232 NOTES ox .SOME AUSTRALIAN TEXEURIOMDAE, 



chrD^umeJoides Pasc. the liead is less coarsely rugose, the pronotum is minutely 

 ;iik1 lightly jjunctured and more nitid — the former rather strongly depressed be- 

 tween the eyes, the latter with only a taint depression near base to indicate the 

 medial channel, the foliate margins transversely rugose. Elytra with shoulders 

 obtuse, the sub-obsolete costae even less obvious, the disc much more finely punc- 

 tate, without anywhere a sign of linear arrangement. Dimensions: 15 >^ 10 mm. 



Rah. — Cooktown, Cairns, etc., N. Queensland. 



A species easily separated from O. chrijsomeluides by its lai-ger form, brighter 

 colour and much liner puncturation. 1 have O. chrysumehiides from Townsvillc 

 Brisbane and Tambourine Mountain, S. Queensland. 0. gihbus Blackb. from Cajie 

 I'ork is even more convex than major, is castaneous, not metallic, with black 

 markings, and coarse irregular punctures. The three species may be distinguished 

 as follow: — 

 1 — 3 Concolorous and metallic. 



2. Coppery bronze, pronotum closely and finely rugose. 



Hab. — S. Queensland f/irysotne/oides Pasc. 



paropsoides Cart. 



3. Castaneous bronze, pronotum very lightly punctate major, n.s,p. 



4. Xon-metallic castaneous with black maculae gibbus Blackb.

{a) C. acHtuiiguhis Bates = C. constrictus Cart. ='!. aeripennis Blackb., var. 



(b) C. aeneus Bates = C. coeruleo-niger Cart., var. A ^ C. macleayensis 

 Cart., var. B. 



(a) The first of these is certain by a comparison of specimens by ]\Ir. Blair. 

 I was misled by three inaccuracies in Bates's description. — (1) the colour is not 

 black, (2) there is a sulcus between margin and disc of prothorax, (3) tlie 

 liabitat is not Brisbane. In general C. aeripennis Blackb. differs from acutamju- 

 1ns Bates in the following respects, — hind angles of thorax less wide, narrower 

 sinuation, extreme border- thicker, with a characteristic carina at anterior angles, 

 luited l)y author. However, these differences are so modified in some examples 

 that it must be confessed that the distinctions are in some eases evanescent. I 

 rook a large number of acntangulus at Capertee, N.S.W., and some dozens of the 

 tvi^ical aeripennis at Mount Wilson, Blue Mountains. 



{h) These are well-marked colour variations in fresh exam)des, but I can 

 find no structural dift'erences whatever between tlie three. I found the first two. 

 aenetis and coeruleo-niger. in separate batches — never in company — some mile or 

 two apart at Bullahdelah, Port Stephens, while macleayensis occurs from the 

 Macleay River to Coraki on tlie Richmond. The typical aeneus has a blue-lilack 

 thorax, with lirassy elytra; coeruleo-niger is wliolly blue-lilack, while niacleayensis 

 is a bright brcmze, often with brassy gleam at .sides. The varietal names should be 

 retained. Four new species are described below. 



Adelium calosomoides Kirby =,1. bicolor Cart. (The latter is, I think, oiil,- 

 one of the many varieties of the former having red antennae.) 



Adelium angulatiim Blackb. My notes on this species* were based on <i mis- 

 named specimen ;.'ivcn me as angulatum by the late Canon Blackburn. This is 

 certainly angnlicoll? Casteln. The type of angulatnm. Mr. Blair writes, "is cer- 

 tainly not -1. angiilicolle Casteln. It resembles in thorax and elytra .1. scytali- 

 cum Pasc, and is, I think, tlie same species."
