rather long and forming distinct, though weak, corbiculae. Hind 

 metatarsi about three times as long as their greatest width. 



Diviensions. — Length: queen, 17 mm. to 19 mm. ; worker, 11 mm. 

 to 13 mm. ; male, 13 mm. to 15 mm. Spread of wings : queen, 41 mm. 

 to 46 mm. ; worker, 28 mm. to 31 ram. ; male, about 32 mm. Width 

 of abdomen at second segment : queen, 9 mm. to 10 mm. ; worker, 6 

 mm. to 7 mm. ; male, nearly 7 mm. 



The queen is here redescribed from four specimens and 

 the worker from two. 



Variatio7i. — Two workers (from Venezuela) before me, 

 evidently belonging to this species, differ considerably from 

 the typical worker in the coloration of the abdomen. These 

 workers may be described as the following : 



Color Variant. —Like typical worker, but with dorsum of abdomen 

 all dark fuliginous, except the rufo-ferruginous pile on the anterior 

 angles of the first segment and a considerable patch of the same color 

 on the fourth segment ; dorsum of thorax also with a noticeable ad- 

 mixture of very dark brown hairs, mostly between bases of wings and 

 in front ; occiput and sides of head dark fuliginous, without an ad- 

 mixture of ferruginous pile ; face with a mixture of dark and ferrugin- 

 ous pile, neither color being noticeably predominant. 



There is also before me a male received from H. F'riese 

 and labelled by him " Bombjcs bicolor,^' which varies some- 

 what from the typical male above described. This specimen 

 may be described as follows : 



Male Color Variant 1. — Like typical male above described, but with 

 dorsum of thorax, between bases of wings, strongly shaded with dark 

 pile (this dark pile being intermixed with the rufo-ferruginous pile) 

 and with dorsum of abdomen bearing pile as follows : Segment one 

 dark, except for some ferruginous pile admixed on anterior corners ; 

 segments two and three entirely black ; segment four rufo-ferruginous 

 in middle, but black on extreme sides ; segment five black on extreme 

 sides and in very middle, but otherwise covered with rufo-ferruginous 

 pile; segment six almost entirely black, but with a faint sprinkling of 

 whitish hairs on extreme sides ; segment seven cinereous. The speci- 

 men was collected in Peru (Callanga). 



Habitat. — We have the following valid records : Colombia, 

 Mexico (Colon), Venezuela, Ecuador (Cuenca, about 7,000 

 feet altitude) and Peru. Some of the queens before me are 

 from Colombia and some from Venezuela and the typical 

 workers before me are from Colombia. This is a handsome
