been impressed with the belief that there are two species of Pulvinaria 

 to be found upon the maple tree, the form occasionally found upon the 

 leaves being not so large, the secreted cotton mass somewhat depressed, 

 faintly bilobed, and transversely undulated or indented. 



The receipt during June of the present year (1898) of specimens of 

 a Pulvinaria on the leaves of a silver maple from Prof. Hunter Nichol- 

 son, of Knoxville, Tenn., and which plainly differed from P innumera- 

 bilis, and resembled at the same time perfectly the Walsh-Eiley figure 

 of Lecanium acericola, induced the writer to search* for the original 

 specimens in the old Eiley collection. They were found, and the accu- 

 racy of the figure in the American Entomologist was perfectly estab- 

 lished* the identity of the species received upon leaves from Knoxville, 

 Tenn., with the American Entomologist figure was also established, 

 and that the insect is specifically distinct from Pulvinaria innumerabilis 

 Eathvon was without difficulty ascertained. The description by Walsh 

 and Eiley, as has already been stated, was inadequate, yet the accurate 

 figure amply suffices to carry the name, and this smaller leaf-inhabiting 

 Pulvinaria must in future be known as Pulvinaria acericola (Walsh 



and Eiley), its known habitats being Davenport, Iowa- , Indiana 



(B. W. McLain), cf. American Entomologist, Vol. II, page 14 • Lancaster, 

 Pa. (Eathvon), and Knoxville, Tenn. (Nicholson). 



The writer has the species under daily observation at Washington, 

 and expects at an early date to publish its full life history, which must 

 present some interesting variations from that of P. innumerabilis. 



The paper was discussed by Mr. Hopkins, who referred to a species 

 occurring on the yellow locust in West Virginia. 



Mr. Smith stated that he had been puzzled with these insects and that 

 in New Brunswick, this season, the only species present was the one 

 occurring on the leaves. 



Mr. Howard referred to the great range of Pulvinaria, innumerabilis, 

 extending from the Mississippi Valley eastward, and commented on the 

 inaccuracy of the old records. 



The committee appointed at the last session to nominate officers for 

 the ensuing year presented the following names: 



For president, C. L. Marlatt. 

 For vice-president, Lawrence Bruner. 

 For second vice-president, C. P. Gillette. 

 For secretary-treasurer, A. H. Kirkland. 



The persons nominated were duly elected to the offices named. 

 On motion, an evening session was determined upon to begin at 8 

 o'clock.
