P. (Catolaccus) anthonomi Ashmead. Insect Life, Vol. v,

Female : length 2.8 mm. ; mostly blue ; head and thorax faintly 

 tinged with metallic green; flagel brown, scape honey-yellow; 

 head confluently punctate, front impressed, clypeus sinuate at 

 the middle; antennae 13-jointed, inserted on the middle of the 

 face, scape about one-half as long as the flagel, pedicel smaller 

 than the first joint of the flagel, joints of the flagel almost 

 equal in length and thickness; thorax ovoid, confluently 

 punctate, prothorax rounded, parapsidal grooves present only 

 anteriorly, metathorax two-thirds the length of the scutel, 

 its spiracles close to the postscutellar fold and elliptic-oval, lateral 

 folds complete, and a slight median carina at base ; wings hya- 

 line, veins pale yellowish, stigmal vein two-thirds as long as the 

 postmarginal ; trochanters, tips of femora, tibiae and tarsi honey- 

 yellow, coxae and femora mostly bluish, hind coxae punctate, the 

 inner ridge with pubescence ; abdomen conic-ovate, about as long 

 as the rest of the body combined, subsessile, first, fifth, sixth, and 

 seventh dorsal segments about equal in length and together about 

 as long as the second, third, and fourth combined, second and 

 third together only slightly longer than the fourth. Male: length 

 2 mm.; golden green; scape and legs, except hind coxae and 

 femora, yellow, tips of hind femora also yellow ; flagel pale brown, 

 pubescent, pedicel smooth and dusky, joints at end of funicle 

 slightly longer than thick, the joints at its base one and a half 

 times as long as thick ; abdomen oblong-oval, first and fifth seg-

 to the club, the apical joint a little wider at base than at apex, 

 at least the first and second joints of the club wider than long; 

 head wider than the thorax, about three and one-half times as 

 wide as thick antero-posteriorly, thinnest at the middle; meta-
