HENRY J. FRANKLIN. 339 



Pile very long and rather fine. Face and occiput with yellow pile ; 

 thorax entirely clothed with yellow pile except for a broad black band 

 between the bases of the wings ; abdomen above with first segment yel- 

 low, second and third ferrjiginous-red, fourth and fifth yellow and sxth 

 black. Malar space niediutn. 



Queen. Head. — Face with a considerable amount of yellow pile 

 above and below the bases of the antennae ; occiput with yellow pile ; 

 sides of head entirely dark. Labrum with tubercle-like areas large 

 and not very widely separated, their summits slightly concave, smooth 

 and shining ; shelf-like projection rather small and narrow. Malar 

 space slightly longer than its width at apex ; about one-fourth as long 

 as the eye. Clypeus rather strongly punctate. Flagellum of antennae 

 about twice as long as the scape ; third antennal segment much longer 

 than the fifth, the fifth somewhat longer than the fourth. 



Thorax. — Anterior part of dorsum covered with yellow pile; center 

 of disc naked ; a broad black band between the bases of the wings 

 (about one-half as wide — from front margin to rear margin — as long 

 — from wing base to wing base); scutellum of ten with anterior median 

 portion covered with an extension of the black pile of the interalar 

 band, but sometimes entirely yellow. Mesopleura usually covered en- 

 tirely with yellow pile to the bases of the legs. Metapleura usually 

 entirely yellow. 



Abdomen. — Dorsum : segment one yellow ; segments two and three 

 ferruginous-red ; segment four mostly yellow, but with more or less 

 black pile in the middle ; segment five much like segment four, often 

 with more black pile in the middle ; segment six black. Venter rather 

 variable, usually with fringes on apical margins of segments mostly of 

 light hairs. Hypopygium without a median carina. 



Wings. — Not very deeply stained with brown ; the fore pair gener- 

 ally lightest across the median portion. 



Legs. — Coxas usually with some yellow pile ; trochanters bearing a 

 considerable amount of yellow pile on their lower sides ; femora, espe- 

 cially the middle and hind pair, with considerable yellow pile ; fore 

 and middle tibiae usually with no light or yellow pile ; corbicular 

 fringes usually black, but on some specimens with more or less ferru- 

 ginous hairs. 



Worker. — Clypeus inclined to be sparsely punctate, smooth and 

 shining ; sides of head usually black, but sometimes with a small 

 amount of yellow pile ; apical abdominal segment for most part black 

 above, but sometimes bearing a little yellow pile ; otherwise closely 

 resembling the queen. 



Male. Head. — Face with a large patch of pure light yellow pile 

 covering the greater part of the clypeus and extending upward beyond 

 the bases of the antennae, but not approaching the eye margins on 

 either side ; occiput with triangular patch of yellow pile ; ventro-lateral
