arT.17%. MONOPHLEBINAE AND MARGARODINAE—MORRISON. by 
distension of the derm, much more numerous than the pores over 
most of the body surface; spine measurements of this species in 
microns, as follows: Mid-dorsal, smallest 57, largest 82; mid-ventral, 
smallest 57, largest 86; marginal, largest, 178; without the lateral 
clusters of specialized spines of crawfordi; anal tube as in crawfordi; 
ventral cicatrices or clear pores in single irregular rows as in crawfordt. 
Larva.—Differing in no visible particulars from that of crawford.

In addition to the Maskell specimens, adult females from under 
bark of eucalyptus tree, Sydney, New South Wales, collected by 
George Compere under his No. 1049, have been examined. In these 
specimens, apparently due to the stretching of the derm, the crowded 
appearance of the dermal spines is much less conspicuous.
