252 THE CANADIAN ENTOMOLOGIST 



four cr five segments. Anterior to these segments they appear only toward 

 the lateral margins. Abdomen with a few rather stout, conical spines arranged 

 in transverse rows. Spiracles not unusually large, associated with a few yery 

 small, circular pores. Behind each of the posterior pair there is a small, cribri- 

 form plate cr tubercle. 



Penultimate stage. — In form resembling the adult but without the con- 

 strictions between the abdominal segments, without the pores in the inter- 

 segmental furrows and less heavily chitinized. Antennae and legs present, the 

 fcrm^er (Fig. 35C) quite stout, six- segmented, the latter of ordinary character, 

 the tibia somewhat shorter than the tarsus, the claw with a small tooth. Anal 

 ring as in adult but at the tip of the abdomen. Body with a few, scattered 

 conical spines and a very few, small, multilocular pores. 



First Stage. — Antennae (Fig. 35D) six- segmented, the last three segments 

 each with one or two long, stout, curved spines. Anal ring with six slender 

 setae. Anal lobes each with a single slender seta and two short spines. Derm 

 with a few small, stout spines and multilocular pores. 



Specimens examined. — From Eucalyptus, New South Wales, Australia. 

 Collected by Kcebele and received by me from Mr. Ehrhorn. They agree in all 

 respects with the original description. 



Notes. — While it is possible that this species is not strictly congeneric with 

 K. parvus, I am inclined to think that it belongs in the group with that species. 

 It will at least rest better in Kuwanina than- in Sphaerococcus. It differs from 

 K. parvus in the nature of the first stage and in the entire absence of the tubular 

 ducts which are a conspicuous feature of K. parvus, while it agrees in the presence 

 of the pair of cribriform plates or tubercles behind the posterior spiracles. 



Genus Eremococcus, new genus. 

 Coccidae referable to the subfamily Dactylopiinae (of the Fernald Catalogue) 

 but of doubtful position within this group. Adult female apodous and with 

 the antennae reduced to mere unsegmented vestiges; anal orifice simple, minute, 

 borne on the dorsum; dorsum of adult flat, heavily chitinous, venter mem- 

 branous; mouth-parts with internal framework unusually large and heavily 

 chitinized; first stage larva with anal ring small and simple as in adult, with the 

 antennae composed cf a single very large segm.ent (and possibly one cr two 

 minute basal segments), with the anal lobes obsolete and not marked by a long 

 seta. Dorsal ostioles lacking; tubular ducts lacking. 

 Type cf the genus, Sphaerococcus pirogallis Maskell. 



Notes.— I am unable to throw any light on the relationships of this genus. 

 I would suggest that possibly its nearest relatives are to be sought for in such 

 fcrms as Sphaerococcopsis and Pseudoripersia.

Habit. — Enclosed within a small, pear-shaped gall which has a minute 

 opening at one side near the base. The insect lies in a saucer- like elevation 

 at the far end of the gall. 



Morphological characteristics. — In addition to the characters given in the 

 description of the genus I may add the following. The female of the early 

 adult stage is entirely membranous but at maturity the dorsum becomes heavily
