HuTTON.— rO?i Neio Zealand StenopelmatidaB. 231 



Locality. — New Zealand only. 



There is considerable confusion among the species of this 

 genus, if, indeed, there are more than one. I shall commence 

 with the only species that has been adequately described, and 

 then point out the characters which may possibly separate 

 the others from it. 



Pachyrhamma speluncae. Plate XIII., j3gs. 12-12c. 



Hemideina spelunccB, Colenso, Trans. N.Z. Inst., vol. xiv., 



p. 280 (1882). 



Fastigium rather low. Antennce long, nearly seven times 

 the length of the body ; basal joints cylindrical and nearly 

 glabrous towards the middle, gradually getting swollen distally, 

 and beyond the middle becoming cylindrical and hairy. In 

 the middle each joint is swollen a little below the apex, and 

 in many of the joints the lower side of this swelling bears 

 a short, blunt spine ; on the proximal half of the antenna 

 these spines are small or rudimentary ; near the middle, joints 

 bearing small spines alternate with joints bearing much larger 

 ones ; there are no spines on the distal portion. Inferior 

 margins of the lobes of the pronotum horizontal ; the prono- 

 tum and mesonotum distinctly margined. Fore femora, below 

 with a row of five spines on the anterior (inner) edge and none 

 on the posterior edge. Middle femora, below, with two or 

 three spines on each edge. Hind femora, below, with eight 

 spines on the posterior (inner) and three on the anterior 

 (outer) edge. Fore and middle tibiae, below, with four spines 

 in each row, and, in addition, the middle tibiae have, above, 

 four spines in an anterior and two in a posterior row. Hind 

 tibiae, above, with 36 spines in the inner and 41 in the outer 

 row ; these spines are distant in distal portion but smaller 

 and more crowded in the proximal portion of the tibia. The 

 superior pair of apical spurs are not half the length of the 

 first joint of the tarsus, and the middle pair are not half the 

 length of the superior pair ; all of them have numerous long 

 hairs. First joint of the hind tarsus not quite so long as 

 the other three together ; the third very short. In the fore 

 and middle tarsi the first joint is longer than the other three 

 together. Lobes of the abdominal terga with distant granula- 

 tions. Subgenital plate of male with a lanceolate projection 

 between the bases of the styles, which is strengthened by a 

 Y-shaped keel ; styles not projecting so far as the apex of the 

 plate. Cerci slei:ider. 



Colours. — Pale-tawny ; both borders of the pronotum and 

 the posterior borders of the mesonotum, metanotum, and 

 abdominal terga dark reddish-brown, the actual margins 

 being white. Distal portions of the femora dark reddish- 

 brown, with two white bands ; tarsi nearly white.
