NO. 1927. DESCRIPTIONS OF NEW HYMENOPTERA, 5— CRAWFORD. 173 



tions ; below with striae converging toward mouth ; antennae brown, 

 the scape and pedicel testaceous ; sculpture of postvertex medially less 

 reticulate than Tiunteri; mesonotum with thimble-like punctures on 

 the disk and outer margins of lateral lobes becoming rugulose; pro- 

 podeum finely reticulately lineolated, v/ith a median carina and a 

 transverse fold, the lateral folds not very distinct; legs dark brown, 

 the trochanters, knees, tibiae, and tarsi testaceous; abdomen longer 

 than head and thorax combined, slender. 



Male. — Length about 2.5 mm. Very similar to the female, the 

 sculpture of the face stronger and more pronouncedly vertical ; sculp- 

 ture of propodeum somewhat stronger than in female ; abdomen with 

 a large basal whitish spot. 



Habitat. — Department of Piura, Peru, 



Host. — AntTionomus vestitus. 



Type.— Cat. No. 14613, U.S.N.M. 



The type female reared from the above host and sent by Prof. C. H. T. 

 Townsend under his number 795° 3e; the male reared from cotton 

 squares. Several paratypes reared from the host and others \nth the 

 record that they issued from cotton squares. 



This species is easily distinguished from C. Tiunteri by the sculpture 

 of the face, the postvertex, the lateral lobes of the mesoscutum and 

 of the propodeum. 



Family EULOPHID^. 



A thorough revision of the genera of this subfamily from the stand- 

 point of the genotypes is greatly needed. The confusion in which the 

 genera still exist may be well illustrated by referring to the species 

 assigned below to the genus Pleurotropis. These are strictly conge- 

 neric, but were described in various genera and for the most part 

 left in the genera in which they were originally described. A notable 

 exception to this is the species (Asecodes) Pleurotropis alhitarsis Ash- 

 mead, which Doctor Ashmead had placed in the collections in the 

 genera Asecodes, Entedon, Mestocharis, and Pleurotropis. 



Until such a revision is made species must be arbitrarily assigned 

 to the genera to which they appear to belong or new genera described 

 for them. Since the latter procedure seems unnecessary the former 

 is here adopted in the assignment of the species placed in Derostenus 

 (in this case for additional reasons discussed under the remarks on 

 that genus) and in Chrysocharis . 



CHRYSOCHARIS PARKSI, new species. 



Female. — Length about L25 mm. Green with brassy tints, the 

 lower part of the face bronzy; face below transverse furrow reticu- 

 lated; area surrounding ocelli very faintly reticulated ; vertex sharply 

 carinate; scape in front, except apex, whitish; funicle three-jointed.
