1. Nysiits proyidus, sp. nov. 



Oblong, narrow ; greyish yellow, the upper surface more or less 

 clouded with fuscous, greyish pubescent. Head long, nearly as 

 wide between the front of the eyes as the width of the apex of 

 pronotum ; the surface closely pubescent, marked along the middle 

 with a slender, yellow, feebly raised line ; the surface between the 

 eyes granulated, the granules each side of middle arranged in lines, 

 punctures few, indistinct ; the tylus pale fulvous anteriorly, 

 bounded each side at base by a small knob placed next a dark band ; 

 middle of gula, including the bucculae, blackish piceous ; rostrum 

 slender, fusco-piceous or tinged with fuscous, reaching between 

 the posterior coxae ; antenna? dull testaceous, the base and inner 

 side of basal ioiut, base and apex of second, and base of fourth joint 

 blackish. Pronotum longer than wide, obscurely bilobed, impressed 

 and rather abruptly sinuated on the sides behind the anterior lobe ; 

 the surface transversely wrinkled, unevenly punctate with piceous, 

 less so on the anterior lobe, the apical border black ; the surface be- 

 fore the humerus spread with a blackish spot, which includes the 

 knob-like angle, but leaves a yellow spot next thereto ; the lateral 

 margin obsoletely carinate, indented before the anterior angle, the 

 middle with a pale yellow, slender line ; posterior margin a little 

 arched, sometimes bordered with black, having the posthumeral 

 border depressed, expanded, and pale yellow. Mesosternum black 

 in the middle, with the costal segment and the coxa tipped with

 Hemelytra dull whitish or testaceous, punctate with fuscous,

Length to tip of venter 3|-5 mm. ; width of pronotum 1-1 4 mm. 

 This is the common and widely distributed species which has 

 hitherto been wrongly referred to JV. scolopax, Say. The true N. 

 scolopax has a rostrum which reaches to the middle of the venter, 

 which is not the case in the species here described. Our species 

 inhabits North America from Quebec to Arizona, from thence it 

 spreads into Mexico and Central America, and following south it 

 is found on the Isthmus of Panama, and in Colombia and Northern 

 Brazil. In the AVest Indies it occurs in Trinidad, Grenada,
