THE CANADIAN ENTOMOLOGIST 63 



locu.ar pores, of tlio type shown in Fig. C are very numerous and unusually 

 largt and conspicuous. The antennae (Fig. D) are relativeh- cjuite small but 

 are v> ell developed and show six or seven segments. The legs (Fig. F) are like- 

 wist relati\ely quite small, and the coxa* of the posterior pair show many small 

 pori-. 



The first stage larva likewise bears numerous large, trilocular pores and a 

 few rmall, conical spines. The anal ring is large and cellular and bears six 

 seta- The anal lobes each bear a single seta which is about as long as those of 

 the ..nal ring. There are no indications of cerarii. 



Material examined. — Two slides received from Professor Cockerell and 

 labe cd merely as "types" of this species and a slide mount of a single individual 

 received from Mr. F. E. (ireen and said to be from the type material of the 

 spec:es. It is from the last that the accompanying figures were made. 



There has e\idently been some mixing of material in connection with this 

 spe< fs for another slide received from Professor Cockerell and likewise labeled 

 as a type" of this species represents some Lecaniine form. 



Through the kindness of Professor Cockerell I have had the privilege of 

 exar-.ining a slide labeled as a "type" of P. perganderi. The two species are 

 very >imilar but I am not prepared to say whether or not they are identical. 



Genus Cissococcus Ckll. 

 Brain^ has considered it necessary to erect a new subfamily, the Cissococcina, 

 for :nis genus. As I have previously pointed out in this series of notes this 

 gen;.- is a Lecaniine form showing certain affinities with Ceroplast-es. The 

 stafment that the anal plates are four in number is erroneous, the supposed 

 out'.: pair being nothing more than the chinitized area upon which the anal 

 platt- are borne. The arrangement is strictly the same as that seen in Cero- 

 pkms, and a comparison with the latter genus will dispel any thought of the 

 necfce>ity of a new subfamily for Cissococcus. 



Genus Howardia Berlese and Leonardi.

There appears to be some confusion concerning the type of this genus. 

 LnJ-r the original description there were included three species, Chionaspis 

 hicUr. is Comst., C. cilri Comst. and a species there described as new under the 

 nair.v of Honardia elegans, this last being a synonym of Diaspis zamice Morgan. 

 No :>"pe was designated. Cockerell (1896) in a paper which seems to have 

 beer, omitted by the Fernald Catalogue, designates as type, Chionaspis hiclavis 

 Corr.^t. This paper appears to have been overlooked by Paoli (1915) who 

 statt> that //. elegans (= zamice) is the type of the genus and he names^a new 

 gen•J^. Megalodiaspis, for Chionaspis biclavis. 



!t is evident that the type fixation made by Cockerell must stand, and 

 tha: Megalodiaspis must be placed as a synonym of Hoivardia.
