760 THECLA. By Dr. M. Drattdt. 



angle of the hindwing. Above brown; beneath dull brown, on the forewing before the apex at the costal margin 

 a light small spot bordered on both sides by brown. Hindwings whitish, clouded in brown; a small spot at 

 the base of the costal margin, a broader band in the centre and an irregular marginal band dark-brown. Colombia. 

 crambiisct. Th. crambusa Hew. (154 f) is somewhat larger, of the same shape of the wings, but with a shoi't 



small tail on the lower median vem. Brown with small black spots in the anal part of the hindwing. Fringes 

 white, on the fore->^ing partly b^o^vnish. Beneath very much like the preceding, somewhat more multifariously 

 marbled with a chestnut-browTi spot bordered on both sides by whitish in the middle of the proximal margin 

 of the hindwing, between the median veins a rusty-yellow spot and near the anal angle greyish-white dusting. 

 Brazil, Bolivia. 

 hinangiila. Th. binangula Schs. is lmkno\^^l to me like the following, but presumably belongs here; the shape of 



the wings is the same as in crambiisa. Above dark-brown with a darker spot at the cell-end and some blue at 

 .the base of the forewing; hindwing, except the broad brown costal margin, light-blue with a small black spot 

 between the median veins. Beneath greyish-brown with a dark cell- end spot bordered on both sides by white; 

 the witish apes is marbled in broA^Tiish-grey and proximally bordered by a brown, distally white shade. Hind- 

 wing with a romid brown, white-ringed spot at the base of the costal margin; postdiscal double, whitish, inwardly 

 bordered at the costal margin and j)roximal margin by a white angular spot; distal margin darker, dusted in 

 reddish towards the anal region. Expanse of wings: 19 mm. Peru. 

 bolima. Th. boHtna Schs. is much larger, the forewmgs more roiuided. Above similarly coloured, but with 



black spots in front of the distal margin of the hindwings. Also beneath very similar with distinct brown, white- 

 ringed spots in the centre of the costal-, cell- and proximal margin. Castro (Parana). 



32. Culminicola- Group. 



culmimcola. Th. cultnitiicola Stgr. (153 g). Above deep violet with black margins and a particularly broad apex. 



Fringes white-speckled. Statjdisger, in his description, has overlooked the greyish-brown scent-spot at the 

 upper cell-end. Beneath blackish-grey, particularly distally strewn with white, with black dentate lines. The 

 $ is above extensively light bluish-grey with a lUae shine. Colombian Andes at an altitude of 3500 to 4400 m, 

 also from Cuzco (Peru). 

 alatus. Th. alatus Drc. (153 g, h) may be a distinct species owing to the unspeckled reddish fringes. The 



upper surface is lighter violettish-blue with a red lustre, the scent-spot is the same. The disc of the forewing 

 beneath orange. Described from North Peru (11 500 ft.). 

 cmosma. Th. anosma sp. nov. (153 h) is above quite dark-brown without a scent-spot, only the hindwings 



exhibit a faint violet lustre in the disc on bemg obliquely exposed to the light. Fringes mispeckled, brown, 

 hindwing with a longer small tail at the lower median vein. The monotonously greyish-brown under surface 

 stre^Ti with red scales, with incoherent dark lunular spots entirely resembles that of bilix. A ^ from Bogota 

 (3000 m) from the Coll. Fassl. 



33. Irus- Group {Incisalia Minot). 



augustus. Th. augustus Ky. (= augustinus Wio.) (153 h) undoubtedly is closely allied to the preceding gxoup. 



Above brown, the hindwings analwards copper-reddish. The under surface is reddish-brown, in the basal half 

 darker with a dark dentate median band of the hindwing and lighter, proximally darker-bordered, small triangu- 

 lar spots in front of the more purple-brown border. Distributed m the northern and western parts of North 

 America. Larva carmine-red, with short hair. 

 iroidcs. Th. iroides Bsd. is extremely allied to augustus, above not different, beneath the space behind the 



postdiscals is not lighter than the border, the markings are more indistinct, the forewmgs almost unmarked. 

 inijuaculaia. Vaciiic States. — f. immaculata Cokle is an albiao form: straw-coloured to canary-yellow, above and beneath 

 without any spots. A unique specimen from Kaslo in British Colombia. 

 foiis. Th. fotis Strecker. Size and shape of augushis (153 h); above unieolorously dark-g•reJ^ Beneath the 



forewings are rather dark slate-grej^; with a submarginal row of almost obsolete dark dots, a hardly distinguish- 

 able, irregular, darker line through the disc ; inwardlj' from the latter the wing is strewn with lighter atoms. 

 In contrast with augustus, the hindwmg exhibits beneath near the distal margin a white Ime followed by a 

 band which is composed of dispersed, black, small scales, proximally from it a series of round, white spots or 

 dots, each of which exhibits some black atoms ; proximally from it a not very distinct light, dark-tinged line. 

 From Arizona. 

 hadros. Th. hadros Cook d- Watson. (^ above brown, $ bright rusty-red with a copper-lustre, towards the 



margm and the base somewhat clouded. Frmges one-colom'ed, only near the apex with a white margin. Beneath 

 dark-bro-«ii, the hindwmgs towards the margins dusted m grey, the broadest at the anal angle, otherwise marked 

 like irus, mostly only faintly indicated ; on the hindwings in the centre of the costal margm with a white diffuse 

 spot; on the forewings stands a whitish postdiscal. Expanse of wings: 32 to 38 mm. — Texas.
