Hemideina armiger. 



Deinacrida armigcr, Colenso, Trans. N.Z. Inst., vol. xvii., 

 p. 155 (1885). Hemideina nitens, Colenso, I.e., vol. xxi., 

 p. 193 (1889). 



The head in the male is large, but narrower than in H, 

 megacepJiala, to which it is closely allied. The fastigium is 

 narrow and the fovea obsolete. The gense are more rugose 

 than in H. megacepJiala, and the front of the epicranium, as 

 well as the post-clypeus, is transversely wrinkled. The frontal 

 keels are curved outwards and rugose. The male has a deep 

 depression under each antenna, and a transverse ridge across 

 the clypeus. The labrum is ovate, and the mandibles are not 

 conspicuously keeled in front. The spines on the femora and 

 on the fore and middle tibiae are the same as in H. mega- 

 cejyhala. Hind tibiae, above, have three spines in the outer 

 and four in the inner row, the spines being longer than in H. 

 megacepJiala ; belov7 there are a pair of subapical spines, fol- 

 lowed by two single spines. 



The subgenital plate in the male is like that in H. mega- 

 cepJiala, but in the female it is slightly truncated, not notched, 

 at the apex. 



Colours. — The pronotum is pale, with dark markings in 

 the depressions. The abdominal segments, above, are banded 

 anteriorly and posteriorly with brown, paler than in H. mega- 

 cepJiala. There is no longitudinal dorsal dark band in either 

 sex. The female is darker in colour than the male. 



Length, dOmm.; of head, 25mm. $, 11mm. 2; of pro- 

 notum, 6mm. ; of thorax, 13mm. ; of abdomen, 24mm. ; of ovi- 

 positor, 19mm. ; of fore tibia, 15mm. ; of hind tibia, 25mm. ; 

 of hind femora, 22mm. Width of head, 11mm. S , 8mm. 5 ; 

 of pronotum, 9mm. 



Localities. — Wairoa and Forty-mile Bush, in Hawke's 

 Bay ; Manawatu, in Wellington Provincial District. 



I have examined four males and three females, including 

 the Eev. W. Colenso's types, and find the characters to be 

 constant.

A female in the Museum has the fastigial fovea elongate ; 

 slight depressions under the antennae ; the frontal ridges 

 straight and low ; the labrum slightly ovate. The fore and 

 middle femora have no spines below ; the hind femur has two 

 strong spines followed by some minute ones on the outer 

 edge. The fore and middle tibiaB have each two pairs of 

 apical spines, and none above ; below the fore tibiae have
