562 FAMILY XIX. — REDUVIID^E. 



tion near its middle; eyes small, rather finely granulated; joint 

 1 of antennae much surpassing tip of tylus, about half the 

 length of joint 2 ; beak strongly curved, joints 1 and 2 sub- 

 equal ; hind lobe of pronotum smooth and with a curved groove 

 each side ; scutellum short, broad, rugose ; sixth dorsal and 

 ventral of male united to enclose the suborbicular convex gen- 

 ital plate. Eight species are known, seven from tropical 

 America, the other from our territory. 



536 (751). Rhiginia cruciata (Say), 1832, 33; I, 358. 



Oblong-oval, widest behind the middle. Head, pronotum in great 

 part, connexivum and abdomen (in male) reddish or reddish-yellow; 

 scutellum black; a bilobed spot on disk of hind lobe of pronotum, antennae, 

 sterna and elytra, except extreme base of corium, fuscous-brown ; legs 

 dull yellow, the apical fourth of femora and tibia? black or brown; abdo- 

 men with a row of brown or black spots along the sides, in female some- 

 times almost wholly piceous-brown. Structural characters as under sub- 

 family and generic headings. Length, 12 — 16 mm. 



Southern third of Indiana, scarce, April 23 — Sept. 24 ; not 

 taken north of Lawrence and Jennings counties. Ft. Myers, 

 R. P. Park, Moore Haven and Dunedin, Fla., March 1 — April 

 5. In Indiana it has been found only beneath logs on the slopes 

 of open woods ; in Florida it was taken by sweeping vegetation 

 and beating dead pine tops and palmetto leaves. Recorded 

 from six additional stations in Florida and doubtless occurs 

 sparingly throughout that State. It is a species of southern 

 distribution, its range extending from New Jersey west to 

 southern Illinois and south to Florida, Texas, Mexico and Cuba. 

 Except that it occurs beneath logs in winter, nothing has been 

 recorded of its habits. 



Subfamily VII. HAMMACERIN^ Stal, 1859c, 328. 



Large subdepressed species having the front of head broad, 

 porrect, the cheeks surpassing tylus ; eyes large, very protuber- 

 ant ; head abruptly constricted just behind eyes, and immersed 

 in thorax almost to their margins ; pronotum constricted about 

 the middle, its disk granulate, but without impressed lines, 

 front lobe narrower than hind one, its sides rounded ; scutellum 

 short, granulate, its apex ending in two short blunt processes 

 with a notch between them ; elytra entire, reaching tip of abdo- 

 men ; connexivum rather broadly exposed ; legs short, bristly 

 hairy, front coxae short ; both front and middle tarsi ending in 

 a short oval lobe, this spongy beneath ; ventral segments 2 — 5
