552 FAMILY XIX. — REDUVIHLE. 



sub-erect acute tubercle, hind ones obtuse or subacute. Length, 14 — 17 

 mm. (Fig. 133). 



Daviess Co., Ind., June 15 (W.S.B.). Raleigh, N. Car., 

 July; Cochise County, Ariz., August (Brimley). Resembles 0. 

 apiculatus Reut. very closely in form and color. Ranges from 

 New Jersey west to Missouri and southwest to Florida, Ari- 

 zona, Yucatan and the West Indies. A specimen in the Gaines- 

 ville collection from Lake City is the only one recorded from 

 Florida. Except that it occurs at light, nothing regarding its 

 habits has been recorded. 



Subfamily IV. REDUVIIN^ Amyot & Serville, 1843, 333. 



This subfamily includes species of large size and elongate- 

 oval form having the front of head narrow, either porrect or 

 subdeflexed ; eyes large, coarsely granulated ; antennae slender 

 first joint shorter than second ; hind lobe of pronotum much 

 wider than front one ; apex of scutellum prolonged as a hori- 

 zontal spine ; elytra entire, reaching or surpassing tip of abdo- 

 men, their tips rather narrowly rounded ; legs short, front 

 femora unarmed. Other characters as in key. The subfamily 

 is represented in Tropical America by a dozen or more genera, 

 only four of which occur as far north as the United States. 

 Two of these are represented in our territory. 



KEY TO EASTERN GEXERA OF REDUVIIX.E. 



a. Front of head subdeflexed; antennae inserted on top of the head 

 close to the front margin of eyes, their basal tubercles small; 

 beak stout, distinctly curved. I. Reduvius. 



aa. Front of head porrect, prolonged; antennae inserted on sides of head 

 much in front of eyes, their tubercles prominent; beak rather 

 slender, nearly straight. II. Triatoma.

Large elongate-oval pubescent species having the front of 

 head short, deflexed, hind part constricted close behind the 

 eyes to form a distinct neck; eyes very large, narrowly sepa- 

 rated beneath ; ocelli placed close together near hind margin of 

 eyes ; second joint of beak much longer than the others united ; 

 pronotum as long as wide, its front lobe convex and with a 

 median impressed line, hind one with an obtuse ridge each side
