HuTTON. — On New Zealand Stenopelmatidae. 227 



Length, 23mm. ; pronotum, 6mm. ; thorax, 12mm. 

 abdomen, 10mm. ; ovipositor, 10mm. ; fore tibia, 6mm. ; 

 hind tibia, 11mm. ; hind femur, 12mm. Width at mesonotum, 

 6mm. 



Localitij. — Banks Peninsula and the Chatham Islands. 

 Easily recognised by its thick hind tibiae. 



Talitropsis irregularis, sp. nov. Plate XII., fig. 9. 



Not so hairy as the other species. Anterior margin of pro- 

 notum projecting over the occiput ; inferior margins of the 

 lobes horizontal. Fore and mid femora each with one rather 

 long and weak colourless apical spine on the inner side ; hind 

 femora without apical spines, below with six minute spines on 

 the outer and seven or eight on the inner edge. Fore tibiae, 

 below, with two pairs of spines ; middle tibiae, below, with two 

 spines on posterior and one on the anterior side ; hind tibiae 

 with the superior apical spurs longer than in other species of 

 the genus ; above there are thirteen spines in each row, equal 

 in size and at regular distances. Second joint of the hind 

 tarsus more than half the length of the first. Supra-anal plate 

 short, concave at the apex. Supra-genital plate of male with 

 the lateral lobes irregular and almost blended with the central 

 lobe, which is broad and rounded at the apex, not keeled, 

 Cerci rather long. 



Colours. — Pale-tawny, variegated with brown ; fore and 

 middle tibiae with dark bands. 



Length, 12mm. ; pronotum, 3mm. ; thorax, 6mm. ; abdo- 

 men, 6mm. ; fore tibia, 6mm. ; hind tibia, 9mm. ; hind femur, 

 9mm. Width at mesonotum, 4mm. 



Locality. — Auckland, under bark. (Suter.) 



Described from a male ; the female is unknown. 



This species has apical spines on the fore and mid femora 

 like those of Pleioplectron, and from this alone it would be in- 

 cluded in the next group. But the apical spines of the fore 

 and middle tibiae, and the equal and equidistant spines on the 

 upper side of the hind tibias, keep it in Talitropsis. The sub- 

 genital plate of the male is also nearer that of Talitropsis than 

 that of Pleiopilectron. 



Genus Ischyroplecteon, gen. nov. 

 Size and form medium. Head perpendicular : antennae 

 short, slender, closely approximated but not touching at their 

 bases ; the first joint large, ilattened, rather longer than 

 broad ; the second shorter, slightly inflated in the middle ; the 

 third much longer, slightly inflated at the base ; the others 

 much shorter, cylindrical. Fastigium high, narrow, deeply 

 sulcated ; eyes semicircular, not prominent. Pronotum not 

 projecting much over the head. Metasternum with a blunt.
