a distance about equal to their width at midlength ; in addition 

 there is in the Chapada female a dorsal antehumeral pale spot, 

 no trace of which exists in pyginaens; laterally pyginaeiis is 

 the paler, the obscure stripes on the sutures in the males of 

 pygmaeus and the Chapada female, being more obscure or 

 absent. 



Abdomen brown, shading out to black on the apical segments, 

 faded in dried material, apparently very similar to the male, 

 but the lateral markings on 8 and the homologous markings 

 on 7 not discernible; appendages pale (greenish yellow?), 

 dark at the extreme base. 



Material Examined: Bolivar, near Santa Marta, Colom- 

 bia, December 24 and 25, 1916, 27 males, 3 females, collected 

 by J. H. and E. B. Williamson, in Coll. E. B. W. (3 additional 

 males, same locality and date have been sent to Drs. Calvert 

 and Ris, and Mr. Campion) ; Bonda, Colombia, one imperfect 

 male, H. H. Smith, collector, cited by Calvert (Bio. Centr. 

 Amer.) ; the very teneral condition of this specimen explains 

 Dr. Calvert's description of the color of the head. The local- 

 ity where specimens were collected by J. H. Williamson and 

 myself is briefly described on page 8, A Collecting Trip to 

 Colombia, South America, Misc. Publ. No. 3, Univ. of Mich., 

 Mus. of Zoology, but the number of specimens captured is 

 there stated to be about 25, while the correct number is 33. 

 I think every specimen seen was captured. We spent prac- 

 tically the entire day of December 25 looking for this one spe- 

 cies with the result that we caught 25 specimens that day. 

 They were, always found resting on broad leaves at a slight 

 elevation, usually a foot or two from the ground, and in the 

 sun. Pygmaeus is a dull colored and, under the conditions we 

 observed it, a sluggish species.
