IMandalotus scabkk, Lea. 

 In this species, of which I have seen but one male, thei'e 

 is a bhmt-tipped process, slightly longer than the trochanter, 

 projecting backwards from each of the miclclle coxas. 



Mandalotus AMPLi colli s, Lea. 

 In the original description of this species I spoke of the 

 depression on the abdomen being bounded behind by a dis- 

 tinct ridge on the second segment. The second segment, how- 

 ever, has not really a ridge, but has a small tubercle on each 

 side of its middle ; in the type these two tubercles (owing to 

 scales and a small amount of mud) appeared conjoined so 

 as to form a ridge, but on a second specimen being examined 

 their true nature was discerned. In the table given by me 

 (in Trans. Roy. Soc, S. Aust., 1907, pp. 131-135) it should 

 be placed in C ; and c should be altered to read : — 



Abdomen bituberculate.

Mandalotus niger. Lea. 

 Dr. E. W. Ferguson has recently taken the sexes of this 

 species on the Blue Mountains. The male has the intercoxal 

 process of the mesosternum laminated, and in my table the 

 species should be removed from E. r. to A. aa.: from the 

 two species (hoplosfefhus and shnulato?-) placed there it dif- 

 fers in being more than twice the size ; the process is shaped 

 somewhat as in suniiJafnr, except that it is flatter, but the 

 prothorax is larger in proportion, more rounded, and with 

 numerous flattened and rather conspicuous granules : the 

 front tibise are also without granules. In size and general 

 appearance the body, but not the limbs, approaches that of
