320 Phoridae. 



unequal, the upper about as distant as the inner bristles of middle 

 row, the lower a little more approximate. Antennæ a little above 

 ordinary size, black, arista short-pubescent. Palpi yellow or dark 

 yellow, well developed and with well developed bristles. Thorax 

 black, very slightly shining, with short, dark brownish pubescence. 

 Mesopleura with distinct bristles of uniform size. Abdomen black, 

 distinctly greyish; it has short, sparse hairs, especially on the hind 

 parts of the segments, slightly longer at the hind margins and the 

 sides, and increasing a little in length behind ; on the sixth segment the 

 hindmarginal hairs are long and conspicuous. Hypopygium of medium 

 size or smallish, globular or knob-shaped, black and shining above, 

 \\itli small and short hairs on the sides; below there is a broad, some- 

 what roundish, triangularly pointed yellowish ventral plate, reaching 

 to about the end of the hypopygium; anal tube of medium length, 

 somewhat high, yellow or somewhat dusky at base, without apical 

 hairs. Legs brown, the posterior the darkest; hind femora with a 

 dense fringe of moderately long, somewhat strong hairs below the 

 basal half; bristles on hind tibiæ rather large, few in number. Wings 

 clear or nearly, veins brownish; costa reaching to the middle or about, 

 1 about equal to 2+3, the divisions about as 13 — 10 — 4, but the 

 relative lengths a little varying; costal cilia full long; angle at fork 

 ordinary, not large; fourth vein a little curved in the origin, for the 

 rest slightly and evenly curved. Halteres yellow. 



Female. Similar; lower supraantennal bristles often smaller; the 

 hairs below hind femora not strong, though distinct; first costal 

 division sometimes relatively longer. 



Length 1,8 to fully 2 mm. 



Remarks: Wood's statement for the group with this species, 

 that the first costal division is not longer than the second, is, as seen, 

 not correct. 



A. diversa is not rare in Denmark; Ermelund, Ørholm, Geel Skov 

 (the author), Holte, Suserup Skov at Sorø (Th. Mortensen), Stensby 

 Skov in South-Sealand, Bogø south of Sealand, Lohals on Langeland 

 and in Jutland at Hejls south of Kolding, Jelling (the auhtor) and 

 Randers (H. J. Hansen); the dates are Ve— Vio; it was taken for the 

 first time in 1882. I have taken it in copula on ^"/s. 



Geographical distribution: — Denmark, England and, according 

 to specimens sent me from Pater Schmitz, Holland.
