as yellow, the middle coxa infuscate basally, the hind coxa blackish 

 except at apex, and front and middle trochanters and apex of front and 

 middle coxae more or less tinged with pale yellowish. Sometimes 

 the ground color of the legs is brownish rather than fulvous.

5. Genus Heniiinetopius 



Figure 166,a 



Hemimetopius Benoit, 1955, Ann. Mus. Congo Beige, ser 8, vol. 36, p. 344. 

 Type: Hemimetopius kayoveanus Benoit; original designation. 



Front wing about 5 mm. long; front spur of middle tibia about 0.8 

 as long as hind spur; thorax in dorsal view pyriform, somewhat swollen 

 anteriorly; pronotum dorsally roundly curved toward its dorsal 

 margin, except that there is a broad, faint impression near its margin; 

 scutellum quadrate, a little wider than long, its lateral carina strong 

 and produced apically as in the genus Metopius; mesopleural suture 

 absent; posterior transverse carina of mesosternum complete, not 

 interrupted in front of the middle coxae (this carina incomplete in all 

 other Metopiinae); metapleurum with fine setiferous punctures all 

 over, without sharp wrinkles; second tergite with a sharp median 

 longitudinal carina, without a distinct sublateral carina; third tergite 

 with a fine sharp median longitudinal carina, without a sublateral 

 carina. Structure otherwise as described for Chorinaeus. 



This is an Ethiopian genus. Two species were described by Benoit 

 in 1955 and a specimen from Nigeria that appears to represent a third 

 species is in the U. S. National Museum. This specimen was used for 

 the generic description above and for preparing the figure. 



6. Genus Metopius 



Front wing 6 to 16 mm. long; body punctation coarse and strong; 

 face with most of its surface occupied by a flat or concave escutcheon- 

 shaped area that is bounded by a carina; interantennal process of 

 face variously shaped, according to the subgenus; temple moderately 

 short to very short, convex to flat; occipital carina present above, the 

 rest present or absent according to the subgenus ; cheek short ; mandible 

 with its lower tooth much smaller than its upper tooth or sometimes 

 lacking; flagellum moderately slender to thickened, often somewhat 

 flattened, long to rather short; upper margin of pronotum not thick- 

 ened or slightly thickened; propleurum moderately convex; scutellum 

 short, transverse, dorsolaterally with a winglike flange that extends
