HuTTON. — On New Zealand Stenopelmatidae. 235- 



Pleioplectron diversum, sp. nov. Plate XIII., figs. 15-15i. 



Joints of the antennge cylindrical, closely covered with 

 hairs, the proximal joints longer than broad. All the thoracic 

 nota thickly margined. Legs hairy. All the femora unarmed 

 below. Fore femora with a pair of short apical spines ; those 

 on the middle femora longer than usual. Fore tibiae, below, 

 with two anterior (inner) and three posterior (outer) spines ; 

 none above. Middle tibiae, below, with three spines in each 

 row ; above, armed with a row of four spines. Hind tibiae 

 flattened above, with about twenty-five spines in each row, 

 irregular in size, some of them very small. First joint of the 

 hind tarsi considerably longer than the other three together ; 

 the third less than half the second. Subgenital plate of the 

 female with three points, the middle one projecting much 

 beyond the laterals. 



Colours. — Dark-brown, variegated with paler ; fore and 

 middle femora and all the tibiae transversely banded ; tarsi 

 of fore and middle legs tawny, those of the hind legs dark- 

 brown. 



Length, 17mm. ; pronotum, 4mm. ; thorax, 8mm. ; abdo- 

 men, 8mm. ; ovipositor, 12mm. ; fore tibia, 7mm. ; hind tibia, 

 15mm. ; hind femur, 13mm. Width at the mesonotum, 5mm. 



Localitrj. — Upper Wanganui (S. H. Drew). 



Described from a single female individual. 



The two spines on the fore femora of this species would 

 place it in Nconetus, but the apical spines of the fore and 

 middle tibiae, and the subgenital plate of the female, show that 

 it is nearer to Pleiojylectron. The spines on the upper surface 

 of the middle tibiae are very unusual. 



Genus Neonetus, Brunner. (1888.) 



Form small and stout. Head vertical. Fastigium rising 

 abruptly, slightly sulcate. Antennae long, rather slender, 

 closely approximated at their bases in the female, rather distant 

 in the male ; the first joint very broad, flattened, the rest 

 much shorter. Eyes large, semicircular, very prominent. 

 Pronotum rounded anteriorly and projecting over the head; 

 posterior margin straight. Legs moderate. Coxae of fore 

 legs spined. Fore and middle femora with a pair of acicular 

 apical spines ; hind femora without apical spines. Fore tibiae 

 ^vith a pair of inferior apical spines ; no superiors. Middle 

 tibiae with a pair of superior apical spines ; no inferiors. Hind 

 tibiae with two pairs of apical spines, the superior much longer 

 than the inferior. First and second joints of hind tarsi with a 

 pair of small apical spines. Cerci short and robust. Sub- 

 genital plate in the male long, boat-shaped, strongly keeled, 

 the styles inserted at the base of the plate. In the female it
