1262 NOTES ON AUSTRALIAN COLEOPTERA, 



Erichson are called Ajoate by their authors, and I am not aware on 

 what ground Mr. Masters has referred them to Rhizopertha. I 

 am myself the author of Apatodes. 



The four species of Sir W. Macleay are from Queensland, and 

 all appear to have strongly marked elytral sculpture differing 

 widely from that of any species known to me. A2mte coUaris, Er., 

 is described as a small species with the elytra retuse-truncate and 

 bidentate behind, and the prothorax of a bright red colour ; I 

 shall refer to it again below. A. obsijya, Germ., appears to be a 

 remarkable insect having opaque pilose elytra, and is one of the 

 few of Germar's Australian species not known to me. 



The following species are from S. Australia. 



The first of theui and A. collaris, Er., may, I think, be attribu- 

 ted to Apate. They present the following characters which are 

 almost identical with those attributed to Apafe by M. Lacordaire, 

 viz., — head invisible from above ; antennae of 10 joints, joints 1 

 and 2 being together about as long as 3-7 together, joints 8-10 

 serrated (8 and 9 transverse) together about equal to the pre- 

 ceding 7 together in length ; tarsi slender and elongated, joints 2 

 and 5 much longer than the rest; elytra retnse behind, variously 

 spined. The next two species may perhaps for the present stand 

 in the genus Xylopertha as characterized by M. Lacordaire, in 

 common with which they present the following characters, — head 

 invisible from above; antennae of 10 joints, 1 and 2 being to- 

 gether about as long as 3-7 together, joints 8-10 together consider- 

 ably longer than the preceding 7 together, 8 and 9 nearly as wide 

 as long, apical joint elongate-cylindric, nearly as long as the 

 preceding two together ; of the tarsi joint 5 is longest, 2 and 3 

 nearly equal and each a little shorter than 5, joints 1 and 4 short, 

 elytra behind simply retuse. The following characters are peculiar 

 and would perhaps justify a new generic name for the species 

 presenting them, — (a) posterior 4 tarsi strongly compressed, so 

 that viewed from above they appear excessively slender — almost 

 hair like, (b) sexual characters strongly defined, one sex (no doubt 

 the male) of at least one species having anterior tarsi clothed
