29, while Ithomiines {Ithomia heraldica, see page 79, 

 Dircenna klugii, Episcada salvinia, very similar to E. apuleia 

 described on page 79 but a little larger, and Mechanitis 

 doryssus) were taken in shady lanes near this part of the 

 stream, a male of D. klugii was caught in bright sunshine and 

 two males and a female of this species were taken in bright 

 sunlight at Cartago on August 21. Ithomiines (the species 

 not recorded in our notes nor represented in our specimens) 

 were seen flying in bright sunshine both in the morning (11 

 A. M.) and about i P. M. of May 30, in the same general 

 locality, and in bright sunshine on a road above Tierra 

 Blanca on July 12. In this last case the country was open 

 for many rods on both sides of the road and the wind was 

 blowing strongly, which may account for this occurrence. 

 Of D. klugii we have four specimens, three males and one 

 female, expressly labeled as having been taken in bright 

 sunlight and four (three males, one female) labeled as having 

 been caught in the shade; on placing these in two parallel 

 rows for comparison, I could find no constant difference be- 

 tween the two lots. We also have two males of Ithomia 

 hippocrenis, a clear transparent-winged species with mark- 

 ings similar to those of Hymenitis oto, taken in sunshine, on 

 flowers, in a new road in the forest at Guacimo, on June 7; 

 our other specimens of hippocrenis from Guacimo and 

 Guapiles, are labeled "Forest," with no mention of shade or 

 sunlight. On December 4, on La Carpintera, the clear- 

 winged Episcada apuleia and salvinia were observed flying 

 both in shadow and in bright sunlight. We may conclude 

 that while the Ithomiine butterflies are chiefly to be found 

 in the shade they are not restricted to that condition. 



Three of the species of butterflies collected in the Reven- 

 tado region above Cartago on May 29 — Lycorea atergatis, 

 Mechanitis doryssus, and Melincea imitata — are so exceed- 

 ingly alike in colors and color-pattern, and not so unlike in
