Chaudoir's opinion that S. esmeraldipennis is a synonym of S. 

 obesulns. Castelnau's statement, that the prothorax of S. 

 esmeraldipeimis is longer than that of his Feronia sajjhyrijiennis, 

 characterises this species and fixes its identity. 



I note it as diff'ering from S. obesulns by form narrower; pro- 

 thorax less transverse, less strongly rounded on sides, narrower 

 at apex and base; ajDexless emarginate; lateral border less widely 

 explanate on posterior half; elytra more nitid, more convex, more 

 strongly declivous on sides and apex; interstices more convex 

 posteriorly, particularly at beginning of apical declivity; 6th and 

 7th striie much more strongly impressed, more strongly punctate, 

 8th stria punctate between the ocellate punctures; lateral apical 

 sinuosities far more strongly developed. 



Sarticus dampikri, n.sp. 



$. Robust, oval, convex; prothorax lightly transverse, border 

 very wide and reflexed posteriorly; elytra oval; deeply and fully 

 crenulate-striate, interstices convex, 3rd 4-punctate. Black, 

 iridescent (with a rather virescent tinge). 



Head rather large (2-3 mm. across eyes), convex, smooth. Pro- 

 thorax transverse (3-2 x 3-65 mm.), Isevigate, convex, lightly 

 declivous to base; sides evenly rounded; apex truncate, finely and 

 continuously bordered; lateral border rather wide and reflexed 

 anteriorly, very wide and strongly reflexed posteriorly ; basal 

 iovese deep ; median line strongly impressed, punctiform at 

 posterior extremity. Elytra oval (7-7 x 4-8 mm.), convex; inner 

 humeral angle well marked; striae deep, strongly crenulate, seventh 

 well marked and strongly crenulate, third 4-punctate, the posterior 

 puncture on apical declivity; interstices convex, not depressed 

 posteriorly; lateral border strongly reflexed; lateral apical sinu- 

 osities strongly developed. Prosternum with a narrow entire 

 border along anterior margin. ]\Iesosternum with intercoxal 

 declivity almost vertical, lightly and widely concave, concavities 

 of episterna strongly punctate. Metasternal episterna punctu- 

 late. Ventral segments Isevigate, nitid; first punctulate; second 

 with two or three punctures near sides; 3rd impunctate; three
