bug, Zelus sp., collected on Agave plants near bean fields, were shipped to 
Birmingham, but the young nymphs, when reared at the latter place, refused 
to feed on Epilachna larvae. 
As to wild food plants: the large numbers of leguminous plants and 
trees were examined for Epilachna in Mexico, only two were found to 
harbor the beetle. One is a wild climbing bean, Phaseolus sp., abundant 
along streams, the other a wild weed known as beggar-weed, or tick trefoil 
(Meibomia sp.) The latter harbored large numbers of bean beetles of all 
stages, and was believed to be the bettle’s native wild food plant. 
This paper was discussed by Messrs. ALpricH, BRIDWELL, Howarp and 
ScHWARZ.

Notes: J. C. BripwEtu discussed the occurrence of the clover seed chaleid 
in the seeds of Astragalus. 
Some months ago the speaker had reported the discovery of Bruchophagus 
funebris in pods of a species of Oxytropis (O. lamberti), a genus closely related 
to Astragalus. It is now possible to record an additional instance of attack 
upon an Astragalus by a Bruchophagus. This was discovered in a specimen of 
Astragalus douglasti in the National Herbarium collected on June 25, 1891 by 
Coville and Funston near Tehachipi, Kern County, California, at an elevation 
of 1000 metres. The Bruchophagus was accompanied in its attacks by 
Acanthoscelides pullus (Fall) and had at first been mistaken for a Eurytoma 
parasitic upon the Bruchid. The material from its age and its condition 
after having been extracted from the seed is not in the best of condition for 
determination and in it Mr. Gahan sees certain apparent differences of 
sculpture and color which do not permit him to positively determine it as 
funebris and suggest its belonging to another species, the question of its 
identity requiring biological evidence for its answer. 
The finding of Bruchophagus in pods so different from the fruit of the pre- 
viously known host plants in Trifolium and Medicago as the compact ovoid 
pods of Oxytropis lamberti and the large bladdery membranous pods of A. 
douglasii does not seem so strange when it is recalled that the oviposition is 
done early in the development of the young pod. How far the finding of 
additional host plants of Bruchophagus will effect practical control remains for 
investigation. 
356TH MEETING 
The 356th meeting was held March 1, 1923, in Room 43 of the New National 
Museum, with Vice-President Dr. A. G. B6vine in the chair and 38 persons 
present. 
Mr. Rouwer, for the Executive Committee, stated that since the last 
meeting the Society had received a communication from the Secretary of the 
International Commission of Zoological Nomenclature requesting that a com- 
mittee be appointed to prepare preliminary reports on questions of Entomo- 
logical Nomenclature referred to the Commission. President Howard had 
appointed as the Society’s Committee, Messrs. Ronwrr, Herrnricu and 
BAKER; and since the announcement of the Committee the Commission had 
referred three distinct questions to its Chairman. 
I’. W. Poos was elected to membership in the Society. 
Program: 
R. E. Snoperass: The anatomy and metamorphosis of the apple maggot 
(Rhagoletis pomonella Walsh). 
The following generalizations probably apply to most of the Cyclorrhapha:
