 black; subcostal sclerite with bristles.

 L. caesar seems to be'less common in 

 Denmark than simulatrix; Copenhagen, 

 Hellerup, Charlottenlund, Dyrehaven, Sor- 

 genfri, Ørholm, at Sorø; on Falster; on

 borg and Hattenæs near Silkeborg; the dates are ^"/g — ^9- I have 

 bred it from a pupa found in the ground, the imago emerging on ^e- 

 Geographical distribution : — Widely distributed species, Europe 

 and down into Africa, and also known from Japan; towards the 

 north to northern Scandinavia; it is further recorded from North 

 America and Brazil, and from New Zealand and Australia, but 

 it must be rembered that the records, both for this and other species, 

 cannot be considered as fully sure. 



Remarks: The female is difficult to distinguish from simulatrix^ 

 but I think it may generally be know^n by the less broad frons and 

 the cheeks being not or only slightly broader than the orbits.
