THE CANADIAN ENTOMOLOGIST 



Genus Cissococcus Ckll. 



Cocciclae referable to the subfamily Coccina^. Adult female with the anal 

 plates borne at the apex of a low prominence, their dorsal surface beset with 

 numerous small spines; antennae and legs present but extremely small; stigmatic 

 depressions apparently lacking, their presence not indicated by differentiated 

 spines. First stage larva likewise without differentiated stigmatic spines. 



Type of the genus Cissococcus fulleri Ckll. 



Notes. — The original description of this genus is much in error. The 

 author states, "Belongs to the Eriococcini. Larva typically Eriococcine, with 

 rows of dorsal spines. . . Adult . . . with a pair of plates simulating 

 those of the Lecaniinae." The larva is in all respects of the type usual in the 

 Coccinae ( = Lecaniinae) and is entirely without dorsal spines. The anal plates 

 of the adult are very much of the type seen in Ceroplastes, except for the numerous 

 spines on the dorsal surface. In spite of the gall-making habit the genus is 

 indeed possibly close to Ceroplastes. 



The species described by Ehrhorn as .Cissococcus ? oahuensis has nothing 

 to do with C. fulleri and has quite properly been referred by its author to a new 

 genus. *■•

My single adult specimen is not in sufficiently good condition to permit 

 adding much to the description already given for the genus. The anal plates 

 (Fig. 3C) are rather long, the lateral margin rounded, the tips quite pointed, 

 resembling in this respect the type of plates seen in Ceroplastes. There appear

to be no marginal spines. The antennae are extremely minute, with the number 

 of segments undeterminable; the legs arc likewise very small but possess the 

 normal parts. 



The first stage larva bears a marginal series of short, stout spines (Fig.
