are not of much use. It is usually also necessary to state the 

 sexes of the specimens described, because the males are 

 frequently green, and the females golden, or brassy, or bronzy,, 

 and frequently with several joints of the antennae partly or 

 entirely dark, where on the males only the tip is dark ; they 

 frequently also differ in size. The sexes, in fact, are often so 

 dissimilar in appearance that, without the aid of specimens 

 taken in cop., it would be practically impossible to mate them. 



The presence of clothing on the upper-surface, or its com- 

 plete absence, was considered by Chapuis and Lefevre as of 

 more than generic importance ; but is sometimes only 

 of specific importance. Specimens also that are nor- 

 mally clothed on the upper-surface sometimes appear to be 

 glabrous through abrasion. In Edusa, although most species 

 are more or less densely clothed, several glabrous species 

 have been described. In that genus also the transverse 

 running together of the punctures (also treated as of more 

 than generic importance) is also of only specific importance. 

 In Rhyparida one species, quite normal otherwise, has long 

 hair on the upper-surface. On many of the species, otherwise 

 glabrous on the upper-surface, each angle of the prothorax has 

 a rather long hair, but these appear to be so easily abraded, 

 and are often so indistinct, unless specially searched for, that 

 I have usually omitted to mention them, even when noticing 

 their presence on the types. 



The majority of the species are metallic, frequently bril- 

 liantly so, and as with so many other metallic species, many 

 are extremely variable. On all of them the tips of the 

 mandibles and the eyes are black or blackish, and it was not 

 considered necessary to mention same, even when the species 

 are otherwise entirely pale. 



Of the genera recorded in Masters' Catalogue as Austra- 

 lian, iVod/«,(24) Dermorhytis,^'^^'' Eitmolphus,^'^^^ and Typo- 

 phorus,^^'^^ must be expunged, and probably Eurydemus^^^^ as 

 well. In the catalogue, 74 species are noted, to which 70 (29) 

 have since been added, bringing the number, after deducting 

 20 for previously unrecorded synonyms and varieties, to 124.

(27) T. australis is a Bhyparida. 



(28) E. grandis is probably not Australian.
