146 THE CANADIAN ENTOMOLOGIST 



Friese's type was merely an extreme example of the same race. 

 The specimens seen are from Costa Rica, with the following data: 

 male, Sixola Riv^er (Wm. Schaus); female, Pozo Azul. June 5 (M. 

 A. Carriker). 



Euglossa variabilis, var. hemichlora n. var. 



Female. Like the Costa Rica form just mentioned, but abdo- 

 men almost pure green, contrasting with the coppery thorax. The 

 small size (as compared with mixta) agrees. 



Hab.- — Paramba, Ecuador, April, from W. F. H. Rosenberg. 

 (U.S.N.M.) If we regard mixta and purpurea as species, hemi- 

 chlora is a colour-variety of purpurea; but if it turns out that Friese's 

 extreme purpurea form is specifically distinct from the Costa Rica 

 insect, then E. hemichlora will be the name for the series represented 

 by the Costa Rica and Ecuador specimens before me. 



Euglossa cyanura, n. sp. 



Female. — Length about 10 mm. ; like a small E. variabilis, 

 but head and thorax brilliant emerald green, abdomen splendid 

 purple-blue, green at base and apex; black tuft or fleck on scutellum 

 very large, extending from apex three-quarters of distance to base; 

 ocelli much closer together than in variabilis, the posterior ones 

 separated by a distance only equal to the diameter of one; labrum 

 very short, the dark spots nearly circular; punctures of mesothorax 

 sparser than in the Costa Rica purpurea. 



Hab.— Porto Bello, Panama, Feb. 24. 1911. (Aug. Busck; 

 U. S. N. M.) 



Euglossa charapensis, n. sp. 



Female. — Length about 12 mm.; like E. cordaia, but distinctly 

 larger and more robust; wings very brown; scutellum more densely 

 punctured, shorter in proportion to its width, less filled out at 

 sides posteriorly, and with the black tuft large and broad, extend- 

 ing as in E. c^yaw/^m; apical part of abdomen with very strong 

 copper-red tints. The face is distinctly broader than in cordata. 



Hab. — Rio Charape, Peru, Sept. 17, 1911, (C. H. X- Towni- 

 end). This may possibly be Friese's E. cordata var. aureiventris, 

 but Friese gives no particulars except that the abdomen is shining 

 golden-red, so his insect presumably has the structure of true E. 

 cordata. E. cordata extends right across South America; I have 

 it from Bahia on the east, and Ecuador on the west, . ;-:./•,
