NOTES ON AMERICAN TRYPETIDyE (Diptera) II. 
By Marston Bates,

Museum of Comparative Zoology, Cambridge, Mass. 
The species considered in this paper all belong to groups 
which have the “Aciura” wing pattern-— black, with hyaline | 
indentations. The various genera have little else in common, 
and belong to widely separated sections of the family, al- 
though they are sometimes placed together. The group of 
species placed in Aciurina by Curran (1932, p. 9) will be 
considered in a separate paper. I am indebted to Mr. E. T. 
Cresson, Jr., of the Philadelphia Academy of Sciences, and 
to Mr. C. H. Curran, of the American Museum of Natural 
History, for part of the material on which this work is 
based. 
Genus BLEPHARONEURA Loew 
Loew, 1873, p. 272 (type, B. poecilog astro, Loew, sole 
species) 
The front is about as broad as one eye, less than twice as 
high as broad. There are two pairs of upper, and two of 
lower orbital bristles; the verticals and ocellars are well 
developed. The third antennal segment is about as long as 
the second, rounded. The face is excavated, with the oral 
margin projecting. The dorsocentrals are behind the an- 
terior supra-alars ; there are three pairs of scutellars. The 
venation is shown in Fig. 2; the third and fifth veins are 
spinose above. 
The above notes are based on the genotype, with which 
the following new species agrees closely in structure, de- 
spite the very different wing pattern. 
Blepharoneura hirsute, sp. nov.
