sas and Mississippi. Occurs on Desmodium and other leguminous 

 plants. 



IX. Pseudacysta gen. nov. 



Small oval species having the head short, porrect, inserted 

 in thorax to eyes, its vertex armed with two short converging 

 spines ; antennas slender throughout, joint 1 about one-half 

 longer than 2, 3 twice as long as the others united, 4 fusiform ; 

 pronotum with only a single low median carina, its middle por- 

 tion strongly convex, the triangular posterior portion acute at 

 tip ; paranota represented only by a small pale ear-like append- 

 age at each lateral angle; elytra oval, about one-half longer 

 than abdomen, widest about the middle, their margins feebly 

 curved and tips rounded ; costal area broad with three or four 

 rows of large hyaline cells ; discoidal area not closed behind, 

 both it and subcostal area closely reticulate with very small 

 cells. 



This genus is founded with Acysta persea Heid. (1908, 103) 

 as the type. It differs widely from Acysta Champ. (1898, 46), 

 the latter having four spines on head, the pronotum tricarinate, 

 the paranota extending along the entire margin of pronotum 

 and the discoidal area closed behind. 



471 (680). Pseudacysta persea (Heidemann), 1908, 103. 



Oblong-oval. Body beneath, head, pronotum, except front edge and 

 tip of posterior third, and a bar crossing basal third of elytra but 

 reaching only slightly outside the discoidal area, 

 piceous-brown or blackish; remainder of upper sur- 

 face yellowish-white; legs and antennas pale yellow, 

 the claws and apical half of fourth antennal black- 

 ish. Pronotum subpentagonal, with front side mar- 

 gins obtuse and converging strongly toward apex; 

 posterior portion flat, triangular, acutely pointed; 

 disk finely and densely punctate and with a single 

 entire low median carina. Elytra much surpassing 

 abdomen, their tips broadly rounded; discoidal area 

 long, narrow, not closed behind. Genital segment of 

 male oblong with a small fovea each side. Other 

 (Aftfr Hei'draiann) characters as under generic heading. Length, 2 mm. 

 (Fig. 120). 



Cutler, Fla., April 16 (Gerhard). Taken from the foliage of 

 avocados or alligator pears. Recorded by Heidemann and Bar- 

 ber from Eustis, Baldwin, Orlando, Miami and Ft. Myers, Fla., 

 and probably occurs throughout the southern half of the State.
