22-i THE CANADIAN ENTOMOLOGIST. 



Rhyiichagrotis vittifrons, Grt. 



All m)' specimens are from Stockton, Utah, September and October, 

 or Fort Wingate, New Mexico, in September. The species is lustrous 

 smoky-blackish, without obvious maculation, but with collar and costal 

 margin from base to t. p. line broadly pale yellow. It differs from the 

 preceding in that the terminal space is concolorous with the main body of 

 the wing. The species is also recorded from Glenwood Springs, Colo. 



Rhynchagiotis foriiialis, Grt. 



This is an extremely interesting form from the Pacific Coast, extend- 

 ing from Southern California to Vancouver, and it needs a long series to 

 appreciate its variations. In ground colour it ranges from red to deep 

 chocolate-brown, more or less powdered or washed with bluish, the costal 

 area paler and with the bluish more conspicuous, invading the open 

 V-shaped orbicular, 'i'he transverse maculation is largely lost and the 

 terminal area is usually bluisli, or at least a little paler. \\\ the normal 

 form there is a black streak at base below the median vein, and ths cell 

 before and between the ordinary spots is black. This is i\\Q facuhi of 

 Grote, according to Hampson, and it varies in the direction of losing the 

 bbick filling of the cell. In the type oi/ormalis the black basal streak is 

 lost, and this varies iii the direction of losing the black filling in the cell, 

 and finally the black tip to the collar. This seems to make it a difficult 

 species to recognize, and so it is from limited material ; but these uniform 

 examples are in the minority, and, in almost every instance, there is a 

 darkening of the ground that locates the usual black markings. All the 

 examples before me, 15 in number, are from California, and illustrate the 

 extreme range of variation above given. 



Rhynchagrotis cost at a ^ Grt. 



This is not represented in the material before me. I have a coloured 

 figure made from the type many years ago, and that is very like Hampson's 

 ])ublished figure. The species is pale red-brown in colour, the costa 

 broadly paler, not crossed by the median lines, orbicular broadly 

 V-shapcd. The t. a. line is obscure, and the basal streak seems to merge 

 gradually into the black filling of cell. 



Rhync/iagroiis confnsa, Sm. 



Resembles costata in a general way, but the transverse lines are 

 much better marked and, at base, the black streak usually curves down- 

 ward when it reaches the t. a. line, so as to form its inner defining element.
