and pale haired on the apical fourth, the remaining segments 

 appear darker on account of being rather thickly black haired with 

 only a few light ones intermixed. On account of the color of the vestiture 

 mainly, the abdomen appears to be colored as follows : first and second 

 segments pale, third darker with a pale posterior margin, remaining 

 segments dark. 



Holotype female and a paratype female from Ecuador, 

 collected by Parish, in my collection. 



This insect may be readily distinguished from others of its 

 group by the dark brown marking on the first abdominal 

 segment beneath the scutellum. 



Scione aurulans Wiedemann. 



The genus Scione of Walker, often given as DicUsa of 

 Schiner, is characterized by hairy eyes and by the first and 

 fourth posterior cells of the wings being closed. About a dozen 

 species of rather small sized Pangoninae are included under it. 

 I found one species common in various localities in Central 

 America in March, 1906, and procured a long series of specimens. 

 W%h good material at hand, careful comparisons with descrip- 

 tions have been made and I am convinced that I have the species 

 which Wiedemann called Pangonia aurulans and which has 

 never been recognized since, and also that Pangonia rostrifera 

 Bellardi and Diclisa misera Osten Sacken, are synonyms. 



The species occurs over a w^de range for specimens are at 

 hand from Tabasco, Jalapa and other Mexican localities, from 

 various places in Guatemala and from San Pedro, Honduras. 

 Specimens vary somewhat in size and in length of proboscis, 

 but are very uniform otherwise. 



It is an annoying fly where it abounds. It appeared to keep 

 close to the ground and with its long proboscis had no trouble 

 biting through one's trousers. More than a score of specimens 

 were actually counted on my clothing at one time. 



TABANINAE. 



Tabanus punctipleura n. sp. 



A large robust species of nearly uniform purpHsh brown color; third 

 segment of the antenna with a long basal projection. A small conspic- 

 uous patch of intense black hairs somewhat more than a millimeter in 

 diameter on each pleura just beneath the attachment of the wing. Length 

 22 millimeters.
