in the evening, and probably do not bite. Dr. Grabham says : " Collected with 

 Deinoccrites cancer, Theob., from crab holes along the sea shore. The water in 

 the holes is brackish. Larvs abundant after seasonal rains in May and October." 

 He says that the eggs are laid in rafts.

Dr. Grabham's figures and descriptions give the proportions of the air-tube of 

 the larva wrongly. We have been able to correct this matter from specimens 

 which Dr. Grabham has kindly sent us. The species is not allied to others that 

 inhabit crab-holes on other islands and on the mainland, and it would seem that 

 this species had independently acquired the habit on the island of Jamaica.
