102 Phoridae. 



the middle, middle tibiæ with a pair near the base and an anterioi 

 near apex, hind tibiæ with two anterior, one near middle or abovc 

 and one near apex, and with three to four or five dorsal bristles. 

 Wings somewhat yellowish, veins brownish yellow; costa reachino 

 well beyond the middle, 1 about equal to 2; fork acute; costal cilia 

 short. Halteres pale yellow. 



Female. Quite similar to the male; the abdominal segments of 

 about equal length with exception of the longer sixth segment, which 

 has long hindmarginal bristles only below; the fifth segment is slightly 

 or not at all chitinized and hence more or less corrugated above and 

 of a more deep black colour than the rest of abdomen. 



Length 2,5 — 4 mm. 



Remarks: In my material the hind tibial bristles are present in a 

 number from 5 to 6, but it is recorded that the number may be 7, 



Ch. caliginosa does not seem to be common in Denmark, Dyre- 

 haven, Holte (Th. Mortensen, Rosenberg) and at Hejls south of 

 Kolding (the author); the dates are ^U — ^Vt. At Hejls it was taken on 

 stems of trees together with thoracica, and at Holte Rosenberg took 

 it in a fox's den. Pupæ were taken in Dyrehaven in a mole's nest 

 bn ^^4, they developed on ^V4 — ^^U (Rosenberg). 



Geographical distribution: — Europe down to Italy, towards 

 the north to middle Sweden, and in Siberia. 



2. Paraspinipliopa Malloch 1912. 



(Spiniphora Malloch, Glasgow Naturalist J, 1909, 26). 



Species of medium or relatively large size. Frons more or less 

 broader than high, with strong bristles forming three transverse 

 rows with four bristles in each row, the anterior rows often very 

 convex; one pair of strong supraantennal bristles, directed back- 

 wards. Eyes hairy. Antennæ inserted more or less to much below the 

 middle, third joint of ordinary size, or somewhat large, elongately 

 lemon-shaped, generally smaller in the female; arista dorsal, it is 

 sometimes more pubescent in the female than in the male. Clypeus 

 sometimes a little protruding in the female. Palpi with the bristles 

 sometimes shorter in the male than in the female, in Bergenstammi 

 quite short in the male; when examined with a lens the palpi show 

 on the upper or exterior surface more or less distinctly a small ex- 

 cavation, tliis is due to a special sensory organ as mentioned by 

 Schmitz (Biol. Zentralbl. 37, 1917, 33). At the sides of the oral aperture
