Beneath these a number of chitinous plates and smaller projections occur in the 

 anal orifice, dextrad among which is found the process which we term the genital 

 hook in the species of Parcoblatta, here sharplj^ recurved, much paler in color than 

 the other chitinous processes, with recurved portion elongate, expanding slightly 

 distad throughout, with a ventral, oblique cleft just before the rounded, hooded 

 apex, giving the recur\ed portion a fanciful resemblance to a pitcher-plant. Sub- 

 genital plate con\ex, but with surface weakly concave at dextral portion of free 

 margin and at sinistro-mesal distal portion ; free margin dextrad rather decidedly 

 convex to mesal point, there an irregularly rounded, sinistro-mesal i)roduction 

 occupies half of the remaining distance to the sinistral cercus, the dextral margin of 

 this production forming, at its base, a rectangle with the dextral portion of the free 

 margin, remaining sinistral portion of free margin nearly straight, oblique, from base 

 of production to base of cercus. Dextral style situated mesad on production at its 

 apex, of same character as in riija; sinistral style also as in that species, situated 

 near sinistral base of production. I.imbs and armament of same normal for the 

 genus. 



Female. (Washington, District of Columbia.) Agrees with male except in the 

 following features. Size larger, form decidedly more robust. Eyes separated by 

 a decidedly greater space, slightly greater than that between the small ocellar spots, 

 which are situated in an area rounding gently into the plane of the interocellar space. 

 Pronotum without discal sulci. Tegmina subquadrate, with sutural margins attin- 

 gent, costal margin very weakly convex, rounding rather sharply into the very weakly 

 oblique, nearly transverse, distal margin, which shows a weak concavity toward 

 the apex of the anal vein, sutural margin similar to costal margin. Wings small 

 atrophied pads, their apices extending nearly to the distal margins of the tegmina. 

 Dorsal surface of abdomen unspecialized. Supra-anal plate not strongly trian- 

 gularly produced, with lateral margins very weakly concave, nearly straight, and 

 apex rather sharply rounded. Cerci slightly shorter and stouter than in male. 

 Subgenital plate convex, hardly produced, with free margin very broadh- and reg- 

 ularly convex.
