thick; second, third and fourth decreasing in length, the fourth 
quadrate; club-joints about equal in length except, for the longer 
apical joint, the second to fifth about twice as broad as long. 
Thorax above rugose-striate, irregularly so on the mesonotum 
and longitudinally so on the scutellum; tcgulse present, but wings 
entirely absent. Propodeum deeply emarginate medially to 
receive the elevated base of the first abdominal segment, faintly 
toothed at the sides of the emargination and at the posterior 
angles. Pleura shining; striate below, in front and along the 
sutures; smooth elsewhere. Abdomen above shining; first seg- 
ment rugose, second and third rugose-striate, the lines more or 
less longitudinal; fourth segment closely punctate; fifth con- 
fluently so; first segment as broad as long; second twice as long 
as the first, the width at apex greater than the length; third as 
long as the first and second together; distinctly broader than 
long; fourth to sixth decreasing in length, the fourth half as long 
as the third and equaling the apical ones together. Legs quite 
stout; tibial spurs very weak; tarsal claws simple. 
Type from Mt. Arthur, New Zealand (A. Philpott) Decem- 
ber 26, 1921, taken at an altitude of 4000 ft. 
This species resembles P. gracilipennis Dodd, from Australia, 
in the elongated first flagellar joint, but differs in the configuration 
of the other antennal joints, and is wingless. 
Family Belytid.® 
In 1889, Cameron described from Greymouth, New Zealand, 
the genus Betyla, and in 1892 Marshall proposed the genus 
Tanyzonus for a Belytid reared from the larvae of the remarkable 
New Zealand glow-worm, Bolitophila. Later in the same year, 
however, Marshall regarded Tanyzonus as synonomous with 
Betyla, believing the type species of both genera to be identical. 
In the material sent by Dr. Tillyard there are a number of 
specimens of Betyla-like insects representing three distinct 
genera; one of these is evidently Cameron’s Betyla, while the 
second and third are undescribed. In view of the fact that there 
are several closely related genera and species present in New
