FAMILY v.— CEDIPODIN^. 151 



Last, forked branch of the discoidal vein of the hind wings 

 usually arising about three-fifths the distance from the 

 base to the apex of the wing, and in the male usually well 

 within the limits of the transverse fuscous belt; closed teg- 

 mina of male surpassing the abdomen by at least one-fourth 

 their length. The very broad posterior femora crossed ex- 

 ternally and internally by three black bands; posterior tibiae 

 reddish yellow, with a broad, pale ring near the base. This 

 species is more slender than the others found in Minnesota. 



Size about the same as tuberculatvs. 



This species is not common, at least but few have been 

 collected, both with yellow or red wings. They prefer 

 sand\^ spots, and fly as earW as Aug. 14. It can readily be 

 distinguished from tuberculatus by the form of the head and 

 pronotum. The wings are usually yellow, often pale yel- 

 lowish-white, sometimes orange or even red. 



Hippiscus tigrinus Scudder. 



Dark brownish fuscous, of robust form and medium 

 size. Head narrowed above and rugulose ; pronotum ex- 

 panding considerably on the metazona, which is centrally 

 a little tumid, the rugosities of the latter, which are con- 

 siderable, ranged more or less distinctly into series parallel 

 to the sides of the process; median carina sub-obsolete or at 

 least depressed between the sucli, distinctly arched on the 

 metazona ; lateral canthi distinct and sharp in the middle of 

 the pronotum, a faint rather broad ashen band next their 

 inner side. Tegmina ashen gray, brownish at base, vitreous 

 on apical third or more, the transverse bars dark brownish 

 fuscous, mostly crossing the wing, those of apical half not 

 at all rounded, with rare exceptions wnth ill defined irregu- 

 lar margins, and extending though fainter to the tip of the 

 wnng; sutural line testaceous. Wings very pale, citron- 

 color at base, pellucid at tip, occasionally with one or two 

 fuliginous cellular spots at tip, the veins and cross-veins 

 blackish on apical portion, yellow on basal, with abroad,
