SOME COSTA RICABf BEES. 



BY J. C. CRAWFORD, JR. 



The material on which this paper is based was for the most part 

 collected by the author in odd moments while doing other work in 

 1903. In all only about 400 specimens were taken. Some speci- 

 mens collected by Prof. L. Bruner and Messrs. Gary and Carriker 

 in 1902, as well as a few received from other people while in Costa 

 Rica, were examined, all these being properly credited. Those 

 having no collector's name after them were taken by the author. 

 In addition to the species mentioned in the paper, quite a number 

 of others were taken, which at present cannot be identified, among 

 them being about a dozen species of Melipona. 



The localities from which specimens were examined are as fol- 

 lows: on the Atlantic Slope, Guacimo (450 feet); Guapiles (1000 

 feet) ; Cartago (4450 feet) ; Volcano Irazu (9000 feet). On the 

 Pacific Slope, San Jose (3550 feet) ; Monte Redondo (about 4000 

 feet) ; Pozo Azul, on the Rio Grande near the Pacific Ocean. 



The types, except that of IHalictus costaricensis, have been depos- 

 ited in the National Museum ; cotypes have been given the Ameri- 

 can Entomological Society.

 Cartago (June). 



San Jose, June, on Dahlia. The most common species taken. 

 From Cartago (June) I received about one hundred workers. 



This is the species described as leucomelas Crawford and Swenk. 

 Dalle Torre has wrongly credited this species to Asia, as the type 

 came from Chiriqui, so the species was overhjoked and redescribed.
