and epipleurae of elytra with large scattered punctures, the rest of underside 

 smooth except for the finely punctate apical segment of abdomen. Diimnsions: 

 10-11 X 4 mm. 



Ilab. — North Queensland: Ilerberton (H. J. Cai-ter). 



i took ten examples of this distinct species under dead boughs of Eiicalyptus 

 citriodora, sometimes in company with Adelium barbatum Cart., during my visit 

 in June, 1921. It is disting-uished by its combination of unusually nitid surface, 

 flat form and feebly raised elytral impressions, which, however, are wider than 

 the costifoi-m studs in S. repanda Pasc. and othere, occupying the whole width 

 of the interval. It belong's to the second group of my tabulation in which the 

 edge of pronotum is entire, and the disc contains lai'ge pmictures scattered 

 amongst the finer gTound punctures. The males are smaller and narrower than 

 the females and have the fore tarsi enlarged. Types in Coll. Carter. 



OiiOLirus OVATUS n.sp. (Text-tig. 14.) 



Text-fig. 14, 

 Omolipus ovaius, 



Elongate bi-ovate, the whole surface and appendages nitid dark blue, tai-si 

 rufo-tomentose beneath, apical joints of antennae sub-fuscous. 



Head minutely punctate, clypeal sutiu'e sinuous. Pro- 

 thorax convex, ovate, apex arcuate and gibbous in middle^ 

 base truncate, sides widely and evenly rounded, posterior 

 angles widely obtuse, surface polished and impunctate, the 

 narrow lateral margin unseen from above, basal margin 

 f oi-ming a, minute tooth at side. Scutellum ti'ansvei-se and 

 short. Elytra elongate obovate, suloate-punetate, each 

 with eight sulci, containing a chain of elongate, contiguous, 

 oval punctures that form crenulations on the sides of 

 sulci, the scutellary row represented by a single large 

 puncture, the naiTow horizontal margin more vaguely 

 crenidated by punctate impressions ; meso-sternum con- 

 cave and moderately long, minutely pmictate, abdomen 

 smooth. Dimensions : 11^-14 x 4 J-5^ mm. 



TlaS. — Mondrain Island, Reoherehe Group, S.W. Aust. 

 (Messrs. Grant and Wright). 

 Two examples are amongst the insects collected on the recent expedition 

 organized by Mr. H. L. White, led by Mr. Basset Hull. The smaller example is 

 labelled "no data," but is a fresh specimen differing only in size from the other. 

 The species is quite distinct by the following combination of chai-act«i-s : — elon- 

 gate bi-oval form, suleate elytra with its series of large elongate punctures, and 

 dark appendages. In my table (These Proc, 1915, p. 535) it should come 

 before 0. cyaneus Pasc. Types in Australian Museum, Sydney. 



CISTELIDAE.

Maxillary palpi long, apical joint subulate, mandibles simple, antennae rather 

 short, joints 1, 2, oval, (1 very tumid), 3 obconic, 4-10 cupuliform, of about 

 the same length as 3 but successively wider, 11 elongate ovate, considerably longer 

 (iban 10; aU joints bearing many short bristles and a few long setae. Eyes hemis- 

 pherical and prominent, entirely lateral (widely separated above and below in 

 both sexes); prothorax subcordate, at its widest wider than the head; truncate 

 at apex and base, lateral carina sub-obsolete (unseen from above) ; scutellum
