308 EE VISION OF THE GENUS NOTONOMUS, 



reaching base; lateral basal impressions deep, narrow, elongate. 

 Elytra oval (8x5 mm.) ; lateral apical sinuosities strongly 

 developed ; base narrow ; basal border joining lateral border 

 without any prominence at humeral angles; interstices strongly 

 and roundly convex, eighth about same width as ninth on basal 

 half; umbilicate punctures of ninth interstice large, interrupting 

 inner margin; lateral channel finely crenulate near inner side 

 along course of ninth stria ; lateral border widely reflexed. 

 Intercoxal declivity of prosternum rather narrow in middle, flat, 

 bordered on each side near peduncle; of mesosternum widely and 

 lightly concave. Length 14-15, breadth 4 '5-6 mm.

Elliptical-oval, depressed. Prothorax truncate-cordate; basal 

 angles rectangular; posterior marginal puncture at basal angle : 

 elytra decidedly sinuate on each side of apex, striate; interstices 

 lightly convex in ^, hardly convex in 9? third 3-punctate ; 

 humeral angles a little raised. Black, nitid; elytra steel blue; 

 legs piceous-black. 



Head convex, not large (2*6 mm. across eyes); front lightly 

 biimpressed ; eyes convex, prominent, lightly inclosed at base; 

 postocular part of orbits meeting head in a curve continuous with 

 that of the eyes. Prothorax broader than long (3-3 x 3*8 mm.), 

 depressed (especially towards base), a little wider at base 

 (2*8 mm.) than apex (2*6 mm.); sides lightly narrowed to apex, 

 gently narrowed to base, lightly sinuate before basal angles; base 

 lightly emarginate in middle ; basal angles strongly marked, 

 rectangular with summit obtuse; lateral border narrow anteriorly, 

 wider posteriorly, dilated at basal angles to receive posterior 

 marginal puncture; median line finely but rather deeply impressed,
