Dimensions — (J. 16 x 5 ram.; 2,16-5 x 5-6 mm. 



Hab. — Dorrigo, New South Wales. 



Six specimens, taken by the author, July, 1910; under bark of 

 rotting timber; also taken by Mr. Cox in the same district. 



Its nearest ally is A. heplegenoides Cart., from which it diflfers 

 in (1) smaller size, (2) lighter colour, (3) in the sinuate prothorax,. 

 and the absence of central impression thereon, inter alia. 



Types in author's Collection. 



Cardiothorax femoratus Bates, varr. stibdentatus Cart. — Mr. H- 

 W. Cox took a large number of specimens near Coff's Harbour, 

 which difiPer from the typical form in having a small but distinct 

 dentation of the hind angles of prothorax. There is, however, one 

 specimen, at least, amongst them, in which this small outwardly 

 directed tooth is absent; and I have, in my collection, a specimen 

 from Bellinger River, taken by Mr. Jackson, also of the typical 

 form (i.e., without any appearance of a tooth), so that it would 

 appear that this character is variable in this district. The 

 species is so strikingly diflferent, in its femoral characters, from 

 all other species; and the tooth is so small, that it does not seem 

 to me desirable to describe it as a distinct species. The absence 

 or presence of this tooth is certainly not a sexual character, since 

 both sexes of the typical form, and of the variety, are before me. 



Adelium 'porcalum Fabr., \'?lv. fulgens Cart. — Specimens taken 

 under bark of Eucalypts, near Bellingen, present a sti'iking 

 colour-variation from the normal type. This colour is a brilliant 

 violet-bronze, but darker specimens occurred amongst them. The 

 structural characters are normal.
