754 THECLA. By Dr. M. Draudt. 



diqnoUi. Th. dignota sp. nov. (153 b) differs from aegides (148 h) by a rather large, round, greyish-brown 



scent-spot at the cell-end, a very sharp apex of the forewing, below which the distal margin looks almost concave, 

 red-brown fringes and tail; the anal lobe is likewise quite red-brown, in its centre pupilled with some greenish- 

 silvery scales, the fringes at it partly white; the bluish-white line in front of the border is absent altogether. 

 Beneath, on the cinnamon-brown ground-colour, are the same transverse lines, but they are fine black, strewn 

 with silvery-grey scales and only towards the costa of the forewings somewhat broader and whiter; the third, 

 counting from the base, is regular and sharjsly dentate with distally concave bows. Described according to 

 a ^ from Bogota (Coll. Fassl). 



comae. Th. comae Drc. (149 a) forms the transition to the following species by the ^J forewing exhibiting 



a large discal spot of modified scales of an oval shape, which, however, stands out against the colour of the 

 wings only in an oblique exposure to light; besides this the species resembles above aegides (148 h); the under 

 surface is niore blackish-brownish, the line-marking otherwise very similar, but on the forewings, subapically, 

 are the beginnings of a 4th line and on the hindwings, between the median veins and in front of the black- 

 pupilled anal lobe, are 2 black spots in light, reddish surroundings. C^olombia (Muzo; Rio Aguaca Valley). 



■ion. Th. ion Drc. (149 a) has the same, hardly noticeable scent-spot, is somewhat lighter, more 



greenish-blue and has much narrower, black distal margins. Beneath like the preceding, but the o lias an opales- 

 cent blue discal spot of the fore^^'ing. Colombia. — From Medina (East Colombia) there is a (^ before me (from 

 c.rfroiia. the Coll. Fas.sl) which I should like to include here provisionally as a subform: extrema form. nov. (153 b). 

 It is above still lighter, greenish silvery-blue, entirely without a black distal margin, the discal spot is above 

 still larger and beneath the whole forewing is opalescent blue, so that there remain of the transverse lines only 

 3 minute white spots at the costal margin. 



harha. Th. barba Drc. (149 a) has narrower wings than the other representatives of the group, above very 



broad black margins and beneath on the forewings only one bluish-white transverse line crossing the disc; on 

 the hindwings the basal transverse line is only indicated by a co.stal marginal .streak, the marginal line is absent 

 altogether. Colombia (Muzo; Rio Aguaca Valley). 



aiidti. Th. auda Heiv. (149 b, c) is a somewhat smaller species, above more violettish-blue with broad black 



margins; beneath greyish-brown with quite a similar linear marking as the preceding species, but in front of 

 the border of the hindwing are 2 undulate, parallel, light lines, between them, at the anal angle, 3 black, triang- 

 ular spots being above bordered by orange-red. Occurring in Colombia and common, but it also lies before 

 me from Lino (Panama) from the Coll. Fassl. 



cMamydem. Th. chlamydetTi Drc. (149 c, d) is perhaps only a form of auda; above more indigo-blue with broader 



black margins; beneath, on both wings, the distal white transverse lines are more distinct, and on the hindwings 

 the discal markings are doubled by proximally white dusting. Peru, at an altitude of 5 to 6000 ft. 



sala. Th. sala Hew. (159 a). We herewith include some species exhibiting at the same time close relations 



with the coe/ico/or-group following later on. Sala is above dull violettish-blue, on the forewings with broad 

 blackish-brown margins, on the hindwings very narrowly margined with the fringes parted by white towards 

 the anal angle. Beneath dark brown, in the (5*-disc of the forewing with a slight steel-blue shine. The marking 

 is similar to that of auda (149 b, c), but on both wings the basal transverse lines are absent, and the post-discal 

 of the hindwing runs almost straight from the costal margin to the lower median vein. Colombia. 



marachefs. Th. tTiaraches Drc. (159 a) is very similar, aliove more lustrous steel-blue, the shape of the wings as 



in epopea (157 c) and the tails as fine as they are there. Beneath not so red-brown, more blackish-brown, the 

 lines clear and distinctly light-blue, much straighter, on the forewings at the costal margin more moved apart, 

 continued to the proximal margin, the submarginal on the lowest subcostal vein distally obtuse-angled. On 

 the hindwings the postdiscal begins also much further towards the base, at the anal angle there are only 2 deep 

 brown-red spots. Colombia (Canon del Tolima, Fa.ssl). 



salaeides. Th. salacldcs Sp. nov. (159 a) is very closely allied to sala, but it is above of a lustrous ultramarine- 



blue, the margins and apex only half as broad and jet-black, the shape like snla. but the tails very fine. Beneath 

 almost just the same as sala, but on the forewings the postdiscal makes a deep bend towards the base, 

 below the lower median vein; on the hindwings it begins at the costal margin more towards the base, and there 

 is a second, dusty-white lunular line in front of the border; 3 red anal lunae. Colombia: Pacho (Fassl). 



peomda. Th. peotiida .ip. nov. (159 a) likewise greatly approximates the preceding species, above brilliantly 



metallic sky-blue, with a broad black apex and distal margin of the forewing, a similar costal margin of the 

 hindwing, and a narrow di.stal margin; in the anal lobe a short white line; the base of the fringes in that lobe 

 also white. Beneath very much like salaeides, distinguished by a short metallic-blue stripe in the disc of the
