cell, one below it, and one at the proximal margin; at the cell-end a streak-like spot, behind it a very indis- 

 tinct macular series, followed by irregular grey shades; before the border dark angular streaks. Expanse of 

 wings: 22 mm. Castro (Parana). 



griqua. L. griqua Schs. has olive-grey wings, dark discal streaks and a dark distal margin, in front of which 



the markings beneath show indistinctly through; fringes white, speckled grey. The under surface reddish- 

 yellow with an olive tinge, the spots black, bordered with an isabel-colour; a dark marginal line, small dark 

 grey marginal spots, the latter more distinct on the forewings; here there is a black spot at the cell-end, behind 

 it a series of larger black spots; on the hindwing 2 small basal spots at the proximal margin, then a row of 4 

 black spots, a light spot at the cell-end, behind them a row of 7 black spots, the third from the costal margin 

 being placed the farthest towards the distal margin. Expanse of wings: 20 mm. Castro (Parana). 



ruberroihei. L. rubcrrothei Weeks. Body above black, beneath white. Forewing above light brown-black, in 



the basal area black, marginal line and veins darker ; hindwing above like the forewing, at the border a series 

 of black spots margined with a light brown, the one above the lower submedian vein being the most prominent. 

 Forewing beneath light brown, in the basal half strewn with white scales; at the border there are lighter moon- 

 spots indicated; in the hindwing beneath the white scaling is extended over the whole surface of the wing. 

 Expanse of wings: 18 to 19 mm. — • Bolivia (Sicasica). Perhaps better to be placed to Itylos beside moza and 

 inconsficua. 



10. Genus : Cyaiiiris Dalm. 



The species of this genusaredistinguishedby much more delicate, comparatively somewhat broader wings 

 and longer, more pointed palpi projecting far beyond the frons; their hairing is longer, too, and not so dense. 



ladon. C. ladon Cr. (= pseudargiolus Bsd. and Lee, argiolus Smith and Ahb., intermedia Sireck.) (144 h) 



is an extremely variable species being most widely distributed from Alasca and Anticosti to Panama. Above 



delicately milky blue with a slight violet tinge, on the hindwings almost whitish, in the ? above very broadly 



margined with black, often also on the forewings brightened up by whitish towards the margin. This is the 



typical summer-form , the under surface of which is white with small fine, black-grey punctiform spots. — - In 



early spring several forms fly together, which are generally somewhat smaller and exhibit beneath more diffuse 



lucia. and confluent macular markings, such as : lucia Ky. (144 h) with a brown spot in the disc of the hindwing beneath ; 



marginata. — marginata Ediv. (144 h) with broad, biown-grey margins beneath. — In contrast with it: f. violacea Edw. 



vtolacea. j- j^^ j^^ j-,j^g ^ clear and not confluent marking beneath. — In West Virginia and Colorado there flies a form 



nigra, that is quite black above: nigra Edw. (144 i). — f. cinerea Edw. may be a transition to it. ■ — f. arizonensis Edvj. 



cmerea. has in the $ considerably broader margins of the wings, the colouring being paler. — f . neglecta Edtv. is another 



neglecfa. form flying in summer with a much more promment and clearer marking beneath and of a smaller size. — In 



piasiis. South Arizona f. piasus Bsd. flies with a much darker violet-blue, unmarked colouring above; beneath the 



echo, spots are more indistinct. — f . echo Edw. is a large, quite pale, almost grey-white form from South California. — 



gozora. f. gozora Bsd. (144 i) is the southernmost form from Mexico and Central America to Panama; it is above of 



a deeper, more lilac colour with white discal spots between the median veins of the forewings, and a broad white, 



grey-veined distal half of the costal area of the hindwing. — The larva is very polyphagous. 



11. Genus: Everes Hbn. 



Distinguished by anastomosis of the uppermost subcostal vein with the costal vein. The wings are 

 narrower, the palpi slender and pointed, the two first joints covered with dense, soft, porrect hair. 



amynhda. E. amytltula Bsd. (144 i). This and the following species are both extremely alike and have, therefore, 



led to disagreements of opinion. We here state their general differences, according to the excellent examina- 

 tions of Bethune-B.aker, by which they are easily discernible, as there are no absolutely sure marks 

 to be stated. Amyntula is generally much larger, with decidedly broader wings, with a sharper apex and 

 a straighter margin. Above the marginal line is fine, black. The under surface is whitish, the spots of 

 the forewings short diffuse spots, scarcely encircled by white, the submarginal sjjots obsolete, also on the 

 herrii. hindwings all the spots are generally more obsolete. — • In f. herrii Grinnell which, however, coincides 

 with Boisdxjval's type according to Bakee, the black border of the wings is broader, the marking beneath 

 much more intense, and on the hindwing there are only two small orange spots at the margin instead 

 of the usual 5. Pacific States. Of this species only one generation is known. The larva lives on Astragalus. 



comyntas. E. comytltas Godt. (144 i) is generally smaller, with narrower, rounder wings, with a bent distal 



margin. Above the margmal line is broader, more brown-black. The under surface is decidedly greyer, the
