II I >S TORY. 



The first account I have been able to find of this species is 

 that of Geoffroy, in 17G3, a celebrated French ph^'sician and ento- 

 mologist, who made the following remark concerning the species: 



"This small species is quite fiat and oval. It is of a clear brown 

 color and has in the middle a lengthy brown and richly colored 

 stripe, on both sides of which are stripes of a white ash color. It 

 is found on the underside of the leaves of the maple." 



The next account is a brief one by Fourcroy in "Entomologia 

 Parisiensis" 1785, 12% and is only an extract of Geoffroy as Chermes 

 aceris, T. I. p. 230. Also Latreille ''liistoire naturelle du Crust, et. 

 insect" Paris, (1804) Vol. 12, p. 389, makes a repetition of Geoffroy. 



Curtis in the Britanic Entomology gives the male of Lecanium 

 for that of coccus — AVestwood likewise, m his Introduction to Ento- 

 mology 11, p. 44G^ seems to have described the male of the Leca- 

 nium. 



"V. Signoret in his "Essai sur les Cochenilles" (1875) p. 329, 

 330 gives, under the name of Pseudococcus aceris, a short description of 

 the young larvae and grown female, but says the male is not known 

 to him. In America I find nothing written on the subject, and 

 neither can I learn of specimens in any of the collections. Letters 



I would like to return thanks to Dr. H. A. Hagex, for his klmlncss In assist- 

 ing me in obtaining the History of the Speciea.
