438 Phoridae. 



long bristle. Abdomen short and broad. Hypopygium small. Legs 

 somewhat slender, withoiit bristles, short-hairy; posterior tibiæ with 

 small apical spiirs. Ciaws small; pulvilli and empodium, if present, 

 very small. Wings as in Phorinae; costa reaching to aboiit the middle, 

 with short cilia; third vein with a small fork or unforked, and with 

 or without fme bristles. Female: Body flat and oval. Head with the 

 frons broader than in the male and the eyes smaller; frons quite 

 without bristles. No ocelli. Thorax relatively shorter and broader 

 than in the male, and fitting close to abdomen. No scutellum. Pleura 

 constructed as in the male. Abdomen with six free segments. Legs 

 shorter and more robust than in the male and with the femora broader. 

 Wings and balteres absent (Enderlein and Schmitz mention a small, 

 vestigial wing-rudiment? in shape of a very small, hairy process). 



The developmental stages are not known, only Donisthorpe 

 mentions (Entom. Record. XXVI, 1914, 276) the pupa of Lubbocki; 

 they are termed small and red, but otherwise not described. The 

 species are parasitic on ånts (Formica fiisca, picea and rufibarbis), 

 and the larva quits the ant-pupa before it pupates itself. 



Of the genus three European species are known (or perhaps 

 four, as the probable male of Dorni may perhaps be a separate speciesj. 

 One species has hitherto been found in Denmark,

Male. Of this species I have seen only the female, for the male I 

 can, therefore, only reproduce VerraH's description: 



Nigra, nitida; abdomine triangulari, segmento tertio parvo; 

 femoribus posticis basi flavidis; alis apice latis, flavido-hyahnis, 

 costa ad basin subciliata, vena cubitali ad medium costae extensa 

 subcostali parallela, venulis undulatis. Long ^U lin. 



Broad, flat, shining; frons very broad, the eyes scarcely occupying 

 each one sixth of the width of the head; it is moderately shining,
