36. Jlipf^iicui obicurui Scudd. 



15. C. — Recorded from ihis Province by Scudder* and from 

 Vernon, as //. Cu/i/ornicus, U alker. 



The spccitncns from Vernon exhibit two types of coloration. 

 In one ll>e inaikings are distinct, as in //. iteglectiis, in the other 

 they are obscured with brown and the tegniina arc without the 

 yellow siilural stripe. As these specimens show no structural 

 differences and were all taken together, there can hardly be a 

 doubt that they belong to the same species. Ihe di>tinctly- 

 marked individuals are scarcely separable from //. tieg/ectiis, aid 

 I doubt very much if they are specifically, or even racia'ly, 

 distinct from that species.

I have included imder //. tigiinui many sjieiimens 

 which do not agree with Scuddei's description in all respects. 

 In fict, I find it impossible to separate //. lalf/asciatui, ti\^t iiiui 

 and zopotecus by the characters given by Scudder. The course 

 of the intercalary vein, the develupment of the tubercles of the 

 pronotum, the width of the fuscous band of the wings and the 

 extent of the maciilation (.f the tegmina are all very variable 

 charactirs. .As, however, I have seen but few authentically de- 

 termined specimens of these three forni«, I m.ike .is \et no
