THECLA. By Dr. M. Draudt. 787 



})r(i\vnisli-grey, sometiim's very large, sometimes very small. Just as common as ediion. From Mexico to 

 tjoutli Brazil. — The northernmost specimens from Mexico, greppa Dynr, have an almost white under surface, nrrjipa. 



Th. giapor Sch.s. (!(»() d). Above blue as crolinu-s. but with the (hiuble scent-spot of the ]ii(!cteding, (jucpor. 

 the distal, grey portion smaller. The under surface likewise as in crolinus, but with a fine streak at the cell-end, 

 the spots on the hindwings more coherent, linear, the postdiscal straight from the costal margin to the lower 

 radial vein. Sao Paulo. 



Th. fostera Schs. is uid^nown to me, but it ])resumal)ly belongs here. Only the 5 is known : above jiisicni. 

 brown, the forewings only at the proximal margin, tlie hindwings more exten.sively dull light-blue; at the 

 distal margin of the latter there are in the anal part 3 small red spots, above them some black ones. Beneath 

 light -grey with a fine, red marginal line and a red streak at the cell-end; on the forewings a row of red spots 

 from the costal margin to the lower median vein, the second spot from below inwardly displaced; on the hind- 

 wings a red cell-spot and one above it, jiostdiscally a row of large, red spots, forming a broken W at the jsroximal 

 margin; at the border the 2 usual red spots; above the upper median vein yet a third, smaller one. On the 

 head a red spot. Sao Paulo. 



Th. cydrara Heii\ (156g) and its nearest allies we most appropriately combine with the ec/(»o«-grouj) (iidmra. 

 to which they exhibit many relations. Above almost like echiov, only somewhat more metallic greenish-blue. 

 Beneath very easily recognizable by the large, chocolate-brown, triangular spot at the costal margin of the fore- 

 wing. Very common and widely distributed from Mexico to the Amazon. 



Th. ufentina Hew. (15tig) is above considerably more extensively coloured in a radiant, metallic KJiiilUia. 

 greenish-blue with a scent-spot in the cell. Beneath the forewings are quite brown with a lilac reflection, the 

 hindwings have a large, brown spot in the basal costal-marginal part. Sao Paulo. 



Th. viceta Hew. (156 g) has almost quite brown forewings and a very small scent-spot, only the proxi- vinia. 

 mal margin exhibits a narrow blue tinge, the hindwings are more extensively blue. Beneath like the preceding, 

 only the brown costal-marginal spot is larger, and at the costal-angle there is also a brown spot. Amazon (San- 

 tarem). 



Th. opalia Hew. (156g, h) is above somewhat more extensively blue than the preceding, beneath "ixiHn- 

 <[uite purple-l)rown with white macular rows. Described from the Amazon. 



Th. verania Hc/c. ( 156 h) initiates another subordinate group of mostly smaller species, which is like- ra-iinid. 

 wise closely allieil to echlun-, the copper-brown basal spots of the hindwings beneath are here partly united 

 with the proximally displaced postdiscal. verania is above radiantly light blue with a very narrow, black distal 

 margin and a but slightly tiroader apex, without a scent-spot. On the hindwing beneath the 2 usual, orange-red 

 anal-spots are absent. Amazon, Ecuador and Bolivia. 



Th. fabulla Hew. (156 h) resembles philinnn (156 h) above and has likewise a doul)le scent-spot, the jubuUa. 

 proximal lower part of which little contrasts with the brownish-black ground, the upper part being smaller 

 and lighter grey. Beneath on the hindwings almost like verania, only darker brownish-grey, on the forewings 

 with a straight, brown-red postdiscal band; in the anal angle we do not notice the distinct W of the said species, 

 but only a triangular, brown-red spot; at the anal angle and between the tails 2 orange spots. Guiana, Vene- 

 zuela, Amazon. 



Th. dolium Hew. greatly resembles the preceding, more purple blue and duller, with an only single (hiliunt. 

 scent -spot at the cell-end-beneath lighter, the copper-red sjDots bordered with a more distinct white. Honduras. 



Th. ceglusa Hew. (156 h) is above more extensively blue with a small, indistinct, brown scent-spot cculusa. 

 behind the cell and a small red anal spot. The under surface is very much like that of fabulla. Amazon. 



Th. petilla Hew. (156 h) has much more extensively blackish-brown forewings which are blue only pdiUa. 

 at the proximal margin, without a scent-spot. Hindwings lustrous greenish-blue. The under surface has a 

 reddish or lilac tinge, the distinct, brown, submarginal, small lunular spots are on both sides bordered by white, 

 the spots of the hindwings arranged about as in jahiilht. but larger, the red anal spots large; on the forcwing 

 the postdiscal band is longer and more parted into small spots, the uppermost of which at the costal margin 

 is quite isolated. Amazon. 



Th. phobe Godm. <£■ Salv. (156 h) is discernible from the preceding by the red-lirown colour being pholw. 

 on the hindwings much more extensive and flown together and reaching almost to the margin. Mexico, Guatemala. 



Th. velina Hew. (156 i) likewise greatly resembles the preceding, but here the red-brown is still more vdina. 

 extensive and reaches as far as near the base of the hindwings, the ground-colour being lighter, almost whitish. 

 Amazon. 



81. Dindynius-Group. 



Th. dindymus Cr. (= sphinx ^ Godt.) (1561) is allied to the .s-o/jAoc/e.s-group by tJic under surface, diudi/uius. 

 Init above it is extensively l)rilliant blue, without a scent-spot, with a but little brownish-black apex. Beneath
