We here describe a female taken at Lake Waccamaw, N. C, 

 September 8, 1911, by Rehn and Hebard and in the Hebard Col- 

 lection. 



Size medimii, form rather stout, head small but prominent and 

 wider than cephalic width of pronotum, interantennal projection 

 moderate. Eyes small but prominent, broad-ovate, proportionately 

 broader than in A^ fasciatus, moderately protruding. Maxillary 

 palpi of much the same form as in that species, but less attenuate. 

 Pronotum with length contained nearly one and two-fifths times in 

 width, narrowing very slightly cephalad, but more abruptly in cephalic 

 third; with a median impressed line more noticeable in the cephalic 

 portion. Tegmina^^ very slightly more than half as long as caudal

femur; longitudinal veins decided, not as conspicuous as in N. 

 confusus, cross-veinlets very faint. Wings absent. Ovipositor 

 slightly less than two-thirds the length of the caudal femur, distinctly 

 though feebly arcuate; apex of same narrowly sublanceolate, with 

 both dorsal and ventral margins armed, the former with heavy, 

 rather widely separated teeth, the latter with minute very widely 

 spaced serrulations. Limbs delicate, spines of caudal tibia? rather 

 slender. 



We here describe a male bearing the same data as the female 

 described above. 



Slightly smaller but proportionately broader, particularly in the 

 abdominal portion. Tegmina transparent and delicate, very broad 

 and completely enveloping all but the ventral surface of the pecu- 

 liarly broadened abdomen; when in repose the dorsal fields are very 

 flat and hemi-elliptical in outline, the lateral margins slightly bowed, 

 subparallel. Wings absent. The ventral segments of the abdomen 

 are extremely broadened and extend outward and upward on the 

 sides of the abdomen above the normal dorsal segments, thus making 

 the abdomen unusually broad and its entire dorsal surface deeply 

 concave. 



60 The form of the female tegmina is useless as a character in the present species 

 owing to its variabiUty. We have before us brachypterous specimens ranging 

 from those which have the distal margins of the dorsal field transverse, to those 

 which have these margins decidedly oblique, the degree of angulation of the 

 tegmina also varying considerably.
