Female. — The same as c.arlylei carlyei but of the head only the 

 clypeus is yellow, the abdomen is dark brown, the legs are dusky 

 black except the knees, tips of tibiae and the tarsi, and the antennae

Achnjsocharella silma Girault, Two New Achrysocharellae, 1917, p. 1. 



Female. — Length, 1.20 mm. 



Differs from Derostenus punctiventris Crawford, in that there are 

 two ring-joints (funicle 1 is subquadrate and a little shorter than 2), 

 the scape is white at proximal half and the substigmal spot is much 

 more distinct, reaching nearly to the caudal wing margin. The body 

 is stouter and the cephalic tibia is black ventrad. Annulus near 

 base of middle and caudal tibiae, distinct. Parapsidal furrovrs 

 complete. Mandibles tridentate. Tj^pes compared. 



From one female, Gleimdale, Maryland, April, in the woods. 



Type. — Cat. No. 20827, U.S.N.M., the specimen on a tag, the head 

 on a slide. 



ACHRYSOCHARELLA PARTIAENEICEPS Girault. 



Achrysocharella partiaeneiceps Girault, New Eulophidae, 1917, p. 1. 

 Female. — A little smaller than BMcnopeltomyia carlylei and differing 

 from it as follows: The abdomen as in the variety j^oeta of that species; 

 the ocellar area and the upper half of the occiput are bright metallic 

 green (the ocellar area large, so that the vertex is metallic except a 

 narrow cross-stripe along the occipital margin and which connects 

 with a similar yellow line along the occipital edge of the eye) ; the 

 legs are golden yellow except the caudal coxa ; the propleurum is all 

 metallic; the antennae are yellow except the scape above and the 

 pedicel at base broadly; the two ring-joints are large, the pedicel 

 only slightly longer than wide; the funicle joints are subequal, sub- 

 quadrate ; the terminal nipple of the club is minute and like a "bud, " 

 not spine-like and distinct; and the post-marginal vein is distuictly 

 longer than the stigmal, subelongate (both veins short in carlylei, the 

 postmarginal very short). Parapsidal furroM's complete. Mandibles 

 trideiitate, apparently not finely serrate within as in carlylei.
