ART. 8 NOTES ON PARASITIC HYMENOPTEEA GAHAN 9 



SO strongly sculptured as mesoscutum, the lateral grooves punctate; 

 axillae finely reticulated; propodeum with the usual longitudinal 

 depressed area on each side of the middle, these areas granularly 

 rugulose and completely separated by a smooth median area which 

 is of about the same width as one of the depressions; base of pro- 

 podeum on either side of the middle with a transverse depressed area 

 or large fovea which is faintly rugulose within; spiracular groove 

 rugulose; rest of the propodeum smooth and polished except that 

 the apical neck is more or less granularly sculptured laterally; pos- 

 terior lateral angle of propodeum forming a short spinelike projec- 

 tion ; abdomen shorter than the thorax, truncate at apex, the segments 

 beyond the second almost wholly retracted into the second; petiole 

 a little longer than broad and rugulose ; second tergite large, polished 

 basally, with the apical two-thirds very finely shagreened ; marginal 

 vein of f orewing much longer than submarginal , the latter with two 

 erect spines dorsally. Scape, except at apex, and legs, except their 

 coxae, pallid; occiput and declivous anterior portion of pronotum 

 blackish ; remainder of head, pronotum posteriorly, mesoscutum and 

 scutellum, axillae, and smooth portion of propodeum greenish black, 

 with a strong aeneous cast; remainder of propodeum, metanotum, 

 pleura, and coxae black or bluish black; abdomen black, faintly 

 tinged with aeneous; wings hyaline; antennae, except basal three- 

 fourths of scape, black, tinged with aeneous. 



Male. — Length, 1.8 mm. Antennal funicle distinctly 4-jointed; 

 first and second funicle joints subequal and each about twice as long 

 as thick, third joint slightly shorter, fourth about as broad as long ; 

 club not twice as long as fourth funicle; segments of abdomen be- 

 yond the second wholly retracted ; head above and mesonotum some- 

 what more strongly aeneous than in the female. Otherwise like the 

 female and hard to distinguish from it except by the antennae and 

 genitalia. 



Type locality. — Alhambra, Calif. 



Type.— C?it. No. 41101, U.S.N.M. 



Described from 3 females and 15 males reared from Bruchus 

 pruininus Horn by C. K. Fisher. 



PLEUROTROPIS DETRIMENTOSUS, new species 



Very similar to nawaii Ashmead but differs by having the fronto- 

 vertex much smoother and the scutellum with a broader, well-defined, 

 polished area down the middle. 



Female. — Length, 1.6 mm. Head slightly broader than thorax; 

 ocellar triangle distinctly rugulose; vertex laterad of lateral ocelli 

 smooth; fronto-vertex with very faint reticulate sculpture, nearly 

 smooth; frons on each side of antennal groove and below the trans-
