an entirely different identification of perturbans. We accept the 

 name grayii for our larva tentatively (see remarks under the follow- 

 ing species). 



Wyeomyia ochrura, new species. Fig. 72. 



The air tube is pale, with concolorous tip, with coarse single hairs. 

 Pecten teeth of the comb of the eighth segment simple. Subventral 

 tuft of the anal segment, large and stellate; lateral hair single. Ab- 

 dominal hairs tufted. Mr. Busck collected the larva at San Domin- 

 go, in the leaf stalks of young palms ; it was named " Dendromyia sp." 

 by Mr. Coquillett. We have it also from Mr. Urich in Trinidad, 

 named " Phoniomyia longirostris Theob.'' and from Surgeon W. 

 Campbell in Dominica named "Wyeomyia grayii Theob." What it 

 would have been named the next time it occurred, we do not know, 

 as we propose to fix it now by a name of its own.

Described from Guiana. We have it from Mr. Busck's collecting 

 in Trinidad and San Domingo. The larvae occurred in the flower 

 sheaths of wild Canna, where there is very little water and that of a 

 slimy nature. There is but a narrow space between the sheath and 

 bud for the larvae to live in. The eggs are laid singly, but in large 

 numbers in the uppermost, just opening flower. They are elliptical 

 and black. We have nothing to urge against the determination, nor 

 in its favor either. The species is evidently a very specialized one.

Described from Brazil and recorded from Trinidad. Mr. Busck 

 got the larva in Tobago Island in the base of a leaf of Bromelia. Mr. 

 Urich has sent it to us from Trinidad. The air tube is stout, strong- 

 ly tapered outwardly, pale with single stout feathered hairs. The 

 anal segment has the subventral tuft short and stellate, the lateral
