and very minute and sparse punctures; clypeus prominent, with an obtuse 
but strong median ridge; at each side of the clypeus, toward the apex, is a 
small shining black tubercle, and the apical margin is broadly pale yellow, 
the labrum, and mandibles except apex, being of the same color; hair of 
face and vertex strongly tawny, of cheeks dull white; scape yellow in front; 
flagellum dark ferruginous above, light ferruginous beneath, the apical 
half crenulate; scutellum smooth and shining, with very minute. punctures; 
pleura roughened anteriorly, strongly striate posteriorly; metathorax 
without any defined enclosure or sharp margin round the apical truncation, 
the whole surface strongly striate, the striz oblique, those on the trunca- 
tion approximately at right angles to those on the part above; sides of 
metathorax with pale yellowish coarsely plumose hair; tegule pale rufo- 
testaceous; wings rather dusky, stigma and nervures dark brown, first r. n. 
joining second s. m. far beyond the middle; legs ferruginous, the hind 
femora greatly swollen, dusky above, with a broadly triangular tooth be-

Melissa friesei Ducke. 
3. Brazil (W. H. Bates); F. Smith collection. Brit. Museum. Although 
long ago discovered by Bates, this beautiful species was not described until 
1902. The specimen before me has the abdomen brilliant blue; Ducke’s 
description says “nigroceruleus.” The bifid spur of the middle tibia has the 
anterior branch quadridentate, a fact not indicated by Ducke, and the 
specimen is a little smaller than Ducke’s type. It is just possible that ac- 
tual comparison would indicate that our insect is separable, but except for 
the points mentioned, the structural and color characters are all in accord 
with M. friesei. M. maculata Friese must be closely allied. 
M. decorata Smith was described from “Brazil.” The original 
specimens were taken by Bates in S. Paulo.
