and then running parallel to each other for a short distance. Antennae 

 inserted slightly higher up on the face yet still considerably below the 

 level of the eyes ; scape shorter and not quite so wide ; pedicel no longer 

 than thick and about one-half as long as the first funicle joint ; funicle 

 slender, the joints decreasing slightly in length distad, the basal joints 

 twice as long as thick; club solid, slender, as long as the last two joints 

 of funicle combined ; the funicle and club to a less extent clothed with 

 long, erect and numerous hairs above, and with considerably shorter, 

 nearly decumbent hairs beneath. Sculpture about the same, except that 

 the frontovertex is more coarsely or rugosely reticulate with scattered 

 pin-punctures. Coloration the same with the metallic luster weaker. 



Genotype: Cerchysius ivhittieri Girault, ^vliicli ^virhout 

 doiiLt is Ashmead's manuscript species, Ilemenci/rtus ciuirii. 



This genus, which is dedicated to Prof. H. J. Quayle, who 

 lirst made known the life-history of the type species, is most 

 closely related to the Hemencyrtus Ashmead and mnoh les.s 

 closely I believe to Cerchysius Westwood. 



The species belonging here are secondary parasites of Cocei- 

 dae and parasitize the larvae of various other chalcid-flies j>uch 

 as Scutellista, Tomocera and Microterys. They pupate within 

 the larval skin of their host which they transform into a brown 

 puparium-like shell. 



Quaylea aliena n. sp. 



Female: Very clos^- structurally to Q. zvliittieri (Girault), on which 

 the generic description is solely based, and differs only as follows : the 

 frontovertex a trifle wider with the orbital row of pin-punctures less 

 distinct; the pedicel twice as long as the first funicle joint, which is not 

 over one-half as long as the second and about as long as wide, the fol- 

 lowing four funicle joints subequal in length and increasing slightly in 

 width distad, each a trifle longer than wide, the sixth as wide as long 

 and a trifle shorter than the preceding joint; the double, marginal 

 fringe of hairs on the last tergite very much shorter and inconspicuous. 



Length excluding ovipositor : .gi to 1.96 mm. 



Coloration as in whittieri except that the mesonotum has a bluish and 

 purplish luster instead of greenish ; the frontovertex slightly more bluish, 

 and the luster throughout more brilliant. Head deep blue-black, the 

 frontovertex with a blue-green luster; notum of thorax bluish black, the 

 scutellum and metapleura aeneous black with a strong green or bronzy 

 green luster, the smooth sides and apex of scutellum and the metapleura 

 refulgent, the underparts of thorax otherwise shining black; abdomen 

 black, the dorsum and especially the basal tergite with a strong blue and
