synonyms, so that P. Clotho, Sfal = 6rimnea, Marsh.; Iris, Chp. 

 = purpureo-viridis, Clk. ; polyglyp)ta, Germ. = intacta, Newm. 

 There are also 8 names which seem to appertain to varieties, as 

 follows : alternata, Germ., and picta, Chp., vars. of iiigerrima. 

 Germ.; fallax, Newm., var. of Morio, Fab.; Froggatti, Blackb., 

 var. of intacta, Newm. ; rubrosignata, Bohem., var. of beata, 

 Newm.; trivittata, Chp., and cequalis, Chp., vars. pf stygia, Chp.; 

 Sidneyensis, Fauv., var. of liturata, Marsh. Regarding one of 

 these determinations {cequalis) I am not very confident, as wiU 

 appear below under the heading " stygia." 



Thus, after the suppression of the names mentioned above, I 

 find that there are 39 names that seem to represent valid species 

 of this subgroup, 30 of which have been previously described^ 

 while 9 are described now for the first time. 



Of these 39 there are 3 that I have not seen, viz., conjw/ata, 

 Chp., (from S. Australia); octolineata, Gory (from N.S. Wales); 

 and tenebrosa, Chp., (from Queensland). Judging from the descrip- 

 tions I take them to be valid species, but the particulars given do 

 not allow me to place them in the following tabulation, which 

 relates to the 36 species known to me : — 



A. Prothoracic fovea; well defined and deep. 

 B. Seriate punctures of elytra quite fine, and 

 (at any rate near the suture) but little 

 distinct from the interstitial. 

 C. Upper surface of a decided bright 



metallic green colour purpureo-viridif, Clk. 



CC. Upper surface not bright metallic green. 

 D. Basal joint of anterior tarsi of $ wide 

 and with rounded sides. 

 E. Apical ventral segment of J with a 

 strong impression reaching half- 

 way to the base morio, Fab. 



EE. Apical ventral seg.nient of J im- 

 pressed (at most) at extreme 

 apex. 

 F. Lateral declivity of elytra not 

 with two elongate transverse 

 fovecB.
