stant differences between the two, and resurrected Say's name 

 from synonymy.-'" He stated that calceata "seems to be confined 

 to the territory east of the Appalachians and appears to be 

 more characteristic of the highlands and mountain districts." 

 Hart (1919, 184) has since recorded that "the species had al- 

 ready been recognized by Dr. S. A. Forbes as distinct in our 

 collection" from examples taken at Urbana, Towanda and Ta- 

 maroa, 111., May 2 — Sept. 22, and that specimens from Ken- 

 tucky and Florida are in the Bolter collection. 



75 ( — ). Thyanta accerra McAtee, 1919, 16. 



Broadly oval, subdepressed. Greenish-yellow to brownish-green, 

 more or less sprinkled with dark brown or fuscous punctures, these 

 forming faint dark markings on basal half of pronotum and corium 

 and on the scutellum more aggregated to form a dark border each side of 

 a vague pale median stripe reaching from near base to apex; pronotum 

 with front side margins edged very narrowly with black and with two 

 blackish dots on middle of apical portion; corium with numerous widely 

 scattered smooth, slightly elevated white spots; membrane with many 

 distinct oblong black dashes along the veins; connexivum reddish-yellow 

 with an oblong blackish spot on each incisure; under surface and legs 

 yellow or greenish-yellow, sprinkled with numerous small brownish dots ; 

 spot near spiracles and a point on the end of each ventral incisure black. 

 Form and structural characters much as in calceata. Joints 2, 4 and 5 

 of antenna? subequal in length, each slightly longer than third. Front 

 side margins more obviously concave than there. Length, 9 — 11 mm.; 

 width, 5 — 6 mm. 



Dunedin, Fla., Nov. 2 — March 20. Taken frequently by 

 sweeping low shrubs, huckleberry, etc., in open pine woods and 

 along the bay front. Described by McAtee as a variety of cus- 

 tator, from specimens taken in October at Barachias, Ala., and 

 San Antonio, Tex. Regarded by Barber (Ms.) as a form of 

 casta but in my opinion a valid species, or, if a variety of any- 

 thing, one of calceata. The white spots on corium, black dashes 

 on membrane, dull yellow stripe vaguely bordered with fus- 

 cous on scutellum and spotted connexivum are its most promi- 

 nent differential characters. 



76 (162). Thyanta antiguensis (Westwood), 1837, 36. 



Broadly oval, subdepressed, small for the genus. Above dark green, 

 fading to greenish-yellow, thickly marked with small brownish punctures; 

 antenna? greenish, the outer joints tinged with reddish; pronotum with
