 Sydney district, Manly, Richmond River, Illawarra, 

 Caramba, Springwood. 



Pascoe's types are the sexes of the same species, these 

 differing in colour, and in the shape of the elytra, as in 

 /. biformis. The males are sometimes almost wholly black 

 (the ferruginous legs excepted), as in Pic's type of E. 

 rugosus, that of /. adusta and of another specimen sent 

 me by Mr. Carter having reddish-brown elytra as in the 

 female, which has the body entirely of that colour. The 

 elytra are narrowed from the base in the male, and broader 

 and subparallel in the female. Pic's description of the 

 tarsal claws is obviously due to an error of observation.* 

 The elytral sculpture is very coarse and suheon fluent. 

 The fifth ventral segment is angularly produced and ciliate 

 in the middle at the apex, and the penis-sheath long and 

 slender in the male. The intermediate tibiae are curved 

 and coarsely denticulate externally in both sexes. The 

 four females from Richmond River are larger and duller 

 than the rest, and have a broader head and a longer third 

 joint to the antennae: they may belong to a different 

 species. The length varies from 6^ — 13, and the breadth 

 from 2 (cy)-l (?) mm. K. mhi, ■■n,,,I,i, .Mac]., from (/aims 

 (length 31 lin.), may be a $ of /. adusta \ 



* The broad terminal tarsal joint mentioned by him must be the 

 lobed penultimate one.
