apex. Thorax very transvei’se, punctate, slightly rounded on the 
apex, advanced at the anterior angles, the sides from thence 
sloping out-wards for one-third of the length, then shortly and 
lightly emarginate, and again near the posterior angles more 
deeply emarginate, giving the sides a trilobed appearance, the base 
is broadly and sub-triangularly lobed, the central pair of longitu- 
dinal ridges bulges out in the middle and does not extend to the 
base, the next is interrupted in the middle, the outer pair is inter- 
rupted and occupies only the basal half. The elytra are shortly 
and broadly ovate, wider than the thorax and about four times the 
length, with 10 rows of large granulose punctures, the interstices 
consisting of small squamose sub-elongate tubercles, the 3rd and 
5th interstices lai’ger and sub-costate at the base. The anterior 
tibiae with two strong compressed triangular teeth on the outside, 
one terminal. 
Long. 5^, lat. 3^ lines. 
145. Trox asperrimus, n.sp. 
Black, opaque, sculpture very rough. Head rather prominently 
bituberculate in the middle, roughly and rugosely punctate. 
Thorax transverse, rounded and widened from the anterior angles 
to behind the middle, then a small rather abrupt emargination, the 
posterior angles prominent, the base I’ounded and lobed in the 
middle, the entire disk so rough and irregular as to make the three 
pairs of ridges appear like oblong tubercles without order. The 
elytra resemble those of T. nodicollis in form and sculpture, but 
are much coarser and rougher. Legs short, a minute tooth in the 
middle of the outside of the anterior tibiie, with one or two 
extremely minute ones above. 
Long. 4 lines. 
146. Trox vitreomaculatus, n.sp. 
Black, opaque, squamose. Head with two comparatively large 
round tubercles in front, the clypeus triangularly rounded. Thorax 
transverse, the sides with two emarginations forming three con- 
spicuous lobes, the three pairs of longitudinal ridges of normal
