THECLA. By Dr. M. Dratjdt. 763 



Th. acaste Prittiv. (= lycimna Hew.) (154 a) entirely resembles herodotus (153 i) except the absence acaste 

 of the tail, but on the hindwing beneath, it exhibits a complete and scarcely interrupted, fine, white transverse 

 line, being proximally mostly tinged with cherry-red; there is often also a white discal streak. Brazil (Sao 

 Paulo, Rio Grande do Sul, Sta. Catharina). 



Th. remus Hew. (154b) is above more greenish-blue; beneath the transverse band of the hindwing remus. 

 consists of small red-brown spots, of which only the lowest is white-pupilled ; close before the border there is 

 yet a row of small black, white-dusted spots. The $ is above greyish-blue, beneath more richly marked in red- 

 brown, as far as to the costal-marginal angle of the hindwing; also on the forewing there are behind the middle 

 of the costal margin small red- brown spots. Brazil. 



37. Dumetorum- Group {Callophrys Billh.). 



Th. dumetorum Bsd. (= viridis Edw.) (154 b) replaces our Th. (Callophrys) rubi in North America, dumetorum. 

 Above blackish-brown, in the (J with a smooth oval spot at the cell-end, fringes whitish, at the anal angle brown. 

 Beneath deep green except the proximal margin of the forewings being brownish-grey; the proximal margin 

 of the forewing red-yellow; both wings are traversed by a curved band of oblong, white small spots. — The 

 egg is deposited on the flower-buds of Hosackia argophylla, but the larva is not yet known. California, Rocky 

 Mountains. 



Th. affinis Ediv. does not differ above, but beneath it is quite unmarked green. Utah. affinis. 



Th. apama Ediv. from Arizona is above like dumetorum (154 b), beneath marked almost like castalis; apama. 

 untailed. Above blackish-brown with an oval, black stigma; beneath the forewings are yellowish-brown, in 

 the apical area and at the costal margin golden-greenish ; in the disc a transverse row of small spots consisting 

 of black, distally white-tinged, proximally red-brownish-tinged, small streaks. On the hindwings there is a 

 discal, somewhat irregular row of similar spots of which those in the costal half are moon-shaped; expanse 

 of wings: 27 mm. 



Th. sheridanii Ediv. is the last species belonging to the ,,Callophrys"-group. It has hitherto been sheridanii. 

 exclusively found in the Rocky Mountains. 



38. Janias-Group. 



Th. janias Cr. (= romulus F., cecina Heiv.) (154 b) is above magnificently deep ultramarine-blue janias. 

 with black veins, a broad black apex and a narrower black distal margin. In the upper cell-corner in the apical 

 black a dark brownish-grey scent-spot. Beneath magnificently emerald-green including the thorax, legs, forehead, 

 palpi, borders of the eyes and shoulders. On the hindwing there is a postdiscal transverse line mostly present 

 only analwards and forming here a W, a spot between the median veins, the tail and the white-bordered fringes 

 velvety-black. In the $ being above greyish-blue to brown, on the hindwing beneath, the black transverse line 

 is complete as far as the costal margin, also a large black anal spot. — In the form hassan Stoll (154 b) the hassan. 

 black spots above are bordered by a broad orange-red. Most widely distributed from Mexico through the whole 

 of Central America as far as Guiana, Colombia, Bolivia, the Amazon, and South East Brazil. 



Th. esmeralda Jones (154 b) is closely allied to the preceding, but it has above much broader black csmeralda. 

 margins; beneath the hindwing exhibits a fine, black, undulate postdiscal line, being the most distinct at the 

 proximal margin. The spot between the median veins is quite orange. The $ is above brown with a faint lUac- 

 grey lustre; beneath the black undulate line is more distinct, the orange spot larger, a second one is at the anal 

 angle. Castro (Parana). 



39. Thabena-Group (= Jaspis Kaye). 



Th. thabena Hew. (154 b). Above brilliant blue with a large black scent-spot in the cell of the fore- thabena. 

 wing, a narrow black margin and a somewhat broader apex; beneath light-grey with 2 fine transverse lines, the 

 proximal one inside bordered by orange, outside by white and beginning at the margin of the hindwing with 

 a distally arranged, large black spot, strongly dentate; anal angle extensively yellow. The $ is above dark 

 brown, at the anal angle of the hindwing and at the proximal margin white-spotted. Surinam to the Amazon. 



Th. temesa Hew. (154 c) is beneath almost like thabena, but above very dark ultramarme-blue tcmesa. 

 with a brown oval discal spot. Guiana to the Amazon. 



Th. talayra Hew. (154 c) is above brilliant-blue, bordered like thabena, but with a small scent-scale- talayra. 

 spot of the same colour at the upper cell-end. The under surface is lighter, almost white, the line-markings the 

 same, but at the anal angle two orange-red spots. Common from Mexico to Brazil. • — From Para and Espii-itu 

 Santo the f. castitas Drc. (154 c) is described with a much duller, more greenish blue and a somewhat broader caMiias. 

 black margin; the under surface is darker, at the anal angle more red.
