ratio) distal spines. Other ventral margins of femora furnished 

 with not numerous, heavy, elongate spines. Median and caudal 

 femora, in addition, supplied with a single, elongate, 'heavy genicu- 

 lar spine. Pulvilli as in Parcohkitta. Small arolia present. 



All of the species of this genus known to us are pale in general 

 coloration ; buffy, in some species moderately to strongly tinged 

 with ochraceous. Distinctive characters of coloration are en- 

 tirely lacking in nearly all of the forms.

The characters given above to separate the present genus from 

 Ischnoptera and ParcoblaUa, readily separate males of the present 

 species from those of any other found over the regions at present 

 under consideration. In the present genus this species is anoma- 

 lous in the males having the median segment unspecialized and the 

 supra-anal plate, subgenital plate and styles of an entirely dif- 

 ferent type from those of the males of the other species of the 

 genus. 



In the female the tegmina are decidedly reduced, subquadrate, 

 with characters of venation obliterated; thus differing widely 

 from the other known species of the genus, the females of all of 

 which have the tegmina fully developed. This tegminal reduc- 

 tion in the present species gives females a distinct, though super- 

 ficial, resemblance to females of Parcoblatta virginica.

 [Hebard Collection, Type Xo. 423.] 



Description of Type. — Very similar in general structure to 5. jamaicana, size 

 medium small, slightly larger than in that species; form moderateK' slender, as in 

 jamaicana; slightly more slender than in .S". capitata. Head with eyes large, larger 

 than in jamaicana or capitata. Interocular space three-fifths as wide as inter- 

 ocellar space. Ocelli distinct, with surfaces flat and almost perpendicular to the 

 plane of the interocellar area, their margins there shar])K- rounded. Maxiliar\- 

 palpi with third and fifth (distal) joints subequal in length, fourth joint slightly 

 shorter. Pronotum of same form as in capitata but proportionately deeper. Teg- 

 mina and wings fully developed, as given in generic description, structure of same 

 very delicate. Median segment unspecialized. Sixth dorsal abdominal segment 

 with two moderately deep, small, meso-proximal depressions, between which it is
