BY CHARLES P. ALEXANDER. 

 Urbana, Illinois. 



The majority of the species considered in this part were secured by Dr. 

 P. W. Claassen in Estes Park, Colorado. Others were taken by Messrs. Prison, 

 Lindley and McAtee. The writer is indebted to all the above gentlemen for 

 the privilege of studying this material. Unless stated otherwise, the types of 

 the species are preserved in the writer's collection. 



EUiptera coloradensis, new species. 



General coloration dark brown, the mesonotal praescutum brownish black; 

 wings grayish subhyaline, the cord and outer end of cell 1st M^ indistinctly seamed 

 with brownish gray; cell 1st AP closed; Sc^ located before the origin of Rs. 



Female. — Length 8 mm.; wing 10 mm. 



Rostrum and palpi dark brown. Antennae dark brown, the flagellar seg- 

 ments oval. Head dark brown. 



Pronotum obscure brownish yellow. Mesonotal praescutum obscure yellow 

 with three broad, brownish black stripes that are practically confluent, restrict- 

 ing the ground-colour to the humeral region and the lateral margins; scutum 

 yellow, each lobe with two confluent brownish black areas; scutellum obscure 

 yellow; postnotum dark brown. Pleura brownish yellow, the mesepisternum 

 darker; mesosternum between the fore and middle coxse brownish black. Halteres 

 pale, the knobs a little darkened. Legs with the coxae and trochanters yellow; 

 remainder of the legs dark brown, the femora paler basally. Wings grayish 

 subhyaline, the costal region indistinctly more yellowish; cord and outer end 

 of cell 1st M^ narrowly seamed with brownish gray; veins dark brown; stigma 

 lacking. \>nation: Sc rather short, 5c^ ending about opposite two-thirds the 

 length of Rs, Sc^ located before the origin of Rs; R pale at the apex; R^ bent 

 suddenly cephalad at the tip so that cell R^ is widened at its outer end; deflec- 

 tion of i?*+^ slightly angulated; r-m oblique in position; cell 1st M^ closed, a 

 little shorter than vein M^+2 beyond it; basal deflection of Cu^ just before the 

 fork of M. 



Abdomen dark brown, the pleural integuments paler, the genital sei^ment 

 paler. Ovipositor with the valves elongate. 



Habitat. — Colorado. 



Holotype— 9 , Fall River, Estes Park, August 24, 1919, (P. W. Claassen). 



Erioptera (Erioptera) subseptemtrionis, new species. 



Male. — Length 4.5 mm.; wing 6 mm. 



Similar to E. septemirionis O. S., differing as follows: 



General coloration dark brown, the lateral margins of the praescutum and 

 two stripes on the thoracic pleura paler. Legs dark brown, the femoral bases 

 paler. Wings darker with the stigma much more distinct; veins straighter, 

 jy^i+2^ j^z ajj(^ Q^i showing little tendency to bend toward the wing-tip as in 

 E. septemtrionis. Male hypopygium with the spine of the inner pleural ap 

 pendage much longer than in septemtrioriis, appressed to the appends ge and 

 almost straight; the blade of this appendage is flattened and without a concave 

 depression formed by a short, lateral ridge as in septemtrionis. 



Habitat. — Colorado, 



May, 1920
