I am indebted to Mr. C. French for this fine species, which in 

 general appearance resembles i\^. variicollis, Chaud., but differs 

 by head larger and wider across occiput, ej^es less prominent, 

 postocular part of orbits longer and rising more gently from 

 head, eyes more distant from buccal fissure, the inter\ening 

 space more bulged; prothorax shorter, more strongly narrowed to 

 base ; border thicker and widened at basal angles to receive 

 posterior marginal puncture; elytra less convex, basal border not 

 raised above the lateral at point of junction, lateral apical sinuosi- 

 ties much weaker, ninth interstice narrower; intercoxal part of 

 prosternum strongly channelled, &lq. 



NOTONOMUS PLETCHERI, n.Sp. 



Robust, convex. Head large ; prothorax subcordate, with 

 posterior marginal puncture at basal angle: elytra oval, strongly 

 striate; interstices convex, third 3- or 4-punctate, tenth moderately 

 developed; humeral angles dentate. Upper surface rather metallic; 

 prothorax nitid, greenish, or of a beautiful coppery colour; head 

 of same colour as prothorax (but fainter); elytra greenish, often 

 flushed with a purple or cupreous tinge — ninth interstice and 

 margin usually a dark copper colour; under surface and legs 

 piceous-black. 



Head large (4-4-5 mm. across eyes); frontal impressions distinct; 

 eyes convex, rather prominent; postocular part of orbits large. 

 Prothorax broader than long (5 x 5*9 mm.), a little narrower at 

 base (3-9 mm.) than at apex (4 mm.) ; sides rounded, curving 

 gently to base without sinuosity; basal angles decidedly marked, 

 obtuse at summit; border wide, reflexed, thickened at basal angles 

 to receive posterior marginal puncture; median line deep; lateral 

 basal impressions deep, reaching base in full depth. Elytra 

 truncate-oval (11x6-8 mm.), convex, strongly rounded; lateral 

 apical sinuosities deep, wide; eighth interstice wider than ninth 

 on basal half; basal border strongly raised and obtusely dentate 

 at humeral angles. Intercoxal declivity of prosternum narrow 

 and rounded in middle; of mesosternum lightly concave. 9 with
