as long; with a few submarginal punctures. Elytra parallel- 

 sided to near apex; with dense and small, but sharply denned 

 punctures. Length, 3 mm. 



Hah. — Northern Queensland (Blackburn's collection) . 

 Type (unique), I. 11859. 



In my table would be associated with H. fusiformis, from 

 which it differs in being smaller, legs entirely pale, antennae 

 with third to eighth joints decidedly transverse, and the 

 ninth larger and of different shape; it is also close to //. 

 insignicornis, but the seventh and eighth joints of antennae 

 are at least twice as wide as long, instead of slighty trans- 

 verse, the third joint also' is no larger than the second. 



Heteromastix longicornis, n. sp. Figs. 7, 8. 



d . Black and flavous. With dense, short pubescence. 



Head gently convex, with two feeble interocular impres- 

 sions. Antennae long and thin, fourth joint the length of 

 first, slightly longer than third, and twice the length 'of 

 second, the others somewhat longer, tenth and eleventh 

 distorted. Prothorax twice as wide as long, margined 

 throughout, the lateral margins slightly dilated and thickened 

 near apex; with fairly large, submarginal punctures. Elytra 

 long, thin, and almost parallel-sided to near apex ; with 

 dense and small punctures, many of which are sharply 

 defined, but others transversely confluent. Subapical segment 

 of abdomen triangularly notched in middle. Legs thin, but 

 not very long Length, 3'5 mm. 



Hah. — New South Wales: Dorrigo (W. Heron), Gosford 

 (H. J. Carter). Type, I. 11863. 



The antennae extend to the tips of the elytra, the 

 distortion of the apical joints is very different from, that of 

 all other known species, the tenth is distinctly longer than 

 the ninth and eleventh, and slightly thicker, from one 

 direction it appears somewhat lopsided and from another 

 sinuous, on top near the apex there is a shallow groove, as 

 if for the partial reception of the eleventh ; the latter is 

 slightly longer than the ninth and strongly curved at the 

 base. The pale parts are the head, prothorax, scutellum, 

 a small part of base of elytra, and the sides to near apex (but 

 the two colours not sharply limitejd), legs (parts of tarsi 

 infuscated), and basal joints of antennae. 



Two females, from Dorrigo, probably belong to this 

 species, they differ from the males in having the head black, 

 except for a variable portion of the muzzle, the scutellum 

 black, the black of the elytra advanced to the base, except 

 at the sides, where it is continued almost to the tips,
