In addition to descriptions of twelve species believed to be new 

 to science and falling in the Hymenopterous superfamilies Ichneii- 

 monoidea, Chalcidoidea, and Serphoidea, this paper contains notes 

 on several described species. All of the new species are described 

 from reared specimens, and more or less definite host records are 

 given for each species. Included are notes on three species from 

 India, one from South Africa, one from the Panama Canal Zone, one 

 from Porto Rico, and several from the United States and Canada. 



Superfamily ICHNEUMONOIDEA. 

 Family BRACONIDAE. 



ROGAS HYPHANTRIAE, new species. 



In general appearance very closely resembles terniinalis Cresson 

 but is at once distinguished by having the abdomen practically de- 

 void of distinct striae, whole third tergite opaquely sculptured, fourth 

 also opaque for the most part, first abscissa of discoidal vein hardly 

 longer than nervulus, ocelli distant from the eye-margin distinctly 

 more than the greatest diameter of an ocellus, and mesosternum en- 

 tirely, mesopleura below, and the metapleura finely coriaceous and 

 opaque. Also resembles harrimani Ashmead but may be distin- 

 guished by the same characters which separate it from terminalis. 



Female. — Length 6.5 mm. Head finely granularly punctate, the 

 face with a few indistinct transverse rugae; malar space approxi- 

 mately equal to length of scape, malar groove absent; eyes weakly 

 emarginate within; ocelli not large, antennae inserted above the 

 middle of the face, 46-jointed, the third joint about twice as long as 

 thick, all joints of flagellum longer than thick; mesoscutum sculp-
