Each orbit with three strong bristles, the anterior two at middle 

 and almost at same height; palpi slightly broadened. Wing vena- 

 tion as in varia. 



Length, 3 mm. 



Type, Petropolis, Brazil (P. Borgmeier). 



Type.— Cat. No. 26700, U.S.N.M. 



CLASTOPTEROMYIA FLORIDANA, new species. 



Female. — Similar to inversa in color and habitus. Differs as 

 follows : Mesonotum with a rather indistinct central vitta and traces 

 of two similar vittae between this and lateral margins; mesonotal 

 setulae in front of dorsocentrals longer, finer, and less numerous than 

 in inversa; wings as in that species, the cross- veins more pronouncedly 

 clouded; comparative lengths of penultimate and ultimate sections 

 of fourth vein 9.5 : 15, in inversa about 10 : 20 ; outer cross- vein at 

 very little more than its own length from end of fifth vein. 



Length, 1.5 mm. 



Type, Fort Lauderdale, Fla., February 18, 1919 (A. Wetmore). 



Nothing is known of the habits of this species. 



Type.— Cat. No. 26699, U.S.N.M. 



CLASTOPTEROMYIA TRISETA, new species. 



Male. — Similar to inversa Walker in color and habitus. General 

 color pale brown, third antennal segment and palpi subfuscous, 

 thorax not vittate, abdomen dark brown, legs stramineous, wings 

 almost uniformly pale brown. 



Each orbit with three bristles, the upper reclinate and the pro- 

 clinate one equally long, the lower reclinate one situated about half 

 as far in front of proclinate one as the latter is in front of the 

 upper reclinate ; palpi rather longer than usual. Thorax similar to 

 that of inversa, but the prescutellar acrostichals are absent. Last 

 section of fourth vein as compared with preceding section 16: 10; 

 outer cross-vein at less than twice its own length from apex of fifth 

 vein; second section of costa twice as long as third. 



Length, 1.5 mm. 



Type, Higuito, San Mateo, Costa Rica (P. Schild).

DROSOPHILA SCHILDI, new species. 



Female. — Similar in general color and habitus to callipteia 

 Schiner. Differs in having the ocellar spot and the mark surround- 

 ing the vertical bristles on upper extremity of each orbit larger and 

 darker, the scutellum dark brown with gray pruniescent marks on 

 margin and on a small round one in center of disk; the tibiae with 

 a faint brown preapical mark which is absent in calliptera, and the 

 wings differently marked. In calliptera there are but three fuscous 

 spots between apices of first and second veins exclusive of the dark 

 mark on first, the third one covering apex of second vein, in schildi
