Male. TJiis species is similar to the foregoing. Head coloured in 

 che same way, but frons less widening downwards, the inner eye- 

 margins less oblique, and thus the cheeks much narrower, scarcely 

 half as broad as the eye, and sparingly haired in the wliole breadth; 

 jowls also narrower, about half the height of the eye, and with small 

 hairs, only bristly hairs quite below. Antennæ with the two basal 

 joints red, second joint very slightly longer than third and with 

 stronger bristles on the front side. Thorax less pruinose and thus more 

 shining, with the stripes only slightly visible. Scutellum darker to 

 black. Abdomen similarly coloured and bristled as in nigricornis, 

 but less whitish pruinose. Fifth sternite much more deeply excised, 

 and thus the lamellæ longer, they are also of another shape, the lower 

 posterior angle drawn out into an upwards curved spine-Iike process. 

 Genitalia as in nigricornis., arms of lower forceps a little longer ver- 

 tically, likewise inwardly going out in a curved hook. Legs and wings 

 as in nigricornis, but tibiæ generally black. Squamulæ white. Halteres 

 brownish. 



Female. Similar, with the same differences as in nigricornis. 



Length 11 — 13 mm. 



P. ferina occurs in the same way as the foregoing, but is much 

 less common in Denmark and has only been taken at Tisvilde and 

 in Høbjerg Skov at Aarhus (Weis, Kryger, the author); the dates 

 are in July. One specimen is bred from Arctia aulica (Weis). The 

 species is besides known from Lasiocampa trifolii and Parasemia plan- 

 taginis. — I have examined a specimen sent from Zetterstedt to Stæger. 



Geographical distribution: — All Europe; towards the north 

 to middle Sweden.
