108 C. R- Osten Sacken: Dlptera 



coaleseent stripes; sides of the dorsum fulvous. Abdomen brownish- 

 fulvous, the middle portion of the segments, including the hind margin, 

 more distinctly brownish. Halteres yellowish. Legs brown, shining, 

 clothed with long fulvous pile; coxae fulvous-pollinose. Wings brown^ 

 darker towards the base. — Two very imperfectly preserved specimens. 



— Length 6 — 7 mm. 



Damalina cyanella n. sp. Q.. Head black, grayish pollinose; 

 antennae and mystax black. Thorax dark metallic-blue; humeri, pos- 

 terior part of the mesonotum, scutellum and metanotum grayish-pollinose. 

 Abdomen metallic-blue, shining above. Halteres with a brownish stem 

 and a reddish knob. Legs black, shining, beset with black hairs, es- 

 pecially the hind tibiae. Wings tinged with brown, the basal portion, 

 before the discal cell is dark-brown, with a bluish reflexion. — A single 

 imperfect female. — Length 6 — 7 mm. 



NB. I have already alluded above to the peculiar venation of my 

 only specimen. The very narrow discal cell emits only two veins at 

 its end, instead of three and thus there are only four posterior cells, 

 instead of five. As the specimen has but one wing left, I am in doubt, 

 whether this is a permanent character or an individual abnormity. 



Stichopogon peregrknus n. sp. Q.. Whitish-gray, front, vertex 

 and mesonotum in the middle brownish; antennae black; mystax white; 

 abdominal segments with brown spots in the middle; on the first seg- 

 ment, the spot is small; on the second it is a large triangle, the base 

 of which occupies the whole breadth of the posterior margin of the 

 segment and the tip almost touches the anterior margin; the third seg- 

 ment is almost altogether brown, except an interrupted, narrow margin 

 anteriorly; segments 4 and 5 have brown triangles, like the second 

 segment; segments 6 and 7 are nearly brown, like segment 3; segment 

 7 is grayish. Venter gray. Halteres yellow; the dark ground-color of 

 the legs is entirely concealed under a gray pollen. Wings subhyaline. 



— Length 4 — 5 mm. — One male. 



NB. This species diifers from its european congeners (at least in the 

 specimen before me) in having the fourth posterior cell not petiolate; 

 it is subsessile, as its contact with the second basal cell is almost 

 punctiform. 



Laphria. There are a dozen species of this genus in the col- 

 lection. Their general character is very much like that of the Laphriae 

 from the Malay Archipelago. Owing to the large number of species 

 already described and to the insufficiency of many of the descriptions
