Tliis is tlie tyi e of the genus and occurs lliiouixliout 

 Europe, iilso langiufi; as far as Eastern Siberia. Tlmugli 

 the thorax and median segment are usually red in the female, 

 much variation exi.sts in this respect, the fenuile sometiines 

 liaving the thorax and median segment wholly black.

Evidently very closely allied to ariadne, having the same 

 nei vure at the base of tiie (ir.-it cubital cell.

I doubt if this is more than a geographical race of the 

 Indian /Jonwnotus ariadne, Cam., but the spines at tlie apical 

 angles of the median segment are distinctly longer and more 

 acute in Australum specimens.

This differs from exulo.ns in the c dour of the wings and 

 nei vure.«, and in the niucli shorter and blunter spines at the 

 apical angles of the median segment. 



Both 8|)ecies aiid also //. ariadne, C^im., have the submedian 

 cell of the fore wing as long as the median, not a little 

 shorter as in the European H. sanguinolentus, Fabr. The 

 first cubital cell is also pointed at ihe lase, projecting towards 

 the base of the wing a little beyond the ba.sal nervure, in this 

 also differing from sanguinolentus.

This may prove to be a seasonal funn of cjculans.
