FOSSIL PARASITIC HYMENOPTERA FROM BALTIC AMBER. 343 



length, almost twice as long as thick; following narrower and shorter, 

 tenth and eleventh submoniliform; apical joint narrower and one- 

 half longer. Thorax above strongly convex, the pronotum shagreened, 

 but the mesonotum and scutellum nearly smooth. Seen from above 

 the mesonotum is slightly longer than the pronotum. Parapsidal 

 furrows distinct posteriorly, but indistinctly marked on the anterior 

 half of the mesonotum, meeting the scutellum a considerable distance 

 external to the basal fovese of the latter. Scutellar foveas deep, but 

 not large; connected by an impressed line along the base of the scutel- 

 lum. Metanotum short, rounded on its posterior crest; with a lateral 

 carina both above and on the posterior slope, but otherwise without 

 sculpture, except for a faint transverse or oblique aciculation. Meso- 

 pleura large, sparsely punctulate, its discal fovea large and deep, 

 placed near its upper posterior angle. Pro- and metapleurse sha- 

 greened or faintly aciculated. Abdomen short and stout; second 

 segment longest, the following gradually shorter. Legs stout, the 

 anterior femora twice as long as broad ; middle and posterior tibiae not 

 thickened, smooth. Tarsal claws apparently each with a single long 

 tooth beneath near the base. Wings fully developed. Stigma two 

 and one-half times as long as broad; median cell slightly shorter than 

 the submedian; discoidal cell trapezoidal, the proximal lower side 

 fully twice as long as the apical lower side; cubital cell but little 

 shorter and narrower than the radial which is broadly rounded at the 

 tip as in the preceding two species. 

 One specimen, without number. 



Family DRYINIDiE. 



Dryinus filicornis sp. nov. 



9 . Length 6 mm. Head large, with the front slightly concave, 

 seen from above somewhat more than twice as wide as thick. Ocelli 

 large, very close together in a small triangle. Occiput with a strongly 

 carinate marginal line which extends to the temples. Eyes bare. 

 Palpi moderately elongate, but not preserved so as to show the num- 

 ber of joints present. Antennae 10-jointed, very slender and greatly 

 elongated, somewhat exceeding the body in length. Scape short and 

 thick, one-half longer than the second joint which is three times as 

 long as thick; third very long, six times the length of the second and 

 equalling the width of the head; fourth almost half longer than the 

 third; fifth and sixth growing shorter, each little more than half the
