nearly touching the eye-margins and not much more than their own 

 diameter from the slightly rounded occipital margin ; face no longer than 

 wide and not produced upward beyond the eyes as in Coclopencyrtus, 

 although strongly concave lengthwise above the antennae. The latter 

 inserted slightly further apart than in the female although hardly 

 higher up on the face, somewhat longer than in Coelopencyrtus, not 

 clavate, but with the first four funicle joints shortly ramose on the inner 

 side; scape much longer, not triangularly thickened but on the contrary 

 rather strongly compresesd and somewhat dilated below, with a groove 

 on the outer surface to receive the pedicel; the latter triangular and no 

 longer than wide at apex, the first funicle joint longest, the last two 

 but little shorter, the first four much wider than long, being produced 

 on the inner side into moderately long rami, of which the third is long- 

 est, the first shortest; last two funicle joints subtriangular, narrow at 

 base and somewhat wider at apex than long; club solid, oval, no wider 

 than the preceding joint and a little shorter than the last two funicle 

 joints combined. 



Sculpture similar to that of Coclopencyrtus male, but the area above 

 the antennal sockets not nearly so distinctly dififerentiated, being ex- 

 tremely finely lineolate ; on each side of the middle of the face contigu- 

 ous to these areas is a lunulate or subangular impression where the sep- 

 arate curvatures of the lower and upper parts of the face meet ; these 

 impressions are highly polished and shining and are separated medially 

 by a smoothish, slight ridge, which widens a little above but soon be- 

 comes obsolete. Pubescence about as in Coclopencyrtus: the pedicel 

 shortly, rather densely pubescent on the upper side, the following joints 

 with much longer, rather abundant pubescence, which is also present on 

 the rami. 



Genotype: Adelencyrtus I'aalae Ashmead. 



This genus is only remotely related to Adelencyrtus in 

 which Ashmead placed his species, and hardly resembles it 

 even superficially, although it must be remarked that Adelen- 

 cyrtus even at its inception was not at all homogeneous.

The male, hithertofore unknown, closely resembles the fe- 

 male except in the points brought out in the generic descrip- 

 tion.
