hemoptera—at any rate until an examination of the type shall 
prove the contrary. 
Thus I regard Psewdolycus as at present consisting of four 
species, viz., hemorrhoidalis, Fab., luctuosa, Boisd., marginata, 
Guér,, and hemoptera, Guer., to which I have to add two new 
ones. The following table indicates characters by which the six 
may be indentified :— 
A. Prothorax having two ridges, which diverge obliquely hindward 
from the middle of the median line enclosing a triangular depres- 
sion. (Antenne unicolorous). 
B. Prothorax distinctly cordiform. 
C. Prothorax notably wider than long. (Hind 
tarsi unicolorous) hemorrhoidalis, Fab. 
CC. Prothorax not (or scarcely) wider than 
long. (Base of hind tarsi testaceous) ... Juctwosus, Boisd. 
BB. Prothorax scarcely cordiform. (Base of hind 
tarsi testaceous) marginatus, Guer. 
AA. Middle longitudinal line of prothorax continu- 
ously convex or carinate. (Antenne not 
unicolorous) 
B. Surface of prothorax very uneven through the 
presence of large impressions and fovee. 
C. Prothorax notably longer than wide, and 
feebly cordiform elegantulus, Blackb. 
OC. Prothorax only slightly longer than wide, 
strongly cordiform ... ... hemopterus, Guer. 
BB. Surface of prothorax even or nearly so .. puberulus, Blackb. 
P. hemorrhoidalis, Fab. I have not seen this species except 
from Tasmania. So far as my observation goes the colour is 
uniformly black, except the elytra, which vary from entirely 
black (if atratus is a var. of it) through forms in which only the 
apex of the elytra is red (type), and others in which the sides, 
or the sides and suture (cinctus), as well as the apex are 
red, to «a form in which the elytra are entirely red (figured by 
Mr. Champion, /oc. c2t., and in my collection). From its nearest 
allies it is distinguishable also by its prothorax of evidently 
{though not at all strongly) cordate form, and quite strongly 
transverse. 
P. luctuosus, Boisd. The species to which I apply this name 
occurs in Victoria, and closely resembles hemorrhoidalis, Fab. 
In colour its elytra vary exactly as those of hemorrhoidalis do, 
and in addition the specimens with red elytra have some red 
blotches on the prothorax. The base of the basal joint of the 
hind tarsi seems to be invariably whitish testaceous. The pro- 
thorax is sculptured on the upper surface like that of 
hemorrhoidalis, but is scarcely wider than long, and is very 
evidently more cordiform. The antenne are like those of 
hemorrhoidalis in their dilated joints Bone very strongly dilated 
in both sexes.
