( June, 



the " North American Entomologist," /. c, hj Miss Emih^ A. Smith 

 on Pseudococcus aceris, found but rarely on maple {Acer saccharinum) 

 in North America, and gives a description of it, avowedly derived from 

 the description by Miss Smith and Signoret, and which is mostly in 

 accord with that I have made from the examples before me ; but, as 

 I have previously noticed (cf., vol. xxv, p. 125, foot note), the species 

 is erroneously attributed to Geoffroy. 



Miss Smith, /. c, describes and figures the insect in all its stages, 

 the male (which was not known to Signoret) for the first time. The 

 only material discrepancy with Signoret's description that I notice is 

 in the lengtli of the tarsus of the $ imago, which is stated to be only 

 half that of the tibia (whereas Signoret says the tibia is three times 

 longer than the tarsus) ; but this may have been only a casualty of 

 observation, and therefore not alone sufficient to invalidate the identity 

 of the species. The position of the ovisac on the leaves instead of on 

 the trunks of the trees also deviates from the habit of our examples, 

 but this may not have been the general habit, and Comstock seems to 

 have had no doubt that the insect is Signoret's Ps. aceris. I may 

 note, however, that of Ps. mespili, Geoffr., Signoret says that the tibia 

 is only twice the lengtli of the tarsus, as in Miss Smith's species. 

 Miss Smith also describes and figures a Chalcid parasite bred from her 

 Coccids, as a new genus and species, Acerophagiis coccois. Mr. L. O. 

 Howard maintains the species, but merges the genus into Phopus, 

 Foerst. (Comstock's Report for 1880, p. 3G1). 



PsEUDOCOCCrS QUERCUS, n. sp. 



Adult $ . Yellow-brown, soft, tumid, broad-oval, anteriorly rounded, end of 

 body emarginate, with longish hairs ; anal lobes rounded ; anal ring with six hairs 



(Fig. 3) ; margin of body with shorter 

 hairs ; thorax with six deep punctures 

 in two parallel rows of three ; connec- 

 tion of thorax and body deeply incised 

 at the sides, segments all visible ; no 

 marginal appendages. These females 

 were enclosed in snow-white, dull, 

 smooth, narrow, elongate, semi-tubular 

 or flat-arched, thin, papery ovisacs, 

 nearly three times the length of the 

 enclosed insect, which was situate at 

 one end, where only was a little cotton 

 covering material ; the rest of the tube 

 full of loose, pale yellowish eggs. An-
