402 STUDIES IN AUSTRALIAN ENTOMOLOGY, XVI., 



(2 mm.), than apex(l*7 mm.), lightly rounded on sides, lightly 

 sinuate before base, basal angles subrectangular; elytra punctate- 

 striate, third interstice unipunctate about apical sixth. Pale 

 testaceous; head, pronotum, tarsi, antennae and palpi darker 

 than elytra; undersurface, legs and head on each side behind 

 eyes inf uscate; pronotum with a black vitta extending from apex 

 to base on each .side of disc; elytra with three black vitt8e, a 

 sutural one extending from scutelhim to apex on two inner 

 interstices of each elytron, and a lateral one on each elytron 

 extending from humeral angle to near apex on seventh inter- 

 stice, a transverse row of four black spots between apices of 

 each lateral vitta and the sutural vitta; abdomen with narrow 

 infuscate margin, apical ventral segment piceous-black; apex of 

 body infuscate, projecting beyond elytra. 



Head large(2'15 mm. across eyes), convex, lightly and obliquely 

 narrowed behind eyes to the broad neck; vertex minutely 

 punctate under a lens; front biimpressed on each side between 

 base of antenna and eye; eyes convex, prominent; postocular 

 part of orbits small, not protuberant, rising gently from neck. 

 Prothorax decidedly wider than head(2-5 x 2-5 mm.), lightly con- 

 vex on disc, widely margined laterally, Isevigate on disc, 

 punctate towards apex and base, and on sides outside the black 

 vittse; apex truncate; anterior angles obtuse, near neck; ba^e 

 with median part shortly but decidedly produced backwards; 

 basal angles rectangular, with summit obtuse; anterior marginal 

 seta at widest part a little before middle, not on border; median 

 line deeply impressed. Elytra subparallel(7 x 4 mm.), widest a 

 little behind middle; sides very lightly sinuate about anterior 

 fourth; humeral angles rounded; interstices nitid, hardly convex, 

 a row of minute punctures along middle of every one, first with a 

 punctate striole at base. Metasternum with a few fine setigerous 

 punctures near sides(only perceptible under a lens). Ventral 

 segments glabrous, bisetigerous, apical segment 2-punctate on 

 each side in $. Length 11-13, breadth 4 mm.
