 Ashmead cites no typo, but l>as kindly sent us the type 

 species, an undescribed form troin Sm Fraiu-isco Co., Calif., 

 collected in October. It is superlicially ju.st like Antliophora 

 Porterd', Ckll., but differs in venation and other particulars, 

 and is certainly not congiMieric. In Cres.son's tables it runs 

 to llabropodn. but Cresson's '" ILi'iropoda " is ICmphoropsis, 

 The second .subinarginal cell along the cubitus is shorter than 

 the first or third, whereas in E. salviarum and fioridanus it is 

 about eijual to the third. The male Melitargopsis has the 

 scape all black, clypous white except sides and anterior edgo, 

 lateral face-marks V-.sliaped ; hair of thorax greyish white 

 mixed with black ; abdomen without bands, tirst segment 

 densely covered with greyish-wliite hair. 



Mcliturgopsis seems practically identical with Emphoropsis^ 

 tlie latter having priority of place.

This genus is omitted Ijy Ashmead. It differs from other 

 genera of Anthophorinai by its 3-jointed maxillary palpi ; 

 the tongue is as long as the body ; antenna? filiform, as long 

 as the thorax.
