Puhl. 11. I. 1921. LYCAENA. By Dr. M. Drattdt. 817 



L. Shasta Edw. (= zelmira Fldr., calchas Behr, niviuni Bsd., lupini Behr, niinnehaha ScMfW.) (144 f). .■<liastn. 

 Above violet-blue, in the $ extensively brown, with dark submarginal lunae, very distinct black cell-streaksi, 

 and in the $ with small orange marginal spots behind them. Beneath dirty grey with the usual rows of spots 

 and small orange marginal spots ; the distal submarginal row of spots is proximally silveiy blue-green. Pacific 

 States and Rocky Mountains. 



L. melissa Edw. (144 f) is on an average larger than the preceding, in the brown 2 above with broad »ii-!i.<isn. 

 orange marginal bands, behind which there are Ijlack marginal spots. Beneath light brownish grey with oblong 

 orange luarginal spots on both wings. From the Rocky Mountains. 



L. scudderi Edw. (144 f). The J does not differ above from vieli.^sa, the '^ is darker, the orange marginal scuddn-i. 

 bands reduced to narrow, small crescentiform spots on the hindwings, the under surface is whiter, the eye- 

 spots, orange marginal spots and small metallic spots all very much smaller. The laiva lives on Lu])ini and 

 other Papilionaceae. Atlantic States, common. 



L. lotis Linin. (144 f) is larger, the j* violet-blue with a very narrow black border, the $ above unico- Mi^- 

 lorously brown, beneath as light as the preceding, perhaps a shade more brownish, with particularly reduced 

 submarginal spots without any orange between. From California. 



L. acmon Dhl. d- Hew. (= antaegon Bsd.) (144g). Very easily recognizable by the broad orange annon. 

 marginal band of the hindwing in which there are black submarginal spots, both in the brown $ being dusted 

 blue towards the base, and in the lilac-blue .^. Beneath marked like melissn. only of a somewhat lighter tinge 

 and with a coherent orange band between the submarginal rows of spots. Pacific States and Rocky Mountains, 

 to the south as far as Mexico, where it flies in the surroundings of the capital. — In theform emigdionis Grinnell imiydionin. 

 {= melimona Wright) (144 g) the orange bands of the hindwings are above still broader and proximally faded. 

 — subsp. monticola Clem, is above more silvery blue, beneath marked with thicker spots on an ashy-grey moniicola. 

 ground strewn with bluish. The $ is above strewn with a much brighter blue as far as almost to the border, 

 the red band of the hindwing occupies almost one third of the hindwing; the under surface is more brown- 

 ish. From Pasadena (California). — f. neurona Skinner, described only according to female specimens, resembles neurona. 

 typical acmon from which it differs above by orange ribs terminating broader into the margin, also the costal 

 margin is sometimes orange. From San Bernardino (California). — f. clilorina Skinner {l^^ g) I can likewise Morina. 

 only take to be an aberrative $ of acmon. with a much broader orange border of the hindwing, which, however, 

 does not appear proximally faded as in evrigdionis. but distinct. California. 



L. aster Edw. (144 g, h) is smaller than the preceding, above light blue like eno'ptes, the % dull blue- a><kr. 

 grey, instead of the orange marginal band there are faint blue small lunae bordering on the black marginal 

 spots. Beneath very light, the spots small, the submarginal spots more or less obsolete without any orange 

 between. Known only from New Foundland. 



L, yukona Holl. has remained unknown to me, it may belong near here. The wings are above in yukona. 

 the (^ dark violet-blue, with a fine brown marginal line and white fringes, in the $ black-brown, towards the 

 base with a blue tinge. Beneath dark ashy-grey, towards the base dusted blue-grey, marked like the others; 

 a characteristic mark is the 6th spot of the postdiscal row, counted from the costal margin, being double on 

 both wings, only on the hindwing removed very far inward; between the 2 rows of marginal spots there 

 is no orange except the space between the median veins of the hindwing; the subterminal row consists of small 

 sagittate spots the points of which show towards the base. Expanse of wings: 22 to 24 mm. From North 

 East Alasca, captured between the 20th and 24th of July. 



L. annetta 3Iead. (144g). Above light blue; the 5 still much lighter, towards the margin almost whitish, anytrlta. 

 on the hindwings with small black marginal spots. Beneath coloured and maiked like .scudderi (144 f). Utah. 



L. anna Edw. (== cajona Beak., argyrotoxus Behr, philemon Bsd.) (144 h) resembles melis.sa (144 f) anna. 

 above, but it is considerably larger; also the under surface is extremely similar to that of melissa, but all the 

 spots somewhat smaller and finer, also the small orange marginal spots smaller. Pacific States. Colorado. 



L. cogina Schaiis. I am unable to judge whether this species and the 2 following, having remained coyina. 

 unknown to me in nature, belong to the real Lycaena or to one of the following genera. The description runs 

 as follows: In the t^ the forewings are lilac-white, towards the base strewn with black: the costal margm, apex 

 and distal margin are broadly grey-black; hindwings lilac-white, at the base strewn with black scales; costal 

 margin broadly dark grey; a black marginal line, dark marginal spots between the veins, and before them 

 dark triangular shades. Under surface grey-white with a dark marginal line and dark triangular margmal spots. 

 The forewings exhibit a dark spot at the cell-end, a postdiscal row of dark grey spots bordered with white, and 

 behind them dark diffuse spots between the veins, before the border a series of dark lunae. On the hindwings 

 the spots are bordered with a j)ure white; two dark costal-marginal spots, in the basal area 3 spots: one in the
