FAMILY XIX. — REDUVIID^:. 



This is the most common Reduviid in Florida, having been 

 taken by me at nearly all collecting stations and recorded from 



many others. At hand also 

 from Agricultural College, 

 Miss. (Weed). From No- 

 vember to April it occurs in 

 Florida on weeds and low 

 shrubs in old fields and 

 along roadsides or on tall 

 dead grasses along the mar- 

 gins of ponds; usually on 

 some plant whose colors 

 blend with its hues. The 

 whole front part of the 

 body, including head, legs 

 and antennae, are often al- 

 most concealed by the de- 

 bris which it has accumu- 

 1 a t e d in its foraging. 

 Ranges from Virginia 

 southwest to Florida, Texas, 

 California and Mexico. 



(Original). 



542 (771). Zelus exsanguis (Stal), 1862, 452. 



Elongate, slender, subparallel. Greenish-yellow fading to dull straw- 

 yellow; head, hind lobe of pronotum and scutellum sometimes fuscous or 

 even black; spines of humeral angles usually in part or wholly black, 

 membrane pale brown. Second antennal longer than in our other species, 

 nearly half the length of first. Hind portion of head gradually taper- 

 ing backwards. Pronotum as in key, its front angles nodulose; hind 

 lobe subhexagonal, broader than usual. Length, 15 — 17 mm. 



Frequent throughout Indiana, May 10 — Dec. 11 (W.S.B.). 

 Ashland, Mass., May 2 ( Frost) . Occurs in summer on low herb- 

 age in dense upland woods or on foliage of shrubs, especially 

 the staghorn sumac, along woodland paths and roadsides; in 

 fall on the ground beneath cover and possibly hibernates as 

 imago. It is our most widely distributed Zelus, ranging from 

 Quebec and New England west to the Pacific and south to 

 Florida, Mexico and Panama. The only Florida record is that 

 of Uhler (1878, 428) without definite station. It varies much 

 in color and in the length of the spines of humeral angles, these 

 sometimes mere tubercles. The males are more often black 

 above than the females, and have the basal half of first anten-
