are only 2 lines long. Intermediate examples have tlie 
two basal and several apical joints only tawny. I can see 
no other difference. 
S. chalceiis, n. sp. 
Supra viridi-reneus, antenuis basi, palpis, thoracis et 
clytrorum marginibus pedibusque flavo-testaceis ; oculis 
valde convexis ; thorace regulariter rotundato, foveis minute 
punctulatis. 
Long. 2:^—21 lin. $ j . 
One example, Hiogo. Taken by JMr. Lewis also at 
Kiu-Kiang, on the Yang-tsze, in China. 
Similar in general form to S. vcspertinus, but distin- 
guished from all the allied sijccies by its prominent eyes, 
rounded (almost circular) thorax and brassy-green colour. 
The antenna) are brown, except the two yellowish basal 
joints. The thoracic foveas are shallow and covered Avith 
a fine punctuation. The elytral interstices are plane ; the 
margins and the apex yellowish. Underneath pitchy.

^Nagasaki. Also at Kiu-Kiang, on the Yang-tsze ; 
Cochin China ; Bengal. 
I have not seen sjDCcimens from the locality whence 
AViedmann obtained the species, but as Japanese speci- 
mens do not differ from others from China and Saigon, 
I believe the species is the same. The pale spots of the 
elytra are somewhat variable ; the posterior discal one 
being absent in many cases. 
Platymctujius corrosus, n. sp.

sciu'us, subopacus, pilis brevibus fulvis dense vestitus,

Hiogo ; Xagasaki. Also on the Yang-tsze and at Foo- 
chow, in China. 
Resembles P. vcsiitus, a Senegal species, but it seems 
most closely allied to P. Tkunhergi (Qucnscl), a species
