772 THECLA. By Dr. M. Dkaudt. 



with a brownish-grey oval scent-spot, the $ is duller and more greenish blue with a marginal line being distally 

 bordered by white, proximally by black, near the anal angle of the hindwing, which is long-stretched almost 

 like a tail. The under surface has very characteristic markings similar to those of the Maea-group. Panama, 

 Colombia, Amazon. 



52. Xami- Group. 



xami. Th. xami Beak. (= blenina Heu\, siva Ediv.) (154 g) is above brown, in the disc often more or less 



red-yellow; beneath pea-green on a red-brown ground with curved red-brown, distally broad white postdiscals, 

 behind them distinct submarginal spots and orange anal spots. Vancouver, Arizona, California, Mexico. 



rhodope. Th. rhodope Godm. & Salv. (154 g) is similar to xami, but the hindwings exhibit above a large 



orange anal spot and small black submarginal spots. Beneath, the postdiscal band is more strongly undulate, 

 at the median veins broken, but not deeply angled. Mexico. 



loki. Th. loki Skinner is above light brown with a tiny black lunular spot at the anal angle of the hindwing, 



being jjroximally somewhat lighter. Beneath light bro\ATi with a greenish tinge, marked as xami, but easily 

 separable by a series of black submarginal spots, extending from the costal margin to the anal angle. California. 



spinetorum. Th. spinetorum Bsd. (= ninus Edw.) (154 g,h). Above grejdsh-brown, towards the base tinged 



in a greenish bluish-grey; beneath dull reddish-brown, marked like xami. Colorado, California, Mexico. 



johnsoni. Th. johnsotii Skinner is regarded as a doubtful form of the preceding by the author. Above reddish 



brown without the bluish-grey tinge, with a darker costal margin. Beneath the same, but the white postdiscals 

 not so coherent, more like small spots, particularly on the hindwings, on which the 5th (beginning from the 

 costal margin) is displaced, the last being longer than the others. Marginal line black, on both sides with white 

 borders, at the anal angle terminating into a black spot; there are no orange anal spots. The smaller and darker 

 cj exhibits the usual sexual spot. Length of forewings 14 to 15,3 mm. British Colombia; Seattle, Washington. 



castalis. Th. castalis Edw. ^ above yellowish-brown, both wings with a broad dark costal and distal margin. 



Stigma small, oval. Hindwing somewhat darkened in the disc; the distal tail quite short, the other long with 

 a white apex; forewings below at the base and in the apical part of the margin green, the rest chestnut-brown, 

 the shortened, interrupted discal band white. Hindwings beneath green with a white marginal line exhibiting 

 3 small, bluish-grey crescents at the anal angle, at the middle one of which there is on top a black spot. Right 

 across the disc runs a sinuous chain of small white spots being anteriorly margined in brown. $ above chestnut- 

 brown, the green beneath darkened. Expanse of wings 21 to 30 mm. Waco (Texas). 



ilavia. Th. ilavia Beutenm. from Texas has a resemblance to autolycus (154 k), but it deviates by the under 



surface of both wings exhibiting only 1 tran.sverse line. ^ above brown Avith a large, red-yellow postdiscal spot 

 of the forewing and a similar, though smaller spot in the anal part of the hindwmg. Beneath rather light loam- 

 coloured; on the forewing an interrupted, distally white-tinged transverse line. The dark line of the hindwing 

 forms a W at the anal angle. At the anal angle itself a blue-scaled lunula, in front and behind this a small, 

 black-marked, orange spot. $ similar. Expanse of wings 24 to 26 mm. 



nclsomi. Th. nelsonii Bsd. (154 h) is above blackish-brown, in the disc bright red-yellow as xami, beneath 



duller reddish-brown, marked very much like the preceding species, but much more indistinct, the lines much 

 exoleta. finer, the small antemarginal sjDots smaller. • — The form exoleta Edw. has beneath entirely obsolete transverse 

 muirii. lines, f . muirii Edw. is smaller, with a darkened basal part of the hindwing beneath. California, Colorado. 



adenostoma- TH. adenostomatis Edio. (154 h) is the largest species in this group, above greyer with a fine, white 



'*■ marginal line at the anal angle of the hindwing; the under surface is whitish brownish-grey; the somewhat 

 lighter marginal area is defined on the forewing by a Avhitish line, on the hindwing by dark submarginal moons. 

 California. 



iacita. Th. tacita Edw. Allied to the preceding, above light leaden-coloured, at the margin somewhat darker, 



as well as the discal spot and the veins. The tails of the hindwings very small and thin; near the anal angle 

 of the hindwing an obsolete oclireous shade; fringes of both wings dull white. Under surface lighter; before 

 the border a line of dark, small crescents; across the centre a curved chain of small oval spots. Hindwings 

 marked indistincth^, at the anal angle a small black spot, as well as a bluish spot and hereafter a triangular, 

 light yellowish, black-margined spot. Expanse of wings 24,5 mm. California (Mendocino Co.). 



saeplum. TH. saepium Bsd. (154 h). Above yellow red-brown, beneath dull reddish-brown, with the usual 



lines being distally distinctly tmged in white; at the anal angle of the hindwing 2 small black spots, between 

 fttlvesccns. which there is bluish-grey dusting. Pacific States. — In Colorado there occurs fulvescens Edw. being still lighter 

 vello wish-red.
