[UnknowTi locality.] 
Amazon, one hundred knots west of Santarem. One male. 
Pacaya, Peru. September, 1912. One male. 
This well known species already has been recorded from as far 
inland in the Amazon valley as Santarem, but the Pacaya speci- 
men is the first one reported from upper Amazonia.

The synonymy of Bucrates cocanus with hrevicauda is clearly evi- 
dent from an examination of the material here studied, and from 
the original description of Bolivar’s species. The name cocanus 
was based on the male sex, while the type and previously unique 
specimen of hrevicauda is a female. This individual, belonging 
in the Scudder Collection at the Aluseum of Comparative Zool- 
ogy, is now before us. It is in fairly good condition and measures 
as follows: length of body, 32 mm.; length of pronotum, 9.1; 
greatest caudal width of pronotal disk, 6.4; length of tegmen, 41.8; 
length of caudal femur, 22.5; length of ovipositor, 14. The series 
before us shows there is considerable variation in size in both 
sexes, but this is more pronounced in the male sex than in the 
female. Apparently all the specimens have been immersed in 
some liquid preservative, which has either destroyed or injured 
the general color tone, but in all the paired blackish pronotal 
lines are at least in part indicated. The black of the clypeal 
suture, on the internal portion of the mandibles, on the proximal 
antennal joints and on theventral margins of the antennal scrobes 
is conspiciously and solidly indicated in all the specimens, except 
that the clypeal sutural marking occasionally weakens mesad.
