56 ISCHNOBAENA POLYMELA. 



pronotum. The anterior femora are 3| longer than the tibiae. 



Long. Corp. circa 34 mill. 



Sumatra (N. E.) : Tandjong Morawa, Serdang (Dr. B. 

 Hagen). 



Pleias, gen. no v. 



Ad sectionem Leistarcharia St§<li pertineus, Lutevae Dohrni 

 affinis, per tibiarum ac tarsorum anticorum longitudinem 

 proportionalem distinguendus. 



Closely allied to Luteva but much shorter in proportion and 

 the pronotum much shorter and broader. Segments of ros- 

 trum subequal (first very slightly shorter than second which 

 is slightly shorter than third). Eyes fairly large. Anterior 

 lobe of pronotum longer than posterior. Metasternum carinate 

 longitudinally. Anterior tibia and tarsus together subequal 

 to femur (femur 24, tibia 15, tarsus 10). Posterior femora 

 extending beyond apex of abdomen. Apical margins of 

 abdominal segments straight. 



Pleias Ritsemae, sp. nov. 



First segment of antennae 3} longer than pronotum and 

 I longer than second segment. Elytra extending beyond 

 apex of abdomen. 



Pale flavous, more or less infuscate above. Eyes blackish. 

 Legs fuscoflavous, intermediate and posterior femora apically 

 pallid ; posterior and intermediate tibiae pallid basally, and 

 more widely apically. 



Long. corp. 8-i mill. 



Sumatra (N. E.): Tandjong Morawa, Serdang (Dr. B. 

 Hagen). 



Luteva isadas, sp. nov. 



Apparently closely allied to concolor Dohrn, which I do not 

 know in nature and am therefore not able to give structural 

 diöerences as Dohrn's description is based upon colour ^). 



1) L. concolor was originally described from Celebes, a locality omitted by 

 Lethierry & Severin in their Catalogue, vol. III.
