addition to this the coloration of the venter of the abdomen answers 
the description of quaternaria.

O. cincta Olivier. Specimens from Pierce, Vernon, Dane, Door, 
Milwaukee, Washington and Waukesha Cos. 
O. pubescens Day. 12 specimens from Milwaukee Co., 5 from Ra¬ 
cine Co., 7 from Dane Co., 2 from Washington Co. (Cedar Lake), and 
1 from Door Co,. (Jacksonport) all have yellow femora and agree 
otherwise with) the description of pubescens. Of these 6 are males. 
6 males and 3 females from Milwaukee, and 1 female from Racine Co., 
have the femora black with yellow tips, and the abdominal markings 
less triangular than in most of the specimens mentioned above (with 
yellow femora. On account of these characters they run in John¬ 
son’s table (Trans. Am. Ent. Soc. XXTT. p. 251) to lioodiana Bigot, a 
western species, but at the same time the presence of yellow markings 
on the front and vertex points to pubescens , according to Johnson. 
The question therefore presents itself whether these specimens repre¬ 
sent ai black-legged form of pubescens or a variety of lioodiana with 
yellow marks on front and vertex. Furthermore it may be asked 
whether lioodiana is specifically distinct from pubescens.

Euparyphus. 
E. atriventris Coquillett. Type locality: Greely, Col. A female 
from Milwaukee probably belongs here, but the yellow stripe along the 
side of the mesonotum runs from the hind angle to the suture only; 
in the described specimens it extends as far as the humerus. 
E. mutabilis Adams. 1 female taken at Hudson in St. Croix Co., 
July 12th, 1910, agrees with the description, except as follows: The 
frontal medial black line is not produced laterad at its lower end; legs 
with the exception of the coxae entirely yellow; no yellow bands 
along the posterior borders of the ventral segments.
