Examples with the pronotum bi-impressed on the disk are very- 

 distinct from the ones that are merely flattened, but the series con- 

 tains sufficient intermediates to indicate that they are all one species. 



This species has been taken from under bai-k of cedar and other 

 trees, flying at dusk, in a rotten branch of a large tree, in decaying 

 banana stalks, in dung, in rotting cocoa pods, under chips on stumps 

 of breadfruit tree, and in tunnels of Diatraea larvae in sugarcane.
