Chaiiliodes a^id its Allies. 37 



Hermes costalis, Walker (of which Hermes anticus^ Walker, 

 is a ? ) is identical with Neuromus grandis^ Thunberg [Heme- 

 rohius grandis^ Thbg. Nov. Ins. Sp. pt. i. p. 28, fig. 44, from 

 Japan). The species varies considerably in the number of 

 pale spots ; and the Chinese examples show an approach to 

 my C. infectus from Darjeeling. 



Hermes dubitatus^ Walker (without locality), is not the ? of 

 ChauUodes californicus, as supposed by Hagen, in which he 

 was followed by me (Journ. Linn. Soc, Zool. vol. ix,), but is 

 identical with H. diver sus^'WaWer (New Zealand). The types 

 of diversus have the wings much crumpled, and I have only 

 recently seen perfect examples. 



Hei-mes maculifera^ Walker, appears to be only the ? of 

 ^naculijyennis, Gray, though the diiference of the localities 

 (Malabar and Java) would favour the suspicion of their being 

 distinct. 



ChauUodes dtsjunctus, Walker (in Lord's ' Naturalist in 

 Vancouver's Island and British Columbia ') , is a good species 

 of ChauUodes, and the largest yet known. I also possess it 

 from Vancouver's Island, but have only seen females. 



Hermes lO-macidatus and Hcorritj^)iens,^alker (Trans. Ent. 

 Soc. Lond. new series, vol. v.), are species oi Neuromus allied 

 to N. testaceus and N. hieyoglyphlcus. Corrlpiens is from 

 Brazil ; but there is no label to indicate the locality of 10- 

 maculatus.
