Genus XLIII.— MICROLEPTES, Gravenhorst 



AntenncB stoutish, porrect, and curved at the apex in the males, curved and 

 thickened in the females, composed of about 22 joints, the basal one robust, 

 2nd minute, 2 or 3 following in the males subclavate, apical one elongate : 

 head subglobose : face slightly protuberant : eyes oval : thorax cylindric- 

 gibbulous : wings ample ; cellule wanting ; scutellum slightly convex : abdomen 

 oblong-ovate, somewhat clavate in the males, sujDported by a stoutish 

 peduncle, gradually increasing in width to its union with the basal segment 5 

 with a tubercle in the middle on each side: ovipositor concealed: legs rather 

 short and stoutish. 



This genus may be known from the foregoing by wanting the 

 cellule on the anterior wings, which are long and ample ; the abdo- 

 men arises from a slender peduncle, and is somewhat clavate, the 

 antennae long and slender, &c.
