[127] NOTES ON SOME LEPIDOPTERA. 239 



Xylina lambda (Fabr.), var. Thaxteri Grote. 



The reference of X. Thaxteri as a variety of X. lambda, by 

 Dr. Speyer, has been noted on page 120. * From the examina- 

 tion of the photograph of X. Thaxteri given in the Grote 

 Check List, Pt. ii, fig. 3, Dr. Speyer was led to express his 

 opinion* that it was but a variety of the European X. lambda. 

 Mr. Grote, in its description (Bui. Buf. Soc. Nat. Sci., ii, p. 

 196), had instituted a comparison between it and Zinckenii, 

 under which name X. lambda was formerly known. 



The recent examination by Dr. Speyer of a number of ex- 

 amples of X. Thaxteri has confirmed the opinion above 

 expressed. He finds it to " correspond with the European 

 species in all particulars except in that its primaries are a 

 little broader, and its secondaries somewhat more excavated 

 on vein 5. X. lambda had heretofore been known under three 

 varieties ; Zinckenii Treits., rufescens Men., and somni- 

 culosa Hering. Thaxteri is now the fourth well marked 

 variety ; in its sharp markings, it resembles Zinckenii var., 

 and in its color, rufescens var." 



Hypena humuli Fitch. 



In Harris' Report on the Insects of Massachusetts, p. 345 

 (Edition of 1841), the author, after describing some caterpil- 

 lars infesting the hop-vine, says of the moths proceeding 

 from them, that "they have been named [by him] the Hypena 

 humuli, on the supposition that they are distinct from the 

 Hypena rostralis or hop-vine snout-moth of Europe." 



" These moths are readily known by their long, wide, and 

 flattened feelers, which are held close together, and project 

 horizontally from the fore part of the head in the manner of 

 a snout. The antennae in both sexes are naked and bristle- 

 formed. The wings vary in color, being sometimes dusky or 

 blackish brown, and sometimes of a much lighter rusty brown 

 color. The fore- wings are marbled with gray beyond the 

 middle, and have a distinct oblique gray spot on the tip ; they 

 are crossed by two wavy blackish lines, one near the middle, 

 and the other near the outer hind margin ;. these lines are 

 formed by little elevated black tufts, and there are also two 

 similar tufts on the middle of the wing. The hind wings are 

 dusky brown or light brown, with a paler fringe, and are 

 without bands or spots. The wings expand about one inch 

 and a quarter."
