We place one Nearctic species, the Neotropic (Calliephialtes) 

 Anastelgis brasiliensis (Enderlein) 1919 (new combination), and three 

 undescribed Neotropic species in this genus. The European Ephialtes 

 gnathaulax Thomson 1877, the Japanese Ephialtes chui Uchida 1934, 

 and some undescribed species from Japan and China correspond in 

 most characters to the American species placed definitely in Anastelgis, 

 but have the outer face of mandible more strongly and completely 

 punctatostriate, and because of this and a different geographic distri- 

 bution it seems probable that they represent a different evolutionary 

 line, and are not congeneric with the American species placed in 

 Anastelgis.

Figure 330,b 



Front wing of male 6 mm. long, of female 7.6 to 10.5 mm. long; 

 mesoscutum with dense hairs all over; metapleurum with fine, rather 

 sparse punctures; propodeum polished, with sharp punctures laterally 

 and basolaterally; third and fourth tergites with sharp, rather small, 

 well-separated punctures ; ovipositor sheath about 1 .3 as long as front 

 wing.

 and pedicel ivory, blackish brown above; flagellum blackish brown; 

 palpi stramineous; thorax ferruginous, the tegula, hind corner of 

 pronotum, and vertical mark on prepectus ivory; upper part of pro- 

 pleurum, scrobe of pronotum, propodeum, and metanotum fuscous, 

 the propodeum with ferruginous stains; front and middle legs ivory, 

 the femora behind and apex of tarsal segments pale fulvous; hind leg 

 fulvous, the extreme apex of coxa, trochanters, apex of femur, and tibia
