[March-June 
I have compared the present species with a paratype of 
fumomarginatus Hine in the Hine collection, and believe it 
to be abundantly distinct. Fumomarginatus is larger, 18 
mm., stouter, and with a broader frons and different an- 
tennse. Specimens of the present species in the Hine col- 
lection are labelled unipunctatus Bigot, but in Hine’s MS 
notes there is a statement that unipunctatus Bigot = jila- 
mensis Hine. Specimens of jilamensis before me from 
Lancetilla, Tela, Honduras, (Figs. 6, 6a, 6b) agree perfectly 
with Hine’s description, and are practically topotypes. They 
differ quite markedly from the present species in the shape 
of the frontal callus and antennse, in the rather prominent 
mid-dorsal abdominal stripe, and in the green banded eye. 
On the other hand Krober (1939, p. 133), stating that the 
type of unipunctatus is a poorly preserved specimen, uses 
the name for specimens from French Guiana, which appear 
to be different from jilamensis Hine, fumomarginatus Hine, 
and the present species. Krober ’s fumomarginatus, from 
Costa Rica, is with little doubt the present species. In view 
of the reported condition of Bigot’s type, it is still possible 
that Hine and Krober were wrong, and that the present 
species is really unipunctatus, but since anything approach- 
ing certainty in the matter is at present impossible, it seems 
better to describe the present species as new. The specimen 
mentioned by Osten Sacken (1868, Biol. Centr.-Amer., Dipt., 
I, p. 56) from Bugaba, Panama, may well have been this 
species.
