sexstriatis; and this, together with the absence of any crenulation 

 in the stri*, differentiate it thoroughly fi-om the four species of 

 the genus noticed by Chaudoir. 



Note. — I have a second species of Anatriclus from Mulwala 

 which agrees with Chaudoir's brief description of A. australasicf, 

 and which I believe to be that species ; it differs from A. 

 sexstriatis by its slightly smaller size, the front with a fine but 

 distinct puncture on each side behind the angles of the clypeus, 

 the el^'tra with all the strias present and strongly crenulate, the 

 humeral angles subdentiform, the episterna of the metasternum 

 punctulate, &c. 



Tribe NOMIINI. 



Genus M e o N i s. 

 Meonis convexus, n.sp. 



Elongate, convex, robust, Ifevigate ; head narrowed behind 

 ej-es; mandibles long, porrect, a setigex'ous puncture at anterior 

 extremity of scrobe; prothorax pyriform, sides lightly sinuate 

 posteriorly, basal angles obtuse; elytra oval, deeply 4-striate on 

 each side of suture, fifth stria strongly impressed on apical 

 declivity; metasternal episterna (with epimera) wide, much longer 

 than broad. Black. 



Head strongly transversely impressed behind vertex; occiput 

 cylindrical; vertex convex; front and clypeus deeply and widely 

 biimpressed; the space between the frontal concavities convex; 

 eyes small, hemispherical, distant from buccal fissure Sinus of 

 mentum wide, truncate at bottom, oblique on sides. Labrum 

 deeply emarginate, a large setigerous puncture on each side of 

 emargination. Prothorax much wider than head, widest Ijefore 

 middle, as long as broad (3-8 x 3 8 mm ); sides rounded, narrowed 

 to base, lightly sinuate near base ; anterior margin truncate; 

 angles obtuse, very near head; base truncate, a little rounded 

 near each angle; lateral border thick, equal, lightly retlexed; 

 marginal channel strongly impressed; median line very strongly 

 impi'essed, sulciform, reaching base in full depth; lateral basal 

 impressions strongly impressed, elongate, wide; spaces between
