REDESCRIPTIONS 
OF SOME 
NEW SPECIES OF PHYTOPHAGOUS COLEOPTERA 
FROM MADAGASCAR 
Collected by E. and B. PERROT in the collection of R. OBERTHÜR 
by Martin Jacoby. 
Pœcilomorpha flabellicornisJacoby (Novit. Coleopt.1895, p. 1). 
Black, opaque, pubescent, terminal joints of the antennœæ flabellate, 
head finely rugose-punctate, thorax angulate at the sides, elytra clo- 
sely pubescent with two narrow undulate transverse bands at the 
middle and a spot at the apex, formed of grey pubescence, legs and 
underside clothed with black and grey pubescence. 
Length : 4-7 lines. 
Of broad and nearly parallel shape, entirely black, the pubescence 
black and grey, the head finely rugose-punctate throughout, spa- 
ringly clothed with short grey hairs, eyes large, moderately deepiy 
notched, antennæ only extending to half the length of the thorax, 
black, the first and third joint elongate, equal, the second and 
fourth short, the others very strongly transversely serrate like a 
species of Lamellicorn; thorax about one half longer than broad 
with a blunt angle or tubercle at the middle, and a shallow trans- 
verse sulcus near the anterior margin, the surface closely punctured 
aud clothed with a mixture of black and grey hairs; elytra with the 
base near the suture raised into a bluntelevation ortubercle, depressed 
in front of the shoulders, the latter angulate, the surface pubescent 
like the thorax with two narrow grey undulate transverse bands at 
the middle, which are open at the sides but joined at the suture, a 
very small whitish spot is also placed at the apex near the suture; 
underside and legs similarly black and white pubescent, posterior ‘ 
femora strongly incrassate with a small tooth near the apex and a 
band of whitish pubescence at the middle. 
Fianarantsoa. 
This is a highly interesting species on account of its large size and 
the structure of the antennæ which in no other species of this group 
with which I am acquainted, reaches the development in regard to 
the serrate joints, as in the present form ; a much smaller specimen 
in which the femora are much less thickened and do not extend to 
the apex of the abdomen, I take to represent the female sex ; there
