146 THE CANADIAN ENTOMOLOGIST. 



Prof. Smith tells me that I have " every form of the species which has 

 received a name." I divide the species into four series as follows, and 

 have nothing that I can call an intergrade between any two of them : 



1. Ground colour red. {Ochrogasier, Guen.). 



I a. Ground colour red, with black basal streak, claviform and 

 discoidal cell. {Gularis, Grote). 



2. Ground colour ochreous. 



2a. Ground colour ochreous, ditto as above. {Ttirris, Grote.) 

 Some of (2a) have a distinct darker central band, scarcely traceable in 

 any of the other series. The variation in each series by itself, both in 

 colour and maculation, is enormous. Form (la) seems to be the least 

 common. I never questioned the unity of the forms, perhaps taking it 

 rather for granted that such a common and widely-distributed species must 

 have been carefully bred long ago, but quite recently Prof. Smith wrote to 

 me, "I am beginning to seriously doubt the identity of all the forms placed 

 under the same name." Incidentally lie expresses the same doubt con-

I am fairly well satisfied that I have two closely-allied but distinct 

 species, standing under the above names, and both Prof Smith and Sir 

 George Hampson confirm my belief that they are the two species indicated. 

 I think I have them properly separated as species, but whether I have them 

 under the right names or reversed is a more open question. I have had 

 no opportunity of seeing the original descriptions, and in all other attempts 

 to correctly place them I meet with confusion everywhere. Briefly de- 

 scribed, my two series are as follows (I mention merely the distinctive 

 features): 



/da/ioensis, eight (J (J and seven $ V • Pale reddish-brown or gray- 

 brown, the darkest specimen having something of a purplish tinge. 

 Costa, clear gray; collar of same, or nearly same colour as costa, with a 

 black line. Discoidals uniformly concolorous with costa. A series of 

 black sagittate dashes preceding s. t. line, in most of the specimens 

 extending more than half way to t. p. line. In one specimen only there 

 is scarcely a trace of these dashes. 



Furiivus, fourteen ^ ^ and twenty ? 9 . A slightly shorter winged 

 species, Costa gray, sometimes clear, but generally tinged with reddish-
