produced sinistrad, with disto-sinistral angle produced in a minute, delicate, 

 subquadrate plate; these three portions are separated by very deep and narrow 

 clefts, in depth about half the distance between their bases, at which bases are 

 situated the elongate, cylindrical styles, the sinistral as long as the sinistral 

 cleft, the dextral very slightly the longer, each with dorsal surface thickly 

 supplied with minute spines directed caudad and with apex very feebly enlarged 

 and incurved: Limbs very elongate and slender. Cephalic femora with 

 ventro-cephalic margin supplied with a series of slender, moderately elongate 

 spines, which decrease gradually in length and size to minute spinulae before 

 the two large and elongate distal spines, of which the more distal is the longest. 

 Tarsi extremely long, four proximal joints each suppUed with a small distal 

 pulvillus which is produced to an acute apex. Moderate arolia pre-sent. 

 Tarsal claw specialized'^; broad to near uncinate apex, with internal margin 

 of flange minutely serrulate, the three distal serrulations largest.'^

Agrees with male in form of head, maxillary palpi, microscopic nodes on 



tegmina, armament of limbs and specialization of tarsal claws. Pronotum more 



ample, surface showing moderate convexity. Tegmina and wings very much 



shorter, the veins all very much more weakly developed. Supra-anal plate 



triangularly produced, with apex strongly angulato-emarginate at an angle of 



somewhat less than ninety degrees. Subgenital plate scoop-shaped, the meso- 



distal portion not strongly produced; lateral margins broadly convex to near 



bases of cerci, there broadly concave, meso-distal portion with margin l)roadly 



convex.

'8 A differently specialized tarsal claw has recently been noted for the genus 

 Pledopiera. Hebard, Mem. Am. Ent. Soc, No. 2, p. 251, (1917). 



" This type of specialization is clearly a character of specific importance in 

 the present genus, but largely of degree, the differences in the various species 

 showing that it can not be used as a constant generic feature. , In Neoblattella 

 the highest specialization is noted in nahua and the genotype adfipersicollis, 

 in which the internal flange of the claw is heavih' .serrulate throughout; in 

 fasciata, conspersa and fraterna the serrulations are heavj- distad; in pellucida 

 moderate distad, while in fraterada and tilania they are subobsolete. In the 

 closely allied genus Cariblatta, the majority of the species show this flange with 

 serrulation of its margin subobsolete, but in punctipermis and imitans weak 

 distal serrulation of the internal margin of the flange is foimd, while in aedi- 

 culata it is decided. Species of the genera Eulhlaslohlatla, Aglaopteryx, Den- 

 droblaUa, Latiblattella, Supella and BlaUella have been examined and are found 

 to show no specialization of the tarsal claws.
