152 PIERIS BRASSIGE. 



pupse I obtained this summer from Plymouth, had this 

 spike.) The outline of the belly a gentle curve from 

 the head to the end of the wing-cases, where the tongue- 

 case projects free for 1 mm. (but not so prominently 

 as in the engraving, Plate II, fig. 2a; Mr. Buckler seems 

 to have been the first to notice this projection, no pre- 

 viously published figure shows it) ; thence the abdo- 

 men goes in a second and gentler curve to the tail ; 

 the anal spike flat, almost square, being made up of 

 the two outside ridges with a triangular piece between, 

 and set on the ventral surface with many short spines 

 curved at the tip and then spreading into broad edged 

 hooks. There are two or three varieties of colour, the 

 most common is very pale greenish-white ; the head 

 spike blue at the base and yellow at the tip ; dorsal 

 keel, shoulders, and spiracles yellow ; the whole skin 

 sparingly freckled with tiny black dots ; the dorsal 

 and subdorsal ridges marked with larger black spots, 

 and several of intermediate size set in patterns on the 

 sides ; the tip of proboscis blackish. Another variety 

 is bluish-green all over, with yellow ridges and spiracles, 

 with the black spots much smaller and fewer in number. 

 Another variety is mottled with the green and white 

 tints. These varieties were developed side by side in 

 the same cage. (J. H., 3, 11, 85.)

(See Mr. Buckler's brief notice at p. 19.) 



This was the first species I looked out for this year, 

 in order to obtain eggs, but the early flight was so 

 scanty in its numbers that I failed to catch an egg- 

 laying female; however, one must have visited my 

 garden, for after a good deal of searching I found five 

 larvao (and no more) during the first week in July •
