Order DIPTERA 
The few but nevertheless \ery interesting Diptera 
collected by ^Ir. R. C. Mtu^jihy on his expedition to South 
Georgia belong to four species of which three were from the 
Island of South Georgia and one. f'sciuiolfcrsia sf^iiiifcra 
Leach, from Trinidad Islet. (Jf the three species from South 
Georo-ia two were found to lie new.

Color almost uniformly yellowish — testaceous. Eyes convex, 
widely separated, not hairy. Ocelli absent. Palpi four-jointed, 
apparently is in brozvni. Antennae six-jointed, first joint short and 
stout, second joint longer than third, but not as long as the third and 
fourth joint combined, the fifth a little shorter than third, sixth joint 
longer than second. Prothorax rather feebly produced in front, from 
apex to base a longitudinally impressed median line; near apical margin 
a deep transverse impressed line which is interrupted at middle ;

Halteres very small, knob-like. Abdomen with nine segments, which

Two specimens, both females, collected in alcohol together 
with' specimens of a species of Collembola, Isotouia gcorgiaiia 
Schaff.. near the Bay of Isles, South Georgia, in January and 
February, 1913. 
Differs from the female of £. broz^'iii in having six- 
jointed antennpe, halteres normal, knob-like, and the naked 
eyes, characters sufficient for the erection of a new genus for 
this species. However, in the aljsence of ni.ales and the verv 
limited material at hand 1 ])refer to ])lace it provisionallv in 
the genus Erctiiioptcra. The onlv species of the genus
