short, and seen from behind both they and their tarsi are of a uniform

 than mfoxii or universitatis . The face is covered with white hair, and 

 the flagellum is dull ferruginous beneath. The tegulse are as mfoxii.

DOUBTFUL AND EXCLUDED SPECIES. 



Andrena valida Say . Viereck (in litt.) has suggested that this may 

 be a Nomia. If so, it must be closely similar to .V. hfteropoda, bcinn 

 a large species with purplish-fuliginous wings. 



Nomia hi i-l: inn n'i FrieseMS., Entom. Xews, 1899, p. 244, from Texas, 

 has not been described. 



N. compacta Provancher, 1888, from Cap Rouge, Canada, is based 

 on a male, and from the locality and description 1 suspect that it may 

 not be a Ntfmia. The following characters seem significant : ' ' La face 

 allong6e, presque Que, le chaperon noir fonce, fortement tronque" en 

 avant et le^erement reflechi, brillant . . . pattes noires, bril- 

 lantes, les euisses et les jambes renflees, arquees, avec poils blan.es 

 peu denses, les tarses testaces-roussatres . . le septieme [segmenl 

 of abdomen] portant tin petit appendice noir en forme de gouttiSre." 



Paranomia venablesii Ashmead belongs to Halictus (H. farinosus 

 Smith). 



Nomia tacita Cameron is Agapostemon sicheli Vachal. 



Nomia cillaba Cameron is also an Agapostemon. 



Nomia cselestina Westwood is an Agapostemon.
