the length of the same; cephalic portion of the lateral margins less 

 diverging, oblique subtruncate, lateral angles very blunt, the margins 

 regularly arcuate mesad thence to the point of least width, lateral 

 margins finely crenulate-serrulate; caudal portion of the 

 pronotum ^vith broadly rounded margins which are sub- //)V 

 truncate mesad, entire; transverse sulcus woll impressed; ia^-j-^*) 

 caudal transverse depression less impressed than the trans- 

 verse sulcus and not quite as evident as in liheriana; when 

 viewed from the side the dorsal outline is lower and more fiq. io.-Pa- 

 undulate than arcuate as in liheriana, central portion of nurqica 

 collar similarly compressed but less decided; rectangulate l^. dor- 

 section of lateral margins similar to liheriana. Tegmina ^^ o^'^- 

 and wings as in liheriana. Abdominal segments non-lobate prokotum 

 laterad; supraanal plate transverse, margin slightly con- of type. 

 cave over the cerci, apex rounded; cerci and subgenital 

 plate much as inlihcjiana. Cephalic limbs much as in the preceding 

 species, but more slender; femora with ventro-internal margin armed 

 with tliirteen spines usually alternating in size; tibiae with thirteen 

 external and internal spines. Median and caudal limbs 

 similar to those of liheriana but the pregenicular femo- 

 ral lobes are lower.

 of the middle; internal face of the cephalic coxa? and femora wood

In addition to the type we have before us a paraty]iic male, wliich 

 is very slightly smaller than the typical individual but otherwise 

 identical. 



The presence of a third species of this genus at ^fount Coffee is 

 nulicated by an additional broken specimen (R. P. Currie, 1897), 

 minus head and most of the limbs.
