Apparently this is a rare species, never collected any-

Thionia quinquata METCALF 

 (1923 Jr. Elisha Mitchell Soc., vol. 38, p. 190) 



Described from a single female taken at Raleigh, No. 

 Car., in early September by C. S. Brimley. 



The original description is quoted here. 



"This species may be recognized by its narow five angled 

 vertex and nearly uniform brown color which is almost 

 uniformly covered with small dark points. 



Vertex narrow, a little longer than broad, the lateral margins di- 

 verging, the anterior margins strongly produced; frons narrow tri- 

 carinate, the lateral margins a little arched; pronotum strongly pro- 

 duced between the eyes; mesonotum long with an evident transverse 

 carina; fore wings with the longitudinal and transverse veins evident. 



General color ochraceous brown with the whole surface of the body 

 including the wings and legs uniformly sprinkled with small black 

 points, veins of the wings and claws black. 



Length to tips of the wings 8.00 mm." 



THE SUBFAMILY ACANALONIINAE (A. & S.) 

 ( Amyot & Serville, Hemipt., pp. Iviii, 520, 1843 Acanonides.) 



This subfamily is represented in North America by the 

 single genus Acanalonia. 



The members have often been confused with those of 

 the Flatinae which they resemble upon superficial exami- 

 nation. They may be differentiated however, by having the 

 elytra without cross-veins on the costal margin, by not 

 being granulated on the clavus, and by the spineless hind 

 legs. On the contrary the Flatinae have the elytra with 

 cross-veins in the distinctly bordered costal membrane, the 

 clavus is always tubercular, and there are from one to 

 tnree spines on the hind legs. 



THE GENUS ACANALONIA SPINOLA 



This genus is confined to the new world and is repre- 

 sented in the United States by nine species, five of which 

 are known from the Southern States. 



The genus may be distinguished by its having the vertex 

 straight or somewhat angularly produced anteriorly, the
