Family Bombyliid.e. 



-A.nastcechus melanohalteralis, new species. Colorado, Buffalo, Platte can- 

 yon; August, 1906; a male and female specimen. Types in the collec- 

 tion of the University of Kansas. 

 The main reason for establishing this species in comparison with ni- 

 tidulus Fab. (= barbatus O. S.), depends on the enlarged black 

 tips of the halteres, which are scoop-shaped or rather obliquely flat- 

 tened, with edges incurved backward. Stalk of halteres yellow, 

 veins of wings mainly yellow. Aside from the larger size and darker 

 fuliginous wings, the structure and color of the halteres appear of 

 sufficient value to characterize a species distinct from nitidulus. Au- 

 thentic specimens of the latter exhibit yellow halteres with pale 

 knobs, which have an oblique shallow-pitted face directed backwards. 

 Length from front of eyes to tip of abdomen, 8 mm. ; wings are 

 slightly longer than body. 

 Anastoechus melanohalteralis, new species, fulvipennis, new variety. Same 

 locality and date as above; one male specimen. Type in collection of 

 the University of Kansas. 

 Apparently not different from typical melanohalteralis except in larger 

 size and color of wings, which are tinged with brown over half their 

 width anteriorly for two-thirds of their length; apex and posterior 

 margin subhyaline. Length from front of eyes to tip of abdomen, 10 

 mm.; wing, 11 mm.
