BLATTELLA Caudell. 

 Blattella dilatata Saussure- 



Palmerlee (Schaeffer), 1 9 . Huachiica Mountains (Schaeffer)^ 

 July 8,16". 



The female specimen agrees very well with the description of this 

 species, which has been recorded only from Orizaba, Mexico. The 

 male, which has never been described, resembles Blattella adspersicol- 

 lis, having the slight maculations of the pronotum very similar, but is 

 slenderer with the pronotum more trigonal, the margins of the same 

 more deflected and the tegmina shorter and broader. The measure- 

 ments of the pair are as follows : 



& 9 



Length of body, 12. mm. 13.5 mm. 



Length of pronotum, 3.5 " 3.9 " 



Greatest width of pronotum, 4.6 " 5.5 " 



Length of tegmen, 14 " 8.5 " 



Greatest width of tegmen, 4 " 3.8 " 



In the female specimen the tegmina do not reach to the apex of the 

 abdomen, which they exceeded in the type, but the form of supra- 

 anal plate and other characters are very similar to those mentioned by 

 Saussure. 



MANTID^. 



YERSINIA Saussure. 

 Yersinia solitaria Scudder- 



Carr Canyon, Huachuca Mountains, August (Skinner), 2 6^. Sep- 

 tember and October (Beiderman), 3 ? . 



All of these specimens are larger than a female from Gallinas Canj'on, 

 New Mexico, and no traces of organs of flight are present. A very 

 curious feature about this species is the distinct proximal inflation of 

 the caudal femora, probably a sign of considerable saltatorial ability. 



LITANEUTRIA Saussure. 

 Litanentria skinneri n. sp. 



Types: c^ and 9 ; Carr Canyon, Huachuca Mountains, Cochise Co., 

 Arizona. August, 1905 (H. Skinner). [A. N. S. Phila.] 



Differing from the known members of the genus in having the teg- 

 mina and wings of the male short as in the known females of the genus. 



Size about the average for the genus. Head distinctly trigonal when 

 viewed cephalad, dorsal outhne straight in the male, slightly arcuate in 

 the female ; facial scutellum transverse, slightly arched in the male, oblong
