[139] HYMENOPTERA 145 



Type. Cat. No. 5519, U. S. Nat. Museum. From Muir Inlet, 

 June 12 (Fur Seal Commision). Two female specimens. 



ZELOTYPA ALASKENSIS sp. nov. 



Male. Length 2.5 mm. Polished black; first two joints of 

 antennae, tegulae and the legs brownish-yellow or honey-yellow, the 

 hind coxae basally, the clavate part of their femora, and their tibiae 

 apically, obfuscated ; wings hyaline, the veins brown. 



The antennas are fully as long as the body, 14-jointed, the joints 

 elongate, cylindrical ; the scape is slender and about as long as the 

 pedicel and the first joint of the flagellum united, or very slightly 

 longer ; the pedicel is scarcely longer than thick ; the first joint of the 

 flagellum is the longest joint, a little longer than the second and excised 

 beneath for more than half its length and appearing as if angulated 

 when viewed from the side ; the following joints are subequal, imper- 

 ceptibly shortening to the last, the penultimate being hardly four times 

 as long as thick, the last being one-third longer than the penultimate. 

 The front wings differ from the two previous species in having the 

 marginal vein and the submarginal cell of approximately equal length, 

 the marginal vein being a little more than thrice as long as the stigmal 

 or first branch of the radius. The petiole of the abdomen is a little 

 more than four times as long as thick, smooth or nearly so, but with a 

 few longitudinal carinae ; body of abdomen oblong-oval, smooth and 

 highly polished, the medial grooved line above extending only to the 

 basal third of first segment.
