170 BRITISH BUTTERFLIES. 



by their angles only, into a continuous angular belt ; three of these patches, of 

 nearly equal size, but the middle one usually the largest, lie in a straight line 

 parallel to the longer axis of the wing, situated one each in the subcostal and 

 subcosto-median interspaces ; the last patch, not much larger than the second, 

 is composed of three confluent spots in the median and medio-submedian 

 interspaces, as far from the outer border as the second patch, the medio- 

 submedian spot further removed from the border than the rest ; the ground 

 colour of the wing is a greenish -griseous, and the spots are narrowly edged 

 exteriorly and interiorly with blackish. The markings of the ? s are similar, 

 except that they are usually a little larger and more obviously continuous, often 

 sending out on the exterior border little shoots of white along the nervures. 

 Winnipeg specimens of P. Manitoba seem to approach this species closely in the 

 markings of the wings. In the genital armature the upper organ is bent at right 

 angles in the middle and scarcely rounded, deeply sulcated posteriorly above along 

 the middle ; hook almost three-fourths the length of the centrum, straight, 

 moderately stout at the base, as seen from above, where it tapers rapidly, after- 

 wards slender and gently tapering ; lateral arms slender, gently tapering, nearly 

 straight, but little separated at the base from the hook, upturned at the tip to meet 

 the hook, which they slightly exceed in length. Clasps rather small, twice as 

 long as broad, not extending nearly so far back as the upper organ, narrowing pretty 

 regularly from the base, the upper margin incurved and slightly deflexed, the 

 posterior border rounded and protuberant ; the preapical tooth is longer than the 

 apical, very slender and curved, like the apical, a little forward; they are separated 

 from each other by a deep, rather wide, rounded excision ; the apical tooth is 

 supported by a serratulate lamina, which is the continuation of its inner anterior 

 edge, and which terminates by a conspicuous serratulate denticle opposite the 

 posterior edge of the preapical tooth. It has been taken in Colorado by Mr. Mead, 

 on the mountains about the South Park and in the Park itself. Mr. W. H. 

 Edwards has also sent me specimens from Nevada, California and Oregon, the last 

 collected by Dr. Gabb (Scudder). 



f. var. laurentina, Lyman, "Can. Ent.," xxiv., pp. 57-59 (1892); Dyar, " List 

 Nth. Amer. Lep.," p. 50 (1902). — Very uniform in colour ; the outer third of the 

 underside of the forewings and the whole of the underside of the hindwings with 

 the exception of the inner margin and hind angle, of a dark brown colour, though 

 occasionally with a slightly greenish tinge. Cacouna, Riviere du Loup, Metes, 

 Gaspe (Lyman). 



v. var. as siniboia, Lyman, " Can. Ent.," xxiv., pp. 57-59 (1892) ; Dyar, " List 

 Nth. Amer. Lep.," p. 50 (1902). — Differs from Manitoba of the Lower St. Lawrence 

 (i.e., var. laurentina) in that those parts of the underside which are brown in the 

 latter are of a very pale greenish-yellow, or yellowish-green, in the Kegina form, 

 but it also differs somewhat above, in that the c? s are usually of a yellower tone, 

 while the brown of the ? is decidedly darker and the spots of the forewings 

 decidedly lighter (some of them being almost white) than in the eastern specimens.

0. var. Manitoboides, Fletch., " Rept. Ent. Soc. Ont.," pp. 19, 86 (1888) ; 

 Dyar, " List. Nth. Amer. Lep.," p. 50 (1902). — This active skipper .... 

 belongs to the comma group of the genus PampJiila , and bears a somewhat close 

 resemblance to P. Manitoba, for which reason we call it manitoboides. It occurs, 

 however, six weeks sooner at Nepigon, than an insect I take to be true Manitoba. 

 As I do not wish to cause confusion by naming what may prove to be a described 

 species, I refrain from further describing the perfect insect, but give below some 

 notes on the egg and the larva after the third moult, and on the appearance of the 

 young larva in the first two stages. Egg. — Five eggs were obtained upon the 

 grass Danthonia spicata. These were laid upon the green leaves and were large 

 and showy, of a dull dead white, and of the same shape as those of P. hobomok. 

 Under the microscope the shell presents a surprising appearance, for it is covered 

 all over with threads and much resembles a piece of ordinary printing-paper under 

 a magnifying-glass. The shell of the empty egg is very thick, and it is with 

 difficulty that the pentagonal and hexagonal cells on the surface can be made out. 

 Eggs laid July 10th hatched upon 25th. There was no mottling with pink as in 

 P. cernes, and the only indication that the eggs were good was the gradually 

 darkening head of the young larva which showed through the thick shell. Larva. — 

 The newly-hatched caterpillar is of a much yellower shade of cream-colour than 

 either P. rcrncs, mystic or hobomok. The head, thoracic shield and first thoracic 

 feet, black. The whole body covered with knobbed hairs. Unluckily at the time
