joints long, subequal, fourth much shorter, fifth as long as third, slender; legs 

 pale, especially the femora, darker on tarsi, spurs nearly black. Wings faintly 

 brown, with few brown hairs; venation much as in C. bidens, but the radial 

 sector near base of discal cell is more strongly bent and in a longer curve; 

 the median cell is longer than discal, and the first fork is broad at base on discal 

 cell. In the hind wings the discal cell is much more slender than in C. bidens, 

 and the first and second forks reach back' farther on the cell. In the female 

 the seventh ventral segment is slightly prolonged in the middle. 

 Expanse 8 mm. 



CHIMARRHA PERSIMILIS, sp. nov. 

 TYPE. M. C. Z. 10,907. Ecuador: Quevado (F. Rosenberg). 



Yellowish brown, clothed with yellowish and gray hair; hair of head very 

 dense and erect, yellowish, behind on vertex nearly black; male palpi dark, 

 large and heavy, second and third joints subequal, as long as the fifth, fourth 

 about one half as long as fifth. Tips of abdominal segments pale. Wings 

 pale brownish, clothed with yellowish hair, venation as in C. consimilis and 

 C. immaculata, but third fork has a longer pedicel. The male genitalia have 

 the lower appendages long and tapering, the median piece as in C. immaculata, 

 the superior appendages slender, upcurved; seen from above there is no 

 spined plate as in C. immaculata. 



Expanse 12 mm. 



Closely allied to C. consimilis of Peru and C. immaculata of Bolivia, 

 and these are probably the sexes of one species. The male genitalia 

 separates it from the latter; the dark hair on head, and shorter third 

 fork from the former. 



CHIMARRHA TEXANA, sp. nov. 



TYPE. M. C. Z. 10,914. Texas: San Antonio, August (F. H. 

 Snow). 



Black; head with brown hair; antennae, legs and spurs brown; wings 

 brown, with some black hair, a large spot of yellowish white hair behind stigma, 

 reaching one half way across wing, a narrow band of similar hairs over' the base 

 of fourth fork to the arculus, and a broad streak in the basal part of wing. 

 Palpi with the third joint no longer than the second, neither longer than the 

 fifth, fourth swollen below, rather more than one half of the fifth. Wings with 

 discal cell and the radial sector at its base not modified; third fork longer than 

 its pedicel; discal cell reaches back to base of median cell; venation brown, 

 anastomosis, veinlet at base of median cell, and the arculus hyaline white. 



Expanse 15 to 16 mm.
