middle, one on costa, and one near tip, the extreme tip jet black; fringe dark gray 

 to blackish, whitish at two spots on front margin, and two spots behind ; hind wings

Several from Washington, D. C, September, at light.

 elsewhere ; the white part beyond middle is indistinctly divided by a dark stripe ; 

 fringe mostly dark gray, white at white spots ; hind wings pale, with long pale gray 

 fringe behind. The ventral lobe of male is slender and reaches nearly to tip, much

Several specimens from Falls Church, Va. , May i. 



Allotrichia flavida, new species. 



Head blackish, with yellowish hair ; antennse yellowish, and with yellow hair, 

 thorax brown, with yellowish hair, two especially conspicuous tufts from the pronotal 

 warts ; abdomen yellowish brown, dark at tip, clothed with whitish hair; legs pale 

 yellowish, with almost white hair. Wings yellowish, some brown and black hair on

Three females from Ft. Collins, Colorado, June 9. 



Order CORRODENTIA. 

 Myopsocus coloradensis, new species. 



Head black, an elongate pale spot on each side of the nasus, and sometimes a 

 spot each side on vertex. Antennae pale, tips of joints black ; thorax black, with a 

 large pale spot on each lateral lobe ; abdomen black ; coxse black, femora black 

 except pale tip, tibia pale except black tip, first tarsal joint pale except black tip, and 

 rest of tarsus black. Wings mostly black, paler on base and beyond middle, leaving 

 a broad, oblique black band across middle of wing, several white spots on margin, 

 and along veins are many white dots ; the whole similar to M. sparsus, but blacker. 

 It differs at once from M. sparsus by the shorter antennae, the third joint (first long 

 joint) being plainly shorter than the width of the head from eye to eye, while in J\I. 

 sparsus the third joint is fully as long as width of head. Venation similar to J\J. 

 sparsus, but the pterostigma is scarcely as wide, and the discal cell is usually faintly 

 pedicellate. Length 4. 5 to 5 mm. 



Several specimens from Ft. Collins and Boulder, Colo. The latter 

 taken by Professor Cockerell under stones on Flagstaff Hill.
