Empididae. 151 



black or blackish browii; the upper branch of the cubital vein origin- 

 ating with an acute angle, and diverging. Stigma brownish. Halteres 

 black or blackish. 



Female. Quite sirailar to the male; the dorsocentral and acro- 

 stichal bristles of the same length as in this; front metatarsi simple, 

 half as long as tibiæ, and as long as the three following joints; hind 

 tibiæ simple, 



Length 3 — 3,ft mm. 



This species is easily known from the two preceding by the short 

 dorsocentral and acrostichal bristles, and by the former not being 

 long behind. It must be very like pinetonim Zett., but this species 

 seems to be smaller and to have the middle tarsal joints shorter 

 than broad. — My specimens of the present species belong to the 

 var. brevifurca Strobl (1. c). — I am somewhat inclined to think, that 

 dypeata Zett. may be cornicida, as the author speaks of the distinct 

 pilosity of thorax, and as he mentions the species from Denmark, 

 sent by Stæger; in the collection in our museum cornicula was found 

 determined by Stæger as dypeata, while dypeata w^as not present in 

 the collection, 



H. dypeata is rare in Denmark, only four specimens have been 

 taken; Amager (the author) and at Frederikshavn and on Læsø 

 (H, J, Hansen); the dates are from ^7" to the first half of July. 



Geographical distribution: — The species seems to be widely 

 distributed, from southern Sweden down to South Africa, If dypeata 

 Zett, is identical with cornicula the present species is not known 

 north of Denmark,
