Australian and Tasmanian Cryptocephalides. 431 



LOXOPLEURUS PALLIDIPES, n. sp. 



? . Of a rather dark metallic green ; under-surface black with a 

 greenish gloss, appendages and mouth parts reddish-testaceous, apical 

 joint of antenn;ie infuscate. 



Head densely punctate and strigose at base and sides of eyes, 

 shining and feebly punctate elsewhere. Antennae thin, scarcely pass- 

 ing hind coxae, second joint half the length of third, third slightly 

 shorter than fiftli. Prothorax with sides densely and moderately 

 coarsely punctate, elsewhere with rather small pimctures ; oblique 

 impressions distinct and rather deep ; margins extremely narrow. 

 Scutellnm triangular, base entire. Elytra oblong, subhumeral lobes 

 rather large; densely and coarsely punctate, punctures subgeminate in 

 arrangement about middle, posteriorly becoming seriate with regu- 

 larly convex interstices. Under-surface densely punctate. Apex of 

 prosternum subtriangular. Fovea large slightly encroaching on 

 fourth segment. 



Length 3^ mm.

 Lea). 



In one of the two specimens before me the hind femora 

 are blackish. The reflexed margins of the prothorax are

In build and colour this species somewhat resembles the 

 one I have doubtfully identified as Lox. suhvirens, Chp., but 

 is at once to be distinguished from it by its pallid legs. 



LoXOPLEURUS LUGUBRIS, n. sp, 



(Plate XXV, fig. 182.) 



^ . Black, with or without a greenish gloss ; sides of prothorax 

 narrowly obscure red, the red sometimes occupying a fairly large 

 space at the posterior angles ; elytra dark metallic green (or blue) ; 

 legs testaceous, tarsi and apex of tibiae black or infuscate ; antennae 

 blackish, a varying number of the basal joints more or less red. 



Head densely but not very coarsely punctate, strigose at base and 

 sides of eyes. Antenna3 as long as body, second joint half the length 

 of third, third slightly shorter than fifth. Prothorax scarcely twice 

 as wide as long, rather strongly gibbous in front ; coarsely and very 

 densely punctate ; oblique impressions rather deep ; margins very 

 narrow. Scutellum triangular, base scarcely visibly notched. Elytra 

 briefly oblong, subhumeral lobes very small ; densely and rather 

 coarsely punctate throughout, but punctures rather sparser and with
