Genus ACANTHACORYDALIS Weele 



ACANTHACORYDALIS ORIENTALIS McLachlan 



Two specimens from Kuanshien, Szechwan, 1,800 to 3,500 feet. I 

 have one from Ichang, Hupei. In all three the median pale stripe of 

 pronotum is nearly of the same width throughout, only a trifle wider in 

 anterior part, but not so much as in Van der Week's figure of A. kolbei 

 from Omei Shan, or so wide as his diagram of A. orientaUs from 

 McLachlan's photograph ; and the photograph does not show it so wide. 

 On the sides of these specimens are several elongate pale stripes, very 

 similar to Van der Weele's figure of A. holhei; moreover McLachlan 

 says "somewhat irregular longitudinal lines, forming ill-defined bands 

 on either side." Therefore I consider that A. kolbei is a synonym of 

 A. orientalis. McLachlan's type Avas from Chia-ting-Fu, western 

 China. 



Genus NEUROMUS Rambur 



NEUROMUS IGNOBILIS Navas 



Several from Shin Kai Si, Mount Omei, July; near Mount Wei, 

 July 24 to August 4, 2,000 to 8,000 feet. Described from Kuanshien. 

 Very little different from N. latratus McLachlan, wings more fulvous 

 than latratus^ and latter is often darker toward tip. 



NEUROMUS MCLACHLANI Weele 



One from Long Tsi Shien, Mount Omei, about 3,000 feet. Mount 

 Omei is the type locality. 



Genus PROTOHERMES Weele 



PROTOHERMES DAVIDI Weele 



Three from Szechwan, August 1928. It is the largest species in the 

 genus ; P. homi Navas is evidently the same form. 



PROTOHERMES FLAVIPENNIS Navas 



One from Pei Bay, June (Gaines Liu), Szechwan. 



PROTOHERMES COSTALIS Walker 



One from between Mount Omei and Mount Wa, July 24 to August 4, 

 2,000 to 8,000 feet. Described from North China, also known from 

 Formosa.
