Larva. Body smooth ; air-tube five times as long as wide 

 with many single stout hairs and a tuft of four at the base ; 

 a false pecten of about eight teeth at the middle. Comb of 

 eighth segment with about twelve very large spines in a single

We have only two females, bred from Bromeliacese in the 

 Lawa district, March, 1917. We place the species in Den- 

 dromyia because of. .its resemblance to Dendromyia smithii 

 Coq. and mataea D. & K. We do not generally describe fe- 

 males as types for new species in a difificult genus, but make 

 an exception with this species which has such a characteristic 

 larva.
