vag tae 
matter of dispute for some tine, It was fornerly placed as a subfamily 
of the Noctuidae. Recently Dr, Forbes placed it under the Pyraloidea, 
upon characters of the adult thorax and the pupa. The larvae support 
his assignment. They are typically pyralid in all structural charac-— 
ters. Upon the sum of its characters (adult;: pupal, and larval) the 
Hyblaeidae must be considered as a Cistinct family near Pyralidae but 
not within that family as now defined: “Immature stages of Hyblaea are 
rere in collections and the specimens received from Mr. Gardder are all 
that we have in the National collection. 
In a collection of Tabanidae from A. Earl Pritchard, of the Okla~ 
homa A. and M. College, Alan Stone has identified three ewamples of 
Tabanus carolinensis Macq. from Atoka, Okla. This is a western re— 
cord for the species. 
Cornelius B. Philip of the Public Health Service Laboratory at 
Hamilton, Mont., recently spent a few days at the Museum, working with 
Doctor Stone on mosquitoes and Tabanidae. 
A series of specimens, supposedly Microbracon brevicornis (Wesm.), 
which were recently received for verification of the determination, 
contained individuals that appeared to be inseparable from the closely 
related M. hebetor (Say). M. brevicornis is best known as a parasite 
of the European corn borer; M. hebetor, as a cosmopolitan parasite 
of lepidopterous larvae infesting stored grain products and stored 
fruits. In an attempt to determine definitely if these two forms, 
which have been much confused, are actually distinct, C. F. W. Muese— 
beck had occasion to examine a considerable quantity of material from. 
several different sources. The following general conclusions may be 
stated as a result of his study: In the male-sex hebetor and brevi- 
cornis are frequently dndistinguishables; but, except perhaps for ex-— 
tremely rare cases in which complete intergradation may occur as the 
result of unusual” influences, the females appear to be definitely separ-— 
able. Accordingly it is believed that M. hebetor and M. brevicornis 
are to be considered as distinct races at least, if not distinct species, - 
L. J. Milne, a Harvard University graduate student working on 
caddisflies with the intent ultimately to prepare a handbook on the 
North American species of this order, spent several days early in Jan-— 
vary with A. N. Caudell, going over the Trichoptera collection in the 
National Museum. 
H. E. Ewing has established a second record for the southern dog 
louse, based on his identification of two specimens collected at Mc- 
Alester, Okla. The species’ was described in 1929 by E. A. McGregor 
as Trichodectes floridanus, from specimens.:collected in Florida.
