true and neoteinic, in the United States, and his material forms an 
important auxiliary to later investigations. Much of Hubbard’s col- 
lecting in Florida and Arizona was done in company with Mr. E. A. 
Schwarz, of the Bureau of Entomology, who has since published “some 
of his observations on the habits of termites in southwestern Texas. 
The Rey. F.L. Odenbach,S.J.,of Cleveland, Ohio, has studied the hab- 
its of our native species of termites since 1893, and has contributed 
many manuscript notes. Mr.L.H.Joutel,of New York, has studied the 
habits of our common species? and has contributed some unpublished 
notes. Dr.H.McE. Knower,‘late of Johns Hopkins University ,in 1894 
published new and important contributions on the embryology of ter- 
mites (EKutermes). His observations are not in accord with those of 
Bugnion, since he determined that the nasutus develops from a 
worker-like larva nearly as large as a young nasutus, having 13 
joints to the antenna and worker-like head and jaws. This worker- 
like larva had a small head gland with no “corne frontale” on the 
outside of the head, although sections show essentially the same 
structure in the gland as that of the nasutus. Mr. C. Schaeffer, of 
Brooklyn, N. Y., was the first to record ¢ the presence of a fertilized 
true queen of flavipes in a colony. The researches ¢ of Dr. Harold 
Heath, of Stanford University, Cal., on the habits of California ter- 
mites confirm the statements of Pérez and Perris that some colon- 
izing individuals of Leucotermes lucifugus succeed in establishing new 
colonies. Mr. Nathan Banks, of the Bureau of Entomology, has 
contributed several articles on our native termites, and has described 
a new species of Leucotermes (virginicus) / from the eastern United 
States. Mr. C. L. Marlatt, assistant chief of the Bureau of Ento- 
mology, has described the distribution, life history, and destructive- 
ness of flavipes in the United States and figured the castes. Mr.
