elliptical, elongated, abdomen rounded, with legs and antennae 

 (I.e., pi. viii., tigs. 8-20). 



Of C ylindrocoGCus (pi, ix.) the female is cylindrical, sides 

 parallel, truncate in front, rounded behind, of red colour , 

 antenna; short, conical, only the anterior legs developed, remainder 

 merely indicated by dark patches. Larv?e with six long legs and 

 two anal setse. 



In Carteria the thoracic part of the female is very large, sub- 

 quadrate (the abdomen being very much and suddenly contracted, 

 very much shorter than the former, and truncate), with two 

 tubes and a horny spine dorsally, but without legs and antennae. 

 Colour red. The larvte possess antenna and long legs (I.e., pi. xii., 

 figs. 1-10). 



Mr. Maskell's descriptions and figures are exceedingly clear 

 and painstaking, and T am very much obliged to him for his 

 courtesy in remitting to me separate copies of his very valuable 

 and authoritative papers. 



Taking into account only what appears to be leading general 

 characteristics, the family, as far as now known, may be 

 synoptically epitomised as follows : — 



Family BRACHYSCELID.E. 



Females large, inhabiting through life singly woody or spongy 

 galls of more or less regular or symmetrical form, or rarely covered 

 only by thick, waxy tests. Male larvae in separate small galls or 

 associated with the females ; adults two-winged, minute. 



1. Galls woody or spongy (on Eucalyptus, Casuarina, 

 Beyeria). 



2. Galls woody, developed in branches and twigs. 



3. Female provided with legs, completely or partially. 



4. Female provided with complete set of legs, three-jointed. 

 (Body oval or fusiform ; antennae very short ; on Eucalyptus 

 and Beyeria ?) Brachyscelis, Schrader. 



4.4. Female provided with incomplete set of legs, remainder 

 indicated by dark spots. (Body cylindrical ; antennae short, 

 conical ; on Casuainna.) Cylindrococcus, Maskell. 



3.3, Female w^ithout legs (on branchlets of Casuarina). 

 4. Body of female globular ; antennae distinct. 



Sphaerococcus, Maskell. 



4.4. Body tadpole-like, with two tubercular appendages, and a 

 horny spine dorsally ; antennje absent. Frenchia, Maskell. 



2.2. Galls spongy or leathery (on leaves of Eucalyj^tus). 



3. Legs present in the female ; hindlegs very long, remainder 

 obsolete. (Body round anteriorly, tapering much behind ;
