PARASITES OF THE LARVA OF LACHNO-
STERNA FUSCA. In an item quoted in
PSYCHE, v. 4, p. 211, from Science record, Mr. Otto Lugger is reported as saying that "Tz'phia lays its eggs in the larva ofLacJno- sterna fusra," and the larva "when nearly mature eats the white grub." Further, that the eggs of R/;i/z'å´phoriis a secondary para- site, "become fastened to the TzyJia" These statements are not strictly accurate. The conjecture in my 6th Missouri 'eport,I p. 123- 126, that the Tifhia larva preys externally on that of Lachnosteriza, I have since veri- fied. and of courseit begins feedingas soon as hatched ; while it would be quite exceptional for Rhipipliortis to lay its eggs on Tifihiia. The probability, as stated in the report cited, is that the eggs are deposited on flowers fre- quented by TipJiia, to which the triungulin fastens and by which it is carried into the ground. It would be interesting to know
whether Mr. Lugger speaks from observation or conjecture.-C. V. RILEY, at meeting of Entomological society of Washington, 6 Nov. 1884.
FOOD-PLANTS OF PULVINARIA INNUMERA-
BILIS. On p. 338 of J. D. Putnam's "Bio- logical and other notes on coccidae" [Psyche. Rec., no. 19891, it is stated that Mr. Putnam has observed Pulvinaria innumerabilis in great abundance on Acer dasyca@unz, A.
.sacc/iari?zu?iz, Neynndo aceroides and Tilia eurojhea, on each of which it thrives well, best on the Negundo, but least on A. sacchn- rinum. Mr. Putnam knew personally of the occurrence of this species also on Robinid jseudacacia, Vitis Labmsca and Rhus glahra, in the vicinity of infested maples. In one instance he found a single undersized speci- men, with its "nest," on Vitis rz'pda, more than 800 metres from the nearest infested Acer. He adds Rosa and Fagus to the list of food-plants, on the authority of S. S. Rathvon, who found it once on each of these 1 PSYCHE, Rec., no. 39.
plants, and mentions with doubtful credence the opinions of Emily A. Smith and C. V. Riley that they had also found it on Salix, Maclura, ~uercus, Ulmus, Platanus, Ribes, Euonymus and CeZtis. It undoubtedly occurs in very great abundance on Maclzira hedges in Washington, D. C., as I have observed. On the 30th of June this year (1884) I
received from F. R. Rathbun, of Auburn, N. Y., three twigs of Ulmus, gathered on the 28th, in Auburn, bearing respectively I, I and 3 specimens of mature Pulvinaria innz~mera- bilis, with fully developed nests, from which the larvae have since hatched in great num- bers. These all came from one tree. In
sending specimens previously, Mr. Rathbun wrote that "the maples [Acer] especially have the silky pussys or cocoons to a large extent, and they are invariably found on the under sides of the twigs. Sometimes they are arranger thickly, in rows, and again singly." Mr. Putnam says "there is enough evidence to show that this insect is capable of thriving on quite a variety of food-plants. and in the cases where it has been directly in- troduced from the maple there is no question of its identity." The specimens referred to in this communication will be deposi- ted in the Museum of comparative zoology at Cambridge, Mass., where they are more certain of good care and of being accessible to students than in any other collection of national extent in the country.-B: PICK- MAN MANN at meeting of Cambridge ento-
mological club, 10 Oct. 1884.
