From Garces, Arizona, August (Biedermann). 



Pompiloides estellina new species. 



]\Iale. — Jet black; face below and at sides of the antennae silvery, some

From National City, Calif., 15 May (Van Duzee). Related to P. 

 ongularis, but in that species the second discoidal cell is still shorter 

 and fully twice its length from the outer margin of the wing.

 each side at the tip of the metanotum. Clypeus truncate in front, antennae
