Gcodejjliagous Culeoptera of Juinin. 28* 
Nigerrimus, nititlus, antennis a]iice, palpis tavsisque piceo- 
rufis ; tliorace cordato iit in Ft. elongato, utrinque fovea 
lata rugoso-punctata, plica lateralis cum margine hand 
connata. 
Long. 6^—7 lin. $ ?. 
iS^agasaki. Also at Kiu-Kiang, on the Yang-tsze. 
Many examples. 
So closely allied to the South European Ft. elongatiis, 
that the differences in the form of the thorax seem to be 
the only distinguishing character. The general form is 
rnoderately elongate and parallel ; the head precisely 
similar. In the tliorax the size and lateral rounding is 
the same ; but the anal angle is strongly salient and shar]) 
at the tip, causing a sinuation before it of the lateral 
margin ; Avith this is associated a peculiarity in the fold 
■which bounds the large thoracic basal fovea} ; instead of 
blending with the lateral rim, it continues separate to the 
base. The elytra arc punctate-striate.

1863, p. 252. 
Kawachi ; Hiogo. Also south coast of Manchuria. 
Allied to the European Ft. niger, and still nearer to 
the Siberian Ft, Eschscholtzii.

examples.
