Anthocharis helemia. — I have about 100 specimens of this species, 

 all bat two from Bir Yakub. Specimens taken from January 20th to 

 about March 20th, are quite unmistakably first brood specimens, with 

 dark green, ground, and narrow .s/7r('77/-white bands on the apex of the 

 forewings (underside), and on the underside of the hindwings. These 

 specimens differ slightly from the form predominating in a series of 

 about 25 specimens of the first brood captured in Egypt from Novem- 

 ber to early February, in that the white bands and markings on the 

 underside of their hindwings are somewhat more extensive than is the 

 case with the Egyptian average. Two specimens taken at Kolonia on 

 March 8th, were small, with narrow bands and deeper green ground 

 colour on the underside hindwings. From March 15th to March 28th, 

 we had very mixed weather, some very hot days, and some very cold. 

 Specimens of belemia, taken from about March 21st to March 28th, 

 were of three forms. 



(a) The second brood form g. a. glauce or distincta, as the 



Palestine form has been named. 



(b) A form resembling the first brood in its upperside markings, 



and somewhat closer to it than to (jlauce on the underside, 

 but with more yellowish green ground on the underside 

 hindwings, dull white or slightly pearly bands thereon, of 

 the same general shape as in the first brood, but with less 

 well-defined edges, and sometimes invaded by yellowish- 

 green projections. 



(c) A few helemia of first brood form. 

 Form b was the most common. 



After March 28th, only g. a. (/lance {dutincta) occurred. The 

 conclusion I am inclined to draw is that this species is decidedly 

 susceptible to temperature changes in nature, and that what I have 

 called form b {intennedia is the obvious name, but it may be a noiiien 

 ■preoceupatuiii, as far as I know, for some belemia, aberration, or for 

 some form of a congeneric species) may be either a late emerged g. v. 

 belemia or an early g. a. glance. The " normal" sequence is : — 



belemia — (g. v.). 



■glance — (g. a.). 



I 

 belemia — (g. v.), etc., etc. 



But I feel pretty certain that in some cases 



belemia belemia belemia 



I or 1 or I 



belemia form b glauce 



i . I . i 



belemia belemia form b 



are the actual pedigrees. 



Anthocharis ausonia [belia : crameri) g. v. triangula and g. a. 

 melisanda. — The vernal form was not abundant at Bir Yakub between 

 January 30th and March 18th. I bred a fine g. a. melisanda from a 

 larva found on Biscutella, near our W/T station, which pupated March 

 30th, the butterfly emerging on April 10th. The vernal form was 

 frequent at Kolonia on March 8th at a height of circa 2,000 feet. 



Euchlo'e cardamines var. phoeiiissa. — Two males at Bir Yakub on 

 March 6th and March 10th. Three <? s at Kolonia, March 8th. On
