This species stands near poonindiensis and Meyricki in my 
tabulation, differing from both in its entirely black color and also 
in the stronger and less close puncturation of its elytra. It also 
resembles S. brisbanensis, but is larger, wider, and much more 
strongly punctured. The unique example before me is probably 
a female and it is not unlikely that the front tibie and perhaps 
the head of the male are rufescent.

This species seems to oscillate between the groups of 
poonindiensis and. flavifrons in my tabulation, as it is exactly of 
the size which I selected as the limit of those groups. It can 
however be at once separated from all the described species in 
both groups by the markings of its prothorax which consist of a 
bright yellow and very sharply defined marginal spot on each 
side. It comes near the preceding species (S. Styx) in the punc- 
turation of its elytra but differs widely in color in less convex 
form and in its prothoracic puncturation. The unique type is a 
male; probably the female has darker front tibiz and head.

The unique example of this extremely minute insect has its 
head and prothorax bent down in a manner that precludes a suf- 
ficient examination of its prosternum but as far as I can see the 
median part of the prosternum is longitudinally depressed as in 
the preceding species. Owing to the (in this genus) very excep- 
tional sculpture of the elytra I deem it probable that a satisfac- 
tory dissection of specimens would lead to the removal of this
