 tions contain mostly young specimens and larvae, which 

 only in a few cases can be identified as belonging to 

 definite genera.

Several well preserved and adult specimens belonging 

 to this species were taken. They are peculiar in pos- 

 sessing large orange-coloured pigment-spots, just as I 

 have previously observed in a living specimen.
