440 STUDIES IN AUSTRALIAN ENTOMOLOGY, xvil., 



Stichonotus piceus, n sp. 



(J. Oval, convex. Piceous; lateral margins of prothorax (widely 

 at base) and elytra (narrowly), first interstice, and legs reddish. 



Head large (1-6 mm. across eyes), deeply set in prothorax. 

 Prothorax transverse (1*6 x 3"3 mm.), widest at base, strongly 

 narrowed to apex (1-8 mm.), lightly bifoveate near base; sides 

 lightly rounded; apex widely emarginate; anterior angles pointed, 

 strongly advanced; basal angles sharply triangular; border nar- 

 row and equal on sides, very narrow and entire along anterior 

 margin, obsolete on base; median line lightly impressed. Elytra 

 wide, short (4-5 X 3-4 mm.), convex, lightly depressed on disc 

 behind scutellum ; striae entire, lightly impressed, especially 

 towards apex, subcrenulate, second (counting at base) obsolete 

 on apical declivity;* interstices hardly convex on disc, depressed 

 on apical declivity, ninth (counting at apex) narrow, not crenu- 

 late, seriate-punctate (punctures wide apart in middle); marginal 

 channel simple. Length 6-2, breadth 3-4 mm. 



ZTa^.— Tasmania : Mount Wellington (Lea; unique). 



Allied to S. leai SI., but differing by size larger, colour different, 

 striae of elytra decidedly shallower, interstices not convex. From 

 S. limhatus SI., it differs by colour, elytra far less strongly striate, 

 striae far less strongly crenulate, lateral channel simple, etc. 



Stichonotus limbatus, n.sp. 



$. Oval, robust; elytra strongly striate. Piceous, prothorax 

 and elytra with testaceous margins; elytra with first interstice 

 piceous to apex, interstices 1-7 piceous on at least basal two- 

 thirds, legs piceous-red, antennae and palpi testaceous. 



Head large (1-6 mm. across eyes). Prothorax transverse (1"6 

 X 2'95mm.), widest at base, strongly narrowed to apex (1-7 mm.), 

 lightly convex; sides narrowly angustate to anterior angles, sub- 

 parallel to base ; apex widely emarginate-truncate ; anterior 

 angles prominent, pointed ; basal angles triangular, slightly 



* I take the present opportunity to direct attention to an error in my 

 description of S. leai (These Proceedings, 1910, p. 380), where the second 

 stria is said to be "obsolete on basal declivity"; this should read, apical 

 declivity.
