below it a weak brownish cloud. Squamulæ yellowish. Halteres 

 whitish. 



Female. Frons bluish black, side dust spots not small but not 

 well defined; pubescence whitish on the middle, black above the 

 antennæ and in front of the ocelli. Antennæ longer than in the male, 

 third joint larger, longer than broad. Thorax and abdomen more 

 coarsely punctate than in the male, the pubescence on the latter 

 short, yellowish, black on the incisures. Abdominal spots less linear 

 than in the male, much resembling those in hhnaculata. Legs quite 

 pale-haired. 



Length 5,8 — 7,5 mm. 



This species is in the male known from the preceding by the 

 white-haired epistoma; moreover my four males have the abdomen 

 much more white-haired (and this agrees with the notes about Meigens 

 type given by Verrall 1. c); the occiput and eyes are paler-haired 

 than in bimaculata, and the tarsi paler. The female is very like 

 noctiluca, but is generally smaller, with smaller abdominal spots and 

 less clouded wings; from the female of bimaculata it should be known 

 by the paler tarsi and clouded wings; finally in both sexes the antennæ 

 are longer I think than in both bimaculata and noctiluca. The female 

 of notata is smaller with smaller abdominal spots and unclouded 

 wings. Zetterstedt, who described the species from Danish specimens 

 had only received the female from Stæger, but in Stæger's collection 

 there were also males. My description is made after Stæger's specimens. 



P. signata, if a distinct species, (see under lugubris) seems to be 

 rare in Denmark, we have only seven specimens probably taken in 

 the vicinity of Copenhagen, and one specimen from Horsens; the only 

 date noted is */?. 



Geographical distribution : — The species seems unknown north 

 of Denmark, but is recorded down into Styria.
