Tlie form of tliis speeies is niove evenly elliptieal and 

 less oblong tlum that of 7'. motschuhkyi It is also at ouce to 

 be distinguished by tbe red bcad and by the absenco of the 

 spots on the thorax and by Ihe red epimera. and opisterna. The 

 • scutelknii is evidently punctured and is red in some exaniples. 

 Tlie punetuation of the metasternum and of the whole ander- 

 side is nnich closer and tiner. The tarsi of both tlie.se insects 

 are rather short and the joints preceeding the claw -Joint are 

 widened and spongy beneath, a charaeter which at once separates 

 them from typical Europaean Triplaces. The tibiae are very 

 feebly widened toward their apex and are rather deeply received 

 into the grooved femora. Many exaniples of this were also 

 taken by Mr. G. Le^Ais in Ceylon. 



Triplacidea sumatrensis n. sp. 



Breviter ovata, creberrinie subtilissinie punctata, lutea, an- 

 tennarum clava fusca, mesosterno plus minusve infuscato, meta- 

 sterni lateribus epinierisque punctatis, elytris et scutello nigris, 

 pinictato-striatis, interstitiis fere laevibus. Long. 4.5 niillini. 



Hab. Soekaranda, Liangagas. 



Extremely like T. singalensis. bat to be distinguished from 

 it by the almost smooth interstices of the elytra. The scutellum 

 is quite smooth, whereas in T. singalensis a few puiictures are 

 to be Seen. The puncturing nioreover of the sides of the meta- 

 sternum with its epimera is coarser. The antennae are also 

 stouter with more liead-like. intermediate joints and their elub 

 is not so laxly jointed. The coxal lines are distinct but short 

 and the mesosternum is iufuseate at least in one example, but 

 is usually yellow and the elytral epipleurae are inclined to be 

 yellowish, especially in the less matured individuals. 



Triplacidea haemorrhoa n. sp. 

 Oblongo-ovata, creberrime subtiliter punctata, ferruginca, 

 nitida, antennarum clava, pectore al)domineque in medio infuscatis.
