From the above data it is evident the species is rather widely 

 distributed at moderate elevations in the central mountain and 

 table-land region of Costa Rica. 



The features of variation which are evident from the series are: 

 size variation, which is demonstrated by the table of measure- 

 ments given above; the width of the face and the interocular 

 region, which latter, especially in the male sex, is slightly narrower 

 or distinctly broader than described above, the maximum width 

 l)oing in the male paratype from Santa Maria de Dota, in which 

 the width between the eyes is appreciably greater than the depth 

 of the face from the occiput to the ch'peal suture, the whole 

 head being broader than average and correlated with an unusually 

 wide pronotum; caudo-lateral production of the disto-dorsal 

 abdominal segments, which in the female sex show appreciable 

 variation, in one of the La Palma females these being so sharply 

 produced as to be sub-spinifonu: coloi' fluctuations, described 

 above.
