Eab. Costa Eica ( Van Patten). — South Ameeica, Venezuela to Amazons valley x 2 

 and Guiana. 



We have a single male Costa-Eican example which formed part of Van Patten's 

 collection, no other Central-American specimen having come under our notice. The 

 species appears to be very common throughout the Amazons valley.

An abundant species in Guatemala in the lowlands on both sides of the mountain- 

 range up to an elevation of about 3000 feet. Southward it appears to become scarcer, 

 as we have no specimens from Costa Eica or Nicaragua, and only two or three indi- 

 viduals from the State of Panama. It does not appear to have any very close ally. 



We note a slight variation in the markings of the underside in different individuals, 

 chiefly as regards the colour of the spot between the median branches of the secondaries, 

 which varies from rufous to yellow, and there are a few other minor points. It does 

 not appear, however, that these differences are of specific value, as we trace their 

 transition from one form to another, and this without regard to locality. The difference 

 may possibly be attributed to seasonal broods. 



We figure a male from San Geronimo and a female from Chiriqui.
