Report upon Aculeate Hymenoptera. 239 



St. Vincent — Kingstown ; Grenada — Windward side. 

 Four ^ and seven ^ specimens. A ^ and a $ labelled 

 St. Vincent (Windward side) were taken in coitv. 



The species is quite distinct from niediata, and is in no 

 sense a variety of it as some authorities have indicated. 



Genus Pseudomethoca, Ashmead.

 but laterally separated by a black stripe ; abdominal segments with 

 a small wedge-shaped sj)ot at apex. Antennae and mandibles rufo- 

 piceous. Legs dark rufo-piceous, almost black, the tarsi testaceous. 

 Head large, quadrate, the temples broad, acute behind and ending

St. Vincent. Described from one $ and one (^ specimen. 

 The female is labelled " Golden Grove (Leeward), 800 feet, 

 Dec. 7. Found dead in a jar of water from aneigiibonring 

 spring." The male is labelled " Sea level, Windward side." 



Mr. Wm. J. Fox, in " The American ^fiUiUirLv," p. 221, 

 says : " The groups represented by Pscudomctlioca, Ash- 

 mead, are the American representatives of Myrmilla 

 (Wesm.), Andre." In this Mr. Fox is quite mistaken, and 

 he probably wrote the sentence before my generic table of 

 the Mutillidm appeared. The only representative of Myr- 

 milla, Wesmael, in America, that I have seen, is Mutilla 

 grandiccps, Blake, which represents (juite a distinct group 

 from Pseud omethoca.
