﻿2A6 The entomologist. 



This species is probably sometimes mistaken for C. confuciana, 

 Thomson, which it resembles in colour and sculpture. But the 

 description of that species clearly refers to another Chinese form 

 in which the apex of the clypeus is reflexed and bifid. At least 

 this is the only way in which we can interpret the phrase " Caput 

 antice bituberculatum," as applied to a Cetonia. The C. confu- 

 ciana, Thorns., will therefore be a local form of C. submarmorea, 

 or a species closely allied to it, which belongs to a distinct group 

 distinguished by the gibbous apex of the pygidium in the male. 

 Among the more northerly species or races C. marmorata var. 

 cathaica comes nearest to C. insperata, Lewis, differing from it 

 chiefly in colour and size, and especially in its much broader 

 form. 



Cetonia submarmorea, Burmeister. 



Chia-ting Fu. 



A dark brassy green, and less closely punctured variety, re- 

 sembling therefore the above-described C. cathaica ; but the bifid 

 clypeus and the gibbous pygidium and scarcely depressed abdo- 

 men of the male leave us in no doubt that it belongs to the G. 

 submarmorea group. 



Cetonia viridi-opaca, Motschulsky. 

 Chia-ting Fu. A single example, agreeing in form and colour 

 with examples of Motschulsky's species from the Amur, but 

 differing somewhat in sculpture. C. viridi-opaca is known to 

 belong to a very variable series of the genus, the specific limits 

 of which have been subject to much discussion. 



Family LAMIIDiE. 



Lamiomimus gottschei, Kolbe, Archiv. fur Naturgesch. 1886, 

 p. 224, tab. xi. fig. 39. 

 Two examples from Ichang, differing in nothing, except the 

 darker (brassy blackish brown) ground colour, from those found 

 in Korea and the neighbourhood of Peking. 



Cyriocrates horsfieldii, Hope. 

 Ichang. One small example. 



Melanauster chinensis, Forster. 



Chia-ting Fu. 



Coscinesthes, nov. gen. 



A Monoharumid form, with a sharp and complete margin to the cicatrice 

 of the scape, rather narrowly divaricated tarsal claws, and simple outer edge 

 to the intermediate tibiae. These characters bring it into near relationship 

 with JEutceniojisis (Gahan), but the facies and other structural features are 

 very different. The head is rather narrow, the front parallel-sided, but the 

 antenniferous tubercles contiguous at the base and separated above by a 

 narrow cleft ; the lower lobe of the eyes narrow, and barely reaching half- 

 way to the base of the mandibles. The antennae ( 2 ?) are a little longer
