 Alternated with brown and white along their suture; front blackish. Length

 discal spot; cheeks black, with a marginal yellow cloud below the eye. Pro- 

 notum paler on the anterior margin, disc transversely wrinkled and i^unctured; 

 scutellum witii tiie ordinary divergent pale lines and black discal dots, elytra 

 cinereous, subhyaline, with a brown cloud from the base of the anti-ajiical 

 areoles to tip of the clavus, sometimes extended to the apical margin, their 

 suture pale, alternated with fuscous. Wings slightly obscured, nervures 

 brown. Pectoral pieces piceous black, margined more or less broadly with 

 yellow. Legs and venter brown; connexivum, and sometimes the margin 

 of the ventral segment washed with yellow. Last ventral segment of the 

 female a little longer than the preceding, apical angles rounded, disc with a 

 broad, shallow, longitudinal depression, across which the apical margin is

Described from two males and live female examples taken at 

 Muskoka, Ont., July, 1888. A pale greenish white 9 taken at 

 Lancaster, N. Y. , May 31, 1877; is probably immature. This large 

 well marked form can be distinguished from our other maculated 

 species by its size, luiiform cinereous coloring and the form of the 

 last ventral segment of the female.
