the subapical pits well defined, eight on each side of median ridge; 
apical margin of tergite with five triangular teeth of uniform size, the 
distance between the lateral teeth slightly greater than the distance be- 
tween an intermediate and median tooth; seen from the side the ventral 
margin of the third tergite is straight. 
Greenish-blue, with a bluish reflection on third tergite, a copperish 
reflection on sides of second tergite, and a dark purplish spot around 
ocelli and one covering the median area of the scutum; antenna beyond 
third joint black; legs entirely green; wings brownish-hyaline; venation 
black; head, thorax and legs with sparse gray hair. 
Paratype females have the blue color of the body more pronounced 
than in the type and might be called blue-green. The subapical pits may 
be reduced to fourteen. 
Male. Length 6 mm. Agrees well with the above characterization of 
the female, but the end of the third tergite is more pointed and the 
apical teeth are lower and more obtuse.

Described from five females and one male collected by 
P. H. Timberlake. The type female was collected on the 
laboratory window August 15, 1916. The allotype male was 
collected September 10, 1916. Three paratype females were 
collected at Honolulu on May 15, 1918, May 15, 1920, and 
June 22, 1919. The other female is labeled “Ex Sceliphron 
cells,” “Diamond Head, Oahu, May, 1919.”
