For LL ( smaragdvla ) " rygiclium" was evidently a mis- 

 take for "scutellum" ; the species in his collection, doubtfully 

 identified as smaragdula has the scutellum non-foveate, but 

 pygidium much as on pulchella (on p. 268 Burmeister was 

 given as the author instead of Boisduval). 



DlPHUCEPHALA PULCHELLA, Wateill. 



D. aziireipenuis, Macl. 

 This species varies in length from 6 to 8 mm., and has 

 an almost parallel range of variation in colour to that of 

 colaspidoides, from which species it may be readily dis- 

 tinguished by the much wider and less parallel-sided median 

 groove of the prothorax. From examination of the type of 

 azureipennis Blackburn considered that name to be synony- 

 mous, and * such was my own impression from a similar 

 examination. 



DlPHUCEPHALA NITIDICOLLIS, Macl. 



D. obscura, Macl. 

 This synonymy has been already noted by Blackburn r 

 and when I examined the specimens standing under the name 

 of obscura in the Macleay Museum they appeared to be simply 

 dirty ones of nit-idi colli*. 



DlPHUCEPHALA MINIMA, Macl. 



♦ The only specimen in the Museum that could be placed 

 in BBB, of Blackburn's table, is a small female that agrees 

 well with Macleay 's description of minima, except that the 

 front tibiae are bidentate (but the second tooth is very small) 

 and that the colour is purplish-blue instead of green (a com- 

 mon variation in colour). 



DlPHUCEPHALA HIRTIPENNIS, Macl. 



DlPHUCEPHALA COERULEA, Macl. 

 DlPHUCEPHALA LATIPENNIS, Macl. 



The types of these species were returned to the Queens- 

 land Museum by Macleay, and have perished. 



DlPHUCEPHALA HIRTIPES, 11. Sp. 



o . Bright metallic-green, densely clothed parts more 

 or less coppery; club of antennae, flanks of prosternum, hind 

 tibiae (except at base), hind tarsi, and parts of the others, 

 black or blackish ; rest of the legs and of the antennae 

 reddish. Head, pronctum (except a large medio-basal sub- 

 quadrate space), flanks of sterna and hind coxae with dense 

 depressed scales, more or less stramineous in colour, abdomen'
