interstices irregular, the third with a rather large tubercle 

 just before summit of posterior declivity, and another between 

 it and apex, fifth with a rather large tubercle, so placed 

 that with the two on the third they form an equilateral 

 triangle ; elsewhere with feeble tubercular swellings. 

 Abdo7nen with basal segment feebly convex. Legs compara- 

 tively short and stout; front coxae touching. Length, 5 mm. 



Hab. — Tasmania : Mount Wellington, in moss (A. M. 

 Lea). 



The type is probably a female. I have described it, 

 however, as its unusually dense clothing, and conspicuous 

 post-median tubercles, render it very distinct. 



The femora are distinctly ringed with whitish scales, 

 and the tubercles about the summit of the posterior declivity 

 are supplied with dark scales ; but otherwise there are no 

 distinct markings, the ochreous and grey obscurely running 

 into each other. 



Mandalotus incisus, Lea. 



Dr. Ferguson has taken at Blackheath (New South 

 Wales) some specimens that are in better condition and larger 

 (up to 6 \ mm.) than the types. They all have whitish rings 

 on the legs, dull-white spots at the sides of the abdomen, 

 and an ochreous spot at the middle of the base of the 

 pro thorax. 



Mandalotus severini, Lea. 



A well-marked specimen of this species was recently 

 taken from under a chip near the springs on Mount Wel- 

 lington. Its prothorax has several sooty spots on each side, 

 so disposed as to cause an appearance as of longitudinal 

 stripes, outside of which the clothing is more or less ochreous ; 

 there is also a small round dark spot on each side of the 

 middle. On the elytra many of the punctures are ringed 

 with white. The head and rostrum are feebly striped. The 

 apical half of the front tibise (as also those of the type) are 

 armed with some small teeth on their lower surface. 



Mandalotus sabulosus, Lea. 

 Recently taken by Mr. Carter at Eden (New South 

 Wales). 



Mandalotus niger, Lea. 



The male of this species has the inner edge of the hind 

 tibiae traversed by from 15 to 20 carinse ; rather feeble 

 towards the apex, but very pronounced towards the base. 

 From certain directions they are remarkably distinct; but 

 from most directions they are quite invisible.
