836 CAUABIDiE FROM DORRIGO, N.S.W., 



differentiated by its less dark colour; elytra with li,«ht-coloured 

 margin; 9 with lateral interstices of elytra opaque; prothorax 

 wider, with basal angles less sharply marked, etc. L. minor is 

 very different, and may be distinguished from the other species I 

 liave examined bj its much shorter raetepisterna. 



Lecanomerus curtus, n.sp. 



Stout, oval; front shortly and obliquely bi-impressed; eyes close 

 to buccal fissure beneath; mandibles decussating; labial palpi 

 with penultimate joint bisetose in front; prothorax subquadrate, 

 much wider across base(l"75 mm.) than apex(l"2 mm.); elytra 

 ovate, lightly punctate-striate, interstices depressed, third unipunc- 

 tate about posterior third, striole at base of second wanting. 

 Black, nitid ((J and 9)j l^gs, antennae, palpi and labrum (also 

 abdomen) piceous-red; prothorax with a verj' narrow piceous-red 

 margin on sides posteriorly. 



Head short, stout(l -05 mm. across eyes). Prothorax broader 

 than long(l-2 x 1-8 mm.), broadest a little before middle, hardly 

 ■narrowed to base, lightl}^ and widely convex, subdepressed 

 towards base ; apex emarginate ; anterior angles obtuse but 

 marked; sides arcuate anteriorly; lightly and roundly narrowed 

 to apex, almost straight on posterior half; base truncate; basal 

 angles rectangular but obtuse at summit; lateral border narrow; 

 base impressed on each side; median line vex-y faint. Elytra 

 short(3-3 X 2-5 mm.) convex; base truncate, a little wider than 

 base of prothorax; basal border strongly developed, forming a 

 short decidedly dentiform prominence at humeral angles; apical 

 curve lightly sinuate on each side; lateral border narrow, reflexed; 

 striae lightly impressed (more strongly so on apical declivity), 

 formed of rows of closely placed punctures, sixth and seventh

Hab. — Dorrigo. 



A very distinct species, which can be compared only with L. 

 mastersi Macl., from which it differs conspicuously by facies;
