The species is like a Zooencyrtus except the "shorter club in 

 that genus. It may represent a new group. Aphidencyrtus 

 Ashmead may be retained as a group distinct from Ilahrolepoidea 

 only on the ground of a difference in mandibular shape.

Habrolepoidea tarsalis, new species. 



Female — Length 1.10 mm. 



Like depressa but differing as follows: The scape is cylindrical, 

 slender, the vertex not thin (cephalo-caudad), the form is narrower 

 (moderate in width), the thorax convex, the postmarginal vein 

 somewhat shorter than the stigmal, the scutellum finely longi- 

 tudinally lined, the abdomen shorter, its oxipositor not extruded. 

 Like aphidiphagus Ashmead but the mandibles with the third 

 tooth acute, the scutellum with very fine longitudinal striation 

 (instead of fine scaliness) and the venation is different. Funicle 1 

 a little longer than wide, 2 a half longer than wide, longest, 6 

 as long as 1 but wider. Club two-thirds or more the length of the 

 funicle. 



Described from two females in the collection of the U. S.
