small) sharply-defined ones. Prothorax moderately trans- 

 verse, sides strongly rounded ; with dense, large, round, non- 

 confluent punctures; median carina not very strong, but trace- 

 able from base to apex. Elytra about one-third wider than 

 prothorax, sides parallel to near apex, subhumeral sinus 

 scarcely traceable ; with rows of large, deep punctures, becom- 

 ing smaller posteriorly. Mefasternum without an elevated 

 ridge on each side between coxae; punctures of episterna 

 interrupted. Abdomen with second segment almost as long 

 as third and fourth combined; these each with one row of 

 punctures across middle. Legs not very stout; femora rather 

 strongly grooved and feebly dentate, hind tibiae slightly 

 dilated at apex. Length, 4 J mm. 



Hah. — Queensland: Mount Tambourine (A. M. Lea). 

 Type, I. 1314. 



On the elytra there appear to be several irregular dark 

 patches, due partly to patches of sooty scales, and partly to 

 absence of paler ones. The scales more or less obscure the 

 sculpture, but the interstices are mostly wider than the seriate 

 punctures, and each appears to be supplied with a median 

 row of granules. A second specimen from Mount Tambourine 

 differs in being smaller (4^ mm.), the scales on the elytra 

 mostly sooty, the ochreous ones being distributed in irregular 

 transverse spots or fasciae, and a row of small granules on each 

 interstice is seen where the derm has been abraded. The 

 punctures on its head are somewhat smaller than on the type; 

 its abdomen is flattened in the middle of the first segment, 

 and on the type that segment is uniformly convex, but this 

 difference is probably sexual. 



Tyrt^osus foveiventris, n. sp. 



Black or blackish, antennae and tarsi reddish. Densely 

 clothed with sooty scales, interspersed with white ones. 



Head with dense but more or less concealed punctures. 

 Eyes separated almost the exact width of extreme base of 

 rostrum, a narrow but partially-concealed impression behind 

 each. Kostrum moderately long; basal third with coarse, 

 partially-concealed punctures, elsewhere with rather small but 

 clearly-defined ones. Prothorax small, about as long as wide, 

 sides strongly rounded; with large round punctures, very 

 close together, but nowhere confluent; median carina rather 

 feeble but traceable from base to apex. Elytra about one- 

 third wider than prothorax, base lightly trisinuate, sides 

 parallel to beyond the middle ; punctures and interstices 

 partially concealed. M eta sternum with the dividing lines 

 between the median and lateral portions very distinct, but 

 not marked by elevated ridges; punctures of episterna
