minute species of Gamasidse, of a faintly yellowish color. They 

 were feeding on the eggs " (Pergande MS.). 



Gossyparia spuria (Modeer). 



Coccus uliiti, Olivier, Encycl. Meth., Vol. vi, 1791, p. 97. 

 This species was well figured by Re'aumur, and is the Coccus 

 ulmi, corpore fuMo, serico albo, of Geoffi'oy. Geoftroy'sname is not 

 a binomial, so the proper name of the insect is that given by 

 Modeer, which was in general use before Signoret's time. 



The Coccus alni Modeer, 1778, is a Lecanium, and has nothing 

 to do with Gossyparia; see Douglas, Ent. Mo. Mag., September, 

 1886, pp. 80, 81.
