so7ne Australian Curculionidse. 465 



Tyrtaosus melanterio/'des, sp. n. 



Black ; antennae and tarsi of a dingy red. Rather sparsely 

 clothed (denser on sterna and legs than elsewhere) with 

 dingy greyish and sooty scales. 



Head with coarse crowded punctures. Eyes separated 

 less than width of base of rostrum, a rather narrow and deep 

 but partially concealed depression behind each. Rostrum 

 moderately long ; basal third with coarse, partially con- 

 cealed punctuivs, elsewhere with smaller (but not very 

 small) sharply defined ones. Pmthorav moderately trans- 

 verse, sides strongly rounded, subapical constriction stronger 

 than usual ; with dense, large, round, non-confluent punc- 

 tures ; median carina distinct, but somewhat irregular in 

 middle. Elytra cordate, about one-fourth wider than pro- 

 thorax, subhumeral incurvature very feeble; with very 

 coarse sculpture. Metasternum with a strong ridge on each 

 side between coxse ; punctures of episterna interrupted. 

 Abdomen with dense and rather coarse punctures, not in 

 regular rows on third and fourth segments. Legs stout ; 

 femora moderately grooved and rather strongly dentate; 

 hind tibise strongly dilated to apex, the others lightly so. 



Length 7^-8 mm.

In general appearance strikingly like some of the larger 

 species of Melanterius (e. g., semiporcatus). On the basal 

 half of the elytra the punctures are unusually coarse, large, 

 and long, so that from base to middle there are only from 

 four to six in each row ; the interstices there are also much 

 narrower than the punctures, and on some specimens are 

 irregularly depressed between two of the punctures, so that 

 these appear to be semi-double. On the basal half also the 

 transverse ridges between the punctures are on a level with 

 the interstices, so that striae are really absent ; on the apical 

 half, however, the striation is distinct, and the punctures, 

 although large, are considerably smaller, and without a 

 semi-double appearance. The basal segment of the abdomen 

 is gently depressed in the middle in the male and very feebly 

 convex in the female ; otherwise the sexes are scarcely 

 distinct. 



Tyrteeosus albolineatus , sp. n. 



Black, in parts very obscurely diluted with red; antennae 

 and tarsi red. Prothorax with a dingy depressed scale in 

 each puncture, but with a feeble median line of whitish
