Four new Reduviidae. 



BY NATHAN BANKS. 



Of the four species described below, two have been in my 

 collection for years and are taken in the Eastern States, the 

 other two are from Arizona and sent in recent years by Mr. 

 Biederman. 



Pnirontis modesta n. sp. 



Pale greyish yellow, with a faint median dark line on the pronotum, 

 four black dots on each lateral margin of the venter and sometimes 

 a black spot in front of each eye. Four large spines under femur I, 

 the basal one short, the next about as long as width of the joint, third 

 still longer, and fourth the longest ; the third is a little nearer to the 

 fourth than to the second ; tibia I has on the inner side three long 

 spines (closer together than in Pn. languida) and near the last one on 

 the lower side is a long, erect, stout spur or spine. Tip of abdomen 

 forked as in Pn. languida, but the lobes are more divaricate and broad- 

 er at the tips than in that species. Length 11 mm. 



From Falls Church, Va., and Glencarlyn, Va., in June and 

 July. Resembles Pn. languida, but is smaller, and readily 

 separated by the longer spines on femur I, and the long spur 

 on tibia I. 



Spiniger arizonica n. sp. 



Shining deep black ; the posterior margin of the pronotum narrowly 

 reddish, broader at the humeri, and from thence extends inwards and 

 forwards a narrow red line to the transverse furrow, lower lateral 

 margin narrowly reddish, lateral ends of the collar also reddish, scutel- 

 lar spine mostly reddish ; dorsum of abdomen red, a black spot at apex 

 of each segment on the connexivium ; venter black, with a broad median 

 red stripe reaching to middle of the penultimate segment, and the 

 lateral margins rather broadly red, almost interrupted with black on 

 the apical third of most of the segments. Anterior lobe of the prono- 

 tum smooth, a deep median groove, and two grooves each side reaching 

 only one-half way forward. Posterior lobe depressed on middle basal 

 part, and here strongly, transversely rugose, growing weaker behind ; 

 humeri moderately prominent, right-angled; the scutellum margined, 

 spine cylindrical oblique, and nearly as long as the scutellum; meso and 

 metapleura vertically, coarsely striate ; in front and rather between 

 bases of antenna? are two short, slightly divergent ridges; legs and 

 antennae all finely, densely hairy; ventral segments of abdomen finely 

 transversely striate ; male genital lobe smooth on sides, hairy below 

 and behind, rounded, with a slight apical swelling containing a median
