ITYLOS. By Dr. M. Draudt. 821 



L. ochsenheimeri Godt. Whether this species unknown to me is to be placed here, I cannot decide; it ochsenhei- 

 at any rate seems to me to be allied to callanga. Above blue-violet with a brown margin and white-speckled ^^'^• 

 fringes. Beneath the disc of the forewing is red-yellow with some small light yellow ring-spots, a white undulate 

 line before the apex and black marginal dots. The hindwings are beneath of a dirty brownish; in the basal area 

 there are grey rings, behind the middle an undulate snow-white band and 5 small black marginal spots, at the 

 anal angle 3 small spots strewn with a golden green. Expanse a little more than an inch. Described from the 

 Antilles, though doubtful. 



15. Genus: Itylos gen. nov. 



Anatomically hardly separable from Lycaena, but the total impression of these small insects flying 

 only in Tropical America, mostly at great altitudes, is so characteristic that the separation is justified. The 

 hairmg of the body is stronger, particularly the palpi show a much longer, somewhat porrect, beard-like hairing 

 on the underside, whereas laterally they are covered with broad scales. Costal and subcostal vein of the forewing 

 run separately. The fringes are uncommonly long, mostly speckled very conspicuously; the colour above is a 

 metallic blue of a very intense mother-of-pearl gloss, in other species silvery or coppery bronze are predo- 

 minant ; the under surface of the hindwings mostly shows conspicuous silver j^-white macular marking or pecu- 

 liarly brown serpentine lines. As to the synonymy this group offers great difficulties, because there are a 

 lot of obvious manuscript names, but no descriptions. 



I. pelorias Weym. (144 m) I only know from the description and figure, it must be extremely allied to pelorias. 

 the following; the brown upper surface exhibits a silvery grey-blue lustre only in the basal area, the fringes 

 are sharply speckled brown and white. Beneath like pads, but the brown transverse markings of the hindwings, 

 having moreover the same course, seem to be darker black-brown and more distinct; in the marginal area there 

 are no markings whatever. Described according to a (J from Bolivia (Sajama) between 3600 and 4600 m. Length 

 of forewings: 10 mm. The specimen denoted as (J, however, may anyhow bet he $ of the following form, which 

 would then become S3aionymous. 



I. pacis Stgr. i. J. (144 1, m) is above extensively violet-blue with a purple lustre, towards the margin 2^acis. 

 brown with distinctly white-speckled fringes, in the $ only in the basal half silvery blue-violet, at the border 

 much broader reddish-brown. Beneath reddish-brown, on the forewing with a discal spot and a series of post- 

 discal spots, in the marginal area indistinct, double, darker, small lunular spots in a ground dusted whitish; 

 the hindwings, on a ground being more intensely dusted whitish, show irregularly torn, dark brown spots in 

 the basal area and a more distinct transverse band from the costal angle to the middle of the proximal angle, 

 projecting far towards the margin between the lower radial veins, and below it with a large silvery white spot ; 

 another white patch is situate at the costal margin between a basal spot and the beginning of the transverse 

 band. Marginal markings indicated like on the forewings, between the median veins more distinct. Peru (Cuzco). 



I. koa Drc. (144 m) is above duller and darker, beneath somewhat lighter; on the forewmgs the kod. 

 spots are not darker than the ground, their white edges appear as white, coherent undulate lines; on the hrndwrng 

 there is a complete white longitudinal ray in the costal-marginal area, traversing the dark transverse band, the 

 white spot in the anal area is also larger and bifurcates towards the distal margin. Peru, Bolivia, apparently rare. 



I. vapa Stgr. (144 m) approximates the preceding; it is above monotonously brown with broadly vapa. 

 white-speckled fringes. The under surface is very much like that of foa, but much lighter; the sUrery white 

 costal-marginal stripe extends to the costal margiir itself and in it there are about in the middle 3 small round 

 spots of the pale brownish ground-colour; the white spot below the discocellular is much more extensive and 

 almost reaches to the base. In Peru and the Bolivian Andes between 3 and 4000 m (Cuzco, La Paz, Huallatani, 

 Cocapata). 



L ludicra Weym. (144 m). This species described according to but onQ specimen must likewise be hidicra. 

 closely allied to kod and vapa, the upper surface, however, is described to be light silvery blue as m our Lye. 

 eros, though with a much stronger lu.stre; the narrow brown distal margin gradually warms into the blue colour 

 and is somewhat broader at the apex; at the cell-end there is a brown streak; the fringes are speckled bro'rni 

 and white. The under surface is light yellowish-brown, the macular bands recognizable onlj^ by their white 

 bordering. The fringes are all white in the basal half, and speckled only in the distal half. On the hrndwrng 

 the silvery-white costal-marginal stripe is distally broader, sending forth an off-branch on the subcostal vein. 

 As the remainder of the brown transverse band of the preceding species there are a series of dark-bro\^m crescenti- 

 form streaks bordered distally by white, from below the lower radial vem in the shape of a broad white band; 

 at the proximal angle several small white spots, the one between the median vems with a black pupil. Length 

 of forewings: 10 mm. Bolivia (Tacora), 3600 to 4600 m. 



I. moza Stgr. is a somewhat larger species, above lustrous smoky-brown with an intense metallic moza. 

 lustre, distinguished by the unspeckled fringes being in the distal half dirty white, in the proximal half darker
