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; tegulse 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. Pleune 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 larvse of the remarkable 

 New Zealand glow-worm, BoHtophila. 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
