wide, sides feebly dilated to base, with an irregular depres- 

 sion on each side behind middle; punctures much as on head. 

 Elytra fully twice the width of prothorax at base, sides 

 dilated to near apex ; punctures larger than on prothorax but 

 not quite so crowded. Four hind tibiae lightly denticulate. 

 Length, 9 mm. 



Hab. — Queensland: Cairns district (A. M. Lea). Type 

 (unique), I. 6684. 



A small species in general appearance fairly close to some 

 of the dark varieties of cyanea, but the male with the ninth 

 joint conspicuously produced to one side at apex (as on the 

 males of grandis, aeneoviolacea, and pulchrivarm) ; the abdo- 

 men is not longitudinally carinated. The prothorax is 

 considerably narrower than on any other species in the 

 Museum. 



ANTHICIDAE. 



Trichananca victoeiensis, Blackb. 

 Lemodes corticalis, Lea. 

 The genus Trichananca was referred by Blackburn (ante, 

 1891, p. 341) without expressed doubt to the Oedemeridae, 

 and compared with several genera of that family. Subse- 

 quently I named as Lemodes corticalis a species that still 

 later (I.e., 1899, p. 83) he called attention to as a synonym 

 of Trichananca victoriensis, but expressed doubts as to the 

 genus really belonging to the Oedemeridae. Blair has recently 

 transferred both Lemodes and Trichananca (as closely allied 

 genera) to the Anthicidae, and confirms my description of 

 the head as having a distinct neck; a statement Blackburn 

 called in question. 



Trichananca concolor, King (formerly Anthiats). 



This species is congeneric with the preceding one, from 

 which it differs in being somewhat narrower and more 

 cylindrical, antennae stouter, the apical joint shorter and 

 semidouble, prothorax more dilated in front and with denser 

 punctures, elytra with larger punctures in more regular rows, 

 but the punctures becoming much smaller and the rows almost 

 disappearing posteriorly. 



Trichananca pisoniae, n. sp. 



Flavous ; legs (knees and tarsi excepted) paler than 

 elsewhere, base of prothorax and elytra on suture about 

 summit of apical slope lightly infuscated. Clothed with short, 

 pale pubescence, and in addition with numerous erect, 

 dark hairs. 



Head rather convex, strongly narrowed behind eyes and 

 with a distinct neck; scarcely visibly punctate. Eyes large
