The species is characterized farther by some raised lines 
on each elytron, of which one near the suture is more distinct 
than the rest, the intervals between which are somewhat 
irregularly punctured. In addition to the numerous small 
brown dots each elytron has four small brownish patches — - 
one oblique basal, one oblique median, the third also oblique 
at some distance from the apex, the last at the apex. 
Diadelia cc- fas data, sp. n. 
Angusta, elongata, fulvo-griseo leviter pubescens ; maculis minimis 
brunneis variegata ; prothorace supra leviter trituberculato ; 
elytris singulis fasciis duabus brunneis valde obliquis ad suturam 
connexis, apicibus subobliquiter truncatis ; antennis corpora 
longioribus, articulis basi pallidis, apicibus brunneo-ferrugineis.

I am not certain that I do right to refer this species to 
Diadelia . It has slightly larger eyes and a narrower front 
to the head than has D . hiplagiata , and the mesosternal 
process is almost flat and is destitute of a tubercle. The 
elytra bear indications of raised lines, in the intervals between 
which they are irregularly and not very thickly punctured. 
There is a slight hump or swelling on the disk of each 
elytron at a short distance behind the base. The apices of 
the elytra are less obliquely truncate than in hiplagiata. The 
species may further be recognized by the fulvous-grey pubes- 
cence, minutely speckled with brown, and by the two oblique 
narrow brownish bands on each elytron — one beginning close 
to the margin just in front of the middle and directed back- 
wards to the suture, the other at some distance behind the 
middle and directed forwards towards the suture, where a 
short longitudinal band joins the two. 
Ancylistes bellus , sp. n. 
A. bicuspi similis, sed differt inter alia elytris fere impunctatis, 
fascia transversa mediana nigro-velutina. 
Hah . Antananarivo ( Kingdon ). 
Head with the eyes small, the front large and slightly 
convex. Prothorax broad and convex in front, abruptly and 
strongly constricted at the base, obtusely and feebly dilated 
above the middle of each side ; the disk marked with nume- 
rous longitudinal and slightly curved striae. The elytra, 
strongly and transversely depressed behind the highly elevated 
and acute basal tubercles, are crossed at the middle by a
