BUTTERFLY COLLECTING IN COSTA RICA. 219 



E. nigricauda, Mabille. — Bred on a coarse kind of grass, from an 

 ovum I saw laid by a wild female at Limon in April. The full-fed 

 larva is a rich russet-brown, with a row of seven white dots on either 

 side. The head is shiny black. 



Achlyodes ozotes, Butl. — Fairly common at San Jose in June and 

 July. 



Antigonus nea/r chats, Latr. — Taken only at Limon in April, and 

 again in August. 



Eantis ('?). — A large dark brown velvety species, which is well 

 represented at South Kensington, but appeared to be at present un- 

 named. I have one from Limon. 



Thanaos clitus, Edw. — This pretty white-fringed " skipper " was 

 very common at Santo Domingo in June and July. 



Pellicia bipuncta, Schaus. — One specimen from Limon in 

 August. 



P. nyctineme, Butl. — Also only one specimen from Limon in 

 August. 



Systasea erosus, Hiibn. — One specimen from Limon in April, and 

 one from Eio Grande in July. Several others were seen. 



Chiomara mithrax, Moschler. — One specimen from Limon in 

 April. 



Cocceius pylades, Scudder. — Two specimens from San Jos6 in 

 June and July. 



Xenophanes tryxus, Cram. — One from Limon in April, and one 

 from San Jose in July. Several others were seen. 



Theagenes hamatospila, Feld. — One worn female from Limon in 

 April. 



Carystus cynaxa, Hew. — The larva of this " skipper " feeds on the 

 palm-leaves, and I occasionally came across it while looking for the 

 larvae of Opsiphanes crameri at San Jose. I have three specimens 

 bred from larvae, and one from a pupa found by Mr. Alan Wood. 

 Both are white and chalky in texture. 



Atames sallei, Feld. — One from San Jose in July ; no others 

 observed. 



Mylon zephus, Butl. — One from San Jose in July ; few others 

 were seen. 



Heliopetes laviana, Hew. — Fairly common at Santo Domingo in 

 June and July. 



H. arsalte, Linn. — Males very common at Limon in March, April, 

 and August. One specimen (a female) from San Jose, the only female 

 I have, and the only specimen I took in that locality, where this 

 butterfly was decidedly scarce. 



Hesperia syrichtus, Fabr. — Common all over. 



Before concluding these notes, I should like to express my grateful 

 thanks to Mr. N. D. Riley, and also to Mr. W. Schaus, for the very kind 

 help they gave me in the somewhat difficult task of identifying my 

 specimens in the National Collection at South Kensington.
