STUDIES IN AMERICAN EPHYDRIDAE (dIPTERa) 
those of Europe in being somewhat darker, especially respecting 
the antennae and legs, and possibly the frons and face are 
slightly broader. 
Before me is a female; Toronto, Ontario, Canada, VII, 4, 
1913, (INI. C. VanDuzee); which is evidently not conspecific with 
the above series, but I do not care to describe it as new, as it is a 
female. The general color is more yellowish; second antennal 
joint black; facial bristles weak; abdominal spots more con- 
nected at bases; fore tibiae and tarsi black. Evidently, how- 
ever, it belongs to this group. 
Xotiphila punctifera new species 
?1830. Notiphila exotica Wiedemann, Auss, Zweifl. Ins., ii, 590. 
?1896. Notiphila bellula WiUiston, Trans. Ent. Soc. London, 1896, 390. 
This and the following species of the group differ from riparia 
in their greater opacitj^, and the more or less irrorated or vittate 
mesonotum. The vittae, however, may not be distinct, but 
there are some indications or suggestions of such mesad of the 
intra-alar series. The abdomen is more opaque, with the mark- 
ings not so dark and shining. 
In the present species the frons is broad and the hairs of the 
arista numerous as in riparia, but the mesonotum is irrorated 
with brown dots at the bases of the setulae and shows faint vittae. 
It is closely related to, and may be a subspecies of, erythrocera 
Lw. Length. — 3.5 to 4 mm. 
Holotype . — 9 ; Corumba, Brazil, May, (H. H. Smith), [A. N. 
S. P. No. 6109]. Paratypes . — 1 cf , 1 9 ; topotypical. 
Specimens Examined . — 2 o’, 3 9- 
Brazil: Corumbd, May, (H. H. Smith), 1 cf, 2 9, [A.N.S.P.]. 
Paraguay: San Bernardino, (Barbarczy), 1 o’, 1 9, [H. N. M.]. 
Synonymy . — I think this will prove to be Williston’s species, 
but cannot say this of Wiedemann’s. The synonymy of the latter 
is based on the yellow palpi and antennae and the four series of 
abdominal spots. The examinations of the types will readily 
establish the true synonymy. 
Variations . — I have also a specimen from Brazil (H. H. Smith), 
which has the facial bristles weaker and more hair-like, in series 
of four extending higher up on the face. The mesonotal vittae 
are more apparent, but the irrorations are less distinct. It was 
received from Prof. Williston under a manuscript name.
