402 DESCRiPTioxs or xew .species of avstraeiax cw.eoptera, 



equal, ami eaoli is iibout twice the lengtli ami twice tlie widtli ut tlie fifth. Tiie 

 elytra have a vague bluish gloss. 



COENOBIUS SPISSUS, 11. sp. 



S. — Black 111- hhickish; imizzle, five l>asal joints of antennae and legs (parts 

 of tarsi infuscatcd I more (jr less Mavous. TiKler surface and legs scarcely visil)ly 

 pubescent . 



Ileiul with rather coarse punctures. Eyes large and close together. An- 

 tennae moderately long. Protliorux at apex scarcely as wide as the median length, 

 a distinct oblique or slightly curved impression on each side of the base, in front 

 of which the surface is rather strongly gibbous; with rather coai-se punctures 

 throughout, dense in the middle, crowded on the sides. Elytra slightly longer 

 than wide; with rows of large punctures, in distinct striae througiiout. Length 

 {3, ?), 1.75—2 mm. 



?. — Diffei-s in being more robust, most of prothorax, elytra and under surface 

 pale, eyes more apart, antennpe and legs smaller, and abdomen with a large apical 

 fovea . 



Hab.—y.v\y S(mth Wales: Sydney (A. M. Lea). 



A small species very variable in its colours, but readily liistinguishcd from all 

 others of the genus by its dense and coarse jirothoracic ])unctures, and by the rows 

 of elytral punctures all being in distinct striae, of which the lateral ones, however, 

 are deeper than the others. There are seven males before me and six females; 

 of these the males scarcely differ in colour, except that the tip of tlie abdomen is 

 reddish on some specimens, but not on others; but no two females are exactly 

 alike, one is not much i)aler than the nudes, hut they usually have the prothorax 

 dull red, except for a narrow black basal margin, and elytra tiavous with the suture 

 and a variable extent of the base (on one specimen a narrow black basal margin 

 only) l)lack, the metastermim and middle (transversely) jiarts of abdomen are 

 more or less deeply infuscated, the rest of the under surface being flavous. On 

 most of the specimens the second joint of antennae is distinctly darker than the 

 first and third. 



CoEXOBius iN.sui,iroLA, n.sp. 



iS . — Black with a metallic gloss, more distinct on head and inothorax than 

 elsewhere; elytra piceous-brown, the tiyis paler, antennae (a variable number of 

 joints of the club infuscated) and leg's (femora more or less deeply infuscated) of 

 a rather dingy flavous or testaceous. Under surface and legs minutely pul)escent. 



Head with rather dense and sharply defined punctures. Eyes large and 

 close together. Protluirax about twice as wide as the median length, sides strongly 

 narrowed to apex, with a shallow oblique impression on each side directed to the 

 middle of the scutellar lol)c; ]iunitures dense and sharply defined, Init not very 

 large in middle, becoming coarse and crowded on sides. Elijlra briefly sub- 

 oblong; with rows of distinct ininctures in ratliei- narrow striae, Init on the sides 

 striae deeper and wider. Length (c?, 2). 12 — 2.?> mm. 



?. — Differs in being larger and more rolmst. nuuh paler, eyes more apart 

 (the distance between them almost c(|ual to the length of the liasal joint of an- 

 tennae), punctures smaller, antennae and h'gs shorter and abdomen more convex 

 and witji a large a|>ical fovea.
