134 Arthur M. Lea: 



of each segment. Legs rather long and thin. Length o^, to 

 apex of elytra 1 2-3 mm. 



Hab. — Victoria : Sea Lake and Birchip (J. C. Goudie), Geelong 

 (H. W. Davey). In nests of Iridomyrmex nitidus. 



All the other known species of the genus have several joints 

 of the antennae strongly transverse. The prothorax nonsetose 

 at the sides associates this species with termitophila, from which 

 it is i-eadily distinguished by its highly polished and consider- 

 ably flatter prothorax, with the elytra not channelled at the 

 sides and the antennae considerably longer. 



Dahra termitophila. Lea. 



There is a specimen from Hobart (the only Tasmanian ex- 

 ample before me) which I cannot distinguish from the types, 

 but it differs in being somewhat smaller (2J mm.) and slightly 

 narrower, with the antennae rather more inflated in the middle. 

 It may represent a variety, but it does not appear desirable to 

 name it as a variety without seeing additional specimens. 



The original specimens were from a nest of Coptotermes 

 raffrayi. 



Dahra termitopJiilu, Lea, var. virtoriensis, n.var. 



Messrs. J. C. Goudie and H. W. Davey have sent from Sea 

 Lake and Geelong numerous specimens of a species, which 

 appears too close to termitophila to be regarded as distinct, but 

 which differ from the types of that species in having the pro- 

 thorax slightly more convex, and with less channelled sides. In 

 the types of ttrniitophila the channel on each side is well 

 marked and continuous from apex to base, although narrowing 

 posteriorly ; as a consequence the margins appears to project 

 almost horizontally. In the present variety the channel on 

 each side usually does not extend more than two-thirds of the 

 way to the base, and on several specimens is confined to the 

 apical fourth or even less ; on one specimen, in fact, the channels 

 are absent ; as a consequence the margins, or the greater portion 

 of them, appear to project obliquely downwards. The Victorian 

 specimens were taken in the nests of Iridoiiiyrniex nitidus.
