domen, the closer and larger punctures of mesothorax, and the 
irregularly sculptured base of metathorax. The scanty hair on 
apical half of abdomen is white in S. latifrons, yellowish in S.

pale ferruginous apically; apical margin of first abdominal

subcircular; clypeus shining, but strongly and quite closely 
punctured, not at all hidden by hair; scape short; third 
antennal joint about one-third as long as fourth; surface of 
flagellar joints microscopically reticulate; front and sides of . 
face with much white hair, not however hiding the surface; 
mesothorax with very large, rather dense punctures, partly con- 
fluent in rows; tegule rufotestaceous, with the margin pallid; 
wings hyaline, the apical field dilute brown; stigma ferru-

A second specimen from the original locality agrees, and I 
now believe that this is a quite distinct species. The first ab- 
dominal segment is reddish orange, with a black spot on each 
side. :
