THE TRIBE CHALCIDINI — BURKS 341 



ocellus, not ended ventrad of it, can usually be relied upon to dis- 

 tinguish the female of this species. 



Description. — Male : 2.5-3.5 mm. Antennae inserted dorsad of ven- 

 tral margins of compound eyes, apex of scape not quite reaching level 

 of posterior margin of anterior ocellus, pedicel equal to or slightly 

 longer than segment 4, ring segment one-third to one-fourth length 

 of pedicel, segments 4 to 8 equal, 9 and 10 slightly shorter, last three 

 combined equal in length to 7 and 8 ; scrobe cavity shallow ; frontal 

 tentorial pits usually visible just laterad of antennal bases ; width of 

 malar space two-fifths height of compound eyes ; combined widths of 

 compound eyes slightly greater than interocular space at level of apex 

 of interantennal projection; posterior ocelli separated from com- 

 pound eyes by a distance less than diameter of ocellus ; dorsal width 

 of head slightly less than maximum dorsal width of thorax. 



Prepectus minute, reaching tegula; apex of mesoscutellum with a 

 minute, mesally depressed lamina ; metepisternum with deep, scattered 

 punctures, dorsal ones slightly smaller than ventral ones ; metacoxae 

 minutely shagreened, outer surface also shallowly and irregularly 

 pitted; metafemur lightly shagreened, outer surface rather densely 

 covered with short pubescence, ventral margin with 14 to 17 teeth, 

 basal one only slightly larger than others ; obscure imier tooth present. 



Propodeum irregularly carinate, two shagreened or minutely retic- 

 ulated basolateral areas present, a minute tooth present at each pos- 

 terolateral angle, spiracles slanting slightly laterad; petiole two and 

 one-half to three times as long as wide, basal lamina minute, lateral 

 carinae present, but rather vague ; gaster equal to or slightly longer 

 than metafemur; eighth tergite very lightly shagreened, almost gla- 

 brous, sparsely setose, spiracles round; cerci oval, located near pos- 

 terior margin of ninth tergite ; penis valve (fig. 14, m) .
