FOSSIL PARASITIC HYMENOPTERA FROM BALTIC AMBER. 329 



equal length; cubitus arising only a very little below the middle of the 

 basal vein, the first discoidal cell therefore very large, its upper side 

 twice as long as its basal one; first recurrent nervure received nearly 

 one-half its length before the apex of the first cubital cell; second 

 recurrent nervure received slightly but distinctly beyond the middle of 

 the second cubital cell which is closed by a hyaline vein; second section 

 of radius four times as long as the first, ending just before the wing tip. 

 Posterior wing with one closed cell, the basal. 



One finely preserved specimen No. XXB1G97. 



This species approaches closest to the genus Oleisoprister Bradley in 

 general characters although the tarsal claws have only two long teeth 

 before the apex; these however, are longer and much more prominent 

 than in Semenovius and there is a trace of another nearer the base of the 

 claw. It might thus be regarded as intermediate between the two. 

 The first discoidal cell is very large.

9 . Length 2.5 mm. Probably black or very dark colored, with 

 clear wings. Head transverse, twice as broad as thick, the temples 

 narrow, viewed from the side, less than one-half the width of the eye ; 

 its surface smooth. Head completely and strongly margined behind 

 on the occiput, temples and cheeks. Eyes oval, rather strongly pro- 

 tuberant, one-half longer than wide and nearly touching the base of 

 the mandibles below. Ocelli large and prominent, the lateral ones as 

 far from each other as from the eye margin. Antenna 3 fully three- 

 fourths as long as the body ; inserted just below the middle of the head, 

 on a slight ledge, 18-jointed; scape twice as long and slightly thicker 

 than the rounded pedicel; first flagellar joint narrower, four times as 

 long as thick and as long as the scape and pedicel together; second to 

 seventh joints growing shorter to one-half longer than broad, following 

 quadrate moniliform, the apical one one-half longer and obtusely nar- 

 rowed at the tip. Mesonotum slightly rugulose, but quite shining; 

 very convex, with distinct but not very deep, crenulated furrows. 

 Sides of scutellum irregularly rugose; metathorax reticulate, with a 

 Well defined basal median, and a petiolar areola, as well as a number 

 of smaller, irregular lateral areolae. Abdomen slightly longer than 

 the thorax, sessile; first segment short, as long as the propodeum, ele-
