608 STUDIES IX AUSTRALIAN ENTOMOLOGY, NO. XII., 



elytra \vith interstices not opaque and depressed in 9? sixth not 

 narrowed to base, ikc; — from. iV^. jy/arit;;ec<?*s, SI., (the nearest 

 allied species known to me) by smaller size; larger head; pro- 

 thorax proportionately wider, more strongly rounded on sides, 

 basal angles not rectangular. It must be allied to N. viridilim- 

 batus, Casteln., (of which I have not a specimen for comparison) 

 but has not a green margin, and the prothorax must be, propor- 

 tionately to its width, longer (it could not be taken to be "longer 

 than the breadth" — Macleay's description of JV. cyaneocinctus); 

 the 9 bas not the elytra opaque with interstices " not convex " 

 (Castelnau's description of Feronia viriditnaTijinata)', the third 

 and fifth elytral interstices are not "broader than the others" 

 (Castelnau's description of Feroida viridilimhata). 



XOTONOMUS CUPRICOLOR, n.sp. 



(J. Elongate-oval, subconvex; head rather large (3-8 mm. across 

 eyes); prothorax subcordate, hardly wider at base (3-8 mm.) than 

 at apex (3-7 mm.), posterior angles subrectangular, posterior 

 marginal puncture in lateral channel a little before basal angle; 

 elytra finely and lightly striate, interstices fiat, 3rd 5-punctate, 

 8th narrow, 10th long, extending forward beyond middle of 

 elytra. Intercoxal declivity of prosternum flat, of mesosternum 

 deeply concave. Upper surface aeneous, prothorax more cupreous 

 than el3^tra; under surface black; legs and palpi red; mentum, 

 mandibles, metathorax and posterior coxse piceous-red; antennae 

 reddish-piceous. 



Head smooth, wide and convex between eyes; front biimpressed, 

 the impressions arcuate, well marked; mandibles not long and 

 decussating; eyes prominent; postocular part of orbits two-thirds 

 the size of eyes, rising sharply from head. Prothorax broader 

 than long (4-6 x 5-4 mm.), widest before middle; sides strongly 

 rounded at widest part, gently and obliquely narrowed to base 

 without sinuosity; basal angles strongly marked, almost rectangu- 

 lar, obtuse at summit ; border wdde, narrower towards apex, 

 widely reflexed towards base ; lateral basal impressions long, 

 narrow, uniting with posterior extremity of lateral channel.
