Tyrt^osus mixtus, n. sp. 

 d- Dark reddish-brown, in places black or blackish; 

 antennae and tarsi reddish. Rather densely clothed with 

 somewhat fawn-coloured scales, almost uniform on under- 

 surface and legs, but variegated with white and sooty on 

 upper-surface ; elytral interstices with feeble rows of stout 

 scales. 



Head with dense and rather coarse punctures. Eyes 

 widely separated, a narrow depression behind each. Rostrum 

 rather short, wide, and feebly curved; with coars-e and dense 

 punctures partially concealed towa.-rds base. Antennae rather 

 short, inserted almost at exact middle of rostrum, Prothorax 

 slightly wider than long, sides strongly rounded ; with dense, 

 moderately large, round, deep, non-confluent punctures; 

 median carina absent. Elytra not much wider than pro- 

 thorax, long and parallel-sided to near apex, without sub- 

 humeral notches; with rows of fairly large, deep, oblong 

 punctures, becoming small posteriorly and somewhat rounded 

 on sides, interstices much wider than punctures, and each with 

 a more or less concealed row of granules. Metasternum with 

 a rather feeble ridge on each side between coxae; episterna 

 €ach with a continuous row of punctures, but becoming double 

 posteriorly. Abdomen with first segment not much longer 

 i;han second, depressed in middle, its apex rather strongly 

 incurved to middle ; third and fourth with dense squamiferous 

 punctures. Legs ^tout; femora strongly and acutely dentate ; 

 all tibiae bisinuate on lower-surface, and not dilated to apex. 

 Length, 5 J mm. 



9 . Differs in having the rostrum slightly longer and 

 thinner, with scales only at extreme base^ elsewhere shining 

 and with small but clearly-defined punctures, and basal seg- 

 ment of abdomen moderately convex. 



Hah. — Queensland: Mount Tambourine (H. J. Carter). 



Close to brevirostris, but with two conspicuous rows of 

 squamiferous punctures on the hind portion of the meta- 

 sternal episterna, and elytra with whitish scales in parts, and 

 without the preapical callus on each marked, although there 

 is a whitish spot immediately behind it on the male, but not 

 on the female. The sooty scales are distributed in irregular 

 spots and patches; on the elytra there is a vague whitish 

 fascia at the basal third, and remnants of another at summit 

 of the posterior declivity. 



Some specimens, from the Tweed River and Bundaberg, 

 indicate that this species is somewhat variable in size and 

 markings. They are all smaller (4-4J mm.) than the types, 

 and have the dark scales on the upper-surface forming four 

 or more spots on the prothorax, and three irregular mottlings
