(ADIOSTOLA [sic!] TESTACEIPES Ashmead MS.)=LYMEON? TESTACEIPES Cushman, 

 new species. 



♦ALEXETER ALBOTARSATUS (Provanchcr). 



Paniscvs albotarsatus Pkovanchei:, Nat. Can., vol. 6, 1874, p. 106, male 

 and female; Nat. Can., vol. 11, 1879, p. 146, male and female; Faune 

 Ent. Can. Hym., 1883, p. 361, male and female, and p. 785, female. 



The type of this species has been examined by Mr. A. B. Gahan, 

 and a specimen compared by him with the type is in the National 

 Museum collection. This is an Alexeter. Mr. Gahan was of the 

 opinion that two of the three females assigned to this species by 

 Provancher were not the same species as the type male, while the 

 other might be. Provancher's statement that the ovipositor is 

 longer than the thicloiess of the abdomen would seem to indicate 

 that the female described is not an Alexeter. As to what these 

 females are Mr. Gahan makes no statement in his notes. 



This species is not known from Mount Washington, but is dis- 

 cussed here because it is involved in the confusion in relation to 

 Parabatus monticola Cushman, new species, described on a later 

 page of this paper. 



ALEXETER RIPARIUS (Davis).

At my request Mr. S. A. Rohwer has, during a recent visit to 

 Philadelphia, compared the type of Ashmead's manuscript name with 

 tliat of riparius Davis and pronounces them the same. 



If the right wing of the type of Ashmead's name is used in run- 

 ning it through Davis's key to the Mesoleptini it will run to Alex- 

 eter^ but it is none of the species placed there by Davis. The left 

 w^ing, having the areolet incomplete, runs it to Mesoleptus, where 

 Davis placed his species. Ashmead's type differs from that of 

 riparius by having the mesopleurum very largely and the propodeum 

 and metapleurum entirely black. Two males from Georgetown, 

 District of Columbia, and Rosslyn, Virginia, lack the areolet and 

 conform more closely in color to the description, though one has 

 the hind femora red instead of black. 



The distinct glymmae place the species in Alexeter. 



(AMEROLYTUS [sic!] FLAVIFRONS Ashmead MS.)=EXOCHUS ALPINUS Cushman, new- 

 species. 



APERILETUS CLYPEATUS, new species. 



"Aperileptus clypeatiis Ashm., n. sp.," Si.osson, Ent. News, vol. 13, 1902, 

 p. 6. 



No specimens from Mount Washington have been found, but one 

 so labeled by Ashmead from Franconia, New Ham.pshire, is the basis 

 of the following description.
