DICRANOMYTA. T3 



Common in damp, shady situations, especially in hollows, having 

 a spring at the bottom. 



This species can always be easily recognized by the pale band 

 at the tip of the femora. I have found some specimens near the 

 Sharon Springs, jS^. Y., without any apparent brown clouds, 

 except the stigma ; but this pale band and the other characters 

 undoubtedly refer it here.

Head black, front silvery ; palpi and antennae black ; the last 

 joint of the former ends in a slender, cylindrical prolongation, which 

 might be taken for a fifteenth joint. Thorax black, shining above, 

 silvery on the pleuros ; halteres with a blackish knob ; feet pale 

 brown, coxoe pale. Abdomen brownish, margins of the segments 

 more or less pale. Wings pale brownish, stigma darker brown. 



Hab. Trenton Falls, N. Y. 



In 1859 I had identified this species with the European D. 

 morio Fab, Since then I conceived some doul)ts about this 

 identity {Proc. Acad. Nat. Set. Phila. 1860, p. 17), but I have 

 not had an opportunity as yet, for comparing a series of speci- 

 mens from Europe and from North America. The latter seems 

 to have somewhat darker wings, but by all means the discrepancy 

 is hardly anything more than one of coloring. The peculiar 

 structure of the last antennal joint has already been noticed by 

 Meigen (Vol. YI, p. 274). 



16. D. piilbipeiiiiis 0. S. % and 9 • — Obscure brunnea ; alis im- 

 maculatis, in regions apicali sparse pubescentibus ; stigmate pallide 

 infuscato ; vena longitudinali prim§, in secundam (non in cos,tam) in- 

 curvS, ; vena auxiliari pone prsefurcse initium extensa. 



Dark brown ; wings immaculate, sparsely pubescent in the apical region ; 

 stigma pale brownish ; the first longitudinal vein is incurved towards 

 the second (and not towards the costa) ; the auxiliary vein is prolonged 

 beyond the origin of the prsefurca (Tab. I, fig. 2). Long. corp. 0.35 — 0.38.
