width and the anterior margin but briefly; the pronotal disk is ap- 

 proximately as broad as long, the posterior margin very broadly 

 obtuse-angulate, the anterior margin sub truncate; the whole disk is 

 decidedly broader posteriorly and laterally distinctly deflexed. 



Tegmina noticeably exceeding the tip of the abdomen and apically 

 pointed; color of tegmina polished reddish brown, somewhat lighter 

 than the pronotal disk, the humeral areas pale yellowish; there are 

 over a dozen costal veins and about a dozen longitudinal discoidal 

 sectors; the anal area is rather long, about three times as long as the 

 greatest width. Wings in repose just reaching the tips of the teg- 

 mina, apically strongly sinuate; there are about a dozen slightly cla- 

 vate costal veins and the ulnar vein is bifurcate as previously men- 

 tioned, both branches directed to the apex of the wing. Figure 1 

 shows the venation of the wing. 



Abdomen blackish above, with lighter variations apically, the 

 basal portion light, as is also the ventral surface and the legs. Supra- 

 anal plate about as long as broad, apically rounded, a brief shoulder 

 formed on either side near 

 the base by an abrupt but 

 brief narrowing of the 

 plate at that point; cerci 

 long, exceeding the tip of 

 the supra-anal plate by 

 one-half their length and 

 comprising eight distinct 

 segments; subgenital 

 plate strongly asymmetri- 

 cal, the right half horizon- 

 tal and slightly convex, FJ«- 1--Wing of Blattella palmeei. new species. 



the lateral margin curved downward, the left side longer and ab- 

 ruptly turned up at right angles to a vertical position; closely fitting 

 into the angle thus formed is an outwardly rounded, somewhat 

 flattened organ with the inner margin forming a large, flattened 

 irregular-shaped flange bearing two bunches of several very long, 

 sharp, stout, spinelike bristles, those of the basal bunch directed 

 inwardly and those on the more apical bunch directed caudad; this 

 organ is a part of the concealed genitalia, though at a casual glance 

 it is easily mistaken for a part of the subgenital plate; the unique 

 specimen has not been dissected for the examination of the concealed 

 genital structures. Overlying the lateral margins of the third dorsal 

 segment of the abdomen preceding the supra-anal plate, and lying in 

 a lateral fold or depression in that segment, is an elongate, somewhat 

 club-shaped organ which arises near the median line and is directed 

 laterally and very slightly caudad, the tip rounded, very gently and
