320 FAMILY IX. — ARADID^E. 



The foregoing are the salient features of the original de- 

 scription. It is known only by the unique female type taken at 

 Tampa, Fla., April 27, 1875. 



III. PlCTlNUS Stal, 1873, 140. 



In structure and general appearance our only member of this 

 genus is closely allied to Neuroctenus but differs in the lack of 

 a carina on sides of ventrals 3 — 5 and in having the third an- 

 tennal distinctly longer than second. From Aneurus, the only 

 other genus having the membrane devoid of veins, it is easily 

 known by the scutellum being triangular with apex acute and 

 by the fourth antennal being shorter than third. Our species 

 has the base of thorax squarely truncate instead of "subrotun- 

 dato-truncato" as stated by Stal in his key to genera. One of 

 the eight known species occurs in the southern states, the 

 others in Central and South America. 



252 (402). Pictinus aurivillii Bergroth, 1887, 247. 



Elongate-oblong, slightly wider behind the middle. Above reddish- 

 brown, the membrane and scutellum somewhat darker; connexivals each 

 with basal half dull yellow; under surface and legs brownish-yellow, the 

 genital region darker. Antenna? reaching only to middle of pronotum, 

 reddish-brown, the apex of fourth joint paler; joint 1 stout, subclavate, 

 slightly surpassing tip of tylus ; 2 slightly shorter and more slender, two- 

 fifths the length of 3, the latter longest, twice the length of 4. Head 

 relatively small, slightly longer than wide, narrower than front margin 

 of pronotum; antenniferous tubercles prominent, conical, obtuse; post- 

 ocular ones obsolete. Pronotum subquadrate, one-half wider than long, 

 sides sinuate in front of middle, front margin concave, disk finely and 

 evenly granulate, the transverse impression wide, shallow, ill-defined. 

 Scutellum broadly triangular, its margins thickened and disk with obtuse 

 percurrent median carina. Connexivum very broadly exposed. Membrane 

 finely rugulose without distinct veins. Length, 4.5 mm. 



Crescent City, Fla., taken from beneath bark of dead orange 

 trees (Cornell Univ. Coll.). Known elsewhere only from Georgia 

 and Bayou Sara, La. 



IV. Nannium Bergroth, 1898, 100. 



Very small oblong or oblong-oval species having the head 

 short, broad ; antennae slender, nearly as long as head and 

 thorax united ; beak reaching base of head, its groove wide with 

 sides parallel ; pronotum with sides deeply emarginate, form- 

 ing a rounded front lobe, hind margin trisinuate; scutellum 

 broadly triangular, its base nearly as wide as pronotum. Five
