fixation have required a new group name. For this group 

 Gahan has proposed the name Vipiinae*"". This name appar- 

 ently cannot stand. In the tirst place the genitive oiy'ipio 

 is Vipionis, and the subfamily name bivsed on it is correctly 

 Vipioninae which the writer used in the place referred to. 

 But the name of the genus which is the type of the subfam- 

 ily is now ]\[icrohracon and the subfamily should then be 

 called the Microbraconinae. 



The Braconidae tabulated here have been placed in 

 various subfamilies but to the writer they seem to belong to- 

 gether. However, in default of opportunity for thorough 

 consideration of the matter he does not wdsh to give them at 

 present any common designation. 



They have the following characters in common: the head 

 is completely margined behind and there is a sinus between 

 the clypeus and the mandibles. In all but the wingless 

 endemic E cpliylofsis nigra Ashmead the parapsidal furrows 

 are strongly impressed, there are two closed cubital cells in 

 the front wing and in the hind wing there are two cross 

 veins extending backward from the mediellan A^ein, a nervel- 

 lus near the middle of the mediellan cell and a postnervellus 

 interstitial with the basellus. All the species so far as their 

 habits are known are parasites of beetle larvae and all of these 

 but Heterospilus prosopidis. the Briichus parasite, attack 

 wood-boring beetles. The habits of the endemic Erphylopsifi 

 are unknown.
