Fonscolombia radicum-graminis (Fonse.). 



Fonscolombia graminis Licht., Ent. Mo. Mag., 1877, July, pp- 34, 35. 



This insect, described by Fonscolombe in 1834, is found in 

 France at the roots of cereals. The 9 has G-jointed antennje, 

 and the ^ is apterous. Lichtenstein suggests that this may be the 

 Coccus phalaridis, but this is at present doubtful. Should it be 

 phalaridis, it will belong to Coccus L.; but otherwise Lichtenstein' s 

 genus Fonscolombia is valid, and has priority over Pseudochermes 

 and Apterococcus, proposed for a congeneric species. 

 Fonscolombia fraxini (Kalt.) 



Riper sia {Apterococcus) fraxini (Newst. ). 



This insect was first described by Kaltenbach in J 874. In 

 1895 Nitsche proposed for it the subgeneric name Pseudochermes. 

 Newstead, when describing the insect as new, used the same specific 

 name as that of Kaltenbach. 

 Phenacoccus mespili. 



Signoret in 1875 described this insect for the first time, but 

 called it Pseudococcus mespili Geoffroy. The Chermes mespili serico 

 alho of Geoffroy, as well as the Coccus mespili Gmelin {Syst. Nat, 

 1788), based upon it, are manifestly referable to Pulvinaria. 

 Geoffroy says his insect appears not to differ from his Chermes 

 carpini serico alho, which is also a Pulvinaria. Signoret also cite& 

 Fonscolombe' s supposed Coccus cratcegi, described iu 1834, but 

 that is also a Pulvinaria. Signoret has suggested that the Cocem 

 pjruni Burm. , 1849, may be Pseudococcus mespili. The description 

 of Burmeister is quite inadequate to demonstrate this, and differs 

 in the statement that the insect is greenish gray, P. mespil 

 Sign, being reddish. The Phenacoccus is therefore nameless, but 

 it is here proposed to use for it the name mespili, which will not 

 conflict ^vith Geoffroy' s name, the latter pertaining to a different 

 genus. 

 Phenacoccus (?) farinosus (Gmel.). 



Coccus farinosus alni, DeGeer, Mem , Vol. vi, 1776, p. 442, pi. 28, figs. 

 17-20. 



Coccus farinosus, Gmelin, Syst. Nat., Ed. xiii, 1788, p. 2220. 



This is a Dactylopiine found on the alder ; clear, rather reddish, 

 brown, mealy-farinose, eventually covering itself, except the head, 

 with a cottony sac, in the hind part of which the eggs are laid. 

 In the subadult stage it has short lateral tassels, but no long caudal
