several males, and subjoin their description, which is not given 

 by Comstock. 



Male puparimn white, narrow, flattish, indistinctly cari- 

 nated ; length about -g^in. 



Adult male yellow, of the normal Diaspid form ; length of 

 body about ^in. Antennas of ten joints. The abdominal 

 spike is almost as long as the body of the insect. 



My specimens are from Mr. Koebele, on palm, Australia, 

 and also on Leptospcrmum sp., growing apparently close to 

 the palms. 



Fiorinia syncarpiae, sp. nov. Plate XI., figs. 14, 15. 



Females not excreting any definite and separate puparium, 

 but congregated in numbers under a general mass of thin, 

 whitish, curling, cottony threads, in which the yellow oval 

 pellicles appear scattered. The two pellicles form an ellip- 

 tical, somewhat convex, scale ; length of second pellicle 

 about -hrin. When viewed bv transmitted lisht it is seen

that at each end of the oval scale there are antennas 

 and a rostrum ; it would seem, therefore, that in the meta- 

 morphosis from the larval stage the insect becomes reversed, 

 and also that the second-stage female preserves her an- 

 tennae. No abdominal lobes are to be made out on the second 

 pellicle. 



Male puparium rather more definitely formed than that of 

 the female ; form subcircular, flattish, consisting of loose 

 white cottony fibres ; average diameter about ^jin. Pellicle 

 of larva central, yellow. 



Adult female brownish-yellow, elongated ; length about 

 J^in. Abdominal margin deeply serrated and irregular, ter- 

 minating in two conspicuous median lobes separated by a 

 depression, with one smaller lobe on each side. The median 

 lobes are prolonged into scaly processes with deeply-serrated 

 extremities, and on the other lobes, and here and there on the 

 margin, are smaller similar scales, and also a few spiny hairs ; 

 the whole abdominal region has thus a very irregular and 

 jagged outline. No groups of spinnerets, but a few scattered 

 single ones. The rostral setae are very long, and consist of six 

 separate tubes. 



Male pupa elongated-oval, the abdomen terminating in two 

 median rectangular lobes with foliated extremities, and one 

 very small lobule at each side ; several scaly hairs on the 

 margin. Towards the end of the pupal stage the rudimentary 

 eyes, antennas, and wings may be detected in process of 

 formation. 



Adult male brown, presenting no special features ; length 

 of body about ^yin. The abdominal spike is rather more than 

 half as long as the body.
