NOTES AND OBSERVATIONS. 321 



19th, one male attracted. 20th, none seen, but I was away for part 

 of the day. 21st, one male attracted. 22nd, four males assembled. 

 23rd, one male attracted; after this date none were seen, and the 

 females were all dead by the 29th. 



The conclusions I arrive at from above are, that the attractiveness 

 of the female reaches its zenith on the day after emergence, and lasts 

 in some degree for a week afterwards. The experiments of July 13th 

 and 17th are apparently contradictory ; I can only assume that the 

 single female on the first date was not " calling " ; this possibility I 

 minimised later on by using several females. — A. U. Battley ; Kings-

National Collection of British Lepidoptera. — Mr. Louis B. Prout 

 has recently contributed six specimens of Tephrochjstis {Eupithecia) 

 jasioneata reared by him from larvae obtained in North Devonshire. It 

 may be noted here that the Museum series of several British species 

 in this section are sadly in need of improvement, and this is more par- 

 ticularly tbe case with the following : — T. campanulata, T. munitata, 

 T. trisiynaria, T. constrictata, T, subciliata, T. piisillatct, T. exiguata, T. 

 irrirfuata, T. insiijnata {= consvjnata), T. fraxinata, T. helveticaria, 

 Chloroclystis coionata, C. rec.tangulata, and C. debiliata. Scotch and 

 North English forms of T. satymta, T. sobrinata, T. nannta, and 

 Gymnocelis puniilatti, would be exceedingly useful. Fresh Southern 

 specimens of T. venosata are also desirable. 



Description of a Variety of the Larva of Calocampa vetusta. — 

 On the night of June 11th last, I was surprised at taking a female 

 Calocampa at sugar, but she was in such bad condition I could not 

 distinguish which of the species it was. Both occur here, vetusta being 

 rather the more common of the two. She was kept in a chip-box, and 

 in the course of a week (^posited about three dozen eggs. These 

 hatched on June 21th, and the larvae fed up very rapidly on knot-grass, 

 and by July 21th were all full-grown, and were as fine and healthy- 

 looking lot of larvae as I have ever seen. But they puzzled me exceed- 

 ingly, for they in no way resembled the figures of either species as 

 represented in Buckler's plates. However, on Sept. 29th, the first 

 moth (a fine vetusta) emerged, and subsequently five others, three of 

 them being cripples ; and these were all I bred — rather a poor per- 

 centage out of thirty-one larvae. The following is a description of the 

 full-grown larva : — Head pinkish olive-green ; second segment the 

 same colour, with a dark transverse olive-green stripe across the 

 anterior part ; dorsal stripe conspicuous and pale lemon-yellow, or 

 pinkish yellow ; below the dorsal stripe comes a broad very dark, 

 almost black, olive-green stripe, having a soft velvety appearance, and 

 near the lower edge of this upon each segment are three conspicuous 

 white dots arranged in an obtuse angle ; this stripe is bordered below 

 by a narrow lemon-yellow line, followed by a broad greenish olive 

 stripe, which is gradually clouded towards its lower edge, where it 

 becomes an intense dark olive-green, and in this the minute orange 

 spiracles are seated ; below the spiracles there is a broad lemon-yellow 

 stripe ; the under surface and claspers are pale olive-green. It is an
