this part is largely pale in insidiosus. Trlsticolor cannot be 

 considered even a geographical form since I have recently de- 

 tected it from several localities in New England, where it oc- 

 curs in company with the typical variety. These eastern ex- 

 amples agree with specimens from the west and Van Duzee 

 concurs in their identification as trlsticolor. In his monograph 

 of the family Renter says of insidious, "A Tr. tristicolore B.- 

 Wh. vix nisi colore hemielytrorum divergens," but treats them 

 as separate species. His var. /? of trlsticolor, "Clavo margine 

 exteriore macula albido-testacea ante apicem" may be consid- 

 ered an intermediate leading toward the condition characteris- 

 tic of the typical variety.
