viz. T. comes var apicalis De Long^ It has the markings on cia- 

 vus and on coriuni anterior to costal phiqiic sulphur yellow, and 

 from costal plaque to cross-veins and sometimes streaks on apical 

 veins orange-retl; scutellum and parts anterior pale yellow, with 

 translucent to sulphur-yellow markings. Through the kindness 

 of Mr. De Long I have examined two specimens from the type lot 

 collected by him at Covington, Tennessee, June 18, 1915; the 

 form pertains to inaculata rather than cojncs.
