Fumigation’ arainst rice weevil:in corn.--S. BE. Mc@lendon of -Thomas— 
ville, Ga., reports that at the request of many farmers inquiring as 
to the value of benzol as a fumigant, he fumigated several lots of corn 
during October, but the results were not satisfactory, as adult weevils 
(Sitophilus oryza@ L.) heve emerged from fumigated samples. Weevils~ 
in all stages were apparently killed in one lot of corn by two successive 
furigations and the odor and taste of meal later made from the corn were 
not affected. aa 
Notes on flour—mill insects.--N. E. Good, in his investigations of 
flour—~mill insects during December,has found several snecies of rare or 
little known insects in flour mills and feed stores in and about Wash— 
ington, D.C. Quite a mumber of Murnidius ovalis Beck (family Murmidiidad, 
avery small, rounded, black beetle seldom found except in vegetable 
refuse, were taken for rearing purposes from some dry, shelled corn pur-— 
chased -in oa local feed store. Two predacious beetles of the family 
Histeridae, Carcinops l4—striata Steph. and Dendrophilus punctulatus 
Say, have been found in fairly large numbers in the basements of nearby 
“flour mills in both Maryland and Virginia. These beetles have usually 
been found associated with the well lkmown beetles Tenebrio molitor L., 
T. obscurus Fab., Sitophilus granarius L., Palorus ratzeburgi Wissn., 
and Alphitophagus bifesciatus Say, and it is probable that they aid 
materially in keeping down: the numbers of these pests. 
One of the hairy fungus beetles, Mycetophagus bipustulatus Melsh., 
which superficially appears very much like a large specimen of the 
two-banded fungus beetle (Alphitophasus bifasciatus Say), has been 
taken on several occasions in the basements of nearby flour mills in 
Maryland. This is thought to be the first record of this species from 
a flour mill, 
Another very interesting and unusual beetle, Aglenus brunneus Gyll., 
of the family Colydiidae, has been taken in a local mill in Virginia 
and in another in Maryland. Although of no economic importance, this 
species is interesting in that it is totally blind. In both cases this 
beetle was found during a casual examination of waste grain lying on 
dirt floors in dark and musty corners of the basements ofthe flour mills. 
This is also thought to be the first record of this species in. flour 
mais. 
IDENTIFICATION AND CLASSIFICATION OF INSECTS 
A. G. Boving reports that in adcition to the rare larvae. of the 
water beetle Sncyronyx variegatus Germ., reported on in the December 
(No. 235) 1 Monthly Letter, the collection has recently received, from 
the same source, the larvae of five other species of the systemati-
