Orthorrhapha brachycera. 



what broAvnish pruinose, the incisures sometimes brownish. Abdomen 

 clothed with longish, yeliowish hairs, in the dorsal middle line with 

 black hairs which towards the end supersede the yellow hairs, so that 

 the last segments get quite or nearly quite black haired ; at the lateral 

 hind margins of the segments there are longer hairs, but there are no 

 real bristles. Venter clothed with long, yeliowish hairs, the last ven- 

 tral segments often with black hairs at the hind margins. Genitalia 

 black, the hairs black at the base, paler at the apex; the upper for- 

 ceps with a large excision at the apex, thus when il is closed there 

 is an elliptical opening in front and a nearly 

 circular opening behind; the median dorsal la- 

 mella is reddish; the ventral lamella black, not 

 shining. Legs black, tibiæ, except the tips, reddish, 

 tarsi reddish, the apex of the onter joints blackish, 

 the last joint nearly black. Goxæ greyish pruinose 

 with long, yeliowish hairs ; the short hairs on the 

 legs are yeliowish on the femora, black on the 

 tibiæ and tarsi; the usual dense pubescence on 

 the front and hind tibiæ is reddish. The front 

 femora and tibiæ have long, thin hairs ventrally, 

 and the middle tibiæ some few. The front 

 femora have densely placed spine-like bristles 

 ventrally near the base, the posterior femora 

 ventrally and on the front side, and the middle femora also some on 

 the posterior side near the apex; the tibiæ have some shorter, spine- 

 like bristles. The spine-like bristles are chiefly black, only on the front 

 side of the hind femora there is generally a row of pale ones. The 

 strong bristles on the tarsi are black. Wings milk-white at the base, 

 brownish on the apical half and along the front margin; veins brown. 

 Balteres whitish yellow.

 spots also present on the last segments; wings not milky but hyaline 

 at the base.

P. germanicus is not rare in Denmark though it cannot be termed 

 common; vicinity of Copenhagen, Brede, Odsherred, Tisvilde, Jægers- 

 pris, Hvalsø; on Møen; in Jutland at Mausing near Silkeborg and at 

 Bangsbo. My dates are ^'^/s— '-^/t. It occurs especially on fields, often 

 in the vicinity of woods, and it is often seen sitting on the leaves of 

 grass. Poulton 1. c. records it from England with Hoplia philatithus
