llohhptii Masteraii, MacJ^eay, KS82 = H. sidnotish, Mars. 18H0. 



1 have determined this synonymy on the authority ot' 

 one of Mr. Masters's specimens sent to me by Mr. OUiff. 

 ]\[acLeay, in his description of//. Mastersiij writes of the pygi- 

 diiim instead of tlie propygidium as being punctate. The 

 pygidium is smooth. 



Apobletes difficilis. 

 Apobletes Sem^feri, Lew. 1801 = Vhttysoma JiJicUe, Sch. 1889, 



Some of the species in the genus Apobletes are so simihir to 

 some of those in Platysoma in their general aspect that it is 

 not always easy to separate them. Herr Schmidt's trivial 

 name has precedence to mine ; but I think the species shouhl 

 be placed in Apobletes on account of the width of the pro- 

 sternum. 



Platysoma Gorhamiy Lew. 



This species was given to me as a capture made by 

 Dr. Livingston in Africa; but I have others taken in the 

 Philippine Islands by Dr. Semper, and it is evident the first 

 locality is an erroneous one. The species belongs to the 

 newly-made genus Platylister, a genus apparently confined to 

 the Oriental region, the Malayan Archipelago and the Pacific 

 Islands giving the gieater number ; but there are some in 

 India and in the countries cast of it. None are known west 

 of Bombay; and a single species in South Japan, P.pini, 

 Lew., seems to mark its eastern limit.

L. 5 mill. 



Oblong-oval, rather convex, black, shining ; tiic forehead 

 concave, stria bisinuous ; the thorax — anterior angles a little 

 depressed and well produced, stria laterally strong and nearly 

 straight, leaving a margin somewhat similar to that of Platy- 

 soma Confucii, Mars., but it is as wide again, behind the head 

 the stria is somewhat fine, and near the angles it runs clo.se 

 to the thoracic edge, but behind the neck it leaves rather a 

 wider margin than in Platysoma abruptum, Mars., and other 

 similar species ; the elytra — striae 1-2 complete and strong, 3 

 interrupted in the middle, 4 represented apically by two punc- 

 tures, 5 by one point, the sutural is very short, occupying a place
