differing, however, in the diverging antennary tubers, and conse- 
quently the remoteness of the antennz at their insertion. 
Nonyma egregia. 
N. fusca, pube grisea tenuiter vestita. 
Hab. Natal. 
Brown, with a thin greyish pubescence ; head very convex between 
the tubers ; prothorax with large scattered shallow punctures; the lateral 
tooth small, rather behind the middle; scutellum rounded behind, 
covered with a very dense whitish pile; elytra punctate-striate, the in- 
terstices rather more elevated posteriorly, the third especially, uniting 
with the fifth, being the most prominent, the apex of each elytron 
rounded ; body beneath and legs chestnut-brown, with a very sparse 
grey pile; antenne not quite half as long again as the body. Length 
34 lines.

In the first part of my ‘ Longicornia Malayana,’ recently published, 
I have pointed out the tendency of certain genera of the “ Exocen- 
trine ” toa peculiar arching of the prothorax, forming with the head 
a complete curve. I may here cite Cyrtinus of Leconte as one of 
the best-known amongst them. This arching varies in extent; in 
this new genus it 1s very decided, although less so than in one or 
two others. None of these genera have the antenne plumed; and 
in this respect Biasmia may be distinguished from them ; the tuft or 
plume is not, however, uncommon in this subfamily. Moreover the 
elytra of Biasmia are perfectly regular, have neither spines nor any 
tendency to a concavity in their centre together with the correspond- 
ing conyexity behind, but, on the contrary, are rather depressed than 
otherwise. The single species of the genus is a somewhat robust form 
for this group.
