LA RENTW.-E—E UPITHECIA . 93 



■minute black dot ; this is followed by a slendei- transverse 

 curved brown line ; but the whole wing is more faintly barred 

 with similar lines. Body and legs grey-brown. 



Usually scarcely varying at all, or only a little in the depth 

 of colour of the transverse lines, but in the collection of 

 Dr. P. B. Mason is a specimen entirely pale ochreous without 

 either darker lines or greyer dusting. 



On the wing at the end of May and in June. 



Larva rather short and thick ; head yellowish, suffused with 

 purplish-red ; ground colour dull pale yellowish-green ; dorsal 

 line broad, uninterrupted, dull purplish-red, enlarged in the 

 middle of each segment into a somewhat pear-shaped blotch ; 

 subdorsal lines narrow, sinuous, dull purplish-red ; spiracular 

 lines very faintly yellow ; spiracles black ; dorsal and lateral 

 regions thinly sprinkled with slender j-ellowish hairs ; under- 

 surface naked, dull pale greenish-yellow ; the middle line 

 wanting, the subventral lines narrow, purplish-red. The dorsal 

 and subdorsal lines are sometimes merged, leaving the back 

 and sides suffused with purplish-red. (Rev. H. H. Crewe.) 



July and August, on the flowers of Melampyrum iiratense 

 and M. arvcmc. (Cow-wheat.) 



Pupa golden yellow, the abdominal segments and tip red. 

 In a slight cocoon on the surface of the ground, or in a dry 

 corolla-tube of the Mclampiiruta. (H. H. C). 



In this condition through the winter. 



The moth rests during the da}' among its food-plant near 

 the ground, but is very restless and easily disturbed, so as to 

 appear often to be flying by day of its own accord. The 

 natural flight, however, I think only takes place at dusk. 

 Apparently to be found in all woods and wooded heath lands 

 in which large patches of its food-plant, the common cow- 

 wheat, are growing, and known to occur thus in Kent, Sussex, 

 Surrey, Devon, Cornwall, Somerset, Wilts, Berks, Middlesex, 

 the Eastern Couuties, Gloucestershire, Herefordshire,
