superne inciso ; elytris ovatis, abrupte truncatis, pedbus lon- 
gissimis. 
Obs. — It is difficult to describe the above insect accurately, from 
the refraction of the resin. It differs in many respects from any 
known genera ; and from the singular thorax, which appears as if 
it had been submitted to the knife of the anatomist, I have given it 
the name of Temnodcra. The thorax resembles closely the ball 
and socket.

Obs. — This remarkable insect is in Mr. Strong’s superb collec- 
tion. As it differs from all the Elateridce in the singular form of 
the thorax, I have given it the name of Mecynocanthus, from p.r\Kvvw, 
and cutavda, from its thoracic angles being produced into spines.

Caput rubrum, antennis pectinatis, atris. Thorax sanguineus, linea

Foemina adhuc latet ; forsitan ad genus Ctenicerum amandandus. 
Obs. — This insect approaches in its form E. melanocephalus, Fab. 
which is found on the Coromandel coast. I have no doubt that 
eventually it will be discovered in a recent state. A species, closely 
allied to it, found in Madagascar, is described by Dr. Klug.
