melanopyga it appears variable, a fact which probably accounts for 

 several synonyms and many misidentifications. 



It is quite likely that subsequent workers may desire to separate 

 these borers into two genera upon habitus combined with larval and 

 life-history characters; but if such a division is made, it apparently 

 must be as suggested by Barnes and McDunnough, (1914, Contr. Nat. 

 Hist. Lep. N. A., II, (5), 200). For the present, the authors are 

 inclined to agree with Dr. Forbes, (1914, Jour. N. Y. Ent. Soc, XXII, 

 28), that there is little use of now separating into two genera; and 

 propose that the oldest name, Bellura, be used. 



Bellura obliqua race pallida nov. 



Primaries: pale luteous-brown ; wliilish shade at base of costa present; 

 orbicular more or less obscured, tinged with red ; reniform rather elongate, 

 oblique, reddish filled ; median shade absent ; t. p. line produced to points on 

 the veins ; s. t. line sinuate, marked by black dots on the veins ; terminal area 

 pale purple. Secondaries : similar, tinged with pink ; with a somewhat darker 

 discal spot. Cl}T)eal tubercle present, strong. Anal tuft of female white. 



Expanse: about 44 mm. 



The present is the antonym of hrchmei B. & McD., the blackish 

 shades and markings reduced. From the characters now used, this 

 might be considered a valid species ; but the authors prefer to tenta- 

 tively list it as a western race of obliqua Wlk. 



A male and female from Colorado, (Oslar), may be the same; 

 altho some specimens collected in Colorado by Bruce are as dark as 

 some of the paler eastern obliqua. A single specimen from Edmonton, 

 Alberta, sent by Mr, D, Mackie for identification is presumably the 

 same as the types of pallida. 



Knowing that careful study of life-histories will be a necessary 

 factor in determining what constitutes specific characters in these 

 insects, and to avoid the chance of a mixed type series, the types are 

 restricted as follows. 



Type locality: Vineyard, Utah, (Spalding). 



Number and sexes of types: Holotype 9, Paratype 9, both 16 Aug. 1912.
