Edusites under the name Cleptor^ which, however, does not seem 

 to differ from Edusa by any very striking character. Apparently,. 

 Clejotor has the eyes entire (instead of " obsoletely sinuate 

 within"), the antennae shorter, with the apex thickened; the body 

 glabrous, the presternum transverse, the femora unarmed, and 

 the tibi^ longitudinally sulcate ; these are all the points of dif- 

 ference I can discover. I have not seen any species in which all 

 of them are to be found, but one or more characterise a good 

 many species which I cannot separate from Edusa, and I think 

 they are all discoverable in some or other of the series in my col- 

 lection. In 1889 I formed a new genus of Edusites under the 

 name Edusoides, distinguished by its tibia3 being produced 

 laterally at the apex into an elongate horizontal process in both 

 sexes ; I have seen no other species presenting any indication of 

 this character. 



My conclusion therefore is that I am unable to find any well- 

 marked and constant character (except in the case of Ediisoides) 

 by which to break up Edusa even into subgenera, and I accord- 

 ingly apply that name to all the Australian Eu.moljndce known to 

 me possessing the following characters in combination : — Pro- 

 sternal episterna convex in front, elytra transversely wrinkled at 

 the sides, tibiae not externally prolonged at the apex into a hori- 

 zontal process. The following characters in addition are present 

 in all the species known to me : — Tibia3 not emarginate externally 

 near the apex, anterior femora very rarely altogether simple, the 

 basal joint of at least the anterior tarsi dilated in the male, claws 

 divaricate and appendiculate, the sexes differing inter se in the 

 structure of the basal ventral segment. I may add that I think 

 a better anatomist than myself might probably discover generic 

 differences that I have not observed. 



The following is a tabulation of the new species described 

 below, together with such others of the Edusce as I have identi- 

 fied. I do not think that I have seen any of the species from 

 N.W. Australia which the Rev. H. Clark described, and the ab- 

 sence from his descriptions of reference to structural characters 

 renders it impracticable to place those species (without having 

 seen them) in a tabulation. A similar remark would apply to 

 the species described by Germar and Bohemann as having the 

 anterior femora unarmed ; I have not seen any of these three, 

 and the descriptions do not state whether the femora are angulate 

 or rounded beneath. There remain unknown to me besides the 

 above E. jmhernla, Bohem., from Sydney (which seems to be near 

 my E. hella, but to have the clypeus entirely testaceous, and the 

 antenna? shorter), and E. viridtcollis, Lef. (which appears to ])e a 

 large species witli dense pubescence, and the posterior tiljiiu of tlie 

 male incurved at the apex, characters I have not seen in combina- 

 tion).
