44 STUDIES IN AMERICAN EPHYDRIDAE (dIPTERA) 
Azotes . — Of the specimens examined, the males have the third 
antennal joint mostly yellow and the pleural markings obsolete. 
Although the series I have is small it is noticed that there are 
no specimens of both sexes from the same locality. The only 
females I have seen are the three from Manahawkin, New Jersey. 
Before seeing these I could not satisfactory characterize the 
species except in the males, and had about concluded that the 
females were inseparable from those of vittata. As soon as the 
Manahawkin specimens were examined the stout, weakly setu- 
lose legs at once indicated their relationship. 
Synonymy . — I suspect this to be N. hella of Loew, mainly on 
account of the ash gray color and the broad mesonotal stripes, 
but it is strange that Loew does not mention the peculiar devel- 
opment of the abdomen. On the other hand my specimens 
have only a spot on the upper part of the pleura, and the abdomi- 
nal spots are arranged in two series or the lateral ones are short 
and small. 
Notiphila loewi new name 
?1862. Noiiphila unicolor Loew, Mon. Dipt. N. Am., i, 137, (nec Walker, 
1860). 
This species begins a group with non-vittate thorax, and hair- 
like facial bristles in more extended series. The abdominal 
markings are reduced to two median series of triangular spots, 
or the abdomen may be immaculate. The present species has 
the fore tibiae and tarsi black and the middle and hind ones yel- 
low. The cilia of the male middle tibiae is not well developed, 
the bristles or hairs being more recumbent. Their femora, how- 
ever, are distinctly and densely ciliate. 
Description . — cf. Black; base of third antennal joint, palpi, halteres, 
knees, tibiae and tarsi except median ring on hind tibiae and apical joint of 
tarsi, tawny or yellow. Fore tibiae and tarsi, black. Tarsal fascicle black. 
Wings brownish. 
Opaque, light olivaceous with ochreous tinge including femora; sometimes 
dorsal surfaces darker to brownish, and pleura and metanotum lighter. Frons 
darker with light orbits; vittae indistinct. Face and cheeks yellow or ochreous 
to whitish. Mesonotum faintly vittate; mesopleura with small spot or thorax 
entirely immaculate. Abdomen with a median pair of brownish triangular 
spots on segments; sometimes these extend to lateral margin, are limited to a 
pair on third segment only, or are entirely wanting. 
Frons subquadrate; orbits slightly converging. Face three-fourths as 
broad as vertex, one-fourth longer than broad, with shallow foveae and a weak,
