Australian and Tasmanian Cryptocephalides. 445 



Hab. W. Australia: Swan River, Pinjarrah (A. M. 

 Lea). 



A pallid subopaque species not very close to any other 

 known to me. The tarsi are sometimes almost black, 

 the basal joints, however, are usually not so dark as the 

 apical. In one specimen the hind femora are infuscate. 

 The elytra, abdomen, pygidium and sides of prothorax are 

 usually paler than elsewhere. 



LOXOPLEURUS DISCONIGER, n. sp. 



(Plates XXIV, XXV, figs. 102, 152, 174.) 



$ . Short, moderately shining. Black ; sides and base of prothorax 

 widely reddish ; legs black or piceous, the coxse paler. 



Head densely and finely and very densely and extremely minutely 

 punctate. Antennae slightly shorter than body, second joint dis- 

 tinctly more than half the length of third, third very little longer 

 than fourth and distinctly shorter than fifth. Pmthorax densely 

 and moderately coarsely punctate ; disc rather strongly gibbous ; 

 oblique impressions very short ; margins narrow. Scidelhim elongate- 

 triangular, base notched. Elytra almost quadrate, subhumeral lobes 

 moderately large ; densely and moderately coarsely punctate through- 

 out, but punctures posteriorly becoming somewhat smaller and 

 subseriate in arrangement with irregularly elevated interstices. Apex 

 of prosternum very wide, triangularly prolonged in middle. Third 

 and fourth abdominal segments strongly incurved to with the fourth 

 just traceable across middle. 



Length 2 mm. 



?. Differs in having a wide pallid fascia just before the middle 

 of the elytra and interrupted at suture, and a large apical spot on 

 each quite close to the suture. Antennae shorter and thinner and 

 punctures smaller. Fovea large, decidedly encroaching upon fourth 

 segment and which, as in the male, is just traceable across the 

 middle. 



Length 2h mm. 



Hah. N. S. Wales : Sydney (R. J. Carter and 

 A. M. Lea); S. Australia (Macleay Museum). 



A small widely distributed and very aberrant species 

 with the sexes greatly differing in size and markings, 

 and the markings of both sexes variable to a certain 

 extent. The dark part of the prothorax appears some- 

 times almost as a semicircle (the convex side hindward), 

 sometimes as transversely suboblong; in both sexes it 

 extends to the extreme apex and is connected with the
