central cone scarcely raised above the outer margin, aperture 

 minute. Exterior reddish brown, somewhat glossy, striated 

 longitudinally and irregularly rugulose. Cavity elongate 

 cylindrical, base either semicircular or the lower part greatly 

 contra.cted ; apical channel short and more or less funnel-like. 

 Insect not observed. 



Male gall (?). Tubular to trumpet-shaped, apex much dilated, 

 rim dentate or lobate, recurved, with a small central cone ; inter- 

 mixed with the female galls in the same clusters. Insect not 

 known. 



Male. Female. 



Maximum length of gall ... ... 8 -25 mm. 18-30 mm. 



Maximum diameter at base ... I'O " 5-9 " 



Maximum diameter in the middle 1-5- 2 " 8-10 " 



Maximum diameter of the rim ... 3-5 " 9-11 " 



Habitat. — Murray Bridge. In large clusters on the erect or 

 suberect stout branchlets and twigs of Eucalyptus dumosa, 

 causing the death of the branch on which they are situated. The 

 species is named after my old friend Mr. J. G. Neumann, who 

 resides at the locality named, and has always assisted me and 

 other friends of natural history most disinterestedly in the pur- 

 suit of researches in his neighbourhood, and has also liberally 

 contributed to the collections of the S.A. Museum. 



BraChyscelis (?) Beyeri^, spec, not: (PI. v., fig. ?>a-f.) 



Female gall. Solitary, on the end of branchlets of Beyeria 

 opaca, rarely in pairs, oval, or sometimes subfusiform, composed 

 of the fused altered leaves ; apex slightly elongated, or chiefly 

 occupied by the comj)aratively large aperture. Exterior greenish 

 when alive, smooth, marked by the edges and midribs of the 

 leaves denoted by slight ridges. Cavity elongate ovate ; channel 

 short, large. Insects not known. 



Male galls. Several together along the branchlets below the 

 female galls, minute, tubular, curved. Insect not known. 



Male. Female. 



Length of gall ... ... 1-5-2 mm. 11-22 mm. 



Diameter of gall 0-5-1 -0 " 5-8 " 



Habitat. — Arclrosssan, Yorke's Peninsula. 



This species, if it be a true Brachyscdis, would be the first 

 instance of such occurring outside of the genus Eucalyptus, the 

 plant belonging to the Euphorbiaceae. On account of the 

 similarity of type form of the galls, I insert it here provision- 

 ally, as the insects are unknown. Their study will probably 

 necessitate its removal to a separate genus. The specimens from 

 which I have draw the figure Avere gathered by myself in 1885.
