ica. The dextro-vcntral concealed genital plate is a smooth, some- 

 what convex, chitinous plate, from the inner side of which springs 

 a long, heavy, chitinous spike, directed toward the inner extremity 

 of the dextro-dorsal plate. 



The female of apacha, described by Saussure and Zehntncr'^*^'^ as 

 possibly immature, was in all probability adult. This sex of the 

 present species is very similar to females of erratica. The dorsal 

 surface is somewhat more hairy, with margin, particularly in 

 cephalic portion, bearing more and longer hairs. The limbs are 

 shorter and stouter, this particularly apparent in the tibiae. The 

 abdominal segments are unicolorous above and below, no trace 

 of spots being found as is frequent in erratica. It would be ill- 

 advised in our opinion, however, to attempt to determine uniciue 

 females of the species without attendant males, unless the student 

 has a first-hand knowledge of this sex of hoth. apacha and erratica.
