144 THE CANADIAN ENTOMOLOGIST 



SOME EUGLOSSINE BEES. 



BY T. D. A. COCKERELL, BOULDER, COLORADO. 



The Euglcssines are perhaps the mcst brilliant of all bees, 

 and appropriately, many of them seem to visit the magnificent 

 orchids of the South American forests. I have recently had oc- 

 casion to study some previously unnamed Euglcssines in the U. S. 

 National Museum, and the results are presented herewith: 

 Eufriesia purpura ta (Mccsary). 



I have a male from F. Smith's collection, labelled Euglossa 

 bridlei Lep., but it does not at all agree with the description of that 

 species, and is a Eufriesia, related to E. pulchra (Sm.). The locality 

 is S. Paulo, Brazil. It agrees well with E. piirpurata (Mocs.), 

 and is referred to that species. Mr. Meade-Waldo, to whom I 

 wrote concerning the matter, replied that in the British Museum 

 they had four specimens under E. brullei, "all with dark heads and 

 thorax, and abdomens varying from reddish-bronze to almost clear 

 green." He also objected to the reference to E. purpuraia, since 

 Mocsary's figure (which I have not seen) represented it as having 

 the "head, thorax and abdomen totally reddish-bronze." The de- 

 scription, however, as quoted by Friese, agrees with my specimen. 

 It is stated that the abdomen (excepting the first segment) is 

 "viridi- vel igneo-auratis," as in the British Museum so-called 

 bnillei. In my specim.en it shines copper-red and golden-green in 

 different lights. 



Euglossa subg. Glossura, n. subg. 



Mouth-parts extremely elongated, extending far beyond apex 

 of abdomen; scutellum bigibbous. Type Euglossa piliventris 

 guerin. Also includes E. ignita Smith. 



Euglossa piliventris Guerin. 



Bartica, British Guiana. May 17. (U. S. N. M.) I have one 

 from Maroni. 



Euglossa bicolor Ducke. 



Near Para, Brazil (Miss H. B. Merrill, U. S. N. M.). The 

 sides of the thorax and he last three abdominal segments are green. 



Euglossa mandibularis Friese, var. bernardina, n. var. 



Male. Face and front golden-green, vertex blue-green; 

 mandibles with a'minute, cream-coloured spot at base, and a larger 

 one on malar space; thorax and abdomen above shining greenish
