ART. 23. NEW SPECIES OF ICHNEUMON-FLIES CUSHMAN. 11 



verse; ovipositor slender, longer than abdomen, apex subsagittate 

 with two notches dorsally. 



-Black with abdomen beyond first tergite and legs largely reddish ; 

 clypeus, mouth parts, tegulae, humeral spot, subtegular spot, and 

 anterior coxae in front white; a very small spot at top of eye and 

 one on side oi" mesoscutum brown; antennae black with basal joints 

 brown, especially beneath ; hind tibiae at apex and their tarsi slightly 

 infuscate; wings hyaline, venation brown; first tergite at apex red- 

 dish, second with a median blackish spot ; ovipositor sheath black. 



Male. — Differs from female in being more slender and in color as 

 follows : Spot at top of eye together with small spot on lower inner 

 orbit and paired spots on middle of face yellow ; coxae black at base, 

 hind pair largely so, otherwise, together with front trochanters, 

 white; abdomen largely black, the red being confined to the lateral 

 margins and sutures. 



Host. — Pith-borer in pear twigs. 



Type locality. — China. 



Type.—C2it. No. 24619, U.S.N.M. 



Described from seven specimens in two series. The series from 

 which the type is selected consists of two females and one male 

 reared at quarantine, Washington, District of Columbia, under 

 Federal Horticultural Board No. 29265, from material received from 

 China. Four other females were reared from galls on pear col- 

 lected by F. N. Meyer in the Pangshan Mountains, North China. 

 These are somewhat larger, more coarsely sculptured, and with the 

 red of abdomen and legs paler than in the others. The hind tibiae 

 and tarsi are entirely red. The brown spot on mesoscutum is larger 

 than in the type. The male and the second female of the first series 

 lack the mesoscutal spots entirely. 



Subfamily Tryphoninae. 



(SYCHNOLETER) ZAGRYPHUS AMERICANUS (Ashmead). 



Ashmead's type (Cat. No. 22748, U.S.N.M.) is a male. Both hind 

 tarsi, all but two joints of the left antenna, and all but six joints of 

 the right antenna are missing. It is of about the same length as 

 namtus (Cresson), but more slender with the head smaller. It may 

 be further distinguished from the male nasutus as follows : 



Head black; clypeus nearly twice as long as face; propodeum strongly mu- 

 cronate on each side behind ; postpetiole as wide at apex as long from 

 spiracles; second tergite as wide at apex as long, its sides divergent. 



nasutus. 



Head brown; clypeus only slightly longer than face; propodeum weakly mucro- 

 nate; postpetiole narrower at apex than long from spiracles; second ter- 

 gite narrower than long and parallel-sided americanus.
