NO. 2249. ICHNEUMON-FLIES FROM JAVA—ROHWER. 569 



brownish ; along the anterior margin of first abscissa of cubitus and 

 basal margin of second discoidal clear hyaline ; venation the color of 

 wing; stigma yellow basally, black apically. 



Cocoon. — 9.5 mm. by 4.5 mm. by 1 mm. Thin brownish, papery; 

 single walled ; parallel-sided with the ends rounded ; flat, of uniform 

 thickness throughout. 



Type-locality. — Cheribon, Java. 



Described from one male reared from a cocoon collected under 

 bark and believed to be parasitic on Chrysohothefis sexnotatus. 

 Reared by K. W. Dammerman under his number 396.

ONCOPHANES HESPERIDIS. new species. 



In Szepligeti's key^ this space runs to the genus Clinocentrus 

 Haliday. In Ashmead's key ^ it agrees better with Oncophanes, but 

 even here the venation is somewhat at variance with the characters 

 given. In habitus and abdominal structure it is more like Onco- 

 fhanes^ and it seems to congeneric with 0. launceolator Nees, even 

 though the venation is different. 



Female. — Length, 2.75 mm.; length of ovipositor, .75 mm. Head 

 shining, polished, distinctly narrowing behind the eyes; eyes large, 

 subreniform, and slightly converging below; antennae with more 

 than 30 joints; ocelli in nearly an equilateral triangle; thorax shin- 

 ing; prescutum with a median depression; suture in front of the 

 scutellum with a few poorly defined rugae; propodeum with a me- 

 dian longitudinal carina, which becomes forked posteriorly; the 

 area along this carina and the posterior face irregularly reticulate; 

 first tergite short, the posterior width as great as the length, sharply 

 margined laterally, its surface rather uniformly finely striate, with 

 two carinae near the middle more prominent; second tergite fully 

 one and two-thirds times as wide as long, shining without sculpture ; 

 the following tergites without sculpture, soft; ovipositor not half 

 as long as abdomen; nervulus postf ureal by nearly its length; re- 

 current received in first cubital well before the intercubitus ; first 

 abscissa of radius two-thirds the length of first intercubitus; second 

 abscissa of radius fully one and one-half times as long as the first in- 

 tercubitus. Uniformly reddish-yellow ; interocellar area and sheaths, 

 brown, wings hyaline ; venation pale brown. 



In one paratype the tergites are brownish. 



Type-locality. — Buitenzorg, Java. 



Described from three females reared from a Hesperid larva, Feb- 

 ruary, 1916, by K. W. Dammerman.
