basal segments yellow. Antennre brown throughout ; legs paler and more 

 yellowish. Wings rather strongly suffused with yellow ; veins and stigma 

 brownish-yellow. Head and pleurre subopaque, finely and densely punctate ; 

 elongate piligerous punctures on the cheeks and clypeus like those of the 

 worker major. Thoracic dorsum and gaster shining. 



Male. — Length 5-5.5 mm. 



Head and thorax densely and finely punctate and less shining than in any 

 of the preceding forms ; cheeks and gula, as well as the gaster and upper 

 surface of the head and thorax with rather long, scattered hairs. Black ; 

 antennal funiculi, tarsi and articulations of legs brown. Wings colored like 

 those of the female. 



The types are from the District of Cohtmbia. I have seen speci- 

 mens of all four phases from the following localities : 



Virginia: (Emery). 



New Jersey: Cumbridge County (H. Viereck) ; Lakehurst 

 (Wheeler) . 



Illinois: Urbana (J. L. Pricer). 



California: Los Angeles (Emery).

This variety, which I have failed to recognize among my speci- 

 mens, is described by Emery as follows : 



'■ A few workers from Washington, D. C. have the color and shin- 

 ing surface of nearcticiis. but a very few bristle-bearing foveolse on 

 the cheeks. A male accompanying these workers resembles ncarctlcns 

 more closely than subbarbatus. 



" Mr. Pergande writes me that this form always occurs on living 

 oaks, whereas the former occur only on dead trees."

Worker major. — Length 6.5-7.5 mm. 



Color the same as in rasilis. Antennal funiculi often infuscated towards 

 their tips. Surface shining, head more opaque in front, finely and densely 

 punctate ; mandibles, cheeks and clypeus with numerous elongate foveolje 

 bearing short, stubby hairs. Mesonotum convex, epinotal angle in profile 

 much rounded. Petiole thick, strongly convex in front, flattened behind, 

 upper border sometimes with a faint median impression.
