spots appear as more clearly prominent, white-ringed eye-spots, the submarginal fpots and all the spots of 

 the hindwing are always distinct. In southern specimens the blue colour increases at the bases of the wings, 

 in the $ above. The species is widely distributed from Canada to the .south through Mexico, Guatemala, Honduras, 

 Nicaragua as far as Costa Rica, in 3 or 4 generations. — The larva is brown or green, very variable, and lives 

 on the most different Papilionaceae. 



E, tulliola G. c£- S. (144i) is a very nuich deviating, small delicate species. Above light blue with lnUiula. 

 a Inoad, brown-grey distal margin of the forewing and a narrower one of the hindwing. Beneath light grey 

 with the usual postdiscal series of blackish, white-ringed eye-spots and cell-spot; in the middle of the cell there 

 is besides a double, black spot which is only single or may be entirely absent in specimens from more southern 

 habitats, and at the costal margin above the said spots and the di.scal streak there is one black, white-ringed 

 punctiform spot each; before the brownish-grey marginal triangles in the white ground a series of angular spots 

 appearing as a notched line. The hindwings are marked in the same way. Occuiring from Mexico through 

 Guatemala, Venezuela, Colombia as far as East and South Brazil. 



In addition we wish to state that two speceis, hitherto inserted in Everrs and reported to originate from ralifoinia: 

 DKiriica Rcak. and tejiia Reak. have been identified by Dr. SkinneR, on comparing tlie types, as the Chinese Euchrysops 

 cncjus rcsp. CafochryiiO)>s strabo. 



12. Genus: Heiuiargus Him. 



Scarcely different from the real Lycaeyia; the scaling is more delicate and thinner, the colouring mostly 

 a more lustreless violett-blue; beneath the hindwings exhibit at the anal angle 2 or 3 black, small eye-spots 

 being pupilled and encircled green silvery. 



H. isola Reak. (= alee Edw.) (144i, k). The (^ is above violet-blue, the v brown, towards the base l-^ola. 

 more or less tinged blue, on the hindwings in the anal area with 1 or 2 black marginal spots. The under surface 

 is ashy-grey, the hindwings mo.stly more brownish, on the forewing, with a postdiscal row of large black, white- 

 ringed spots, all the other spots except 2 black costal-marginal spots on the hindwing are small and brownish; 

 on the hindwing there are behind a whitish submarginal band 2 black anal spots with green-silvery pupils and 

 encircled by somewhat reddish-yellow, the proximal one being mostly divided into two very small ones. From 

 Texas to Mexico. • — nyagora Bsd. I can only take to be an insignificant form, in which the white submarginal nywjora. 

 band is absent on the darker under surface of the hindwing. 



H. gyas Edw. is very much alike, above lighter violet-blue, otherwise the same. Beneath light vyas. . 

 brown with a whitish hue, with the same markings, but without the whitish submarginal band, and the tMO 

 anal spots are plainly blackish. Arizona. Expanse of wings: 23 mm. 



H. cyna Ediv., based upon a $, has above on a purple blue ground a broadly darkened brown margin rytia. 

 and apex, and a fine discal streak; on the hindwing the anal spot is absent. The under surface is tawny, dusted 

 whitish, the large black spots on the forewings in the preceding are here brown, the two upper ones smaller 

 and placed inwards. Texas. Expanse of wings: 22 mm. 



H. zachaeina Bilr. (144 k) differs from isola by its deeper purple-blue above and like in cyna a plain :<irliacina. 

 brown macular band on the lighter under surface of the forewing, the spots being smaller and narrower; only 

 2 costal-marginal spots and one basal spot of the hindwing are jet-black. Florida, Antilles, Cuba, Jamaica, 

 Dominica, Central America, Colombia as far as South Brazil. 



H. hanno Stoll. (= antibubastus Hhn., hamo Luc, pseudoptilete Bsd. d- Lee, astenidia Bsd.. filemis hamw. 

 Poey.) (144 k) forms about the middle between isola and zachaeiiia, above not different from i.sola. the blue 

 colour perhaps somewhat duller. The under surface is brown-grey, marked like isola, but the postdiscal row 

 of spots is not jet-black, but brown like in zachaeina, the spots smaller, the uppermost placed far inwards. On 

 the hindwing the whitish marginal band is absent, and there is only one small black anal spot with a silvery 

 green j^upil and encircled by a faintly rusty-yellow ring; beside this .spot there are in the basal area 3 and at 

 the costal margin 1 prominent, jet-black, small eye-spots. Mexico to Colombia (Bogota). Specimens from the 

 latter habitat are beneath much darker and more monotonously brown: bogotana /. vov. hiujoiatw. 



H. ramon Dogn. resembles above small specimens of hanno. The colour beneath is lighter ashy-grey, ramon. 

 towards the margin strewn with blue atoms, the marking like \\\ hanno; on the hindwing only in the basal 

 area the 4 jet-black, small eye-spots are prominent, all the others are brown-grey: at the border there are here 

 4 black small spots pupilled metallic green. Described from Ecuador (Loja). Expanse of wings: 22 to 25 mm. 



H. martha Dogn. is still smaller, above with a somewhat broader black border and a series of black murfha. 

 marginal dots on the hindwing. Beneath like ravioli: but on the hindwing in the middle with a large white 

 transverse spot bordered with brown beneath; the 4 marginal eye-spots are in a brown ground. Expanse 

 of the wings: 19 to 22 mm. Ecuador (Loja).
