656 Dr. G. B. Longstaff's Bionomic Notes on Butterflies. 



Caracas, Venezuela, 3 March, 1907. The dingy little 

 Catochrysops hanno, Stoll., was seen sitting head 

 downwards, opening its hind-wings at intervals. 



Walderston, Jamaica, 16 February, 1907. Calycopis pan, 

 Drury. The lobe of the hind-wing is everted as in 

 AphnsBUS, Argiolaus, etc. 



St. Ann's, Trinidad, 1 April, 1907. A [$ of Thecla 

 spurius, Feld., seen sitting head down; the hind- 

 wing is folded ; the lobe is large. 



The Zebra-like Thecla linus, Sulz., is a common species 

 in Trinidad. The lobe of the hind-wing is everted, but 

 not quite to a right angle ; it is curious that the tails are 

 crossed, so that the tail of the right-wing imitates the 

 antenna of the left side and vice versa. Mr. Knight has 

 made this very clear in the figure. 



Fig. 1. 



Thecla linus at rest : (a) natural size ; (6) the lobe enlarged. 



The tails were seen to move slightly, and the "false 

 head " looked more like a head than the real one. Though 

 I have no note to that effect, I feel sure that I saw this 

 species sitting head downwards. 



My recent Ceylon experience (Jan.-March, 1908) 

 enables me to add 9 more species, in which I have 

 observed the inverted attitude, making in all 19 species of 

 Lycmnidm. It seems probable that sufficient observations 

 are alone required to prove the habit to be general in that 

 family.* 



* Compare Trans. Ent. Soc. Lond., 1905, pp. 85, 86, 127. Mr. 

 Marshall writes : " I am quite satisfied that this (head down) is the 

 usual position in Lycaenidx, and could add numerous species to your 

 list, such as : Aphnaeus, Spindasis, Axiocerces, lolaus, Stugeta, Hypo- 

 lycsena, Mimacreea, Nyrina, etc., etc., but the simplest way is to 

 mention the species which do not do it. Of these I know three 

 only in South Africa : viz. Alsena nyassas, A. amazoula, Sind Pentila
