30 THE CANADIAN ENTOMOLOGIST. 



If Mr Grote is correct in referring this specimen to sidvs, we must 

 consider W.lkcri as a synonym. A comparison of Walkeri and «»«- 

 ,„,ta with tlre European satdlitia and Guenee's descnpt.on of «rf,«, leads 

 me however, to think tlrat the latter species may be more properly rdent,^ 

 fied with vinulenla than with Walkeri, for in """'*"'; ""f^f*^ 

 primaries noticeably broader and shorter and more rounded at the apex 

 lZ,.sMmia; and the even brick-red color ,s -^y/h^ract- '.c of 

 ,i„nlc„ta, while Walker, has a decidedly purple cast, b -l^-h ■" ^r^ 

 Chatfield's specimen, with the hnes much "°« *^"""-^^ J" *^ 

 reasons I feel very decidedly inclined to consider vmulenta ^ ,dus, 

 ahhcugh I retain the old name in speaking of this speces „r the foUow.ng 



'"*rvae of these five species all have the same fo™ -^ habit are 

 omnivorous and live in a case between two leaves, or w.thm the fold of a 

 sinlleaf-when young making a stlk-covered burrow between two ttbs or 

 Tttg out a cavityL a bud somewhat after the manner of a T°nr.^. When 

 fully matured and somewhat soiled, it ,s hardly possible o sepa ate 

 tlZ Dev-.a and vlnnlenta are very nearly related in th,s (the larval) stage 

 and eparable at a glance from the others, when in good ™" "•-/"^ 

 mata is readily separable from the two remammg species by the yellow 

 ; of the laUline, which I found characteristic of all, wnhotuexcep- 

 on of a very large series of specimens. Morr.scm and Walker, are 

 rmost difficult to separate, but the more even and richer cdor of th 

 fnldoLl and dorsal regions, together with the obliteration o the do 

 and sub-dorsal hnes and the clear white lateral line, render the latter 

 sneces sufficiently recognizable when fresh. The lateral Imes are sub- 

 strata the stigmata black, the body sparsely covered with minute 

 Set' bearing short colorless hairs in all the species. Form cylin- 

 drical, tapering very slightly, head moderate.
