Fam. RHIPIPHORIDAE. 
33. Geoscopus languidus (Acosmius), op. cit. 11, 286. 
The type, again still unique in the British Museum, agrees 
well in generic characters with G. murimus Gerst. 
The streaks on the thorax and two transverse fasciae on 
the elytra, one about the middle and the other apical, 
that Walker describes as “ non-tomentosis,” are in reality 
as pubescent as the rest, but the pubescence is dark. 
Fam. MORDELLIDAE. 
34. Mordella composita, op. cit. 11, 286. 
M. tonkinea Pic. 
@M. ocrogutratTa Montr. 
A widely distributed Oriental species, liable to some 
variation in the white markings. In the type the basal 
white border of the thorax is of almost even width, the 
antemedian transverse fascia is interrupted in the middle 
and produced backwards in a longitudinal streak each side 
of the interruption. Also there is a short oblique white 
streak on each elytron bordering the scutellum. These 
last, as well as the longitudinal streaks on the thorax, are 
sometimes wanting, and in some cases the transverse fascia 
of the thorax is continuous. The other spots are as 
follows: a round one in the middle of each elytron near 
the base, and a transverse marginal streak a little behind ; 
these with the scutellar streak are almost on an arc of which 
the humeral angle is the centre. Behind these but before 
the middle is a round spot touching the sutural stria, and 
rather more than halfway between this and the apex is 
another round spot about the middle of the disc. This 
last is liable to elongation in a transverse direction, while 
that towards the base is liable to longitudinal elongation. 
The identity of this species with M. octoguttata Montr., 
from Woodlark Island is a little doubtful on account of the 
widely different locality. Fairmaire records what is 
probably the same species from Burma (Ann. Soc. Ent. 
Belg. 40, 1896, p. 61) as M. octoguttata.
