o68 THE CANADIAN ENTOMOLOGIST 



Smith published a photop:raph of his t>'pc in the Canadian 

 Kniomclogist, lea\ing the identity of his species be>ond doubt. 

 I also possessed a specimen "Xd. type" with Walker's simplex. 

 But as that comparison had been made at a time when I had failed 

 to recognize two species, 1 w ;is unable to place any reliance on the 

 comparison. I was, howc\er, quite satisfied 5s to the distinctness 

 of cnicialis from pallidior. Hampson published a figure of pollidior, 

 made from another, of the type, sent to him b\- Smith, which is 

 (|uile recognizable. His woodcut of simplex is not so good, but 

 my notes on Walker's type were such as to lead me to suspect 

 strongly that I had made a mistake and that Smith also had fallen 

 into his oft-repeated error, in that, whilst recognizing two very 

 rl(]sely allied species, instead of seeking a re-identificaticn of simplex, 

 he had chf:;sen to assume its correctness, and created a synonym. 

 I accordingly sent Sir (icorge Hampson a few specimens of each, 

 stating my suspicions, carefully pointing out the distinctive charac- 

 ters, and requesting him to re-examine Walker's type. His 

 diagnosis was in accordance with my suspicions, and I ha\e since 

 \isited the British Museum and corroborated his exidence, which 

 results in the s\ nonymy here cited. I regret being unable, at 

 present, to publish a close comparison of the two species, for 

 reasons given abo\e, but feel safe in emphasizing the following 

 points: Cnicialis is slightly longer-winged than si)iipl(\\\ the 

 discoidal spots are a trifle smaller, and the subterminal line or 

 series of blackish streaks is arranged so as to form two oljlifpie 

 triangular shades. In simplex they form a more regular and e\en 

 series, about parallel with the termen. The two species occur 

 together and are not rare on Vancouver Island. Whilst cnicialis 

 has usually the clearest white ground colour of the two, both have 

 a dark, almost suffused, grey variation. I have been misled into 

 mistaking the extreme dark variations of either species for one 

 form, the corresponding light variations for the other, and must 

 warn others against falling into this error. It must be admitted 

 that the jtwo species are not easily distinguished imlcss well known. 



The synonymy stands as follows: — - 



Xylomiges simplex Walk. 

 " pallidior Smith. 



Xylomiges cnicialis Harr. 



" simplex Smith et ab. nee Walk.
