black spot behind each incisure; basal joint of beak with three black 

 spots each side. Apex of genital plate of male with a short obtuse erect 

 spine. Length, 12 — 13 mm. (Fig. 142).

 (Frost). Taken by sweeping herbage 

 along roadsides. This species is much 

 less common in Indiana than is barberi, 

 having been found only in the Lower 

 Austral Life Zone of the southern third 

 of the State. Its general range is ap-

(After Riley). barberi, but on account ol the long time 



confusion of the two forms is difficult 

 to state. Van Duzee gives it as New England west to Colorado 

 and Wyoming and south to Florida, Oklahoma and Texas, but 

 the more northern of the records upon which his distribution 

 notes are based should undoubtedly in part be referred to 

 barberi. It has been heretofore recorded in Florida only from 

 Crescent City and Jacksonville. Uhler (1878, 427) states that 

 "near the seacoast of New Jersey it is sometimes met with in 

 great numbers on the small oak and hickory trees," and later 

 (1884, 282) says that "the eggs are often glued to the bark of 

 pine trees and covered by a waterproof gum which effectually 

 excludes the rain, dries and hardens, and does not incommode 

 the young when they push up the lid-like ends to make their 

 way out." The amount of black on the front lobe of pronotum 

 varies from a mere central dash in Indiana specimens to the 

 covering of the greater part of the disk in some of those from 

 Florida. 



548 (780). Pselliopus barberi Davis, 1912, 21. 



Form of ductus, but averaging slightly larger. Bright orange-yel- 

 low ; head above black with a yellow spot on vertex ; pronotum with only 

 the tubercles on humeral angles and a small lunate spot on margin 

 behind them black; black of scutellum confined to the area bounded by the 

 V-shaped ridge of base, often wholly wanting; legs and antennse an- 

 nulate with black as in ductus; connexivum with black spots as there. 

 Apical half of scutellum less flattened, its tip more narrowly rounded, 

 the disk with a well defined carina extending from the apex of the basal 

 V to tip. Genital plate of male with apical spine longer, more acute 

 and directed obliquely forward. Length, 12.5—14 mm.
