diminishing wulk till it opens out at about two-fifths from 

 apex ; about base on each side of scutellar region with a feebly 

 raised space within the excavation : shoulders in the form of 

 strongly raised eqaulettes, projecting beyond each of which is 

 a membrane ; surface impunctate ; outer margins with strong 

 striae converging to subbasal notches. Pifgidium and propygi- 

 dium obsoletely reticulated. Under surface, and lega as de-

Hah. — Tasmania : near Hobart (A. M. Lea). 



In its shining elytra, which from some directions apjjear to 

 be quite glabrous, agrees with description of comata, but with 

 little else in common. The antennae on the type are completely 

 immersed within the prothoracic grooves, so that only the outer 

 side of the basal joint of each is visible, with the tip of the 

 club. The epaulettes are of the same shape and size as the 

 preceding species, and are similarly bounded, but they are 

 non-striated ; projecting beyond them also are similar golden 

 clothed memliranes. Many of its features exactly resemble 

 those of the preceding species. The type was obtained near 

 Brown's river under a stone which covered the nests of three 

 species of ants —

Black or almost so ; head, pronotum, apex of prosternum,

Head with shallow reticulate punctures. Antennae with basal 

 joint large, curved, of irregular shape, with a deep inner groove 

 and with punctures as on head ; club large, gently curved and 

 subcylindrical. ProtJwrax about once and one-half as wide as 

 long, disc moderately convex ; front margins narrowly raised 

 and divided into lobes, sides gently incurved to middle, but with 

 minute subgranular projections ; with uniform punctures as on

 basal impression, which on each side of scutellar region has a
