Stigma lanceolate; the radius arising near its basal third, first abscissa 

 of radius less than lialf as long as the width of the stigma, one-fifth 

 the length of the second, second abscissa one-half longer than the first 

 transverse cubitus, a little less than half the length of the <iiird abscissa; 

 recurrent nervure joining the second cubital cell, which is five-sided. 



Second tergite finely longitudinally aciculate antero-lati>rally ; suture 

 between the connate second and third tergites evident, usually finely 

 crenulate, the highly polished median triangular area of second tergite 

 separated from the lateral areas by imperfectly defined, percurrent, 

 feebly aciculate, diverging impressions; third tergite smooth and highly 

 polished ; second and third tergites subequal in length, the third widest 

 and three times as broad as long; ovipositor exserted, nearly oiie-half 

 tlie length of the abdomen. 



$ The sculpture of the abdomen in the males varies greatly ; some 

 have the second and following tergites smooth, the suture of the second 

 and third tergites not evident, not at all crenulate, while in others the" 

 entire second tergite is aciculate. Antennae 20-24-jointed, usually 22 

 or 23.

Idns I'liiis ill (Jaliau's earefnlly elaborated t;il)l('s of the 

 Xorth American species of Opius (Proc. U. S. Xat. ]\[u^\ -i-l> : 

 (58-T2 ) to Opius osriiiidis (Ashmead) known only in the male 

 sex from material bi'ed from an Oscinis lireedinii; in the leaves 

 of Planfago niajm- at Washington, D. C Our species differs 

 but little in the characters given in Ashmead's description. 

 The suture at the base of the scntellnm is certainly not innate 

 in our s])('('ies. nor are the lower part.s of tln^ head (except the 

 mandibles and the (dypens) yellow. Doubtless our species is 

 distinct and more diiferences will b(^ found when the ? of 

 oscinidis is studied.
