SUPERFAMILY REDUVIOIDE^E. 501 



distinct cells near apex; subcostal area with three or four rows of cells. 

 Length, 2.2 mm. 



Lake Wales, Fla., March 31 (W.S.B.). Stone Mountain, 

 Ga., June 8 {0 shorn) . Recorded heretofore only from Stone 

 Mountain, where it occurs in June on Ilex. Much smaller and 

 with shorter antennae than mutica. 



Superfamily REDUVIOIDE^E Reuter, 1910, 72. 



This superfamily comprises the majority of our predaceous 

 terrestrial Heteroptera. All of them have the front legs more 

 or less modified to form grasping and prehensile organs. They 

 have the head usually more or less cyclindrical ; ocelli usually 

 present; antennae 4-jointed (5-jointed in Pagasus; 8-jointed in 

 Rhiginia), longer than head, the last two joints, except in the 

 Phymatidae, more slender than the others ; beak usually 3- 

 jointed, more or less curved; pronotum and often the head with 

 a transverse groove ; scutellum visible ; elytra without a cuneus ; 

 osteola usually absent ; hind coxae rotatory ; tarsal claws with- 

 out arolia. The superfamily as thus characterized comprises 

 five of our eastern families separated as follows : 



KEY TO EASTERN FAMILIES OF REDUVIOIDB--E. 



a. Pronotum divided into three lobes; head strongly constricted behind 

 the eyes; elytra, except veins, wholly membranous; apical third 

 of front tibiae dilated and compressed; front tarsi 1-jointed, rap- 

 torial; middle and hind tarsi 2-jointed; length not over 4 mm. 

 Terrestrial, usually hygrophilous ; flying in swarms; predaceous. 

 Family XVI. Enicocephalid^e, p. 502. 

 aa. Pronotum not divided into three lobes ; length more than 4 mm. 

 b. Joint 4 of antennae much thickened, clavate or fusiform; front 

 femora very stout, the tibiae short and retractile (fig. 3, c) ; form 

 short, stout, roughly sculptured. Terrestrial or thamnophilous; 

 predaceous. Family XVII. Phymatid.-e, p. 503. 



bb. Joint 4 of antennae slender, not clavate or fusiform; front femora 

 not strongly thickened; form slender, often exceedingly so. 

 c. Prosternum (except in Carthasis) with a longitudinal, median, 

 minutely transversely striated, stridulatory groove between the 

 front coxae and receiving the tip of beak; beak 3-jointed, the first 

 joint usually stout and more or less curved; head with a trans- 

 verse groove between or behind the eyes. 

 d. Body and antennae linear or extremely slender; ocelli absent; 

 front coxae greatly elongated, reaching or surpassing apex of 

 head, their cavities opening forward and downward; elytra, 

 except veins, membranous, the usual divisions of clavus, corium, 

 etc., wanting. Terrestrial or thamnophilous ; predaceous.
