816 LYCAENA. By Dr. M. Deafdt. 



antiacis. L. aiitiacis Bsd. (= polyphemus Bsd., orcus Ediv.) (144 c) is in the ^ quite light violet-blue with 



a iicarrow black border, the ? 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 xerxes, but they are thickly 

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



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

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

 darker grey-brown under surface. 



couperii. L. couperii Grf. (= pembina Streck. nee Edw., 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 antiacis white. 



lygdamas. L. lygdamas DbJ. (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 with 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, without 

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



4. Subgenus: Phaedrotes Snidd. 



sagitiigera. L. sagittigera Fldr. (= catalina Reak., 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. (144d) 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 Scudd. 



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 Hhii. 



podarre. L. podarce Fldr. (= tehama Beak.] cilia Behr, nestos Bsd., orbitulus Streck.) (144 e). The ^ 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 the hindwing. In the darker $ the cell-spot of the forewing is above surrounded by 

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



ctquilo. L. aquilo Bsd. (= franklinii Cwrtis) (144e) replaces the eastern orbitulus in, Ai'ctic 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. 



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



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 marginal 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 sniall orange spots. Pacific States. 



ghuicon. L. glaucon 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 spo-tted black. Colorado, California. 



hatloUles. 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 sjjots. Beneath brown- 

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