458 LÉPIDOPTÉROLOGIE COMPARÉE 



The wing cases in bidovecï are coarser than those in hirtaria 

 and differ greatly in shape from them. In hirtaria, they are much 

 longer, whilst in buloveci the extrême angle is much more pointed 

 and the termen and inner margin are straight and enclose an 

 angle of 120°. In hirtaria, there is no angle, just a broad swee- 

 ping curve. The cases of the legs, although flatter, arc not so 

 neat as in hirtaria; nor are the antennal cases so full and whilst 

 slightly broader, they are not so smooth. The pectinations are 

 clearly marked. The spiracles are much larger than in hirtaria 

 and are not only in a deeper dépression, but are nearer the anterior 

 edge of the segments, just as in grœraria. 



Their shape, too, differs from those of hirtaria pupae; instead 

 of being a broad regular oval, they follow grœcaria in being 

 narrow and more pointed below. 



Lying over of pupas. 



Out of fifty one pupas obtained this year only one individual 

 is lying over. The proportion therefore, is the same as in English 

 hirtaria. Of thirty six grœcaria pupae, obtained in 190g, two came 

 out in 1910. three emerged in 191 1, and four (2 cf + 2 q) in the 

 spring of the présent year. 



Imago. 



The imago has not been bred *, but one extracted from the pupa 

 case much resembled one of the large harrisoni with ail the suffu- 

 sions suppressed. The ground colour is very pale yellow ochreous 

 and the lines are much as in denhami (Genitalia ûgured on 

 PI. D, No. 19). 



* Since the above was written imagines hâve emerged at irregular intervais 

 during December 1912, January and February 1913.
