parently to the base of the abdomen; extruded part of ovipositor 

 very long and slender and somewhat longer than the abdomen. 



Legs long and slender, much as in Homalotylus^ but the front and 

 hind femora are much less compressed and much narrower, the 

 hind tarsi are very slender and filiform, whereas the middle tarsi 

 and tibial spur are like Eomalotylus. Wings long and narrow, and 

 very similar to Homalotylus; submarginal vein nearly straight, not 

 enlarged distad, the setae on it very fine ; marginal as in Homaloty- 

 lus; stigmal and postmarginal veins moderately long and shorter 

 than in Homalotylus^ the stigmal enlarged at the apex, forming an 

 acute angle with the postmarginal and not parallel with the mar- 

 gin; marginal fringe very fine, short and dense; disk of wing with 

 a transverse infuscated band which is narrower and fainter than in 

 Homalotylus^ the apical half of disk clear and uniformly setose, the 

 base of disk nearly bare out to the infuscated band ; speculum nar- 

 row above and reaching to the base of the stigmal vein, broadening 

 below at middle of disk where it passes out of the infuscated band 

 and joins the nearly bare area at base of wing; costal cell bare ex- 

 cept for one row of fine setae next to the margin of the wing in 

 the apical third. 



Sculpture extremely fine and microscopic throughout ; the f ronto- 

 vertex dull from very shallow, close, thimblelike punctures; the 

 mesonotum somewhat shiny and smooth and with a delicate micro- 

 scopic reticulation ; the propodeum smooth and considerably polished; 

 the pleura with a more or less longitudinal reticulation coarser 

 than that of the mesoscutum, but the propleura and the mesopleura 

 anteriorly are equally finely striolate-reticulate ; abdomen slightly 

 more coarsely reticulate than the mesoscutum. 



Pubescence very fine and short, white or whitish, and apparentH 

 not very dense except on the metapleura and hind coxae, where 

 it is of the same type as in HoTnalotylus; the eyes almost bare. 

 Coloration mostly yellow, nonmetallic, the antennae yellowish with 

 the club apparently not paler. 



Male. — Not known.

Female. — Face with sparse glistening white pubescense, the setae 

 arranged in a row on the lateral margins of the prominence between 

 the antennal scrobes and evenly distributed on the face and cheeks 

 exterior to the scrobes ; pubescence of mesonotum almost all denuded 

 in the type, but apparently sparse, fine, and whitish; abdomen 

 nearly bare, but there are a few fine whitish setae on each side except 

 at base and apex; ovipositor sheaths with sparse appressed setae; 

 pubescence of legs and antennae also very fine and short. Nearly
