192 THE ENTOMOLOGIST. 



11 kils. from San Jose, produced a female of this species ; this being 

 the only specimen I have, for, though we occasionally saw what we 

 believed to be the same butterfly flying over the flowers of tall forest 

 trees, we never succeeded in netting one. 



P. pandion, Feld. — This butterfly, which must be very closely 

 allied to P. anchisiades, Bsp., occurred at San Jose, in July. It was 

 not common, and I only seem to have got one specimen. 



P. branchus, Doubld. — One female taken at Limon in August is 

 all I have of this species. 



P. mylotes, Gray. — The commonest of all the Papilios in the low- 

 lands, especially at Guapiles in April and May. I took a good many 

 specimens there, and a few at Limon. 



Daptonoura isandra, Boisd. — Only seen at Limon in August, 

 flying in some numbers round a flowering shrub, but very restless 

 and difficult to catch, besides which all those that were netted were 

 in poor condition. 



Tachyris ilaire, Godt. — Occurred at San Jose in June and July, 

 but was not abundant. 



Pieris josepha, Godm. & Salv. — Only occasionally seen at San 

 Jose ; but was very common at Bio Grande on July 27th. 



P. elodia, Boisd. — Common at Cartago and all round San Jose 

 throughout the summer. I found a batch of Pieris ova one morning 

 when we were gathering water-cresses for luncheon in an elevated 

 meadow near Cartago, from which I eventually bred half a dozen 

 specimens of this butterfly. Their fresh supplies of food-plant used 

 to be purchased in the market at San Jo'se. The full-grown larva is 

 rather like a green centipede to look at superficially, as it has an 

 oily appearance ; in colour it is dull, pale green, ringed regularly 

 with darker green from head to tail. 



P. calydonia, Boisd. — Common, but quite passe, at Kio Grande, 

 July 27th. 



Terias albula, Cram. — Fairly common at Limon and Guapiles. 



T. delia, Cram. — Common at San Jose ; also taken at Guapiles. 



T. neda, Godt. — At Limon, San Jose, and Guapiles, but not very 

 common. 



T. euterpe, Menet. — Only fairly common. I have two males from 

 Cartago in May, also a male and female from San Jose, the former 

 of which is very grey on the under side of the hind wing. 



T. ivestwoodii, Boisd. — Common all round San Jose, flying along 

 the damp, grassy lanes throughout the summer. A magnificent form. 

 The female was comparatively scarce. 



T. damaris, Feld. — This lovely Terias was very common at San 

 Jose in June and July, and the females were more easily to be met 

 with than were those of the preceding species. 



T. xanthochlora, Koll. — Very scarce, only taken rarely in one 

 locality near San Jose ; and I have also one specimen from Guapiles. 



T. mexicana, Boisd. — Very common at San Jose, also taken at 

 Cartago in May ; the females were not very scarce either. 



T. proterpia, Fabr. — This exceedingly beautiful butterfly occurred 

 somewhat rarely near San Jose ; but it seemed to be fairly well 

 represented in the great crowd of butterflies at Bio Grande.
