1907.] BUTTERFLIES OF THE FAMILY LYC^NID^. 607 



Thecla clepsydra, sp. n. (Plate XXXYI. fig. 10.) 



Male. Upper side uniform violaceous blue ; costa, apex, and 

 outer margins broadly dark brown ; a fine submarginal blue line 

 and some blue scales towards anal angle of hind wing. Cilia 

 concolorous with wings. An indistinct, slightly darker brown 

 patch, occupying the oi\ter half of the cell of the fore wing and 

 apparently bordered on its costal edge by a linear brand-like mark 

 which is only visible in certain lights. On the under side this 

 insect resembles T. odinus Godm. & Salv.*, but the ground-colour 

 is darker and the pale linear marking at the end of the cell of the 

 fore wing is absent ; the inner line on the hind wing is reduced 

 to a blue spot near the costa and the median line is sinuous, much 

 broken and less angulated, and the red anal patches are entirely 

 absent. The lobe is largely black, and there is a marginal patch 

 of blue scales between the lower median nervules. 



Expanse 1-| inch.

 fig. 18. 



Messrs. Godman and Salvin place T. lugubris Mbsch. as a 

 synonym, and T. cahiria Hew. must also be added, the types 

 being quite indistinguishable from many specimens before me from 

 Guiana, Colombia, and Santarem. 



The species varies considerably in size. 



Mr. Kaye has kindly lent me his type from Trinidad, which I 

 have no doubt is a female, and which does not differ in any way 

 from many specimens fi'om Central America and from Venezuela 

 before me. Mr. Kaye compares it with T. beon Cr., from which 

 it is of course quite distinct. 



Thecla aruma. 



Thecla aruma Hew. 111. Diur. Lep. p. 192, pi. 75. figs. 609, 610 

 (1877). 



Mr. Godman has specimens from Guiana (Roraima and Carimang 

 River) obtained by Whitely. 



As pointed out by Hewitson, the red spots near anal angle of 

 hind wing below vary a good deal in colour and are sometimes 

 nearly obsolete.
