Rhynchagrotis rufipectus, Morr. 



This species extends across the continent through the more northern 

 parts 'Of the country, but does not seem to extend southward in the Atlantic 

 Coast region nor in the Mississippi Valley. It does, however, extend 

 southward on the Pacihc Coast, and is recorded from Los Angeles Co., 

 in Southern California. In general the species is easily recognized, and 

 does not vary much in any one region. There is, however, a very decided 

 difference between the small dark gray specimens of the New England 

 States and the large reddish-gray examples that I have from Sierra Nevada. 

 With examples of the extremes only at hand, two species would be readily 

 accepted. Fortunately, in the series of examples from Kaslo, both forms 

 were found, taken apparently on the same dates. The gradation comes in 

 the form of a reddish powdering over the dark lustrous gray of the typical 

 form. As this intensifies, the gray seems to disappear, until only the reddish 

 overlay remains, conveying the impression of a more thinly-scaled wing, 



Rufipectus and brunneicoUis are distinguished from all our other 

 species in having the head and collar velvety-brown, 



Rhynchagrotis brunneicoUis, Grt, 



Has about the same general distribution in the E:istern United States 

 as the preceding, but seems to extend further southward along the 

 Atlantic Coast, and does not extend westward through Canada into 

 British Columbia^ nor have I seen it from the Pacific Coast at any lime. 

 It is larger than rufipectus, reddish and brown instead of gray, and the 

 transverse lines are geminate instead of single. 



Rhynchagrotis jninimalis, Grt. 



This species is rarely represented in collections, and specimens so 

 named are, as a rule, incorrectly determined. It differs from practically 

 all of the subsequent species by the single, instead of geminate median 

 lines, and in that character is not unlike rufipectus, which it does not 

 resemble in any other way. I have seen it only from Maine, Colorado 

 and British Columbia, and always in isolated specimens. In colour it 

 resembles anchoceiioides, and it may be mistaken for a di-reputable form 

 of that species. 

 Rhynchagrotis bimarginalis, Grt. 



Not in my collection and apparently very rare. Has been taken only 

 in New Mexico, and is easily recognizable by the pale yellow costa and 

 more bluish terminal space ; it is quite characteristic, and its only ally is 

 the next species.
