Their basal part is compressed (and wide on its broader face) 

 and becomes somewhat suddenly narrower a little before the 

 middle (more conspicuously in the front than in the hind 

 claws), but without the sharp distinction between the basal 

 and apical parts that constitutes true appendiculation. In 

 the strict sense, therefore, they must be called simple. 

 Anacheirotus was sufficiently discussed by me in a former 

 paper (loc. cit.J, and I need not repeat what I then wrote, 

 but it will be well to furnish a fresh tabular statement of 

 the characters distinctive of the Sericoid genera still remain- 

 ing for treatment in this revision, inasmuch as one of them 

 had not been discovered when my former tabulation was 

 written, and I have been able to identify in the Australian 

 Museum another genus (Odontofonyx j which in my former 

 revision I was obliged to pass over as unrecognizable. 



A. Claws (strictly rei^arded) simple ; mem- 

 branous wings aborted Callabouica. 



A A. Claws appendiculate or bifid. 



B. Body without membranous wings ... Pseudolieteronyx. 

 BB. Winged species. 



C. Antennae with only 7 joints Nepytis. 



CC. Antennae with more than 7 joints. 

 D. Anterior 4 tarsi of male strongly 



dilated Neoheteronyx. 



DD. Tarsi of male normal. 



E. Tarsi with a large membranous 



appendage at base of claAvs Odontotonyx. 

 EE. Tarsi not as E. 



F. P^orm strongly depressed ... Eurychelus. 

 FF. Form notably more convex. 

 G. Labrum extremely small 



and inconspicuous Anacheirotus. 



GG. Labrum strongly deve- 

 loped Heteronyx. 



The known species pertaining to the 8 genera tabulated 

 above are very unevenly distributed, the first 7 genera 

 together containing less than 12 species, while Htferonyo: is 

 of all the Australian LnmelUcornes the richest in known 

 species. 



Callabonica. 



The generic characters have been discussed above under 

 thei heading "Sericoides." I have not seen any additional 

 specimens referable to Callabonica since my original descrip- 

 tion was written. 



PSEUDOHETERONYX . 



I have two new species to be added to this genus. The 

 now known species may be distinguished as follows : — 

 A. Antennae of only 8 joints. 

 B. Elytra sparsely punctulate (about 

 12 punctures from suture reach 

 middle of width) baldiensis, Blackh.
