collections. Spinola did not think his species would prove 
even congeneric, but he relied on the grooving of the femora, 
a very common character which occurs in a greater or less 
degree in other genera of Necrobiides and Enopliides, and 
would very probably have not been mentioned by Laporte. 
It is, however, more probable that the species are distinct. 
Before makers of catalogues place specific names as syno- 
nyms, they should satisfy themselves that some competent 
specialist has had both insects before him and at the same 
time.

I have already (‘Trans. Ent. Soc. 1877, p. 260) remarked 
that Hydnocera is an essentially American genus. ‘The 
Hastern species prove on examination to have a wholly 
different antennal structure, and have been separated under 
the name Neohydnus; and while [ admit that I cannot at 
present discover good characters by which the present insect 
might be generically separated, yet I feel confident such will 
be found, unless the insect can be considered not truly 
endemic. 
‘T'wo examples sent by Mr. Marshall appear to be identical 
with this; but the tarsi are darker than Boheman’s descrip- 
tion would lead one to expect, and in one at least are nearly 
black. 
I believe they were captured at Salisbury ; 4990, 6896.

The locality for these examples is Natal, Frere, under dried

Hab. Mashonaland, Salisbury (Marshall). 
The head and thorax are black, inclining to be pitchy, and 
with the whole body are densely covered with floccose pile ; 
they are densely punctured, so as to be dull; the elytra are 
shining, dark blue, and with series of very large oblong
