onserved. The margin of the body is but slightly 
incised at the stigmal areas, these latter being car- 
acterized by two short, thick spines, 35 microns 
long, and by.another curved spine, 55 microns long. 
The lateral margin of the body is ornamented with 
a double row of small, spine-like hairs, some longer, 
others shorter, the longest ones being about 50 mi- 
crons in length. The anal plates are small and tri- 
angular in shape, with the external angle rounded ; 
the interior side being 0.212 mm. long, the anterior- 
lateral 0.156 mm. and the posterior-lateral 0.125 mm. 
long The entire surface of the derm, on the dorsum, 
is full of glands, irregular, oval or nearly circular 
in from, and about 30 microns in diameter. 
Hab. Cantareira, near São Paulo, on the bark 
of canella poca and canella branca, two species of 
indigenous trees, where it was collected in October 
and November of 1919, by Mr. Ernest Schwebel. 
The type is incorporated in the collections of the

Mesolecaniwn uvicola n. sp. 
The adult female has the body elliptical in form 
and flat, light brown in color, with a yellow tinge. 
At the anterior extremity, near the margin, there 
is a small, circular, dark brown, eye spot, on each 
side. The derm is spotted with sinall dark spots, 
and on the dorsum there also are thin pieces of 
white ae The largest specimens were 6.250 mm. 
long, 2.750 mm. wide, and 1.250 mm. high. 
Boiled in a solution of KOH, the dorsal derm 
preserves it rigidness, but becomes transpareat and 
nearly colorless. The liquid becomes but slightly 
unged with yellow. The antennæ are iine, about 
0.362 mm. long, and are apparently composed of 
seven joints, that have the following lengths: (1), 
06; (2), 44; (3), 69-81; (4), 47; (5) 47-06; 
(6), 25; (7), 62. The approximate formula is:
