[Dec. 
I wish to extend my sincere thanks to Dr. Bequaert, 
Curator of Insects at the Harvard Museum of Compara- 
tive Zoology, for allowing me to study the material and 
for the aid which he furnished me during my study. I 
also wish to thank Mrs. Leonora K. Gloyd who read this 
paper and gave me many helpful suggestions about it. 
Note on the Type Specimen of Bagous sellatus Le- 
conte ( CoLEOPTEPtA : CuRCULioNiDAs). — Leconte’s descrip- 
tion of Bagous sellatus (Rhyne., p. 184) mentions that the 
elytra have “the striae deep, interspaces convex, first, 
third, and fifth more elevated, the last terminating in a 
large conical tuberosity, which is surrounded by a black 
cloud.’ ’ Blatchley (Rhyne. N. E. Am., p. 236) rede- 
scribes the species and states, “sides and tips of elytra 
ash-gray, leaving a large, elongate triangular space 
black. ’ ’ 
In 1942, when examining the type for Prof. Tanner, 
the present author subjected the specimen to degreasing 
in order to see the structural characters more easily. At 
this time the black cloud or spot disappeared, indicating 
that it had been merely an oil spot. It had been so sym- 
metrical that it had misled both discriminating students. 
The description stands on the basis of structural char- 
acters, the specimen now being entirely ash-gray. Any 
further specimens placed in this species because of pos- 
sessing a black spot will undoubtedly turn out to be of 
another species. — Floyd G. WepvNer, Biological Labora-
