A PARTIAL LIST OF NEW SPECIES OF PARASITIC II YMKNOl'TEU A REARED IN 



Indiana. By F. M. Webster. 

 In the fallowing list it is my intention to include only such species as 

 were undescribed at the time they were reared by myself during an eight 

 years residence in the State. These have nearly all been since described 

 and, with but few exceptions, from types furnished by my rearings. The 

 object in presenting this matter is to place it in a form convenient for 

 reference by the future investigator, reference in all cases being- given to 

 the original description. I have not as yet been able to complete the list 

 of those now described, and still others remain to be described, but I 

 hope to include all or nearly all of them in a future paper: 



1. Bracon agrili Ashm. From larvae of Agri'us fulgens Lee, burrowing 

 in trunks of maple. La Fayette, April and May. (Proc. U. S. Nat. Mus., 

 1888, p. 612.)

 has reared R. lineaticollis from Asclepius in Massachusetts, and that it is 

 there attacked by a Hymenopterous parasite.
