28 Pipunculidae. 



Female. Vertex and frons narrow, frons black and shining above^ 

 silvery below, above the antennæ an elongated knob or keel ; antennæ 

 with the third joint paler than in the male and with a distinct rostrum. 

 Hypopygiiim small, pear-shaped, the basal part with a furrow, the 

 ovipositor not longer than the basal part, straight or nearly so. 

 Claws and piilvilli larger than in the male. Wings with the stigma 

 shorter than next costal segment. 



Length 3 — 3,5 mm. 



This species is very similar to fuscipes, but it is in the male 

 known by the not rostrate antennæ and smaller impression on hypo- 

 pygium, and in the female by the narrow frons and the smaller 

 hypopygium with a furrow. I have compared my specimens with 

 typical specimens kindly sent me from Mr. Becker. 



P. montium is rare in Denmark, only five specimens have been 

 taken, two males and three females, Ruderhegn (H. J. Hansen), 

 on Langeland at Lohals (the author), in Jutland at Albøge (Kryger) 

 and at Ry (the author) and on Bornholm at Hasle (H. J. Hansen); 

 the dates are ^Ve — "/?; it was taken for the first time in 1883. One of 

 my females (Albøg) has pale humeral knobs and the middle cross- 

 vein a little more towards the base, it might perhaps be the undescribed 

 female to Koivarzi, but it is only 3 mm. 



Geographical distribution: — Resides from Denmark known from 

 Germany, Bohemia and Switzerland.
