196 NORTH AMERICAN MUTILLIDAE 



the lower lateral angles of this a straight carina on each side proceeds at a wide 

 angle almost to the side of the reflexed margin of the ctypeus, enclosing a 

 smooth, polished, equilateral triangle with truncate apex. Third segment of the 

 antennae below wider than long, almost as long as the pedicel, hardly more than 

 half as long as the fourth segment. 



Humeral angles very prominent, strongly carinate, the carina below bent 

 and traversing the side pieces of the pronotum almost cephalo-caudad ; prono- 

 tum with side pieces impunctate, dorsally with the mesonotum very coarsely 

 punctured, sparsely pubescent; scutellum convex but hardly gibbous, coarsely 

 punctured; mesopleura coarsely punctured, densely pubescent; dorsal sur- 

 face of propodeum with two rows of large reticulations or areoles, becoming 

 smaller laterally, the median basal one largest; dorsal surface separated from 

 the smooth, polished posterior surface by a prominent transverse arched rim; 

 sides irregularly reticulate. 



Veins piceous, wanting in the hind wings, there being no closed cells, but 

 Sc+R+M and a short weakly chitinized piceous stump of another vein, are 

 present, but without violaceous reflections. 



Petiole rugose, rather cyUndrical, transverse, keeled ventrally, the keel 

 with an anterior recurved tooth; second segment coarsely evenly punctured, 

 the punctures becoming sparse and finer posteriorly; remaining segments each 

 with a median keel, and finely, sparsely punctured, the last more closely but 

 not roughly nor coarsely; last ventral segment buff, weakly punctured. 



Type material. — Holotype: Bainbridge, Decatur County, 

 Georgia, 15 to 27 July, 1909, collected by the author. Collection 

 of Cornell University, No. 106.1. One paratopotype, same date. 



Dedicated to Paul Battle of Bainbridge, Georgia, my faithful 

 companion on many a collecting trip. 



Ephuta scrupea Say 



1836. MutUla scrupea Say, Journ. Boston Soc. Nat. Hist., 1 : 297, d". 



Ocellar measurements are as follows: transverse diameter of 

 the posterior ocelli .13 mm., of the front ocellus .16 mm.; distance 

 of the former from each other .19 mm., from the eyes .40 mm., 

 from the front ocellus .10 mm. 



. Of a large series of specimens of Ephuta collected by Mr. 

 Nathan Banks in Virginia, twenty-eight belong here and nine- 

 teen in pauxiUa. In deciding to which of these two species 

 Say's name scrupea should apply, I was guided by his description 

 of the propodeum, which would not seem to fit pauxilla so well 

 as the other. The remainder of the description might apply to 

 either. 



Of the specimens assigned by Fox^ to scrupea, those from Con- 

 necticut and Delaware belong to pauxilla, the one from Texas
