again as long ; the base and front margin are both bisinuate, the 

 former about a quarter as wide again as the latter; the sides 

 nearly straight, the sui'face very delicately wrinkled transversely 

 with a fairly well-marked longitudinal impression on either side at 

 the base. The puncturation of the elytra is very vague, and scale- 

 like in appearance, the transverse wrinkles are fairly well-defined 

 in front and at the sides. The spots of white pubescence on the 

 elytra resemble those of the preceding two species. The almost 

 flat, opaque, finely coriaceous head with distinct, not very close-set 

 punctures, and scarcely any trace of wrinkles, together with very 

 small size, narrow parallel form, and obscure color will dis- 

 tinguish this from all other species yet described of Cisseis. In 

 my opinion it, roseo-cujjrsa and some other species might well 

 form a new genus difiering from Cisseis in their short strongly 

 compressed tarsi, which approach those of Neos2oades, though the 

 claws and antennae resemble Cisseis. These insects seem to occupy 

 a doubtful position between Agrilidce and Trachydce.

Through the courtesy of the Hon. W. Macleay in examining a 

 series of Helceus from my collection and comparing them with his 

 types, as well as in furnishing me with types of several species 

 that were not represented in my collection, I am able to ofler 

 some notes on this genus, together with descriptions of several 

 new species, and to do so with some confidence that I mean l)y 

 the various specific names the same insects that are referred to 

 under those names in No. V. of the "Miscellanea Entomologica." 

 I do not consider it a certainty that in eveiy case Mf. Macleay 

 applies the names to the same insects that were before the original 

 describers, — nor does Mr. Macleay himself consider it so ; but as 

 there are so many of these of which the positive identification is 

 (either absolutely, or) at least to Australian students, impossible, I
