brownish-grey, sometimes very large, sometimes very small. Just as common as echion. From Mexico to 

 South Brazil. — The northernmost specimens from Mexico, greppa Dyar, have an almost white under surface, greppa. 



Th. giapor Schs. (160 d). Above blue as crolinus, but with the double scent-spot of the preceding, giapor. 

 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 unknown to me, but it presumably belongs here. Only the 5 is known: above iostera. 

 brown, the forewings only at the proximal margin, the hindwings more extensively 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, postdiscally a row of large, red spots, forming a broken W at the proximal 

 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 Hew. (156 g) and its nearest allies we most appropriately combine with the ec/iion-group cydrara. 

 to which they exhibit many relations. Above almost like echion, 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 Avidely distributed from Mexico to the Amazon. 



Th. ufentina Heiv. (156 g) is above considerably more extensively coloured in a radiant, metallic vJeniina. 

 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- i-iceia. 

 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 Heiv. (156 g, h) is above somewhat more extensively blue than the preceding, beneath opalia. 

 c^uite purple-brown with white macular rows. Described from the Amazon. 



Th. verania Heiv. (156 h) initiates another subordinate group of mostly smaller species, which is like- lerania. 

 wise closely allied to echion; 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 broader 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 philinna (156 h) above and has likewise a double scent-spot, the fabuUa. 

 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, brDwn-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 doUum. 

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



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

 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 peiilla. 

 at the proximal m_argin, 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 bj^ white, 

 the spots of the hindwings arranged about as in fabulla, but larger, the red anal spots large; on the forewmg 

 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-brown colour being plwbe. 

 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 i-cUna. 

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

 Amazon. 



81. Dindymus-Group. 



Th. dindymus Cr. (= sphinx ^ Godt.) (156 i) is allied to the sofhocles-gvon-^ by the under sui'face, dindymus. 

 but above it is extensively brilliant blue, without a scent-spot, with a but little brownish-black apex. Beneath
