from the middle to the end of April in the centre. The adults of the 

 first generation usually appear about the 20th March in the south, the 

 1st April in the centre and 10th April in the north. 



The second generation rarely appears in sufficient numbers to cause 

 much damage, but there have been outbreaks at the end of July and 

 in August, and if there is a third generation, outbreaks occur in early 

 September. 



During nearly every outbreak of this pest there is also an abundance 

 of Lycophotia {Peridroma) margaritosa, a cutwoiTn that feeds readily 

 on clover and lucerne, causing considerable damage, which is often 

 attributed to C. unipuncta.

One of the most important natural enemies of the Noctuid, Achaea 

 Janata, Dru. {melicerta, Dru.), in India, is a Braconid, Microplitis 

 ophiusae, sp. n. Other parasites are the Ichneumonids, Edrisa 

 pilicornis. Cam., Paniscus lineatus, Br., Microtoridea lissonota, Vier., 

 Zamesochorus orientalis, Vier., and the Eulophid, Tetrastichus ophiusae. 

 Craw. Some of these, especially Zamesochorus, may prove to be 

 hyperparasitic on Microplitis. 



M. ophiusae appears to be closely alHed to M. eusirus, Lyle [R. A.E., 

 A, ix, 558].
