 Auditions by Sir George Hampson, Bart., b.a., f.e.s., &c. 



Part XVI. 



( Continued from page 326, Vol. XV.) 



Family NOCTUIDJ1. 



Sub-family AGROTINM. 



Genus Chloridea, Westw. 



1G01. C. armigera, Hiibn. 



Sikhim and Bhutan up to 6,000 feet. A very common insect at the 

 lower elevations. The larva is most destructive to flower buds and 

 seeds, boring into them. Considerable variation in colour of the 

 markings occurs among larvae ; some taken feeding on the seed-bearing 

 heads of sunflowers were greenish with a darker dorsal and paler 

 lateral line. I have specimens of the perfect insect taken in March, April, 

 May, June, July and August. 



1601 Pt. C. assulta, Guen. 



Sikhim and Bhutan, 1800-2500 feet. The form separata, Wlk., 

 occurs, but not commonly at low elevations. The species or rather the 

 form of it just mentioned was included under Heliothis armigcra, Hiibn., 

 in the Moths of India. 



Genus Timora, Wlk. 

 1615. T. irrorata, Moore. 



Sikhim, 1,800 feet. I have eight specimens taken by me at light at 

 Punkabaree in October. The forewing of this insect almost exactly 

 resembles that of Adisura atkinsoni, Moore, but the hindwing of the 

 latter species is always more or less marked with black upon the outer 

 margin, and insects of the Genus Adisura do not possess the strong 

 torminal spine to the tibia of the foreleg. 



T. albicilia, Hmpsn. 



Sikhim, 3,000 feet. I took three specimens of this at Bad am tarn, 

 bui have not taken it elsewhere. The type is in the British Museum.
