■different shape and colour, and legs variegated; H. 

 tub ereulifr arts has head of different shape, elytra bicolorous 

 and legs flavous. On the type the pale parts of the legs are 

 the apical half of femora, front tibiae and tips of the 

 others, and basal joints of tarsi. 



Helcogaster laterofuscus, n. sp. 



cf . Head behind eyes, sides of prothorax, scutellum, 

 prosternum, inesosternum, abdomen, seven apical joints of 

 antennae, and parts of legs, black or blackish ; elsewhere 

 flavous. With sparse, dark hairs; and very sparse, whitish 

 pubescence. 



Head rather long, opaque, and densely punctate ; a 

 narrow curved impression on each side from near base of 

 eye to labrum, and a faint median line. Antennae moder- 

 ately long and obtusely serrated. Prothorax about as long 

 as wide, apex slightly wider than base, a shallow, open, sub- 

 basal depression; punctures fairly dense on sides, but sparse 

 in middle. Elytra moderately long, sides evenly dilated 

 posteriorly; punctures very minute and rugulose. Basal 

 joint of front tarsi lopsided, with a distinct black comb. 

 Length (d , 9), 3'25-5 mm. 



9 • Differs in being larger, head with less prominent 

 eyes, curved impressions shorter and less distinct, median 

 line scarcely traceable, less of the base dark, and front tarsi 

 •combless.

The sides of the prothorax are rather deeply infuscated, 

 for blackish, on each of the three specimens under examina- 

 tion, so the dark parts are evidently natural and not stains; 

 Tience in my table of the genus the species would be 

 associated with H. ohliquiceps, which has the elytra entirely 

 dark, head somewhat different, and antennae much shorter. 

 On the male the four hind femora are rather dark on the 

 basal half ; the front femora, the middle of the four hind 

 tibiae, and the apical tarsal joints, are slightly infuscated. 

 From in front the head of the male appears to have a shallow 

 semicircular impression, marking off a feebly bilobed inter- 

 ocular elevation. The Rockhampton female, probably a 

 "very old one, has the head and tibiae entirely pale. 



Helcogaster fasciatus, n. sp. 

 d" . Piceous-brown and flavous. With very sparse, 

 w^hite pubescence, and with a few dark hairs; a small fascicle 

 of dark hairs near each eye.
