HENRY J. FRANKLIN. 325 



Wings. — Much like those of the queen and worker. 



Legs.— CosiSi, trochanters and femora with much 5'ellow hair; fore 

 and middle tibiae mostly dark ; hind tibiae with outer faces slightly 

 hairy, their fringes usually with more or less pale ferruginous hairs ; 

 hind metatarsi with long, pale ferruginous hind fringes. 



Dimensiofis. — Length : queen, 13i mm. to 15 mm. ; worker, 10 mm. 

 to 12 mm. ; male, 10 mm. to 12 mm. Spread of wings: queen, about 

 34 mm. ; worker, 22 mm. to 31 mm. ; male, 22 mm. to 27 mm. Width 

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

 to 8 mm. ; male, 4^ mm to 7 mm. 



Redescribed from three queens, seventeen workers and 

 seven males. 



Habitat. — Most of my records for this species are Califor- 

 nian, as follows : Santa Clara County, Lake County, Nevada 

 County, San Jose County, Mendocino, Sonoma County, 

 Palo Alto, Yosemite. I have seen one worker from Nevada. 

 It seems to be a common species in California, at least in 

 some localities. 



This species apparently has its closest ally in htintii, from 

 which it can be at once separated by the different coloration 

 of the dorsum of its abdomen. Edwardsii and vosnesenskii 

 are also closely related. From edwardsii it can be readily 

 separated by means of its dark corbicular fringes and by the 

 nearly straight hind border of its black interalar band and 

 from vosnesenskii by its strikingly different coloration. 



The species is a rather pretty one, the yellow pile being 

 very bright and contrasting sharply with the black.
