spaced, microscopic tutjercles. Eye small, oval, length contained six times in 

 cheek. Pronotum decidedly shorter than dorsal surface of head, lateral mar- 

 gins parallel, transverse and longitudinal sulcus weakly defined, surface rather 

 thickly supplied with minute nodules and subtuberculate. Mesonotum with 

 surface thickly supplied with minute nodules, subtuberculate and feebly cari- 

 nulate, showing a faint medio-longitudinal carina. Metanotum similar with 

 a very faint lateral carinula on each side caudad, these continued on median 

 segment, the surface of which is similar. Mesopleura and metapleura nodose. 

 Dorsal abdominal segments longitudinally multicarinulate, the four median 

 carinulae increasing slightly in strength toward the caudal margin of each seg- 

 ment, this more marked on the second and sixth segments, slightly less decided 

 on third, on these three segments forming minute rounded crests at the caudal 

 margin. Eighth dorsal abdominal segment quadrate. Ninth (distal) dorsal 

 abdominal segment nearly twice as long as broad, moderate!}' convex in trans- 

 verse section with sides strongly convex; lateral margins parallel, suddenly 

 ascendant distad to the transverse caudal margin, which is minutely emar- 

 ginate mesad and as a result sub-bilobate; dorsal surface with a median 

 carinula whicli divides into two small carinulae proximad, laterad on each side 

 with a suj^plementary carinula, these are slightly convergent in proximal half, 

 thence straight, divergent to point where they round into the distal margin. 

 Mesosternum very feebly and irregularly carinulate and feebly nodulose: 

 metastermnn similar but more nearly smooth. Three proximal ventral al)- 

 dominal segments smooth, succeeding three segments longitudinally multi- 

 carinulate. Operculum elongate; ventral surface sharply defined from vertical 

 sides b}- a decided carina on each side, these carinae parallel l)ut disappearing 

 near apex of plate; ventral surface with a weak medio-longitudinal percurrent 

 carinula, this surface feebly convex pro.ximad, showing a weak swelling mesad, 

 deplanate distad; free margins of sides distad declivent, feebly convex, to 

 abruptly transver.se caudal margin, which is concave on each side, thus leaving 

 a brief triangular projection mesad hardly produced beyond the latero-caudal 

 angles. Limbs simijle, unarmed, the carinae very decided even tjn dorsal sur- 

 faces of tarsal joints. Cephalic femora strongly laminate, cephalic flexure 

 decided. Tarsal joints moderately elongate, metatarsus slighth' longer than 

 combined length of three succeeding joints, ventral surface heavily supplied 

 with delicate hairs, apices of four proximal joints occupied by moderately large 

 pulvilli. Large arolia present between the delicate tarsal claws.
