Female. — Length, G.5 mm.; antennae, 4.5 mm.; ovipositor, 1 mm. 



Very similar in structure and sculpture to yukmiensls^ except that 

 the malar space and temples are slightly shorter, and the first tergite 

 is only about two-thirds as wide at apex as long, only weakly arched, 

 and without dorsal carinae. 



Inner orbits, cheeks, clypeus, and scape and pedicel below reddish ; 

 flagellar annulus embracing the sixth and portions of the fifth and 

 seventh joints; palpi, propleura, beneath, lower and upper hind mar- 

 gins of pronotum, wing-base, tegula, a line below, front and middle 

 coaxe and trochanters, and the extreme apices of all tergites and 

 sternites white ; mesothorax above and below largely rufous, notauli 

 black, running into a triangular brownish spot posteriorly, scutel- 

 lum rufous, space around bases of wings blackish ; metapleura bright 

 reddish piceous, the sterum rufous; body otherwise black to piceous; 

 legs, except as noted, pale testaceous, the front and middle pairs 

 paler, their tibiae whitish above. 



Host. — Phloeosinus^ species. 



Type-locality. — Cypress Point, Monterey, California. 



Type.— Cat No. 21635, U.S.N.M. 



Described from one female bearing the label " Parasite from gal- 

 lery of Phloeosinus sp. on Ciipressus inacrocarpa^ 1903, Hopk. det. 

 No. 18." 



CRYPTOHELCOSTIZUS, new genus. 



Related to Helcostizus (Foerster) Dalla Torre and Gryptoideus 

 Ashmead, from which it is readily distinguished by the characters 

 used in the key. 



Runs in Schmiedeknecht's key (Genera Insectorum) on the pos- 

 session of a clypeal tooth to Xylophrurus Foerster, but differs in 

 having the head strongly transverse with the temples short and nar- 

 row; in lacking the dark alar bands; in the rather small clypeal 

 tooth ; in the nongibbous mandibles ; in the oval propodeal spiracles ; 

 in the weak petiolar carinae; in having the spiracles of the first 

 tergite in or slightly before the middle. 



Type. — Cryptolielcostizus 7^-figaster^ new species, described below. 



CRYPTOHELCOSTIZUS RUFIGASTER, new species. 



Female. — Length, 11 mm.; antennae, 8 mm.; ovipositor, 3 mm. 

 Head in front densely rugoso-punctate, the sculpture fading out be- 

 hind the eyes, temples and cheeks polished, impunctate ; clypeus very 

 short, subimpressed beyond middle, broadly, subemarginately trun- 

 cate, the edge granular with a slight median tooth; malar space 

 slightly more than half as long as basal width of mandible; cheeks 

 slightly convex, temples flat, sharply sloping, their cephalo-caudad 

 leng:th less than a third that of the eye; thorax generally rugoso-
