ed from above; legs entirely concealed 
from above; two basal joints of tarsi 
small, third elongate. 
To examine nil parts carefully would 
need very careful dissection, and as the 
head of the largest specfes before me is 
less than one two-hundredth part of an 
inch in length, I have been unable to 
properly dissect it; the antennae may 
really he eleven-jointed; but if so, the 
joint I am unable to see must be conceal¬ 
ed by the overlapping portion of the head. 
The genus, however, is so remarkably dis¬ 
tinct by the characters, which are readi¬ 
ly observed under the microscope with¬ 
out dissection, that no confusion is 
likely to arise from this cause. I am un¬ 
able to count the segments of the abdo¬ 
men. The outer margins (seen when 
the lower surface is examined) appear 
to be formed of a thin, continuous flap, 
of which that portion formed by the pro- 
thorax is the deepest, and that by the 
bead is the finest. The prolongation 
backwards of the hind angles of the pro- 
thorax is much more apparent from the 
under than the upper surface. The in- 
tereoxnl process of the mesosternum is 
wide, and more parallel-sided than in the 
figure () given of Limulodes; the middle 
coxae are ’also wider, larger, and more 
distant. .Roth the process and coxae 
however, are entirely concealed by the 
overlapping prosternal process. 
•In Matthew's main figure on plate 16 
the scutellum appears as being absent, 
but on plate 23, fig. 13, a distinct scu- 
telluin is shown, and in the generic de¬ 
scription it is said to be “brevissimum, 
la tissimum. triangulare.”

Uludwayia Ovata, n. sp. 
Pale reddish castaneous, appendages 
and tip of abdomen paler, closely covered 
with short Sericeous pubescence. 
Head about twice as wide as long. 
Prothorax very large, almost half total 
length, rather strongly convex, sides 
feebly rounded, except towards the apex, 
where they are strongly rounded; length 
of sides almost equal to greatest width. 
Elytra at the base narrower than, and 
clasped by base of, prothorax, sides 
gently decreasing in width from base to 
near apex, apices widely and separately 
rounded. Intercoxal process of pro- 
sternum slightly produced on to metas¬ 
ternum and entirely concealing middle of 
mesosternum; apices widely rounded, 
apex of abdomen notched. Femora wide; 
length § imm.
