296 MANDIBULATA. HYMEXOPTEHA. 



Genus LII.— PHYGADEUON, Grcwenkoii^t. 



AntenncB moderate, of the male porrect, longer and generally more slender 

 than in the females, in which sex they are curved or involuted ; in both 

 sexes the basal joints are more or less elongated : head short, transverse, 

 rather narrower than the thorax: eyes ovate, prominent: thorax slightly 

 gibbous, or somevs^hat cylindric : metathorax occasionally with spines : scu- 

 tellum more or less convex, 3-angular, with the apex a little obtuse : winga 

 moderate : cellule 5-angular, rarely w^ith the outer nervure obsolete : abdomen 

 petiolated, of the male narrow, of the female oblong or ovate, slightly 

 convex, or a little depressed, the basal segment generally smooth, in some 

 species with 2 elevated lines, the petiole mostly obsoletely grooved : ovipo- 

 sitor exserted : legs moderate, sometimes a little thickened, at others rather 

 slender. 



Of this genus Gravenhorst remarks that it differs from Cryptus 

 in having the antennae, legs, and ovipositor moderate, the cellule 

 5-angular, the abdomen of the female oblong or ovate, of the male 

 narrower, the 1st segment with the petiole longer and narrower than 

 the anterior part, the surface smooth, &c. ; to which may be added, 

 the length of the basal joints of the antennae, and these organs are 

 in general longer and rather more slender in the males than in the 



females. 



§ I. Scutellum and abdomen black.
