 penultimate joints widened. 



9. Broader and larger, the elytra (the suture excepted), palpi, 

 legs, and about joints 1-4 of the antennae, reddish-brown or testa- 

 ceous ; the eyes smaller ; the elytra subparallel in their basal half.

Not uncommon in the Sydney district, in August, 

 September, and October, to judge from the numerous 

 specimens captured there by Mr. H. J. Carter, Commander 

 J. J. Walker, and Mr. G. E. Bryant. In the series in the 

 Museum there is a pair still " in copula," and a male 

 received more than fifty years ago. This species is much 

 smaller than those named by Pascoe, and apparently un- 

 described. Egestria hirtipennis, and E. rubicunda, Macl., 

 are of about the same size as I. biformis, and dark brown 

 in colour; but they could not be females of the present 

 insect, as they are each described as having an elongate 

 apical joint to the antennae. 



5. Ictistygna hirtipennis. 



Egestria hirtipennis, Macl., Proc. Linn. Soc. N.S.W. (2) ii, 

 p. 322 (1888). 

 " Very dark brown, subnitid, very roughly punctured and clothed 

 with soft, erect, cinereous hairs. Head square; eyes prominent; 

 labrum very short; antennae slender, last joint longer than the 

 others; maxillary palpi long, joints triangular with apical angles 

 inwards, last joint longer. Neck narrow, well defined. Thorax 

 transverse, rounded at anterior angles, truncate behind. Elytra 

 broader than thorax, more than three times its length. Base of 

 thighs, tibiae, tarsi, and palpi yellow. Length 2 tin." 



Hab. Queensland, Russell River, in the Cairns district. 



Evidently an Ictistygna (9), to judge from the descrip- 

 tion, but apparently not represented in the material 

 before me. The specimens from Sydney (<$ $) sent me by 

 Mr. H. J. Carter under the name E. hirtipennis are refer- 

 able to /. biformis. The much smaller size separates 

 E. hirtipennis from /. adusta. 



6. Ictistygna laticollis, n. sp. 

 Elongate, robust, the elytra somewhat shining; clothed with 

 long, soft, erect, brownish and cinereous hairs intermixed with
