202 THE CANADIAN ENTOMOLOGIST. 



seem somewhat related to the Eidecanium series, which inhabits the 

 Paltearctic and Nearctic regions, and is entirely absent (except where 

 introduced on cultivated plants) in the Neotropical and x\ustralian. Now 

 that the Neotropical series is increased to four, we can see (i) that it is 

 diversiiied within its own limits, doubtless actually more numerous in 

 species than present information shows, and probably, therefore, endemic; 

 (2) that it more resembles the Australian species than those of the 

 Palsearctic or Nearctic regions. 



Thus the indications are, that the Palfearctic-Nearctic series of 

 subglobular forms is altogether distinct from the Neotropical-Australian 

 series, the resemblance being much closer superficially than in structural 

 characters. The last-mentioned series does, however, seem to hold 

 naturally together, and its distribution may, perhaps, be used as an 

 argument by those who favour the hypothesis of land-connection between 

 S. America and Australia. 



The ihree new Neotropical species were all collected by Dr. Von 

 Ihering, the well-known naturalist, now of the Sao Paulo Museum. 



Lecanium psetcdosemen, sp. nov. 



5. Scale globose, max. diam., about 10 mm., a moderate-sized 

 specimen is long. 85^, lat. 7^^, alt. 7 mm. Scale clasping twig; leaving, 

 when removed, four small, broad stripes of white secretion. Colour 

 coffee-brown, or reddish-brown, sometimes irregularly marked with 

 yellowish ; surface smooth, fairly shiny. Under a lens appears minutely 

 tuberculose and finely and closely spotted with yellowish. 



Boiled in caustic soda, it stains the liquid madder-brown, the pigment 

 precipitating on standing. 



Dermis (transmitted light) not tessellated ; shows large, oval gland- 

 pores. 



Claw rather short, stout, curved, sharply pointed. Digitules of claw- 

 extending beyond its tip, rather slender, but with large knobs. Tarsal 

 digitules only moderately long, slender, with small knobs. Tarsus some- 

 what arched ; tibia also somewhat arched, but in a contrary (forward) 

 direction ; both slender, tibia about j^ longer than tarsus. Femur about 

 as long as tibia, moderately stout. Trochanter with a very long hair at 

 its end,
