ENTOMOLOGY.’ 
Two New Species of Lecanium from Brazil.—Lecanium 
reticulatum, n.sp., 2 scale long. 11, lat. 5, alt.3 mm. Smooth, ridge- 
less, shiny, dark brown, rather inconspicuously spotted with whitish. 
These whitish spots are not dermal, but consist of small patches of 
waxy secretion, which can easily be scraped off. Posterior incision 
3 mm. long. 
Derm very strongly reticulate, reticulations large, 3,4, 5 or 6-sided, 
each with a large oval gland-spot, placed more or less to one side. 
Walls of reticulations very thick. This reticulation of the derm is 
easily seen with a lens. 
Legs brown, ordinary. Coxa with two hairs at one end,one very 
long ; tibia a little less than one-third shorter than femur; tarsus 
about one-quarter shorter than tibia. 
Tarsal digitules very long, slender, with only moderate knobs, which 
dilate rather gradually. 
Claw short, stout, curved. Digitules of claw small, but extending 
considerably beyond tip of claw, one larger than the other, stout, with 
only moderate knobs. 
Removed from the bark the insect leaves a patch of white secre- 
tion. 
.A parasitised specimen is only 8 mm. long, and is yellowish-brown, 
with the reticulation black, very conspicuous with a lens; margin 
blackish. The parasite must have been a large one, the single hole 
being over 1 mm. diameter. 
Hab., on twigs of an unidentified woody plant, Sao Paulo, Brazil 
(Dr. H. Von Ihering). 
Three were sent, one spoiled by a parasite, the other two in good 
condition. One of the latter I boiled in caustic alkali, but was not 
able to obtain all the desirable details from it. The imperfection of 
the description does not particularly matter, since the species is very 
easily recognized. Itis closely allied to L. depressum, Targ., but differs 
in its very much greater size. 
Lecanium baccharidis, n.sp., 2 scale long. 44, lat. 24, alt. 1} mm. 
Dark brown, becoming eventually whitish-brown froma waxy or cot- 
tony material scattered over the surface. Where one scale overlapped 
another, the portion covered is bright orange-yellow with a greenish
