succeeding joints pyriform, the longest about three times as long as 

 broad. Pronotum subquadrate; lateral margins cingulate and very 

 feebly diverging caudad, caudal angles more broadly rounded than 

 cephalic angles, caudal margin very weakly convex; prozona weakly 

 convex, metazona subdeplanate, very weakly convex caudad. Teg- 

 mina fully developed, nearly twice as long as pronotum; wings fully 

 developed, extending beyond tegmina distinctly more than pronotal 

 length, costal margin rounding broadly distad to sutural margin. 

 Dorsal abdominal segments with third showing very weakly devel- 

 oped stink glands, fourth with these glands slightly larger, eighth 

 and ninth segments feebly produced dorso-laterad with margin 

 there convex. Ultimate dorsal abdominal segment smooth, tri- 

 angularly weakly concave meso-distad, not three times as broad as 

 long, rectangular, with caudal margin truncate. Pygidium quadrate, 

 feebly declivent; surface in minute proximo-mesal area triangularly 

 feebly concave, thence feebly convex on each side, with surface 

 showing minute, scattered projections; lateral margins almost parallel, 

 with a few, minute median projections, very feebly convex to disto- 

 lateral angles, which are terminated by a small point; thence the 

 distal margin on each side is briefly very weakly oblique to small 

 rounded knobs, between which the median portion, comprehending 

 over half the distal margin, is feebly concave. Forceps much as in 

 arachidis, cylindrical, moderately flattened horizontally, but not as 

 much as in that species; shaft feebly convex, with ventro-internal 

 margin feebly lamellate to just beyond pygidium, this lamella there 

 terminating in a minute tooth, directed caudad, and with a similar 

 tooth, but perpendicular to the shaft, slightly more than half the 

 distance from the proximal tooth to the apex. Caudal metatarsus 

 appreciably longer than combined length of second and third tarsal 

 joints, ventral surface well supplied with hairs. 



Allotype: 9 ; same data as type. [Museum of Comparative 

 Zoology.] 



Agrees with type except in the following features. Pygidium much 

 as in this sex of arachidis, very briefly and broadly triangularly 

 deplanate proximad, thence with surface declivent and concave, 

 produced ventrad between the forceps in a small, subquadrate 

 projection, with disto-lateral angles produced in minute, conical 

 projections and ventral surface very feebly convex and rugulose. 

 Forceps straight to near apex, feebly triquetrous, enlarged at base, 

 thus embracing the pygidium, thence tapering to the moderately 

 incurved apices, with internal face and ventral margin supplied with 

 a few blunt tubercles.
