The extraordinary little insect on which this genus 
is founded is unlike any other described species ; although 
having the facies, colours and punctuation of the Cldcenii. 
The niaxillfB are very remarkable ; projecting as very 
slender, straight shafts far beyond the tip of the long, 
straight, acute mandibles, and having a slender short hook 
at the end ; the inner side towards the apex armed with 
a few horny teeth, and the basal part setose as in other 
Carabidce. I am not sure that the palpiform exterior 
lobes of the maxillas are jointed ; they appear simple as in 
Callistus, and are a little longer than the blade of the 
maxilla, the tip of which they cover as a hood.

Long. 3i lin. $. 
Hong Kong ; two examples, kindly given me by Herr 
ISIess, of jMunich. 
The head is shining brassy-green, the thorax darker 
green, cupreous on the disk, the margins extremely fine. 
The eyes are very salient. The thorax is rounded off to 
the anterior angles, which are close to the sides of the 
neck ; behind it is less narroAved to the remarkable tooth- 
like lobe which forms the hind angle, and Avithin which 
the base is very deeply notched. The fiilvous spot near 
the shoidder occupies the deflexed margin and three mar- 
ginal interstices ; the posterior spot lies on interstices 4 — 
8, very short on 4, 5.
