SCIENCE- GOSSIP. 



Ground colour much whiter and more opaque than 

 in /'. hippia, or any of its vars. Above, markings 

 more intensely black. F.w. with a distinct black 

 discoidal spot ; h.w. with the nervures broadly 

 veined with grey, owing to the markings of u.s. 

 appearing through. Often a distinct black discoidal 

 spot. U.S. f.w. white nervures narrowly black, with 

 a distinct discoidal spot. Ape.\ bright ochre-yellow, 

 which colour extends along the costa between it and 

 the subcostal nervure. H.w. Ground colour bright 

 ochre-yellow of a uniform tint, except a faint indica- 

 tion of submarginal lighter patches ; nervures ver}' 

 broadly lined with black. The pattern and colora- 

 tion of h.w. w.s. is very similar to that of ill. peloi-ia.

3. P. bieti Oberth. R. H. p. uS. 

 50-55 mm. 



About the size of the last species. F.w. have all 

 the nervures strong and broad, marked with black, 

 and the white ground colour is more or less streaked 

 with black shading. H.w. have the nervures marked 

 with black throughout their whole length, except the 

 .six internal ones, which are only marked at their 

 extremities. Fringes of all the wings black. U.S. 

 f.w. with strongly marked neuration. Ground 

 colour tinged with yellowish along costa and ou.-mar. 

 H.w. strongly marked with broad black veins, 

 ground colour yellowish.

41— 43 mm. 



Smaller than P. bieti. F.w. with a sub-marginal 

 blackish band, and black rays reaching from it to the 

 costa. Nervures forming discoidal cell strongly 

 black, as also the sub-costals ; the rest of the neura- 

 tion less conspicuous. H.w. without markings, 

 except a faint costal spot, and some shading along 

 the course of the nervures ; those nearest the costa, 

 however, are marked with black at their extremities. 

 Bases of all the wings narrowly black. U.S. much 

 as in P. kreitneri. H.w. with the ground colour 

 uniformly light yellow. The ■ nervures are marked 

 broadly black. Head, thorax, and abdomen black, 

 as also the antennae, which have the clubs'somewhat 

 more rounded than in the preceding species.

38—43 mm. 



Wings white. F.w. with a black ante-marg. band 

 and black rays reaching to the costa, as in P. davidis. 

 A black elongated spot at extremity of disc. cell. 

 H.\v. luuch as in the last species, but with a faintly 

 marked disc, spot or streak of black. Wings nar- 

 rowly black at base. Fringes black. U.S. f.w. as 

 above, but with Ijlack markings intensified. H.w. 

 ground colour yellowish-white, with nervures marked 

 black. A narrows black, wavy band continued as 

 far as the internal nervure. Head, thorax, and abdo- 



men black. Antennae black, with o\"ate clubs as in 

 the last species. 



Hab. North .Persia, Central .Vsia, Turkestan. W. 

 Said to occur in North California. 



a. var. ilhuuina Grum. The black markings arc 

 more intense and the lines of neuration more broadl)' 

 marked. Hae. N. Persia, Alai, Turkestan. 



b. var. alle/isis Stgr. A small form from the Altai. 

 This species is usually placed between P. caUidiie 



and P. daplidice. but it seems to me that its 

 proper place is in the present group of the genus, in 

 spite of the central band on the u.s. h.w.

P. potanini Alph. 



35—38 mm. 



Fore wing white, with three or four black streaks 

 near apex, and a rectangular black sjDOt at end of disc, 

 cell. Base narrowly black. H.w. white, with light 

 grey streaks along the nervures. A long and narrow 

 black disc, spot ; base broadly blackish. U.S. f.w. 

 as above, but apices ochre-yellow with brown veining. 

 H. w. ochre-yellow, with strongly-marked brown veins, 

 the nervures appearing as a light-coloured line in the 

 centre of each streak. Head and pro-thorax covered 

 with brownish-grey hairs. Rest of thorax and ab- 

 domen black. Antennae with a distinct ovate black 

 club ; their shafts are ringed with white. ( (J only 

 described here. )

Ground colour of all the wings white in both 

 sexes. F.w. in $ with a narrow black spot at the 

 extremity of the discoidal cell. Ape'x and ou. marg. 

 black to about half-way ; on this black patch are six 

 white oblong spots between the nervures. H.w. 

 with a marginal border of narrow black chevron- 

 like markings. Neuration distinct, but not black. 

 Fringes black. Head, thorax, and abdomen black, 

 with whitish hairs. Antennae greyish-black, not 

 ringed. $ resembles the $ in the general character 

 of the markings ; but the black spots and borders 

 are much wider, and with very little white mixed 

 with them, recalling at first sight the appearance of 

 a species of the genus Melanargia. U.S. as above, 

 but apices and costa of f.w. and almost all the 

 ground colour of the h.w. tinged with yellow. 

 Neuration marked rather broadly black on h.w.
