ON COPTOBEBA AND THE ALLIED GENERA. 
BT H. W. BATES, F.Z.S. 
In examining the species of Coptodera in my collection, I have 
md some features in their structure which seem to have escaped the 
•ention of all authors who have written upon that genus. These I 
w propose to make known, together with the descriptions of many 
w species. 
The genus belongs to the Truncatipennes division of the Oeodephaga 
id group PericalincB, distinguished from the Lehian<£ by the length of 
e labrum, which covers in great part the mandibles, and is often 
nger than broad, and by the simple penultimate joint of the tarsi. 
he species of Coptodera all live on and under the rotten bark of trees, 
mning with great rapidity ; their surface is free from pubescence and 
generally metallic in colours, and ornamented with flexuous bands of 
pallid hue. Their habit of searching for prey under close-fitting bark

mgthened mouth ; the mandibles being long, depressed, very acute 
nd scarcely curving towards the apex, and the ligula and paraglossae, 
•ogether with the labrum, lengthened and flattened in the same propor- 
,ion. The two terminal joints of the maxillary palpi form together an
