DoNiSTHORPE, however, said that he could not accept this 

 identification on account of the male characters. 



Varieties of Abraxas geossulariata. — Mr. G. T. Porritt 

 exhibited forms of Abraxas grossulariata bi'ed from wild 

 Huddersfield larvae during the past year, including (a) a 

 pale female in which the usual yellow was entirely replaced by 

 olive-green ; (b) a very pretty $ with broad orange band ; and 

 (c) two males of the var. varleyata, showing how wide a range 

 of variation there is even in the variety ; one of the specimens 

 having an inner row of white rays, in addition to the usual 

 outer row, a very rare form. 



Mr. L. W. Newman also exhibited an extreme form of A. var. 

 varleyata, the whole of the fore-wings being coal-black, and 

 only a very narrow white band on hind-wings. The specimen 

 was bred as part of a second brood, November 24th, from 

 typical parents, the former generation being varleyata ? x 

 type $. 



Parallel variation of Heliconius forms. — Mr. W. J. 

 Kaye exhibited a fine series of Heliconius species from Mapiri 

 River, N. Bolivia, to show the close parallel variation between 

 the very variable forms of melpomene with the equally variable 

 forms of 2^hylUs. These two species belonged respectively to 

 the two great primary divisions of the Heliconius as deter- 

 mined by Riffarth. The forms exhibited were melpomene 

 amandus, Gr.-Sm., onelpomene var. et ab. aphrodite, Stgr., and 

 melpomene penelope ab. penelamanda, Stgr., the pliyllxs forms 

 being Phyllis pliyllis, Fab., phyllis var. et ab. phyllis, Gr.-Sm., 

 phyllis var. et ab. amatus, Stgr., and phyllis anacreon, 

 Gr.-Sm. Notwithstanding the splendid recent work on the 

 Heliconius b»y Weymer, Riffarth and Stichel, it was manifestly 

 impossible to decide without breeding what were good species 

 and what were only aberrations. 



The use of the term subspecies as employed by Riffarth 

 and Stichel was very ambiguous and did not convey a 

 geographical meaning as employed by Rothschild and Jordan 

 in their more recent work. It was contended that two or 

 more subspecies could not inhabit the same locality, and that 

 either the forms were distinct species or aberrations. As 

 regarding the two species exhibited, Mr. Kaye was of opinion
