HuTTON. — On Neiu Zealand Stenopelmatidse. 221 



spines. It is, however, much larger, and has different colours. 

 The length is 57mm. ; of ovipositor, 19mm. ; of hind tibia, 

 38mm. ; of hind femur, 38mm. The colours are pale reddish- 

 brown, with the head and edges of the pronotum dark. 



Locality. — Mountainous districts of Nelson. Living in 

 holes which it bores in the trunks of trees. 



Genus Onosandkus, Stall. (1878.) 



Size moderate. Head small, the fastigium broad, flattened 

 or rounded. Antennae with the first joint thick, longer than 

 broad ; second joint shorter, not swollen ; third joint about 

 twice as long as the second ; the rest small. Pronotum longer 

 than broad, more than half the length of the thorax, narrowed 

 anteriorly. Mesosternum and metasternum deeply bilobed. 

 Legs medium ; coxse of fore and middle pairs spined ; femora 

 unarmed, those of the hind legs much dilated, continuously 

 rounded above near the insertion, slightly sulcate below. Fore 

 and mid tibiae with two pairs of apical spines. Fore tibiae 

 without auditory pits. Hind tibiaa with three pairs of apical 

 spines, of which the inferior are the shortest and the superior 

 the longest; those on the inner side are as long as the first joint 

 of the tarsus ; those on the outer side are shorter ; above the 

 tibiae are rounded with two rows of short spines terminated by 

 a subapical pair as long as the superior apicals. Pads on the 

 tarsi well developed ; none of the joints spined ; fourth joint 

 shorter than the other three together. Supra-anal plate trun- 

 cated. Cerci moderate. Subgenital plate of the male trans- 

 verse, the apex between the insertion of the styles straight or 

 slightly hollowed ; the lobes carrying the styles not prominent. 

 In the female the subgenital plate is triangular, the apex 

 sharply pointed. The ovipositor is much compressed. 



There is no sounding-file like that in Hemideina, but the 

 ends of the terga of the first to the sixth abdominal segments 

 are roughened, and these may serve as a sounding-organ. 



Localities. — New Zealand, India, and Africa. 



Stall established this genus in 1878 ; it appears to be 

 identical with Lihariasa, of Walker, which was made in 1869.
