impression behind each e3^e, these not very close together. Ros- 

 trum i-ather short and wide, sides feebly incurved to middle; 

 basal half coarsely punctate and with a median ridge, apical half 

 shining and impunctate along middle, but with strong punctures 

 on the sides. Scape inserted two-fifths from apex of rostrum, 

 and shorter than funicle; 1st joint of funicle much stouter, but 

 scarcely longer than 2nd, the others transverse. Prolhorax 

 moderately transverse, sides rather strongly rounded; densely 

 and coarsely punctate; median carina feeble and continuous. 

 Elytra elongate, wider than and almost thrice the length of pro- 

 thorax; with series of large punctures; interstices regular and 

 narrower than punctures. Metasternal episterna with large but 

 not continuous punctures; 3rd and 4th abdominal segments each 

 with two irregular rows. Femora feebly dentate; tibiae curved at 

 base only. Length 4, rostrum 4; width 2 mm. 



Hah. — N.W. Australia (type in Macleay Mus.). 



Very close to j^f^'^'dalis, but the metasternum with three very 

 large punctures on each side close to the episternum. 



Tyrt^osus imitator, n.sp. 



Dark reddish -brown, elytra and antennae paler. Rather 

 sparsely clothed with ochreous scales, thin and subsetose on pro- 

 thorax, under surface and legs, but moderately stout on elytra. 

 Head and sides of base of rostrum feebly clothed. 



Head rather coarsely punctate, depressed behind each eye; with 

 a short median carina; eyes large and subapproximate. Rostrum 

 moderately long, sides incurved to middle, basal half strongly 

 punctate and with three feeble ridges, elsewhere shining and with 

 smaller but very distinct punctures. Scape inserted one-third 

 from apex of rostrum; 2nd joint of funicle slightly longer than 

 1st, none of the others transverse. Prothorax small, densely and 

 coarsely punctate; with a rather wide median carina. Elytra 

 wider than and more than thrice the length of prothorax; punc- 

 tate-striate, striae deep and punctures shallow (larger on sides 

 than elsewhere); the five sutural interstices each with a strong 

 row of punctures along its middle, the others with punctures on
