THECLA. By Dr. M. Draudt. 771 



half lilac-white with a submarginal brown macular band and an orange spot between the median veins. In 

 the purple-brown basal half there is a white macular band before the centre and behind it a second one being 

 broadly dusted in grey on both sides. Amazon. 



Th. olbia Hew. (154 f) has a larger, double, proximally black, distally brown scent-spot and the olhia. 

 ground-colour is a purer sky-blue with a very broad blackish-brown apex. Beneath the forewings are reddish- 

 brown-grey, towards the distal margin densely dusted in white with the same lines as the preceding, and a white 

 discal streak ; the hind wings are silvery white, densely clouded in brown, with an indistinct brown, di.stally 

 white-bordered, undulate median band. Amazon. — In the form phallica Heiv. (154 f) the white du.sting be- phallim. 

 neath is almost entirely absent. 



Th. erema Heui. (= biston Mschlr.) (154 f) exhibits above a somewhat more violet tinge in the erema. 

 still more reduced blue and has a very complicated, uncommonly large scent-spot filling up almost the whole 

 cell: red-bro\^Ti, proximally bordered by slate-blue, distally with 2 irregular, darker brown triangles on it, the 

 surroundings of which are, distally and towards the costal margin, again dusted in red-brown. Beneath browTi 

 with fine, white, torn markings and black spots at the anal angle and between the median veins. Guatemala, 

 Guiana, Amazon. 



Th. elsa Hew. (= primno Godni. & Salv.) (154 g) reminds us of the preceding, but it seems hitherto elsa. 

 knowTi only in the $. Above greenish-blue, with broad blackish-brown margins; beneath purple-browii, the 

 proximal margin of the forewings whitish, otherwise marked as in avoca (154 f). Hindwings with irregular, 

 fine, white markings and a white spot in the middle of the costal margin, distally broad whitish, dusted dark, 

 between the median veins with a straw-coloured spot. Described from Panama. 



Th. feretria Hew. (154 g) I do not know in nature, but it seems likewise to be allied to erema and lereMa. 

 to be described only according to 1 $. Above like elsa, beneath reddish-brown with a small white basal spot 

 on each wing; forewing at the costal margin dusted in purple-brown with a white discal streak, a white post- 

 discal macular band and light antemarginal band; hindwings at the base and in the centre purple-broTwi, ^\'itli 

 a very irregular white macular band in the middle and a light-brown antemarginal band; the anal lobe and a 

 spot of the tail are black, the distal margin between is white. Habitat unknown. 



Th. primnoza Dyar is perhaps the ^ of elsa, above blackish-brown, in the basal two thirds of the prbnnoza. 

 proximal margin as far as the lower cell- wall and in the disc of the hindwing light metallic blue, consequently 

 about as in e?'ema (154 f ), with a most peculiar dark-grey scent-spot extending subcostally almost in half the length 

 of the wings. Beneath dark grey, at the proximal margin whitish, hindwings only in the basal third grey, distally 

 whitish, marked about as elsa, bi.it the spot of the tail is abo~ve bordered by red. Expanse of wings: 30 mm. 

 Mexico. 



Th. hirsuta Prittiv. is likewise unknown to me; it is described as a $, but according to the very hirsuia. 

 peculiar scent-spot which seems to be equal to that of primnoza, it can only be a (J; below it, at the cell-end 

 there is yet a coniform black spot. Forewings blackish-brown, dusted in blue, two thirds of the hindwings 

 blue with a dark costal margin; fringes white and grey speckled. Beneath light-grey, the forewings marked 

 as in elsa; hindwings behind the postdiscal dusted in a sooty brown, the darkest at the costal margin; in this 

 area there is yet a line formed of white crescents; at the anal lobe and between the median veins there is one 

 orange spot each with a black pupil. Size and shape of Th. quercus. Brazil. 



Th. megamede Prittw. may also belong into this group. Above azure, with brownish black margins, megamcde. 

 the discal spot light grey. Forewings beneath grej', at the border whitish, the broadest at the apex, m it an 

 obsolete, grey macular band, farther proximally follows a brown, somewhat curved band, still farther some 

 small white spots at the costal margin. Hindwings chestnut-brown mixed with white, at the costal margin a 

 conspicuous white trapezoid-spot dusted in the middle by yellowish ; in the centre the traces of a -white, dentate 

 line, the basal area quite chestnut-brown; at the anal angle a black spot being bordered above by white. Patria ? 

 This species may belong near olhia (154 f). Size and shape of Th. ilicis. 



Th. zenaida Dyar, likewise unknown to me, is the best ranged here. The (J is above black, dusted -enaida. 

 all over in blue except the margins, with an elliptic brown scent-spot filling up the distal half of the cell. The 

 $ is dusted in a duller blue. Under surface dark brownish-grey, on the forewings a fine white, antemarginal 

 moon-spot-line, proximally shaded by a broad dark-grey. Hindwing with a dark-grey shade at the base and 

 in front of the margin; the centre is crossed by a white moon-spot-line being marked very irregularly at the 

 cell-end; behind it another irregular moon-spot-line; marginal area whitish with a dark undulate line before 

 it; between the median veins a black spot being red above. Expanse of wings: 29 — 31 mm. Mexico. 



51. Lycabas- Group. 



Th. lycabas Cr. (= terentia Heio.) (154 g). We unhesitatingly set down Cramer's figure which lycahas. 

 has hitherto not been noted to Hewitson's species. The (J is above dark brown, suffused by a deep violet-blue
