together, spur subulate with circular cross section, about half the length 

 of first tarsal joint. 



I have described the generic characters of this species as it differs in 

 some points from the type of the genus and approaches Onkclos Distant 

 in others ; unfortunately the shape of the antennae and of the spur of 

 the latter genus are not stated. 



Ochraceous-buff, face between eyes and the clypeus slightly darker, 

 antennae brown, carinae of pronotum, median portion of mesonotum and 

 carinae lighter ; a slight brown band on front coxae, and fainter ones on 

 first and second tibiae. Tegmina pale, veins concolorous or lighter, 

 thickly studded with brown granules bearing dark brown hairs. 



Genitalia of the same type as Asiraca. Anal segment large, lateral 

 edges turned ventrad so as to form a convexity on ventral surface, the 

 apical edge not turned ventrad and, together with the square emargina- 

 tion of the ventral edge of the pygophor, forming a five-sided ventral 

 opening ; styles subulate, widest and slightly flattened at base, curved, 

 bases and apices approximate. 



Length 2>-2> mm. ; tegmen 3.9 mm. 



9 Similar to the male. Lateral plates small, reaching less than one- 

 third from base, styles (ovipositor sheath) narrow, projecting well be- 

 yond pygophor, and slightly beyond anal segment, anal segment as long 

 as wide in ventral view, styles dark brown. 



Length 4.3 mm. ; tegmen 4.4 mm.

 Jnlv, 1014. Described from live males and five females in 

 good condition, and one broken female in the American Mn- 

 senm of IN^at. Hist., New York. 



Genns Neomalaxa nov. 



Head considerably narrower than thorax ; vertex prolonged well be- 

 yond eyes, broadest at base, apical two-thirds with sides parallel, length 

 1.6 times the width in middle; base of Y-shape carina obsolete leaving 

 a semiobsolete, quadrate areola near apex, basal half excavate, base 

 straight with carina ; length of face four times the width, sides parallel, 

 a simple median carina, sides carinate, an oblique carina from beneath 

 antennae to apical corner of face ; clypeus slightly wider than face, with 

 three subobsolete carinae, antennae long, slender, both joints terete, 

 reaching to be3^ond middle of clypeus, joints subequal in length, arista 

 apical, long. Pronotum shorter than vertex, hind margin slightly con- 

 cave, tricarinate, lateral carinae straight, diverging posteroirly, reaching I 

 hind margin ; mesonotum normal, tricarinate. Hind tibiae with one basal, 

 one median and seven or eight minute apical spines, hind tarsi «ubequal 

 in length to tibia, first joint longer than other two together, spur two- 

 thirds the length of the first tarsal joint, laminate, teciform, 14-16 small 

 teeth on hind margin. Tegmina large, radius not touching media, first 

 median sector joined to cubitus for a short distance near its base.
