Exomalopsis mellipes, Cresson. 



The male, not before known, has been collected by IT. II. 

 Hyde at Medellin, Vera Cruz, Mexico (Baker coll., 17H5). 

 It runs in Friese's table of males to E. planiceps, Sm., but 

 is larger, with red legs. 



Exomalopsis vincentana, Cockerell. 



The male, previously unknown, was collected by II. II. 

 Smith on the windward side of St. Vincent. It is hardly 

 5 mm. long, and there is much black hair on mesothorax, 

 scutellum, and legs. It is nearest to E. globosa, but dis- 

 tinguished at once by the ochreous-yellow tarsi. 



There is a series of small Exomalopsis (including Antko- 

 phorula), which are superficially similar and easily confused. 

 They may be separated by the following table, based ou 

 females : — 



Second abdominal segment with oblique 

 stripes of light hair at sides, but no apical 

 band 1 .
