150 Mr. J. 8S. Baly on the Classification of the Kumolpide. 
Genus Srastuvs, Baly. 
Body oblong, subcylindrical, covered above with rigid suberect hairs, 
beneath with scale-like hairs. Head exserted, perpendicular, oblong ; 
antenne half the length of the body, first joint incrassate, second mode- 
rately incrassate, rather shorter than the first, third and three following 
each equal in length to the second, slender, seventh and succeeding joints 
moderately incrassate, the seventh pyriform, eighth, ninth, and tenth 
moniliform, the eleventh ovate; eyes entire; anterior edge of mentum 
angulate-emarginate ; terminal joint of marillary palpi lanceolate-ovate. 
Thorax gibbous in front, its lateral margin obsolete. Elytra deeply 
punctured, interspaces thickened and elevated here and there into irre- 
gular tubercles. Legs moderately robust ; four anterior thighs armed 
beneath with a short tooth ; basal joint of tars? scarcely longer than the 
second; claws bifid. Prosternwn subquadrate, dilated posteriorly ; its 
anterior margin continuous with that of the episternum. Mesosternum 
subquadrate, its apex dilated, obtuse. 
Type, Stasimus rugosus, Baly. Singapore. 
Stasimus may be separated from all other allied forms by its 
gibbous thorax, tuberculate elytra, and peculiar antenne. The 
single species forming the genus is a native of Singapore. 
Stasimus rugosus, Baly. 
S. oblong, subcylindrical, opake, fuscous; head rugose, closely covered 
with suberect paler hairs; thorax rugose, strongly gibbous in front; 
elytra deeply punctured, the puncturing arranged in irregular strie, 
interspaces thickened and elevated at distant intervals into irregular 
wart-like tubercles, the largest of which is placed near the suture, just 
below the basilar space.—Long 23 lin. 
Hab. Singapore. Collected by Mr. A. R. Wallace. 
Fpistome transverse, triangular, its surface rugose. Thorax rather 
broader than long, narrowing towards the apex, its lateral margin en- 
tirely obsolete, the anterior angle only indicated by an obtuse tooth ; 
anterior half of disk occupied by a strongly raised gibbosity, behind 
which on either side is a broad but ill-defined oblique excavation ; 
whole surface closely covered with suberect pale hairs. LElytra less 
closely but more deeply punctured than the thorax, more sparingly 
elothed with hairs, the tubercles ill-defined, with the exception of one 
or two near the suture ; shoulders prominent. 
Genus TricnoruEca, Baly. 
Journ. of Entom. 1. p. 26 (1860). 
Body subelongate, clothed above and beneath with suberect hairs; an- 
tenne nearly equal in length to the body, filiform, scarcely thickened 
towards their apex, first joint incrassate, second shorter, ovate, third 
~ and following two slender filiform, elongate, nearly equal, the third and
