These are the most beautifully-shaped galls known to me, and 

 occur on a stunted sj^ecies of Eucalypts allied to Euc. uncinata 

 and Uiic. gracilis, but differing from either, and not agreeing 

 precisely with any described kind. The seed-vessels are mostly 

 prominently four-keeled, and the rather small flowers reddish 

 to crimson. Many of the galls are more or less abortive through 

 excessive attack of minute hymenopterous parasites, others 

 exhibit a large, more or less laterally placed hole, showing the 

 exit of some larger parasite, which had fed upon the inhabitant 

 itself. Associated with this species are found small, more or 

 less abortive galls of B. rechicfa (pi. iv., tig. '2h.) The specimen 

 shown at " a," and remarkable for its broad, clasping base, was 

 still green when picked, and the only one of this form met with. 



Brachyscelis calycina, spec, not: CPl. v., tig. la~d.) 

 Female gall. Solitary, rarely a few together, regular, cup- 

 shaped, sessile on the sides or ends of branchlets, obliquely erect ; 

 base broad, sometimes an incrassated ring, gradually dilated to 

 the irregularly dentated rim ; disk depressed, an elevated small 

 cone in the centre, exceeding the rim, and containing the minute 

 aperture. Exterior rough, dark-brown, disk blackish. Cavity 

 oval, channel moderately long, tubular. Insect not seen alive, in 

 dead specimens, fusiform, about half an inch long, pale ferru- 

 ginous, two last abdominal segments very slender ; tail bristles 

 black, nearly as long as the two last abdominal segments 

 together. 



Jfale gall. Almost cylindro-tubular, very slender, nearly 

 straiglit, pale-green, rim not dilated. Scattered alono- and 

 around very young twigs, never on leaves. 



Male. Female. 



Maximum length of gall ... 2 —3 mm. 15-25 mm. 

 Maximum diameter of base 0'7-l"0" 4- 8 " 



Maximum diameter of rim ... — 9-15 " 



Habitat. — ^Murray Bridge, Goolwa, Kangaroo Island. 

 These remarkable galls occur on stunted bushes of Eucalyptus 

 dumosa and E. oleosa. When young and still green and immature 

 they resemble the corresponding stage of some of the individuals 

 of the next species, but are never crowded. They are also found 

 occasionally much parasitised and abortive. 



Brachyscelis Neumaxni, spec. noc. (PI. v., tig. 2a-d.) 

 Female gall. Semi-erect, aggregated in dense clusters of many 

 individuals of both sexes, tiexuose-cylindrical, base surrounded b\- 

 a thicker ring, middle slightly bulging, slightly contracted ])elow 

 the rim, latter not much dilated, often divided into two parts Ijy 

 deep incisions, always irregularly dentate; disk slightly depressed^
