Dolichopodidae. 403 



or slightly and truncately pointed; the second overlaps the third 

 triangularly in the middle on the inside, and above on the outside; 

 arista dorsal, somewhat longer than the antennæ, its first joint short. 

 The first antennal joint is bare, the second has small bristles at the 

 apical margin, the third is distinctly hairy, and the arista short-hairy. 

 Epistoma somewhat broad, and broadest in the female; the clypeus is 

 short, it is indistinctly separated from the epistoma by a small notch or 

 tubercle at each side; it is somewhat arched. with the lower margin 

 a little angular and forming a nose-like protruding point in the middle; 

 it does not reach the lower margin of the eyes. The proboscis is 

 thick, somewhat protruding; it and the oral aperture a little larger 

 in the female than in the male. The maxillary palpi are very large, 

 squamiform, and likewise larger in the female than in the male. 

 Thorax rectangular, somewhat high, and a little arched above; pro- 

 and metathorax small, the former with a transverse row of very 

 small bristles. No acrostichal bristles; there are six dorsocentral 

 bristles, the first generally a little smaller than the other, further a 

 humeral bristle and some small hairs, a posthumeral, only one noto- 

 pleural, a præsutural, but small, three supraalar, and a postalar 

 bristle. The disc has only few small hairs on the front part, but 

 some of them a little strong. Propleura have some hairs and about 

 two bristles. Scutellum with two long marginal bristles, and a smaller 

 hair or bristle on each side. Abdomen depressed, and narrow to- 

 wards the end ; in the male there are five visible dorsal segments of 

 about the same length ; also the small sixth segment is generally 

 seen; on the ventral side there are, I think, four normal segments; 

 the seventh segment is small and quite hidden. Hypopygium small, 

 bent in under abdomen, the base of it with the eighth segment is 

 seen at the apex of abdomen. I have not been able to examine the 

 hypopygium more closely, but there are some ventral lobes or inner 

 lamellæ, and a pair of somewhat linear outer lamellæ with long hairs; 

 they seem to be united in the basal part. In the female there are 

 five visible abdominal segments. Dot-like impressions at the side 

 margins are present on the second, third and fourth segments, at all 

 events in the female. The abdominal segments have small and in- 

 distinct hindmarginal bristles only at the sides, they are longer on 

 the first segment. Legs simple, somewhat slender, hind metatarsus 

 about of the length of the second joint, without bristles. The posterior 

 coxæ have each a bristle; the posterior femora have a preapical 

 bristle at some distance from the apex; front tibiæ with some dorsal 

 bristles; middle tibiæ with three antero-dorsal and three postero- 

 dorsal bristles, and with two or three ventral bristles; besides the
