NEW PHYTOPHAGOUS COLEOPTERA 61 



the former rather strongly deflexed ; surface entirely impunctate, 

 fulvous; scutellum black; elytra convex, slightly widened behind, 

 very closely and finely punctured, the interstices equally finely 

 rugose , extreme apex smooth ; epipleurae distinct and continued 

 to the apex; legs fulvo-piceous , thp anterior ones generally 

 lighter fulvous; posterior tibiae with a distinct spine; prester- 

 num nearly invisible; anterior coxal cavities open. 



Australia, Somerset, January (L. M. D'Albertis). 



The shape of the thorax in this species differs rather from 

 most of the more typical forms contained in this genus, but in 

 other structural characters I cannot see sufficient differences to 

 ■justify the erection of another genus. 



56. Pliyllotreta iiijs'X'iconiis, n. sp. 



Elongate, slightly narrowed behind; below and the antennae 

 black ; above dark violaceous blue ; thorax finely punctured ; 

 elytra very closely semipunctate-striate, the interstices finely 

 longitudinally costate. 



Length 1 72"^ lines. 



Head impunctate with the exception of a few very fine 

 punctures above the antennae ; frontal tubercles obsolete but 

 the space between the antennae reduced to an acute narrow 

 ridge which joins the equally narrowed transverse clypeus ; 

 antennae half the length of the body, the first joint bluish 

 black; the two following ones more or less fulvous below, 

 the rest black; third joint slightly longer than the second, 

 fourth, one half longer than the proceeding; thorax transverse, 

 about twice as broad as long, the sides nearly straight narrowed 

 towards the apex , with a very narrow margin, anterior angles 

 obsoletely rounded, slightly oblique; surface finely but distinctly 

 punctured, the interstices somewhat rugose , near the base there 

 is an obsolete transverse depression more or less distinctly vi- 

 sible; posterior margin slightly sinuate in front of the median 

 lobe which is rounded ; scutellum as broad as long , its apex 

 broadly rounded, impunctate; elytra convex, nearly subcylin-
