816 LYCAENA. By Dr. M. Dravot. 



antiaeis. L, aiitiacis Bsd. (= polyphemus Bsd., orcus Edw.) (144 c) is in the (J quite light violet-blue with 



a narrow black border, the 2 dull brown-grey, with a blue tinge towards the base, beneath light grey, on the 

 hindwings somewhat more brownish; the spots show the same arrangement as in xerzes, but they are thickly 

 pupilled black, particularly on the forewings; there are no submarginal spots at all. California, Nevada, and 



mertila. Arizona. — The form: mertila Edw. (144 d) has less thickly black-pupilled spots and more intensely greenish 

 heJirii. bases of the hindwings, whereby it comes nearer to xerxes. — f. behrii Ediv. (144 c) is distinguished by its much 

 darker grey-brown under surface. 



couperii. L. coupedi Grt. (= pembina Strech. nee Edtv., afra Edw.) (144 d) is perhaps only a northern form of 



the preceding from New Foundland and Labrador; above almost the same, beneath dark brown-grey, the spots 

 arranged the same, but nearly all white, only slightly black-pupilled, particularly on the hindwing. Fringes 

 grey-brown, in antiaeis white. 



lygdamas. L. lygdamas Dhl. (144 d) is considerably smaller, above much lighter silvery blue, in the $ darker, 



towards the margin smoky, with a dark cell-spot. The under surface is light brown \\iih. thick, black, white- 

 ringed spots arranged like in the preceding species and a pair of small spots in the middle of the cell on the 

 oro. forewing. Sonora, Atlantic States. — The form: oro Scudd. (144 d) is larger, beneath quite light grey, Avithout 

 a brown tint, towards the base somewhat bluish. It flies in Colorado, California and New Mexico. 



4. Subgenus: Phaedrotes Scudd. 



aagittigera. L. sagittigera Fldr. (= catalina Beak., lorquinii Behr, rhaea Bsd., viaca Edw., daunia Edw.) (144 d) 



is a most variable species, mostly rather light blue, towards the margin more or less dark smoky with white- 

 speckled fringes. Beneath grey-brown, dusted with a chalky white alternating more or less conspicuously 

 particularly on the hindwing in the cell and before the submarginal spots. In the Rocky Mountains and California. 



speciosa. L. speciosa Edw. (144 d) is a very small species, of a delicate light blue, in the $ broadly bordered 



with a brownish grey. Beneath so very much strewn with white that almost only the inner-marginal half of 

 the forewing remains brown; the spots of the hindwing are very small, the submarginal spots are almost entirely 

 absent. From South California. 



5. Subgenus: Philotes Smdd. 



sonorensis. L. sonorensis Fldr. (= regia Bsd.) (144 e) is unmistakable by the red-spotted, silvery blue forewings. 



Distributed from California to North Mexico. 



6. Subgenus: Agriades Hbn. 



podarce. L. podarce Fldr. (= tehama Beak., cilia Behr, nestos Bsd., orbitulus Streck.) (144 e). The <J is above 



grey-blue, towards the margin darkened, and in the disc lighter, here with dark cell-streaks, before the border of 

 the hindwing with darker, small lunae. The under surface is dull grey-brown with the usual small eye-spots 

 and a large white cell-spot of tlie hindwing. In the darker $ the cell-spot of the forewing is above surrounded by 

 reddish-yellow. At loftier altitudes of California, Nevada and Colorado. 



aquilo. L. aquilo Bsd. (= franklinii Curtis) (144 e) replaces the eastern orbitulus in Arctic America, like 



the following does in less northern latitudes. Very small and dark blue-grey, particularly also the under surface 

 very dark brown with large white, only feebly and finely black-pupilled spots. 



rusiica. L. rustica Edw. (144 f) is almost the same species as the preceding, and according to Couevoisier, 



the name has to replace the paleartic denomination of orbitulus Prun.; by one third larger, and lighter blue than 

 aquilo, beneath light grey with purely white spots. From Colorado and British America. 



7. Subgenus: Rusticus Hbn. 



enoptes. L. enoptes Bsd. (144 e). Above blue, the $ brown, more or less suffused with blue, with or without 



an orange margmal band of the hindwing. The fringes white-speckled. The under surface is light blue-grey 

 with the usual spots, between the submarginal spots of the hindwing small orange spots. Pacific States. 



glaucon. L. glaucotl Edw. (144 f) has a somewhat broader black border of the wings than enoptes, and on 



the hindwings there appear above dark marginal lunae. The under surface resembles that of the preceding, 

 and is perhaps on an average more strongly spotted black. Colorado, California. 



baiioides. L. battoides Behr (144 f) is of a more delicate and lighter blue than the preceding, with a distinctly 



diaphanous orange marginal band of the hindwing and before it small dark crescentiform spots. Beneath brown- 

 grey with much larger, more square spots arranged in the same way as in enoptes. California, Arizona, Colorado.
