aidolycus. Til. autolycus £du'. (154k) resembles melimts (159g) above, but the orange spots are much more 



extensive. Beneath brown, simihxr to the preceding species, with dark, distally white-bordered postdiscals 

 and black submarginal crescents which are analwards distally spotted in red. Texas, Missouri and Cansas. 



alcestis. Th. alcestis Edw. (154 k) is above dull-brown with the usual oval scent-spot in the (J, beneath very 



much like autolycus with whitish discal streaks and dusted greenish-blue in the submarginal submedian area 

 of the hindwing. Texas and Arizona. 

 nskiri. Th. oslarl Di/ar is closely allied to alcestis, but smaller, the upper su)'face greyer brown, beneath 



ashy-grey instead of brown, and the red markings outside the distal band are less developed. Expanse of wings 

 16 mm. Tucson, Arizona. 



acadica. Th. acadica Edw. (= = souhegan Whitney) {154 k). The upper surface is brownish slate-grey, towards 



the anal angle \\ith small orange spots on the hindwings and an oval scent-spot. Beneath differing by black 

 cell-end-streaks and by the postmedian and submarginal macular rows being replaced by smaller black, white- 

 ringed spots; analwards there are small antemarginal red spots, and between the spot of the tail and the anal 

 spot there is greenish-blue dusting. — The larva lives on willows. Northern States, Nevada, Arizona. 



califortiica. Th. califomica Ediv. (= borus Bsd., cygnus Edw.) (154 k) differs from acadica above by its light- 



brown colour, also on the forewings at the proximal angle with 2 small orange spots; beneath grey, with a 

 reddish-brown tinge, near the apex of the forewing with small reddish-yellow marginal lunulae. In the $ the 

 under surface is more dirty white. California. 



itys. Th. itys Edw. (154 k) is above brown, particularly in the V with a light reddish-yellow brightening 



towards the proximal angle. Beneath light greyish-brown, the submarginal row of spots quite obsolete on the 

 forewings, on the hindwings there is here a complete row of black dots; at the anal angle a velvety-black spot, 

 above it some small orange scales; between this and the orange spot of the tail a bluish spot margined in black; 

 the postdiscals consist of minute black, white-ringed spots. Exjjanse of wings: 32 mm. Prescott, Arizona. 



avrctorinii. Th. auretorum B.sd. Above brown with 1 or 2 small orange spots towards the anal angle on the hindwing, 



beneath likewise brown, the row of eye-spots undulate, not very distinct and placed near the border, at the 

 anal angle with 2 tiny reddish-yellow lunulae, the anal lobe bordered by black. California. 



dryopc. Th. dryope Edw. (154 k) is above quite light-brown, towards the base slate-grey, at the anal angle 



with 2 small yellowish-red spots, the one below the median veins behig pupilled in black. The under surface 

 is whitish-grey with the usual rows of eye-spots and a small orange spot between the tails. California, Nevada, 

 Utah. 



sylvinus. Th. sylvinus Bsd. is above darker blackish-brown, otherwise very similar to the preceding. Beneath 



light ashy-grey with a dark cell-streak and 2 curved rows of eye-spots, the hindwings between the tails with 

 small orange, black-pupilled spots and towards the proximal margin from them a bluish-grey spot. Common 

 in California. 



pidnami. Th. putnattii Edw. 30 mm. Above fawn-coloured with white fringes. Hindwings with 4 indistinct, 



dark small crescents and an anal spot covered with golden-yellow. Tails black, with white margins and a broad 

 white apex. Under surface greyish-white. Forewing with a discal luna and 6 submedian, oval spots, each with 

 a white ring; near the anal angle 4 black streaks. Hindwing with a discal hina and a row of 7 spots. Marginal 

 markings obsolete, anal spot orange, marked in black, the 2nd and 3rd with interspersed small blue scales, 

 the 4th black, above orange. Utah, Colorado. 



spadix. Th. spadix Edw. is allied to the preceding and just as large. Above mouse-coloured with a large, 



chestnut-browii shade on the forewing. The band-marking beneath very much blurred, on the hindwing irre- 

 gularly broken; the anal spots are dirty brown, there is not the least to be noticed of orange or blue. Exjjanse 

 of wings 24,5 mm. South Carolina. ' 



tetra. Th. tetra Behr. Above light-brown, beneath lighter; both wings with a joint, more indistinctly tortous 



median row of whitish lunulae; on the hindwings small black, antemarginal crescents, anteriorly with some 

 whitish scales. Tail-spot orange, between it and the anal angle a blue spot. Expanse of wings: 30 mm. ('ali- 

 fornia. 



56. Behrii-Group (CnUipsyche Scudd.). 



hehrii. Th. behrii Edw. (= kali Streck.) (154 k) somewhat resembles the subgenus Erora in the scheme 



of markings beneath. Above red-yellowish brown with a broad blackish-brown costal and distal margin. 

 Beneath yellowish-grey with a curved, on the hindwings strongly broken, postdiscal band of black, distally 

 white, small spots and small submarginal lunular spots, between the median veins of the hindwings with a
