Dr. Sylvester D. Judd reported to the writer that of six specimens 
of the rough-winged swallow (Steligidopteryx serripennis) shot at 
Marshall Hall, Md., July 8, 1898, three had eaten this beetle, as shown 
by an examination of the contents of their stomachs. 
The Seed-stalk Weevil (Ceutorhynchus quadridens Panz).—After the 
publication of the writer’s note (Bulletin 23 n. s., p. 51) on the identity 
of this species with (C. servesetosus Dietz., reference was noticed to the 
same species in Mr. M. V. Slingerland’s Bulletin 78, of the Cornell 
University Agricultural Experiment Station, page 503. The remarks 
in question form a footnote in the discussion of the cabbage-root 
maggot, and the statement is made that this weevil is a very serious 
pest in the great cabbage seed-growing region on Long Island. To 
make certain of the identity of the species, Mr. Slingerland kindly 
sent specimens from Nattituck for comparison with named specimens. 
Pemphigus sp.—February 14, 1901, Mr. S. A. McHenry, of the 
Beeville substation of the Texas Experiment Stations, sent specimens 
of an unknown species of Pemphigus, stating that it was doing injury 
to the roots of cabbage in the vicinity of Beeville, some of the fields 
being reported as totally destroyed. One person who furnished 
material wrote that as soon as the lice attacked the roots of the plants 
the leaves turned yellow and the plants soon died. He stated that 
several fine patches had been utterly destroyed. 
Wasps as destroyers of cabbage worms. During July and August, 
1900, different species of wasps, and particularly Polistes pallipes St. 
Farg., were observed hovering about worm-eaten cabbage plants in 
several gardens. In one garden they were always numerous in the 
western part of a large patch of cabbage. At the extreme eastern end 
the plants were more or less protected by shade, particularly in the 
afternoon. At this end larve of Plutella, Pionea, and Plusia were 
at work, but no Pieris, while in the sunshiny places, where the wasps 
were flying freely, no larve at all could be found, although holes in 
the leaves were evidence that they had been present. The wasps 
were carefwly watched on several occasions, and it was plain from 
their manner of work that they would first destroy the imported cab- 
bage worms, afterward the loopers, and that the Pioneas would be the 
last to be captured, as these bored directly into the hearts of the cab- 
bage, concealing themselves between two leaves in such manner that 
it would be difficult for the wasps to find them in the cursory manner 
of their search. The Plutellas, owing to their smaller size, might pos- 
sibly evade discovery. 
Singularly, in spite of utmost endeavors, it was impossible to detect 
a wasp in the act of destroying a cabbage worm, nevertheless circum- 
stantial evidence was so strong that the writer felt no hesitation in 
attributing the absence of the ‘‘ worms” in the sunny portion of the 
garden to the presence of the wasps. The ‘* worms” working on plants
