with IVIr. AValker's description, and is, I believe, the only species of

!). Halticella lon^icoriiis n. sp.— 9. Length .16 inch. Black, coarsely 

 but not conflueiitly luuictured ;ind covered with a sparse wliite pile, this is fine 

 and denser on the swollen femora and tibia. Tlie antenniE is unusually long and 

 slender, subclavate ; the scape and legs are rufous, excepting the apical half of 

 the swollen femora, which is black. The abdomen is shining black with whitish 

 pile on the segments laterally ; wings dusky hyaline. 



Described from one sj)ecimen caj)tured at large. 

 This s|)ecies is near H. oiudas, but the difference in the antennae 

 and the apical half of posterior femora easily distinguish it.
