ICHNEUMON-FLIES OF AMERICA I 1. METOPIINAE 9 



tinued dorsally between antennal sockets as a narrowly triangular 

 process which becomes a lamella at its dorsal end, the process reaching 

 about 0.4 the distance to median ocellus; temple moderately long, 

 convex; occipital carina absent or complete; cheek about 0.4 as long 

 as basal width of mandible; upper margin of pronotum not swollen 

 or specialized, with an indistinct submarginal impression; propleurum 

 moderately convex; scutellum large, a little transverse, with lateral 

 flanges that reach its apex; areolet present, large; nervulus beyond 

 basal vein by 0.18 to 0.35 its length; nervellus broken between its 

 lower 0.35 and upper 0.4; prepectal carina as shown in figure 164,a; 

 sternaulus represented by a rather strong, broad groove; metapleurum 

 completely covered with rather coarse close punctures; propodeal 

 carinae as in figure 164,a; propodeal spiracle short elliptic; suture 

 between second trochanter and femur of front and middle legs dis- 

 tinctly indicated; tibial spurs all present, the spurs of middle tibia of 

 equal length or the front spur a little longer; all tarsal claws with long 

 pectination; abdomen parallel-sided, strongly convex; first tergite 

 short and stout, its spiracle at its basal 0.25, its lateral longitudinal 

 carina absent, its median longitudinal carinae extending usually to 

 apex; second and third tergites and more or less of fourth tergite some- 

 times with a pair of median longitudinal carinae; epipleura vestigial, 

 narrow and thick; seventh and following tergites retracted in both 

 sexes; sixth sternite of female rectangular, unspecialized. 



There are three known species, one in eastern North America and 

 two in Japan. The three species are widely different from one another, 

 and Uchida has erected a genus for each of the Japanese species, as 

 noted in the generic synonymy. The generic description is based 

 only on P. hagenii and P. pilosus.

Front wing 9 to 10 mm. long. Face with broad weak irregularities 

 and close punctures of various sizes; occipital carina complete; man- 

 dible rather broad, unspecialized, its apical teeth of equal size; flagel- 

 lum long and slender; thorax with close punctures that are rather small 

 but strong; spurs of middle tibia of equal length; nervellus broken 

 near its upper 0.45; abdomen with coarse strong punctures, its second 

 and third tergites and more or less of fourth tergite with a pair of 

 median longitudinal carinae.
