Woll. The male of this is his Ectinohoplia variabilis and 

 E. hispidula is the female. 



His E. chrysura, " var. diabolica" is the female of that 

 species. 



H. maculata, Bates, is certainly not :i var. of H. aureola, 

 Pall., the pronotum (amongst other differences) being much 

 more transverse. 



Sericania leivisi, sp. n. 



Testacea, levitcr metallica, capite, pronoto (lateribus et ba«eos 

 medio exceptis), scutello suturaque elytrali fuscis, dypeo vcl 

 testaceo vel fusco, corpore supra omnino crebre punctate, elytria 

 sulcatis, clypeo piano, rugose punctato, sutura frontali arcuate 

 carinato. 



Long. 8-9 mm. ; lat. 4-5-5 mm. 



Hub. Japan : Yokohama, Chiuzenji, Nikko. 



Although very closely resembling the type species, S.fusco- 

 Uneata, Motsch., from Manchuria, the Japanese species is 

 distinct. A series of S. fuscolineata in the British Museum 

 show no marked variation, and the Japanese specimens 

 (except one unusually dark example) are all without the 

 characteristic longitudinal lines upou the elytra. They 

 differ also in the head, which is without the strong carina a 

 little before the front margin of the clypeus referred to by 

 Motschulsky, but has instead a carina upon the frontal 

 suture. In the male the fifth joint of the antennae has only 

 a very short lamellar prolongation. 



Gastroserica herzi, Heyd. 



Mr, Lewis has mentioned as a pale variety of S. higonia, 

 Lew., a specimen from Yuyama. It is actually a distinct 

 species intermediate between S. higonia and S. brevicornis. 

 and has been described by Heyden from Korea under the 

 name of Serica herzi. I have seen an example taken by 

 Leech at Gensan. In addition to its characteristic colora- 

 tion (pale clypeus, black forehead, bimaculate pronotum, and 

 dark suture and sides of the elytra), it is distinguished by 

 the entirely obsolete front angles of the prothorax, nearly 

 straight posterior lateral margins, and scutellum intermediate 

 in length. The antennae are almost as in S. brevia rnis, 

 having three long and one short lamella to the club of the 

 male, but the clypeus, which is emarginate in S. brevicornis, 

 has a straight margin in 8. herd. The three species just 

 mentioned belong, with others, to the genus Gastroserica 

 of Brenske.
