Sept., 19II.] Girault: Notes on Hymenoptera Chalcidoidea. 185 



(Abbella) Trichogramma acuminatum (Ashmead), which I have described in 

 full elsewhere (Trans. Amer. Ent. Soc, Phila., XXXVII, 1911, pp. 13, 77-82). 



Of BrachistcUa acuminata (Ashmead), very recently I have cap- 

 tured the following specimens : A female at Coulterville, 111., June 20, 

 191 1, on the window of a wagon repair shop in company with Aphc- 

 linoidea semifuscipennis; three females in the same locality, same 

 time, on the window of a foundry adjoining; a female at Urbana, 

 111., May 17, 191 1, on the window of a small granary (stored corn) ; 

 another female, same locality, May 21, 191 1, on the pane of a window 

 in a livery stable; nine females at St. Joseph, 111., May 21, 1911, on 

 the windows of a livery stable; and on May 31, 1911, two females 

 together on a window in a hennery on a farm at Hendrix (Bloom- 

 ington), 111. The species appears, then, to be very common in the 

 state of Illinois. 



Genus APHELINOIDEA Girault. 

 Aphelinoidea semifuscipennis Girault. 



On June 10, 191 1, several female specimens of this species were 

 captured from the panes of a window in the loft of a livery stable at 

 Nashville, 111. They serve to confirm the original description of 

 the species and the locality is new. They were running slowly over 

 the pane and resembled to the eye, dark specimens of Pentarthron 

 minutum (Riley) ; also four females, two each on the windows of a 

 wagon repair shop and foundry respectively, at Coulterville, 111., 

 June 20, 191 1 ; and one June 15, 191 1, Marissa, 111., on a window in a 

 hennery. 



Genus WESTWOODELLA Ashmead. 

 Westwoodella sanguinea Girault. 



This interesting species has been collected recently in the follow- 

 ing localities: One female, Coulterville, 111., June 20, 191 1, on the 

 window of a foundry in company with the Aphelinoidea and Brachi- 

 sfella. A female at St. Joseph, 111., May 21, 191 1, on the window of 

 a livery stable and three females at Hendrix (Bloomington), 111., 

 May 31, 191 1, on the window of a barn on a farm. All the foregoing 

 are the typical red form.
