634 STUDIES IN AUSTRALIAN ENTOMOLOGY, NO. XII., 



anterior angles obtuse, not marked; base truncate in middle; 

 basal angles roundly obtuse, not marked; lateral margins wide 

 and explanate, not reflexed; lateral basal impressions distinct, 

 wide, subrotundate; disc canaliculate, not declivous to middle of 

 base. Elytra ovate (4-2 x ^-T mm.), depressed; disc with a wide 

 lightly depressed space on each side about posterior third {extend- 

 ino- across 3rd, 4th and 5th interstices); apical curve oblique on 

 each side, apex itself obtuse; stria3 very lightly impressed, feebly 

 crenulate; interstices flat, 1st and 3rd united at apex, 8th much 

 wider than 9th on sides, narrow and rather convex near apex, 9th 

 seriate-punctate; lateral border narrow, reflexed. Tarsi with 4th 

 joint very small, a little emarginate at apex. Length 7, breadth 

 2-7 mm. 



Hab.—Q. : Mackay. (Given to me by Mr. C. French; Coll. 

 Sloane). 



F. queenslandicus has little aflinity to any previously described 

 Australian species. P. cooki, SI., is the only one from which it 

 is not at once differentiated by its small size; but it is not at all 

 closely allied to P. cooki, conspicuous differences being eyes far 

 less protuberant and not hemispherical; prothorax less trans- 

 verse, much less strongly narrowed to base; (the wide explanate 

 margins very diflerent from the narrower reflexed ones of P. 

 cooki); punctures of 3rd elytral interstice minute and punctiform 

 instead of large and foveiform. It seems more allied to P. papti- 

 ensis, SL, from New Guinea, of which I have no specimen for 

 reference, but is quite distinct by size smaller, colour not black, 



Genus Colpodes. 



In Masters' ' Catalogue ' and ' Supplement ' four species are 

 referred to Colpodes, but only one, C. mucro7iatus, Macl., properly 

 belongs to the genus. The others are («) Loxocrepis kigubris, 

 Motsch., dealt with above; (6) Dyscolus australis, Erichs., and 

 D. clilataius, which are not members of the tribe Platynini.^
