 long, of about equal length, proboscis slender with small labella. 

 Palpi thin, thread-like. Antennæ inserted a little below middle of the 

 eye, not reaching the end of epistoma, third joint slightly or almost 

 not longer than second; arista short-hairy, second joint quite slightly 

 elongated. Thorax longish rectangular; three postsutural dorsocen- 

 trals and two præ- and only præscutellar postsutural acrostichals 

 or these latter wanting; no præsutural intraalar bristle; one post- 

 humeral bristles, Scutellum with three marginal bristles on each side, 

 the apical a little small, crossing. Three sternopleural bristles. Ptero- 

 pleura above with small hairs and a small bristle. Abdomen elongated 

 conical, excavation on second segment reaching hind margin or nearly, 

 the hind margin of the segment roundly excised in the middle; there

The development is not known, at all events not with certainty, 

 but riifomaculatus is thought to have been bred from Arctia hebe. 

 This species is known to belong to Pantel's group 5. Hartig (Jahresber. 

 tiber die Fortschr. d. Forstwiss. im Jahre 1836 und 37, 1837, 281, 6) 

 says about it: "Nach Bouché aus Eulen und Spinnerraupen". 



Of the genus 6 European species are recorded, two occur in Den- 

 mark.
