateral areas of the rostrum are not impressed, the sete on 
the elytra are distinctly longer and more slender, and the 
scales on the elytra are for the most part rather sharply 
pointed behind instead of being broadly rounded.

Genus BrapyBaMon, nov. 
Head with a short central furrow and slightly raised at 
the sides to form an obtuse eyebrow, which is higher behind 
than in front ; eyes quite lateral, nearly circular, “moderately 
prominent, and’ not produced backwards. Rostrum sub- 
quadrate, separated from the forehead by a deep sinuous 
furrow that distinctly reaches the sides, lower surface 
flattened or slightly concave ; epistome forming a sharp 
acute angle behind, the bounding carne unusually lugh 
and finely laminate, the front margin rather shorter than 
the sides ; mandibles multisetose, not squamose, with a 
median tooth, the scar flat and almost circular; mentum 
bare, somewhat sunk ineits cavity ; genze deeply impressed, 
the posterior angle rather prominent. Antenne with the 
scape abruptly clavate and reaching about the middle of the 
eye; funicle squamose, joint 1 equal to or longer than 2, 
the others short, 7 the broadest. Scutedlum invisible. Elytra 
with the sides forming a straight slope from the base to 
the well-marked Ghenaneee prominence, the basal margin 
sinuate ; in profile, the outline of the posterior declivity 
forms almost a semicircle, the apex being inflexed so that 
it lies in front of the middle of the declivity. Sternum 
with the gular margin gently sinuate, the ceutro-sternite 
forming an elongate tubercle ; mesepisternum meeting or 
or very “narrowly separated from the elytra ; metasternum 
much shorter than the mid- -coxee, with a distinct antecoxal 
fold, the episternal furrow deep and complete, the episternum 
narrow and not angulate inwardly at the base, the hind 
coxe separated from the elytra. Venter with the intercoxal 
process gently rounded and as broad as the coxa; the hind 
margin of segment 1 curved, so that segment 2 is much
