NO. 2261. NEW REARED PARASITIC HYMENOPTERA—OAHAN. 121 



sparse rather distinct punctures; second tergite fully four times as 

 broad as long down the middle and sculptured like the first but 

 more weakly; following tergites smooth; hypopj'gium not reaching 

 to the apex of abdomen; ovipositor sheaths three- fourths as long 

 as the abdomen, strongly compressed, blade-like, one-sixth as broad 

 as long or nearly, and fully as broad as the greatest width of the 

 hind femora; ovipositor slender, cylindrical, and slightly curved 

 downward at the tip. 



Male. — Antennae much longer than the body, all flagellar joints 

 being at least nearly three times as long as thick ; propodeum at the 

 apical middle with distinct aciculations ; second tergite a little more 

 than twice as broad at apex as long down the middle ; otherwise the 

 male is like the female except smaller, being but 2.4 mm. in length. 



Type-locality. — Williamsport, Maryland. 



Type.— Cat. No. 21619, U.S.N.M. 



Host. — Stagmatophora gleditschiaeella Chambers. 



Type, allotype, and male paratype reared by W. R. McConnell 

 under cage No. 664 ; also two female paratypes from the same locality, 

 one of which was collected by P. E. Myers and bears No, 692, the 

 other by .W. E. McConnell and bearing No. 689. 



Mr. McConnell's specimens were reared from cocoons found in bur- 

 rows of the host larvae, and these burrows were fully made, with no 

 signs of any pupal host, w-hich is pretty good evidence that they 

 emerged from the mature host larva. 



APANTELES EMPRETIAE Viereck. 



Apanteles (Protapanteles) e7n pretiae Yierkck, Proc. U.S.Nat. Mus., vol. 44, 



1913, p. 562. 



Apanteles (Apanteles) sibinidis Rohwer, Proc. U. S. Nat. Mus., vol. 49, 



1915, p. 227. 



Types of enipretiae Viereck and sibinidis Rohwer have been com- 

 pared and are undoubtedly the same species. Both were originally 

 recorded from the same host, {Empretia) Sihine stimulea Clemens, 

 and both are from the neighborhood of Washington, District of 

 Columbia. 



APANTELES FUMIFERANAE Viereck. 



Apanteles (Apanteles) polychrosidis Viereck, Ptoc. U. S. Nat. Mus., vol. 42, 

 1912, p. 615. 



Types of these two species have been compared and the writer is 

 of the opinion that they are synonymous. 



Subfamily Blacinae. 



ORGILUS DIORYCTRIAE, new species. 



Female. — Length, 4.6 mm. Deep shining black; basal joints of 

 the flagellum, the mandibles, apex of the median and anterior femora
