distinguished from most directions. Seen from behind the 

 greater portion of the head appears gently concave, owing to 

 the flattening of the middle parts and the slight elevation of 

 the sides of clypeus and front of labrum. The elytral striae 

 and punctures are confused about the tips, but regular 

 elsewhere. The three are (except for slight variations) 

 similarly coloured, so presumably are not immature ; the head 

 is more deeply infuscated than other parts, some of its margins 

 being blackish, the antennal club is also blackish; the 

 scutellum, suture, and sides of elytra, parts of sterna (some- 

 times the whole under-surface), and parts of legs are more 

 or less deeply infuscated, and there are two large but vague 

 discal blotches on the prothorax. 



Cheirrhamphica. 

 Blackburn proposed this genus for species possessing the 

 enormous front claws of the males of Cheiragra, but with the 

 others long and simple; in his table it was distinguished by 

 "basal four joints of front tarsi together shorter than apical 

 process of tibia," but this holds good only for the male; in the 

 female the joints of the front tarsi are longer and much 

 thinner, the fourth conspicuously passes the tibiae, and the 

 fifth is smaller with uniform claws. 



Cheirrhamphica pubescens, Blackb. 

 The common form of the male was the one described by 

 Blackburn, but the female is usually larger, and varies from 

 a form having the upper-surface entirely dark to one in which 

 it is entirely pale. The front tibial teeth are two in number, 

 acute and fairly long, characters sufficient to distinguish the 

 species from all the known Queensland members of the genus. 

 It may be taken in abundance, from flowering wattles, from 

 Geraldton to Beverley in Western Australia. 



Cheirrhamphica insularis, n. sp. 



Black; front femora and tibiae, and antennae, except 

 club, flavous. Upper-surface with numerous more or less 

 upright pale hairs or setae, parts of under-surface and of 

 legs with somewhat longer ones. 



Head smooth and with minute punctures about base, and 

 crowded, with some larger ones between eyes. Clypeus semi- 

 circular, with crowded punctures, its sides gently upturned; 

 labrum appearing as an upturned front margin to the clypeus. 

 Antennae eight-, club three -jointed, lamellae scarcely longer 

 than apical joint of palpi. Prothorax scarcely one-fourth 

 wider than its greatest length, sides evenly rounded, front 

 angles produced and acute, the hind ones gently rounded off; 

 punctures fairly dense and sharply defined. Scutellum with
