apparent diameter of one, antennae long, joints sublinear, 3rd 

 little longer than 4. 4-7 equal, 8-11 successively shorter. Prothorax 

 at base a little wider than the length, sides parallel on basal half, 

 then areuately narrowed to apex; this considerably narrower than 

 base, narrowly margined at base and apex, medial line impressed 

 and terminating in a large basal foveate depression ; disc closely 

 and rather coarsely punctate. Scutellum transverse, widely 

 rounded behind. Elytra narrowly elliptic, slightly wider than 

 prothorax at base and three and a-half times as long, shoulders 

 rounded, apex finely pointed; striate punctate, seriate punctures 

 large and close, intervals convex and finely punctate; sternum 

 distinctly and closely, abdomen minutely and sparsely punctate, 

 mid-tibiae curved. Male without sexual characters, except the 

 extended quasi-sixth segment, with its small external forceps; pos- 

 terior intercoxal process rounded. 



Dimensions. — 10 x 3 mm. 



Habitat. — Sydney (the author). 



Four examples taken by the author are superficially like Chro- 

 momoea rufescens, Bates, but the following are amongst the many 

 structural differences: — (1) Long, linear joined antennae; (2) large 

 prominent eyes, width of head across eyes 2 mm., space between 

 .5 mm. ; (3) prothorax black, much wider at base than at apex, 

 apical half areuately narrowed; (4) widely rounded intercoxal 

 process. Types in author's coll. 



Tanychilus ruber, n. sp. 



Elongate, sharply ovate, the whole red except the eyes, tips of 

 mandibles, and apex of femora (sometimes) black. 



Haul elongate in front, closely punctate, the clypeus more 

 coarsely so than the forehead, and separated from it by an 

 arcuate depression; forehead wider ami natter between the eyes 

 than in T. splendens, Bless., space between eyes about two-thirds 

 of the diameter of one eye; last joint of maxillary palpi securiform, 

 of labial triangular; antennae with joints filiform and elongate, 

 2nd very short, 3 longer than 4, 4-11 successively and very gradu- 

 ally shorter than the preceding. Prothorax narrower than the head 

 and truncate at apex, feebly bisinuate at base, slightly areuately 

 widening from apex t.o base; sides not so much constricted and 

 rounded as in a typical Tanychilus. distinctly margined through- 

 out, but only basal and apical margins visible from above, closely 

 and distinctly punctate, with a defined medial line and large basal 

 fovcatv depression, and two narrow transverse foveae near basal
