THE ENTOMOLOGIST ^^ RECORD. 



imago appeared, whilst some of the larvae were still feeding, and the 

 insects have continued emerging occasionally till October 19th, when, 

 there being two days of much warmer weather (nearly 60*^), a ^ and ? 

 came out. These I paired, and ova were laid on October 21st and 22nd. 

 The batch is a fairly large one, made-up, probably, of about 150. The 

 ova are rather bright green, with slight bluish tinge. The average 

 size is •Qib'd mm. vertical axis, and -488 mm. transverse axis. Fifteen'-'- 

 pupae of these broods, 2nd generation {a), are going over. On August 

 80th, I had previously paired two hybrids of the 2nd generation (.7), 

 and ova were laid on September 3rd. On August 31st, I again paired 

 two more, which produced ova on September 4th. The ova from both 

 these batches were yellowish-green, and the average size was -693 mm. 

 vertical axis, and -471 mm. transverse axis. The first batch was in- 

 fertile, the second hatched on September 18th-19th, and the larvre are 

 feeding in a warm room at the present time (October 25th), a few 

 being in the 2nd stage, but most in the 3rd. Other hybrids were also 

 paired, with the following results : —
