this dark blue-green ; clypeus yellowish-green suffused with coppery ; tegulic 

 dark purple-blue ; upper part of metathorax suffused with blue ; abdomen (ex- 

 cept first segment) dorsally with the tegument golden suffused with rosy ; wings 

 perhaps a little darker. 



Habitat. — Guayaquil, Ecuador, Ma^-June, 1913 ( C. T. Brucs). 

 A very fine species, related to E. mussitans, and also to E. poly- 

 chrojua (Mocs.), but quite distinct. 



Bombus robustus Smith. 



Huascaray, Peru, Sept. 21, 191 1, 6,500 ft. (C. H. T. Toivnscnd). 

 This is typical robustus, as described by Smith. 



Bombus coccineus Friese. 



Matucana, Peru, June-July, 1913, 7,300 ft. alt. (Brues) ; Pacha- 

 cayo, over 12,000 ft. (Townsend). 



Bombus funebris Smith. 



Pachacayo, Peru, over 12,000 ft., March 27 (C. H. T. Tonmscnd). 



Melipona mimetica new species. 



Worker. — Length 10 mm. or a little over, robust; head, thorax and legs 

 black, lower part of clypeus and basal half of hind tibi?e obscurely rufous, 

 apical tarsal joints chestnut red ; head and thorax above with very pale 

 ochreous hair; sides of face with short white hair; pleura with a large patch 

 of fulvous hair above, white below ; tegulje ferruginous ; wings reddish ; abdo- 

 men brig-ht chestnut red, when the segments are extended to the utmost, a 

 basal black line is seen on second to fourth ; sides (but not dorsum) of apical 

 half showing black bristles. 



Habitat. — Guayaquil, May-June, 1913 (Brucs). 



Extremely close to the Brazilian M. pscudoccntris Ckll.. from 

 which it differs by the black face, the lack of black (or any other) 

 hair on the dorsum of apical part of abdomen, and the coarse black hair 

 fringing the smooth outer face of hind tibia. The color of the legs 

 is also very different, and the inner surface of the hind tibia in .1/. 

 mimetica is clothed U'ith a fine white pruinosity (not always very 

 evident) ; while the h»r on the inner side of the basitarsus is shining 

 orange-golden, varying to more dusky. Eight specimens of M. 

 mimetica were collected ; the specific name refers to the perfect super- 

 ficial resemblance to Ccntris tarsata Sm. M. fuscipcs Friese must be 

 a similar insect, but it is typically with ashy-fuliginous hair, with the
