crown, before and behind the eyes a large black spot ; underside 

 wholly ochreous. Antennce yellow-brown ; 1st joint piceous at base 

 and apex, 2nd at the apex only, 3rd and 4th joints darker than the 

 others. Eyes and ocelli brown or piceous. Bostrum yellow-brown, 

 a line on the outer side of the 2nd joint, and the apex of the 4th 

 pitchy-black. 



Thorax — Pronotum with fine, short, yellowish pubescence, especially 

 on the sides, convex, on the first two-thirds gradually, on the 

 remainder suddenly widened ; down the middle a black line, broad 

 on the narrow part, slender on the wide portion, on which also are 

 sometimes two indistinct fuscous streaks or clouds at each side of 

 the central line, but more often these are wanting ; sides of the 

 anterior portion, except the extreme margin, black. Scutellum 

 black, with a large wedge-shaped ochreous spot on each side. 

 Elytra pale ochreous, when developed as long as the abdomen ; 

 Corium with the nerves pale, more or less shaded with fuscous ; 

 Membrane with the nerves fuscous. "When the elytra are not 

 fully developed, as is generally the case, they reach less than half 

 the length of the abdomen, both the corium and membrane being 

 present, but abbreviated. In this state the colour is darker than 

 in fully-developed elytra. Sternum black in the middle and on 

 the sides, but on the latter the colour is interrupted with ochreous 

 on the presternum posteriorly. Legs very finely pubescent, 

 ochreous or light brownish, unicolorous ; thighs, inwardly on the 

 1st and 2nd pairs, with fine transverse black lines and an indis- 

 tinct row of dots, on the 3rd pair two rows of black dots ; tarsi 

 ochreous, the joints at the apex pitchy-black, sometimes the 1st 

 and 2nd joints of the 3rd pair entirely blackish ; claws black. 



Abdomen — above black, or broadly reddish down the middle, clothed with 

 very fine, short, silky, yellowish pubescence ; beneath, ochreous- 

 browu, smooth, shining, black or fuscous in the middle and on the 

 sides. Gonnexivum pale ochreous, narrow in the ($ , wide in the ? , 

 on the underside at times a longitudinal reddish streak. Genital 

 segments in the ^ , form a truncate apex by reason of the large 

 falcate processes ; in the 2 the apex is rounded oft' to a small obtuse 

 point. Length 3^ — 4 lines. 



Differs from N. pilosiolus in the lighter colour, in the absence of 

 the paleness on the anterior margin of the corium, in the elytra being- 

 usually short, in the legs being unicolorous, in the pilosity of the upper 

 surface of the abdomen, and in the form of the processes of the genital 

 segments, besides other minor characters.
