Publ. 12. I. 1920. THECLA. By Dr. M. Dratjdt. 769 



Th. ligurina Hew. (152 e) is deep steel-blue with a purple tinge, with a small brown scent-spot Ugurina. 

 at the cell-end, the $ greyish-blue with dark-brown, broader margins. Beneath ashy-grey, forewings without 

 any markings, hindwings marked as in the preceding species, but the proximal band at the costal margin is 

 placed more towards the base. Mexico to Panama. 



Th. chlamys Drc. (152 g). Above like the preceding, but with a red-spotted anal lobe; beneath more chlamys. 

 reddish, the red spots of the hindwing less developed, and the proximal white line less sinuous. The 5 is above 

 brown, in the disc greyish-blue. Paraguay. 



Th. lyde Godm. d) Salv. (152 f) is above metallic indigo-blue, the broad black apex and the narrow lyd^!. 

 distal margin gradually pass over to the blue colour. The scent-spot at the cell-end is rather large, brown, 

 bordered by an elevated, metallic greenish-grey ring; the anal lobe of the hindwing without any red. The $ 

 is only little duller blue. Beneath ashy-grey, marked like the preceding species. Mexico to Panama. 



Th. ergina Hew. (= ela Hew.) (152 e) is somewhat larger, otherwise above like lyde, also beneath ergina. 

 alike, only more faintly marked, but of a light brownish ground-colour; the red spots of the hindwings larger, 

 their black pupil smaller. Surinam, also from Jamaica. 



Th. voltinia Hew. (152 k) is still larger, above deep indigo-blue with a greenish lustre and a large, voltinia. 

 roundish, browai scent-spot with a greenish slate-colour floating round it, on the anal lobe a reddish spot; 

 beneath darker broAvn than ergina; the two submarginal macular bands are closer together. Brazil, Bolivia. 



Th. buccina Drc. (152 h) differs above from the preceding by a deep steel-blue colour, similarly as bucdr.a. 

 in ligurina, and an entirely circular scent-spot; the ground-colour beneath is a warm red-brown, the two white 

 lines of the hindwing are still closer together. Brazil. 



Th. zebina Heiv. (152 f as zelina) is also in the (^ above bluish-grey with a roundish dark scent-spot zehina. 

 and dark spots before the distal margin of the hindwing; anal lobe with red spots. The 9. is above lighter, between 

 the tails also above wdth a red, black-pupilled spot. Beneath light brownish-grey, on the hindwings similarly 

 marked as in the preceding species, but the white lines are more remote from each other, the orange-red spots 

 are very large and between them there is bluish-grey dusting; the forewings likewise exhibit 2 white, ante- 

 marginal macular lines. Mexico to Nicaragua. 



Th, guadala Schs. is allied to brescia (152 f) and seems also to approximate zebina; I only know it guadala. 

 from the description : above distinguishable by the metallic steel-blue colour, the black scent-spot at the cell-end 

 being somewhat oval, the anal lobes likewise spotted in red. The $ is in the basal third bluish-grey, distally 

 blackish-brown; hindwing at the distal margin spotted in black, anal lobe red. Beneath dark grey, marked 

 like brescia. Mexico (Guadalajara). Expanse of wings: (J 30, $ 28 mm. 



47. Cupentus-Group. 



Th. cupentus Cr. (= annulatus(?meZ.) (154 d) has the same scent-spot as ^yt^e (152 f) and its allies, cupenius. 

 but it is larger here and placed nearer to the base by the very short cell. The forewings are above brownish- 

 black, proximally strewn with metallic blue. The under surface is brown with white transverse bands and 

 on the hindwing a white discal streak forming a sling with the proximal band; between the tails an orange- 

 brown, black-pupilled spot. Distributed from Nicaragua to Brazil, mostly common. 



Th. comana Hew. (= peralta Mschlr.) (154 e). The c? is above greyish-blue with a slight lilac lustre comana. 

 and a broad black apex; scent-spot double, obliquely overlapping each other as in thyesta (152 g), beneath 

 dark-brown, distally reddish-brown. The $ is brown, towards the base with a slight greyish-blue tinge with 

 a red, above white-pupilled spot at the anal angle and proximally fine white, black marginal line. Beneath 

 quite similar to cupentus (154 d), yellowish-brownish, on the hindwings with a lilac shine. On the forewings 

 the proximal band extends only as far as the lower median vein and grows narrower costally; on the hindwings 

 the red spot between the median veijis is removed more inwards; all the markings are more indistinct, more 

 blurred. Brazil. 



Th. cambes Godm. & Salv. (154 e) is rather similar, above the pale lilao-blue is very much reduced. ramhc.<!. 

 on the forewings confined to the basal inner-marginal part; the fringes, jjarticularly on the hindwings, are more 

 rusty-brownish. The lower part of the scent-spot is oval, jet-black, the upper part very small, aboiit ei-es- 

 centiform, brownish-grey, both parts embedded in a greyish-blue scaled ring. Beneath very much like comana, 

 easily recognizable by the broad, lilac-white dusting of the costal angle of the hindwing; on the forewings the 

 postdiscal white band is united with the proximal submarginal band on the lower median vein. Mexico, ( Jalapa), 

 Guatemala. 



Th. molena Jones (154 e). The rj is above subdued dark metallic blue, the distal margin and apex Diolena. 

 of the forewing broad black; in and behind the cell is a large oval, black scent-spot, parted by the blue trans- 

 verse vein; anal lobes of the hindwings red. The under surface is browTi with a lilac shine on the hindwings
