Lea — On Australian Coleoptera 303 



thin, but somewhat dilated to tips; tarsi four-jointed, third joint small, claws 

 simple. Wing's atrophied. 



Apparently an aberrant g'enns of the Endomyehidae (Leeonte records Alexia 

 as being' without tlie characteristic sculpture of th(> pronotum of that family) ; 

 at first glance the species described below appears to be a small erotylid, but the 

 tarsi are ti-uly tetramerous, the third joint (although larger than in most Austra- 

 lian g'enera of the Endomyehidae) being much smaller than the second, not hairy 

 and slightly produced under the base of the claw-joint. The prosternum is 

 ridged along the middle, and, when closely applied to the mesosternum, the ridge 

 appears to touch the intercoxal process of the latter; it really, however, does not 

 extend to 1ietween the middle of the front coxae. Closely emln-acing each hind 

 coxa there is. on the abdomen, a narrowly impressed line, but the space enclosed 

 could hardly be regarded as an abdominal plate, as in many of the Erotylidae. 

 Some specimens have thicker and longer legs and antennae than others, and these 

 are probably males, but there are apparently no distinct external indications of 

 sex. A second species, from Mount Tambourine, is in the Museum, but as it is 

 represented by an entirely pale (probably immature) specimen, it has not been 

 described. 



EROTENDOMYCHUS BIMACULATUS sp. nov. 



Plate iv, tig. 10. 



Eed or reddish-castaneous, most of pronotum and two large spots on elytra 

 l)]ack. Tipper-surface glabrous, nnder-snrface, legs and antennae minutely 

 pubescent. 



Head with minute punctures ; clypeus convex in middle, depressed on each 

 side. Antennae extending to about middle of metasternnm, first joint moderately 

 large, second-eighth about as long as wide, or slightly transverse, ninth larger and 

 more transverse, tenth still larger, eleventh slightly longer and Avider than tenth. 

 Prothorax almost twice as wide as long, sides gently incurved near base, hind 

 angles almost rectangular, the front ones rounded, apex gently ineurA^ed to middle, 

 base bisinuate ; with rather sparse and small but sharjily defined punctures, 

 becoming more numerous on sides and parts of base. Elytra at base slightly 

 wider than prothorax, Avidest at about basal third, thence evenly rounded to apex; 

 Avith roAvs of rather small ]iunctnres. TJnder-surface Avith sparse and minute 

 ]iunctures. Length, 2-75-3 mm.

A rather elongate-elliptic, flat species. On most of the specimens the pro-
