152 Orthorrapha brachycera. 



Occipnt grev with greyish white, farther down white, hairs; occipito- 

 orbital bristles black, somewhat strong. Antennæ blackish, first joint 

 somewhat greyish pruinose, with black, and beneath at the base some 

 white hairs. Thorax blackish with tvvo, somewhat broad, distinct, 

 bright yellow stripes; the disc clothed with short, depressed, whitish 

 and erect, black hairs. Sterna and pleura grey with long, white hairs. 

 Abdomen black, slightly shining, the segments with whitish yellow 

 hind margins ; the first segment greyish at the sides, the second, third 

 and fourth segments with silvergrey, somewhat triangular spots later- 

 ally at the hind margin; on the fifth and sixth segments a transverse 

 band, somewhat incised in the front margin; the seventh segment 

 black, shining. The first four segments are sparingly clothed with 

 depressed hairs which are black on the black parts, white on the 

 spots; the first segment has somewhat longish, white hairs at the 

 sides; the last segments have short, erect black hairs, the fourth 

 segment with both depressed and erect hairs. Venter greyish black 

 with yellow incisures; the first three segments with longish, white 

 hairs, the last four with short, erect black hairs. Legs with the 

 femora greyish black, tibiæ yellow, black at the apex, tarsi yellowish, 

 blackish towards the ends. Wings hyaline, the veins dark brown; 

 the fourth posterior cell open; stigma grey. Halteres blackish, the 

 peduncle pale towards the base. 



Length 12 mm. 



My only specimen is somewhat immature; it has the legs some- 

 what pale and the wing stigma grey, but otherwise it agrees rather 

 well with Loew's description, as also in the faet, that the head is 

 somewhat narrow; I feel certain therefore with regard to the de- 

 termination. 



T. microcephala is very rare in Denmark, only one specimen 

 has been caught; it was taken in Dyrehaven on ^'^li (Rosenberg) in 

 a hollow tree, and it was somewhat immature, the pupa has pro- 

 bably been lying in the tree. 



Geographical distribution : ^ — Middle Europe.
