CASSIDIDES. 
CHIRIDA. 
This genus was founded by Dr. Chapuis (Gen. Col. xi. 405) for 
certain species attributed by Boheman to Coptocycla and which 
differ from Coptocycla in their claws being appendiculate instead 
of simple. Dr. Chapuis says that owing to the slight regard 
Boheman paid to the structure of the claws in his descriptions of 
Cassidide it is impossible to specify accurately which of his 
Coptocycle should enter this new genus ; the only species he (Dr. 
Chapuis) can answer for as members of Chirida are two from S. 
America. The following species from tropical Queensland agree 
sufficiently with Dr. Chapuis’ diagnosis to be at any rate pro- 
visionally placed in Chirida, although it is quite possible that if 
they could be compared with the American species on which the 
genus was founded it might appear necessary to found another 
distinct genus for these Australian forms. It may be noted that 
one of the species described below is so near (judging by the de- 
scription) to Coptocycla Holmgreni, Bohem. that although 
Boheman does not describe the claws of that insect it is almost
