strongly rounded sides ; with dense round punctures, larger 

 on sides and smaller about apex than elsewhere, nowhere 

 confluent; median carina strong. Elytra cordate; with rows 

 of large punctures in wide strise, becoming smaller posteriorly, 

 interstices much narrower than striae, each with an irregular 

 row of small punctures. M eta sternum with a conspicuous 

 oblique ridge on each side between coxae; punctures of 

 episterna rather strong but not continuous. Abdomen with 

 a single row of punctures across middle of each of the third 

 and fourth segments ; basal segment feebly depressed in 

 middle. Legs stout; femora strongly dentate; hind tibiae 

 strongly dilated to apex. Length, 6-7^ mm. 



9 . Differs in being stouter, rostrum somewhat longer 

 and thinner, with smaller punctures, less numerous towards 

 base, antennae inserted not quite so close to apex of rostrum, 

 legs slightly shorter and basal segment of abdomen gently 

 convex. 



Hab. — Queensland: Cairns district (E. Allen, F. P. 

 Dodd, H. Hacker, A. M. Lea). Type, I. 1301. 



An abundant species, close to microthorax, but elytra 

 more sparsely clothed and cephalic carina more feeble. On 

 microthorax the scales are so dense that the interspaces be- 

 tween the elytral costae are almost entirely covered, and on 

 each elytron there is a conspicuous oblique stripe of pale 

 scales, of which there is no indication whatever on the present 

 species. On that species also the spot on each side of the 

 prothorax is very faintly indicated, and would probably not 

 be noticed unless specially looked for; on the present species, 

 even with badly abraded specimens, the spots are usually very 

 distinct. 



Tyrt^osus majorinus, n. sp. 



(S . Jet-black, antennae and tarsi reddish. Prothorax 

 with long stramineous setae, nearly all directed towards 

 median carina, each side in front with a conspicuous spot of 

 pale scales. Elytra with sparse, fawn-coloured scales scat- 

 tered about, but with a spot of similar scales behind almost 

 every large puncture, with somewhat larger spots of whitish 

 scales irregularly scattered. Clothing of under-surface vary- 

 ing from white to black. 



Head with rather dense punctures; with a short distinct 

 medio-frontal carina; with a wide depression behind each 

 eye; these closer together than is usual. Rostrum moderately 

 long; basal half with dense and coarse punctures, somewhat 

 linear in arrangement, apical half with much smaller, but 

 clearly-defined, ones. Prothorax with strongly rounded 

 sides ; with large punctures, having a tendency to become
