328 BRUES. 



In addition there are a large number of specimens which are not 

 perfectly preserved and as these could be better studied in connection 

 with more extensive material, they are not considered in the present 

 paper. The types of the new species are in the University Museum, 

 Konigsberg. 



Family EVANIIDiE. 



Oleisoprister preevolans sp. now 



9 . Length 12 mm. Ovipositor at least as long as the body, its 

 tip not being preserved in the type. Head seen from above nearly 

 quadrate, but distinctly broader than thick antero-posteriorly. Ocelli 

 large, close together; the anterior one separated from the lateral ones 

 by one-half its own diameter; lateral ones equidistant from each 

 other and from the eye-margin. Eyes oval, one-third longer than 

 broad. Malar space equal to one-third the eye-height. Antennae 

 inserted midway between the vertex and the tips of the closed man- 

 dibles; 14-jointed; scape stout, twice as long as thick, one-half longer 

 and twice as thick as the pedicel which is nearly twice as long as thick; 

 first flagellar joint a little more slender, and twice as long as the pedicel; 

 two following each one-third longer; others growing shorter to the 

 apex; the last being half as long as the first flagellar. Maxillary palpi 

 5-jointed; last three joints slender and equal, the second shorter and 

 much thickened; labials 4-jointed, joints except the longer basal one, 

 about as broad as long. Mandibles triangularly acute, edentate. 

 Pronotum without lateral tooth or tubercle. Mesonotum slightly 

 produced at the humeral angles into a very blunt tooth; coarsely 

 transversely grooved, there being about nine ridges; parapsidal 

 grooves very deep, converging at the deep basal scutellar fovea. Pro- 

 podeum coarsely irregularly reticulate, strongly constricted on a level 

 with the surface of the mesonotum and scutellum. Abdomen as long 

 as the thorax; viewed from the side, the first segment is funnel-shaped, 

 as long as high at apex; following segments growing shorter. Pleura; 

 more or less reticulated, the propleurae and pronotum smoother, punc- 

 tulate, except the anterior margin of the latter. Legs slender; longer 

 spur of middle and hind tibiae each as long as the breadth of its tibia 

 at the tip. Tarsal claws with three teeth, including the apical one, 

 and with a slight trace of another near the base of the claw. Wings 

 hyaline (as preserved). Stigma oval-lanceolate, nearly as wide as the 

 length of the first section of the radius ; median and submedian cells of
