A specimen sent by Mr. Froggatt agrees with this species in 

 all details except as regards the clothing of the front, which is a 

 dark brown colour, yellowish between the sub- and frontal calli, 

 frontal callus shining black, about two-thirds the width of the 

 front, upper edge oval, no lineal extension, its base a short dis- 

 tance from the subcallus, the latter with a shallow median 

 groove: ocelli prominent, with grey tomentum round them as in 

 the type. 



The third joint of the antenna? and the palpi are broken off. 



A second specimen also appears to represent this species, but 

 both the thorax and the abdomen are somewhat denuded: there 

 is scarcely any trace of spots on the abdomen, and the stripes on 

 the thorax are indistinct, otherwise it is typical 



Hab.— N.S.W.: Hay, Moree (W. W. Froggatt, Nos.72, 74F). 



The specimen from Hay was taken on the trunks of red-gums 

 (Eucalyptus sp.) on the banks of the Murrumbidgee River; the 

 one from Moree was taken by sweeping grass on marsh-land.
