416 BKITISH BUTTERFLIES. 



Yonkers (Howe) and Cowansville (Fyles). Hulst notes, that, between 

 April 17th and May 19th, he captured 118 males and 31 females ; the 

 first example was a male marginata, on April 17th ; on the 19th he 

 took 1 marginata male, and 1 riolacea female ; on the 22nd, 3 lucia, 

 two of which displayed very large dark patches on the underside 

 of hindwings, 7 marginata, and 4 violacea ; on the 24th, 2 lucia, 11 

 marginata and 7 violacea ; on May 1st, 6 lucia, 22 marginata, 23 violacea; 

 on May 16th, 4 lucia, 7 marginata, and 3 riolacea, etc. He further 

 notes that, on one day in the spring of 1881, he captured 41 examples, 

 of which 8 are lucia, all but three having the dark underside patch 

 of large size, 24 are marginata, and 9 violacea. On the whole, at 

 Brooklyn, lucia is common, marginata comprises the bulk of the speci- 

 mens, whilst violacea is not infrequent. Fyles observes that, at 

 Cowansville, he captured on May 22nd, 2 marginata, on May 27th, 

 2 marginata, on May 31st, 1 marginata, on June 2nd, 4 marginata and 

 2 lucia, on June 12th 1 lucia.

 ii., Lye. pi. ii., fig. 24, p. 10 (1884). — This is the figure of an aberrant ? marginata 

 taken by Hulst at Brooklyn. The left wings are fairly normal; the marginal band 

 of the forewings somewhat narrow, on the hindwings wanting; the right forewing, 

 however, has the marginal band reduced to a small patch or two inside the slender 

 black marginal line, the right hindwing similar to the left. One suspects at first 

 sight some element of gynandromorphism in the markings.

 Pseudargiolus, Bdv. and Le Conte, "Lep. Am. -Sept.," pi. xxxvi., fig. 3 (1833) 

 (teste Scudder). — Male. — Expands from -9in. to l-2in. Upperside usually deep 

 glossy violet-blue, but sometimes with a pink tinge ; costal margin of primaries 

 silvery, hind margins of both wings edged by a black line, which is expanded on the 

 apical half of primaries into a border ; on this part of the wing the fringe is black, 

 but on the lower half and on secondaries it is white, with black at the ends of the 

 nervules ; occasionally on secondaries it is entirely white, in many cases the black 

 marginal line tarns the anal angle and there thickens, so as to make a noticeable 

 spot, as often there is a black elongated spot at the outer angle, and sometimes 

 5 or 6 dots between these along the margin. Underside of both wings greyish- 

 white, of uniform colour entirely to the margin, primaries have a dark grey discal 

 streak, a submarginal transverse row of 6 rather broad, mostly elongated, black 

 spots, the first next costa in advance of the line, the others parallel to the margin, 

 the 3rd, 4th, 5th standing obliquely; along the margin a row of 6 points, often 

 partly obsolete, each preceded by a distinct dark grey crescent, these hist uniting 

 so as to make a crenated line. Secondaries have a discal streak ; three black 

 spots in a row halfway between the streak and base, one being on either margin ; 

 the third midway between them ; a transverse row of 8 clear black spots across 

 the disc, the two next costa largest, much in advance of the others, and over against 

 the streak, with which and the 8th spot they form a direct line ; the 3rd is separated 

 from the 2nd by a considerable space, the 4th is turned obliquely, the 7th is long and 

 lunular and back of the line, the 8th very near the margin, elongate ; along the margin 

 is a row of 6 blackish dots, palest at outer angle, that next anal angle double, the 

 one preceding largest and conspicuous, each spot surmounted by a crescent 

 as on primaries. Body above blue, beneath white ; palpi white ; antenna 1 black, 

 ringed with white, club black, tipped with ferruginous. From upwards of 100 

 males taken on the Kanawha River, March and April, 1865, and April, 1866. 

 Female. — Paler and dull-coloured, the hindmargin and apex of primaries with a 

 broad blackish border; costa of both wings a little obscured by same colour. 

 From two females taken near Philadelphia. These resemble the ? of lucia on the 

 upperside, but are unicoloured below. I have myself taken but one ? of this 

 species, and this is abnormal, resembling the male almost exactly in colour as 

 well as markings, the only difference being that the disc of secondaries is paler
