Three specimens ''From onions, Tobago, W. I., June 4th, 1903;" 

 from decaying insects, Pernambuco, Brazil, February, 1883 (six 

 specimens); four specimens, ''Host, Hyphantria cunea, November 8, 

 1895" (diary date which refers to specimens of Phora venusta Coquil- 

 lett). Date on specimens which bear same diary number October, 

 19-28, 1895. One specimen Orlando, Florida (Chittenden); and 

 eight specimens from Baracoa, Cuba (A. Busck). This specific name 

 seems to have been like nigriceps the general repository of all uniden- 

 tifiable yellow Phoridse.
