NO. 2195. NEW SPECIES OF HYMENOPTERA—ROUWER. 163 



Family BRACONIDAE. 



COSMOPHORUS PITYOPHTHORI, new Bpecies. 



This species is closely allied to but may be readily separated from 

 hopkinsi Ashmead by the sculpturing of the first tergite, the darker 

 and shorter first abscissa of radius. 



Female. — Length 2.5 mm ; length of ovipositor .75 mm. Head shin- 

 ing; antennae slender, 14- jointed, the third and fourth joints sub- 

 equal; mesoscutum shining; propodeum granular with the faint ca- 

 rina separating the dorsal and posterior aspects; discocubitus joining 

 the radius so near base that there is no real first abscissa of radius; 

 first tergite striato-granular; remaining tergites shining impunctate. 

 Black; legs and abdomen beyond first segment dark piceous; wings 

 hyaline, faintly dusky, venation pale brown. 



Male. — Length 1.75 mm. Differs from the female in having a few 

 striae at the base of the second tergite; and in the 13-jointed anten- 

 nae. 



Type-locality. — Moraga Ridge, Oakland, California. Described 

 /rom three females (one type) and one male (allotype) reared fnmi 

 twigs of Pinus tuberculata infested by Pityophthorus., species. Ma- 

 terial collected by F. P. Keen. 



Type.— C^t. No. 19951, U.S.N.M. 



Genus DIOSPILUS Haliday. 



As used here the genus Diospilus agrees with the characterization 

 given by Szepligetti. How^ever, the last two species described are 

 not typical in venation and might be the types of a new group, but 

 it seems to the author that the characters offered for the genera of 

 this subfamily are not such that they may be expected to hold for a 

 large number of species. He has therefore considered it advisable to 

 place calif ornicus and neoclyti in the genus Diospilus. 



A. CLYPEUS NOT SHARPLY DEFINED LATERALLY; WIDTH FTTLLY THREE 

 TIMES AS GREAT AS THE MEDIAN LENGTH; FIRST ABSCISSA ON 

 THE RADIUS LESS THAN ONE-FIFTH THE LENGTH OF THE SECOND. 



DIOSPILUS WASHINGTONENSIS. new species. 



Feviale. — Length 6 mm.; length of the ovipositor 7 mm.; length 

 of the antennae 4 mm. Clypeus shining, with large separate punc- 

 tures; head immediately below the antennae transversely striato- 

 punctate, rest of the head below the antennae with sparse, well sepa- 

 rated punctures; head above the antennae and posterior orbits shin- 

 ing, impunctate; ocelli in an equilateral triangle; third antennal 

 joint slightly longer than the fourth; prescutum, scutellum, and
