 granules the mesonotum and metanotum and all the abdominal segments

 more than three times as long as broad ; fore femora unarmed beneath,

Mr. Jennings found this species to dive fearlessly into the water in the 

 bromelias when disturbed, disappearing beneath the surface and remain- 

 ing submerged for some considerable time. A number of specimens 

 were seen but efforts to secure them proved unavailing.
