 black markings. 



An attempt has been made to accommodate the three new species 

 described above in Carpenter's key (1940, p. 215) and its partial 

 modification by Parfin (1956, pp. 207-208). 



Key to the Nearctic Species of Kimminsia 



1. Pronotum with a conspicuous median yellowish stripe, bordered laterally 



with dark brown 2 



Pronotum without such a median stripe 10 



2. Upper part of frons very dark brown, lower part yellowish or light bro\\Ti 



with very abrupt transition K. coloradensis Banks 



Frons more uniformly dark brown, or, if the upper part is darker than the 

 lower, the transition is very gradual 3 



3. Forewing with blackish-brown spots at distal m-cu crossvein and from Cui 



to hindmargin 4 



Forewing with maculations more evenly distributed 5 



4. Forewing nearly uniformly smoky in discal area; small species (forewing 



7 mm.) K. alexandcri, new species 



Forewing with some sagittate maculations in discal area; larger species 

 (forewing 10 mm.) K. posticata Banks 



5. Anal plate of male with a very long dorsal process. . . . K. furcata Banks 

 Anal plate of male without dorsal process 6 



6. Anal plate of male with very long and slender apical process that is terminally 



expanded K. subnebulosa (Stephens) 



Anal plate of male with short apical process 7 



7. Process of anal plate strongly bent forward . . . K. olympica, new species 

 Process of anal plate directed more or less straight downward 8 



8. Process of anal plate short and bent inward K. constricta Parfin 



Process of anal plate moderately long, not bent inward 9 



9. Large species (forewing averaging 11 mm.), costal area broad. 



K. involuta Carpenter 



Smaller species (forewing averaging 9 mm.), costal area of moderate 



breadth K. disjuncta (Banks) 



10. Face, vertex, and pronotum deep black . . . . K. melaleuca, new species 

 Face, vertex, and pronotum yellowish or light brown 11 



11. Face, vertex, and pronotum with scattered red specks . K. longipennis Banks 

 Face, vertex, and pronotum not so marked 12 



12. Forewing without maculation K. brunnea Banks 



Forewing with conspicuous maculations 13 



13. Forewing without distinct transverse bands K. pretiosa Banks 



Forewing with distinct transverse bands 14 



14. Mesonotum with dark-brown anterior border K. schwarzi Banks
