I was quite surprised to find that Mr. Grote's type in the British 

 Museum was my si^ecies. The specimens originally labeled by mo 

 came from Dr. Hulst's collection. Afterwards I found in the Riley col- 

 lection in the National ^luseum a specimen labeled by Mr. Morrison 

 ^'■Pseudorthisia licctinaia tyiw.'^ I therefore did not describe the spe- 

 cies in 1887 with the other species named by me. Subsequently I com- 

 pared the specimen with the original description and concluded that it 

 could not well be intended to apply to this species and renamed it. 

 The National Museum specimen is labeled by me as type, and a "type" 

 is also in the Tepper collection. 



[A number of Colorado specimens seen recently make it certain that 

 this is but a form of JiltoraUs Pack. Pectinata may stand for the 

 variety with distinct median lines.] 



P. haesitans Wlk. 



1856. Wile, C. B. Mus., Hot., x, 329, Jyrotis. 



Habitat. — llocky Mountains. 



The tyi)e is a well-preserved male, the antenna? distinctly pectinated, 

 the other characters as in Pachnobia, save that it has the aberrant, dull, 

 ash-gray color of my cinerascens. It is not unlike this latter save in 

 antennal characters. The median lines are single, t. p. line crenate, 

 cell blackish between the ordinary spots.

Walker's type is in the British Museum; but I could not find any 

 specimens labeled by Mr. Grote. Mr. Morrison's type is in the Tepper 

 collection, Agricultural College, Michigan.
