Macleay calls "Section II" of Liparetrus, and in that case I am 

 not at all sure that it would not be justifiable to retain the name 

 Automolus and regard Macleay's " Section II " as forming a dis- 

 tinct genus. But in this uncertainty I must pass the genus by 

 with the remark that it is certainly very closely allied to 

 Liparetrus. 



2. Microthopus. This is another genus (from W. Australia) 

 which Burmeister characterises as closely allied to Liparetrus. If 

 its author is right in saying that it is founded on a male example 

 it is unknown to me. If he was mistaken about its sex I should 

 regard it as possibly identical with my genus Macleay ia (in which 

 case my name would lapse). Here again I must pass the genus 

 by as uncertain. 



3. Homo! otr opus. This genus was founded by Sir W. Macleay 

 (Tr. Ent. Soc, N.S.W., II., p. 193) on an insect that I am unable 

 to identify. Apart from the antennse I find no character in the 

 diagnosis that seems really generic, and the antennal characters 

 alone do not appear to me conclusive. Nevertheless, from the 

 description of the species, I take it that the genus is likely to be 

 a good one, but there is no character mentioned by the author 

 that enables me to jjlace it in a tabulation. Moreover as Sir W. 

 Macleay asserts that the position of Homolotrojms is near 

 Xylonychus (which Lacordaire places among the true Melolonthides, 

 where I think it is certainly more at home than in the Sericoides) 

 it is quite possibly not a member of the sericoid group. 



4. Odontonyx. Another of Sir W. Macleay's genera concern- 

 ing which I cannot speak positively. The diagnosis would fit 

 Eurychelus but in the description of the species the author states 

 that there " seems to be " a kind of membranous appendage 

 beneath the last joint of the tarsi, and this remark I am afraid 

 compels me to pass the genus by, with the observation that it is 

 probably near Eurychelus. 



To the above I have to add nine new genera bringing up the 

 total number to 33. 



A. Prosternal sutures normal. 

 B. The claws simple (disregarding membranous appendages). 

 C. Winged species. 

 D. Femora glabrous and very slender and elon- 

 gate ... ... ... .. ... Telura. 



DD. Femora shorter and stouter and more or 

 less pilose. 

 E. Elytra very short exposing much of the 

 propygidium (all small species). 

 F. Clypeus margined in front. 

 G. Antennal club 3- jointed in both sexes ... Liparetrun. 



GG. Antennal club 5-jointed in the male ... Machayia. 



FF. Clypeus not margined in front ... ... Comophorus, 



EE. Elytra of normal length (except in a very few 

 large species).
