Australian Cistelidae. 89 



Dimensions. — 13-15 x 4-5 nam. 



Habitat. — Dorrigo, New South Wales (R. J. Tillyard), Dividing 

 Range, South Aus. (South Aus. Mus.). 



Four specimens (unfortunately all 2 ) examined are very distinct 

 from all known species. The prothorax is somewhat as in Allecula 

 planicoUis, Macl., on a larger scale. The combination of depressed 

 and parallel form, large seriate punctures and red appendages make 

 it readily recognisable. 



Type in the author's coll. $ wanting. 



Hybrenia pallida, n. sp. 



Elongate, elliptic, pale yellow, glabrous, prothorax, head and 

 underside a darker shade of yellow. Head- sparsely punctate, eves 

 very large and prominent, subapproximate (space between less than 

 | diameter of one), antennae long, joints -±-11 very gradually and 

 successively shorter than preceding. Prothorax subquadrate, 

 slightly wider than long, front angles widely rounded, posterior 

 rectangular, disc irregularly dotted with large round punctures 

 with a more or less laevigate medial line, and irregular laevigate 

 intervals elsewhere; base slightly sinuate and impressed near middle. 

 Scutellum triangular. Elytra not much wider than prothorax at 

 base, and four times as long, striate punctate, with a short scutel- 

 lary, and nine other rows of large, round, closely placed punctures, 

 becoming smaller towards apex; intervals smooth, except for a 

 few iregularly placed punctures of about the same size as those 

 in striae; underside coarsely and sparsely punctate, except on 

 apical segments of abdomen, fore tibiae swollen, posterior tibiae 

 flattened and curved, posterior tarsi with basal joint as long as the 

 rest combined. 



Dimensions. — 14-15 x 5 mm. 



Habitat. — C. York. North Australia. 



Two $ specimens examined, the type in the Brit. Mus. coll., and 

 a less perfect specimen in the Macleay Mus., Sydney. It may he 

 recognised by the colour, the somewhat vermiculate smooth spaces 

 on the pronotum, and tin- regular close punctures of elytral series, 

 with nitid but sparsely punctate intervals. //. vittata, Pasc, from 

 the same region, differs in colour, in its pubescence, closely punctate 

 pronotum, and elytral intervals, and smaller seriate punctures. 



Hybrenia femorata, n. sp. 



Elongate, ovate, nitid black, with sparse, short, brown pubescence, 

 tarsi castaneous beneath, femora with apical two-thirds pale yellow.
