Maechidius parvulus, Macl. 

 M. acutangulus, Waterh. 

 PI. xxxvii., figs. 95 and 148. 

 M. par vulus was passed over by Blackburn as being 

 unidentifiable from the description. 1 have, however, 

 examined the type, and it agrees" well with the specimen he 

 identified as acutangulus, and which agrees with the descrip- 

 tion, and also with a specimen sent by Mr. Arrow as such. 



Maechidius capitalis, Blackb. 

 The type of this species is a peculiarly robust convex 

 specimen, with the head much more sinuous on one side than 

 on the other; it is now in the British Museum. I have seen 

 nothing at all close to it, and think it should not have been 

 made into a type. 



Maechidius sordidus, Boi., var. 

 PI. xxxvii., fig. 96. 

 A Sydney specimen was standing, without comment, 

 with other specimens of sordidus in Blackburn's collection ; 

 but it differs from the typical form (as he identified it) in 

 being of a brighter colour, with the clothing brighter and 

 longer (quite conspicuously so, even to the naked eye, on the 

 head and prothorax). A similarly coloured and clothed 

 specimen (from Brisbane) was in his collection, and I have 

 seen others from Galston, Sydney, and Mittagong. In the 

 table these specimens would fall into the place assigned to 

 sordidus, and they appear to represent a variety only of that 

 species. 



Maechidius fissiceps, Macl. (pi. xxxvii., fig. 97). 



M. latus, Waterh. (pi. xxxvii., fig. 98). 



M. excisicollis, Blackb. (pi. xxxvii., fig. 99). 



M. caviceps, Blackb. (pi. xxxvii., fig. 100). 



M. crenaticollis, Blackb. (pi. xxxvii., fig. 101). 



M. tibialis, Blackb. (pi. xxxvii., figs. 102 and 149). 



M. ater, Waterh. (pi. xxxvii., fig. 103). 



M. rugosicollis, Macl. (pi. xxxvii., fig. 104). 



M. clypealis, Blackb. (pi. xxxvii., fig. 105). 



M. longitarsis, Waterh. (pi. xxxvii., figs. 106 and 150). 



M. spurius, Kirby (pi. xxxvii., fig. 107). 



Some outline details of these species are given for purposes 

 of comparison. 



Caulobius punctulatus, Blackb. 

 This species was named as from the type only, but there 

 was a specimen labelled as a co-type in Blackburn'^ collection 

 and from the original collector and locality.
