56 HYMENOPTERA. 



Genus WESTWOODELLA Ashmead. 

 1. Westwoodella americana (Ashmead) Girault. 



Oligosita americana Ashmead — Girault, 1909, pp. 106-110. 



This species was described recently ; it is removed to this 

 genus because of the substigmal fumated spot which it bears 

 on the fore wing. 



In addition to what has already been written concerning 

 it, in the original description, I desire to place on record the 

 fact of having seen the original slides bearing the specimens 

 from which Ashmead named the species and to add one or 

 two important notes. The original specimens were found 

 in a collection of slides kindly loaned to me for study by Dr. 

 L. O. Howard. Amongst this collection I found four slides 

 labelled in Ashmead 's handwriting " Oligosita americana 

 Ashm." and bearing two distinct species of this genus, W. 

 americana and W. sangzdnea nova, described beyond. The 

 labels of these slides were in detail as follows, merely the 

 scientific names of the parasites being in Ashmead's hand- 

 writing : (1). "W. No. 1892'' F. M. Webster, Wooster, 

 Ohio ; Urbana, Illinois. Reared with E. eragrostidis. Oli- 

 gosita americana Ashm. Polyriema ci tripes Ashm." This 

 slide bears 2 cf's, 2 9 's of Westivoodella sanguinea Girault 

 and 1 cJ", 1 9 of Polynema longipes (Ashmead) Girault. (2). 

 "Webster No. 1892. Olizosita americana Ashm. 9 ." This 

 slide bears three female specimens of W. safigiiinea. (3) 

 " Webster No. 1892. Oligosita americana Ashm. 9 ." This 

 slide bears single male and female specimens of W. san- 

 guinea Girault. And (4). "Webster No. 1895''. Oligosita 

 americana Ashm. 9 ." These specimens were 6 males and 3 

 females of W. americana, hence forming all of the original 

 specimens. 



In the original description of this species it was stated that 

 the description was based on five female specimens but a re- 

 examination of the slide bearing the type specimens shows 

 that this was a mistake, there being in reality but a single 

 female specimen present the other four being males. From 

 this single female specimen and the three additional ones 

 forementioned, it is seen that the males differ from the
