their bases and inner margins; both sets of wings crossed by a common dark 

 medial shade line, and with distinct discal marks. 

 Expanse: 42 mm. 



This species bears a closer resemblance to mcdialis than to 

 palescens in color and course of the t. p. line, while the type of clavi- 

 form is similar to palescens. The antennae are less heavily serrate 

 than in either of the allied species placing the insect in Group III of 

 Hampson's Hydrcecia, (Cat. Lep. Phal. B. M., IX). 

 Type locality: Ft. Calgary, "N. W. Brit. Columbia." 

 Number and sexes of types: Holotype $ , "VIII, 16".

This insect has been the cause of considerable dispute in the past. 

 In the Henry Edwards Collection three specimens were found under 

 the name obliqua. Two of these were labeled "4410" which is the 

 Henry Edwards number given by Harvey in his original description. 

 One of these specimens, bearing a name label, "Apamea obliqua 

 Harv." agrees well with the description except in size, being 46 instead 

 of 36 mm. which may be due to a typographical error. 



None of the Harvey or Grote material remains in Buffalo, accord- 

 ing to Dr. William Alexander, who is in charge at the Buffalo 

 Academy. 



Grote, (1881), mentions the receipt of a pair of specimens of 

 obliqua from Henry Edwards. The male and female under the label 

 obliqua in the British Museum almost undoubtedly represent this pair ; 

 and not the original specimen sent to Harvey. Hampson's description 

 of them (1910) apparently represents G. .vimena, described in this 

 paper. The British Museum specimens certainly do not answer the 

 original description of G. obliqua. 



The third specimen in the Henry Edwards Collection, mentioned 

 above, is from "Sier. Nev. Cal", apparently agrees well with a speci- 

 men from Truckee in the Barnes Collection and these two specimens 

 constitute the types of G. ximena, n. sp.
