NEW SPECIES OF COCCIDAE FROM AUSTRALIA.

Nymphal pellicle (fig. 13, a) globose and irregularly tumescent ; densely chitinous, 

 ochieous brown. The posterior extremity (fig. 13, b) bears a hinged semicircular 

 plate covering a large aperture through which the larvae make their escape. The 

 marginal area of this plate is marked with a polygonal cellular pattern. Length, 

 0-65 to 1*0 mm. 



Male puparium elongate, narrow, compact, flat ; white ; uncarinated ; the larval 

 pellicle ochreous, dehiscing circumferentially (as in the genus Aspidiotus), the two 

 members being conspicuous at the anterior extremity, on the dorsal and ventral 

 surfaces of the puparium respectively. Length, 115 mm. 



Fig. 13. rroiodiasjpis anomalaf Green, sp. n. ; a, nymphal 

 pellicle, X 41 ; b, posterior extremity of pellicle, X 210. 



Victoria : S. Morang, Dixon, on bark of Acacia sp. (C French, No. 109). 



Cockerell erected the genus Protodiaspis to contain Diaspine species " secreting 

 no distinct scale, but the females enveloped in cottony secretion, the male pupae 

 resembling those of Diaspis. No grouped circumgenital glands " — ^to all of which 

 •characters the present species conforms. It is also clearly congeneric with Fiorinia 

 syncarpiae of Maskell — a species that Cockerell proposes to refer to Protodiaspis. 

 My Fiorinia secreta (" Cocc. Ceylon," I, PL xxxiii), which constructs no scale, but 

 inhabits a gall, bears many resemblances to P. anomala, Protodiaspis agrifoliae 

 of Essig is scarcely referable to this genus. The insect has a distinct — though very 

 .«^mall — scale, and possesses circumgenital glands.
