Hab. — Queensland: Coen River (H. Hacker's No. 536). 



The eleventh joint of antennae near the base has a strong curved spine 

 marking the end of a large excavation; the tenth joint is longer than the ninth 

 and eighth conibiued, and also has a large hollow; on one side of the ba.se it is 

 produced so a-s to embrace the ninth feebly ; from some directions it appears as 

 two conspicuous joints, and the antennae in consequence appear to be twelve- 

 jointed; from other directions the eleventh also appears to be obliquely divided 

 into two joints; in fact the two apical joints alter in appearance with every point 

 of view. 77. hicolor has all the joints thinner, and the ninth to eleventh very 

 different. 



Heteromastix cribripexnis, n. sp. 



c?. Black ; tips of elytra, part of under surface of muzzle, and trochanters 

 obscurely pale. With moderately dense, ashen pubescence. 



Head with vague inter-ocular impressions; with fairly distinct punctures in 

 front, but not sharply defined. Antennae long and thin, second joint not half 

 the length of third, sixth and seventh each about the length of eleventh, and 

 slightly longer than the intervening ones. Prothorax fully twice as wide as long, 

 margined throughout, sides strongly rounded in front and slightly narrower there 

 than at base; with submarginal punctures. Elytra thin, slightly wider near apex 

 than at base; with crowded and comparatively large, sharply defined punctures. 

 Subapical segment of abdomen deeply notched. Legs long and thin. Length (d", 

 S), 4.5--5 mm. 



2. Differs in having the head smaller, with less prominent eyes, legs and 

 antennae shorter, and subapical segment of abdomen straight at apex. 



Hab. — Tasmania: Waratah, Bumie (A. M. Lea). 



Close to H. tenuis, but elytra without purplish gloss, and (on four specimens) 

 tipped with obscure flavous, the sides near base of prothorax hardly notched 

 (there is a feeble incurvature there, but on the male of tenuis there is a small 

 triangular notch) ; the pubescence of the elytra is denser, shorter and paler, the 

 antennae are thinner, and the abdominal notch of the male is much longer; 

 from n. niger it is still more distinct. In my table {I.e., p. 131) it would be 

 placed with H. dolichocephalus, to which it is not at all close. On one male the 

 abdomen and femora are obscurely paler than the adjacent parts. A male variety 

 from Southport has a flavous, almost white, vitta from base to apex of each 

 elytron, near the side, but dilated so as to cover the entire apex for a short dis- 

 tance. 



Heteromastix megalops, n. sp. 



c?. Prothorax, scutellum and legs flavous, elsewhere more or less deeply in- 

 fuscated. With short, ashen pubescence. 



Head large, gently concave in front. Eyes unusually large and prominent. 

 Antennae long and thin, extending almost to tips of elytra. Prothorax more than 

 twice as wide as long, base and ajiex finely margined ; sides suddenly and strongly 

 dilated, or obtusely dentate, slightly nearer apex than base. Elytra parallel-sided 

 to near apex; with dense, and fine, rugiilose punctures. Lengih (c?, 9), 2.75-3 mm. 



?. Differs in having the head smaller, eyes smaller (but still of large size), 

 antennae much shorter, and in the abdomen. 



JJab. — Queensland: Cairns (E. Allen). 



The elytra of the type could not be regarded as black, they are of a dark 

 smoky-brown, similar in shade to most of the under surface (the tip of the
