smaller (5 millim.), and with the band more diffused and distinct in the middle; both of 
these forms have often a bluish tint. The Chiriqui examples hardly exceed 4 millim., 
the band exactly as in the Guatemala ones. That these are simply forms of one species, 
I do not think any one who had seen a large series could doubt. It appears to be 
a common species. 
I do not at present adopt Spinola’s name, because it is quite uncertain whether his 
two insects are varieties of one species or whether they are either of them identical with 
any of the varieties alluded to above.

Only one of the three species described by M. Chevrolat can be retained in this 
genus. ‘The other two differ wholly in structure—S. rubripennis forming a new genus, 
which for convenience I place at present following this, and S. bicolor being referred to 
Colyphus.

One cf the most remarkable of M. Sallé’s discoveries, being very unlike any other 
Clerid known, and of doubtful location. It certainly, however, cannot come near 
Chariessa (as Chevrolat suggests), belonging as it does to the Clerides. The abdomen
