NEOTROPICAL STRATIOMYIDAE — JAMES 597 



Subfamily Clitellariinae 

 Genus DIAPHOROSTYLUS Kertesz 



DIAPHOROSTYLUS INTERRUPTUS, new species 



Differs from the three described species of this genus in that the 

 legs, with the exception of the three apical segments of tlie anterior 

 tarsi, are entirely yellow or white, without a trace of black or brown, 

 and that the brown of the wings is more dilute, by no means blackish 

 brown. As in ^.^avipes Kertesz, the hyaline band of the wing is inter- 

 rupted near the discal cell. 



Male. — Head black, white-haired, the front with some brownish 

 hair intermixed ; antemiae yellow, its style, however, white ; the style 

 about two-thirds as long as the annulated portion; the subterminal 

 bristle smaller than the terminal one. Facial projection acute. 

 Thorax black ; the pleura white-haired, the dorsum and scutellum with 

 appressed golden hair; broad apex of scutellum and spines yellow. 

 Abdomen bare, with only microscopic jjubescence on the disk, but 

 with longer blackish and white hairs intermixed on the sides. Legs, 

 including coxae and trochanters, yellow ; the apical three segments of 

 the anterior tarsi brownish; the tibiae constricted basally; the con- 

 stricted portions of the middle and hind tibiae whitish. Wings light 

 brown ; a hyaline band crosses the wing beyond the stigma, but this 

 is broadly interrupted beyond the apex of the discal cell, so that the 

 second posterior cell has only a small hyaline spot in it and the third 

 is broadly infumated basally. Halteres yellow. Length, 4-5 mm.

 its close relationship to Myxosargus indicates that it belongs m the 

 Stratiomyinae.
