ab. In Australia, on Eugenia smithii. My specimenswere sent by Mr. Koebele from Sydney. I believe that this insect is here correctly assigned to thegenus Diaspis, although, in the absence of the male puparium,I do not positively assert it. I know of no Aspidiotus whichhas such an elongated form; and, indeed, the insect in itsgeneral shape resembles very much Diaspis rosa, Sandberg,though it differs entirely from that species not only in colour,but principally in the absence of a medial terminal depression,in the six abdominal lobes, and in the scaly fringe. As for Par-latoria, the case is different, and the fringe might possibly makeit approach that genus. But here, again, the form is muchmore elongated than that of any Parlatoria known to me.P. proteus, Curtis, varies somewhat, but never seems to getbeyond an oval form, and all the specimens which I have seenof it agree with Signorets statement that it is widest pos- ^nmsnqticm* f tm ^mhnt institute, Vol. xxv., Pl.xr ■■: • i oo

Further, in Parlatoria the fringe extends not onlyover all the pvgidial region, but also to the anterior abdominalsegments, while in D. fimbriata it is very short. I observe,also, that in Lows description of D. visci, Schrank (accordingto Comstock, Second Cornell Eeport, 1883), the scaly hairs inthat species are unusually numerous—seventeen on one sideand twenty on the other : evidently a terminal fringe. Imust remark that no species of Diaspis hitherto described hasless than five groups of spinnerets, except D. zamice, Morgan(Ent. Mo. Mag., Feb., 1890), which has none at all. Parla-toria appears to have always four. On the whole, I shallleave this insect at present in the genus Diaspis, subject tofuture correction.
