63 1 NEW SPECIES OF BRACONID.E. 



Described from one specimen, labeled Hold era ess, N. H., September', 

 1883. This .species agrees somewhat with Bh. fulvm, but the eyes are 

 emarginated directly opposite the base of the antennae. 



Rhogas nolophanae n. sp. 



Female. — Length, a to 5f""". This species in color and structure is 

 also like /.'/(. platypterygis. The antennae are 39 jointed, concolorous with 

 the body, the flagellar joints being slightly more than twice longer than 

 wide; the venation as in Bh. simillimus, only the stigma and veins are 

 yellowish ; the stigma is slightly dusky apically. 



Habitat. — Missouri. 



Described from three specimens, all females, labeled No. 41 xo , and 

 reared November 3, 1871, from Nolophana malaria Fitch. (Coll. C. V. 

 Riley.) 



Rhogas cerurae n. sp. 



Female. — Length, 3f mm [male 3 mm ]. This is still another species that 

 could be confused with Bh. platypterygis, agreeing with it in color and 

 sculpture; it is, however, slightly smaller; the parapsidal grooves sharply 

 defined, complete ; the antennae in female 32-jointed, in male 31-jointed, 

 the flagellar joints being about twice as long as wide; the venation of 

 the wings is exactly as in Bh. platypterygis. 



Habitat. — California. 



Described from four specimens, three females, one male, reared by 

 Mr. Albert Koebele, in Napa County, California, from Cerura sp. found 

 on willow, in August, 1887. 



Subfamily CHELONINiE. 

 TETRASPH.EROPYX n . g. 



The whole insect is very hairy; antenna? very long, multiarticulate- 

 thorax without distinct parapsidal grooves; metathorax short, round- 

 edly truncate posteriorly, medially keeled; the abdomen is divided into 

 four distinct segments, the sutures strongly constricted, the basal two 

 segments having a delicate, central, longitudinal carina; while the 2d 

 submarginal cell is quadrate not as long as the 1st branch of the radius. 



This genus is very close to Sphivropyx Haliday and PJianerotoma 

 Wesmael, but 'can at once be separated from them by the number of 

 abdominal segments and the quadrate 2d submarginal cell. 



Tetrasphaeropyx pilosus Cr. 



Rhogas pilosus Cross., Trau. Am. Ent. Soc, IV. p. 189. 



Habitat. — Texas. 



Three specimens of this rare insect, in the Belfrage collection now 

 the property of the U. S. National Museum, convince me that Mr. Cres- 

 son was wrong in placirg this Braconid in the group Bhogadiiwe, that ifc 

 belongs with the Cryptogasters in the above group, and is the type of 

 a new genus.
