FOSSIL PARASITIC HYMENOPTERA FROM BALTIC AMBER. 337 



nearly equal parts. Scutellum with no grooves or fovese, except the 

 lines separating the axillae. Propodeum somewhat hroader than long, 

 margined laterally and at the tip; also with a complete median carina, 

 and an oblique lateral groove on each side which connects the tip of 

 the median carina with the middle of each lateral half. The included 

 area thus formed is reticulate, while the rest of the propodeum and 

 part of the pleura? as well are shagreened. Mesopleura smooth. 

 Abdomen long, fully equal in length to the head and thorax together; 

 first segment short, quite sharply truncate at the base and sharply 

 declivous; following segments about equal in length. Legs moder- 

 ately thickened, the tibia? all rather slender, except the anterior ones, 

 and smooth, not at all spinulose. Wings rather short, but perfectly 

 formed, reaching to the middle of the abdomen. Two basal cells, the 

 posterior one (submedian cell) distinctly longer than the median on 

 the externo-median vein. Second discoidal cell very distinctly marked 

 except on the posterior side; basal vein attaining the submarginal 

 vein far before the stigma which is small, about twice as long as wide at 

 tip. Radial vein long, equalling the submarginal. The first discoidal 

 cell indistinctly indicated, the transverse cubitus meeting the radius 

 before its middle. 



One specimen without number. 



This species agrees very well with Calyoza Westwood, although 

 the stigma is quite distinctly narrower and the head so extremely long. 

 The striking form of the head will make it very readily recognizable: 



Protopristocera Gen. nov. 



9 . Head shaped as in Pristocera, but not coarsely punctate as in 

 that genus; margined posteriorly. Ocelli large in a small triangle. 

 Eyes oval, nearly contiguous with the base of the mandibles, pubescent. 

 Mandibles apparently with several teeth, the apical one acute and 

 much prolonged. Maxillary palpi 5-jointed; labials with two visible 

 joints and possibly a third basal one. Antenna? long, 13-jointed. 

 Pronotum nearly as long as broad, without any furrows or coarse 

 punctures. Mesonotum nearly one-half as long as the pronotum, 

 with two rather approximated parapsidal grooves which converge 

 posteriorly and a second, less distinct pair, laterally. Propodeum 

 margined and with several longitudinal carinse, sharply declivous 

 posteriorly. Abdomen subsessile, acuminate; second segment the 

 longest, wings fully developed. Marginal cell open at the apex; sub-
