and about equal in lengtli. Legs long and slender; digitules 

 of claw and tarsus very long. 



I/ah. Pilar, Alto da Serra, and S. Paulo, State of S. Paulo. 



On the upperside of leaves of Brunfelsia sp. and Laurus sp. 



The first specimens were collected and sent to the museum 

 by Snr. Gustavo Edwall. 



Lecanium gracih, Hempel. 



Adult female asymmetrical, ovate, very flat, light yellowish 

 brown in colour; 3"50 millim. long, 2'50 millim. wide, and 

 •50 millim. high. Boiled in a solution of KOPI it stains the 

 liquid an amber colour. After boiling the dorsal derm 

 remains hard and opaque. It resembles the preceding species, 

 but the central portion of the derm is fused into one piece, 

 while around the margin there is a row of about twenty 

 sutures, indicating the division of the plates. A number of 

 fine hairs are scattered over the surface. There is also an 

 irregular longitudinal row of from eighteen to twenty-four 

 small round pores between the cephalic portion and the anal 

 plates. 



Antenn£e of six joints, variable in length, ranging from 

 •301 millim. to "354 millim. All the joints bear hairs. 

 Approximate formula : 3 (2 6) 1 4 5 or 3 2 6 1 4 5. Length 

 of segments: (1) 40, (2) 49, (3) 102-144, (4) 24, (5) 26, 

 (6) 51. Legs ordinary. Length of joints of first pair of 

 legs: coxa 102, femur and trochanter 178, tibia 129, tarsus 

 and claw 102. Digitules of claw large, with bulbous base 

 and ends widely expanded, twice the length of claw. Tarsal 

 digitules long, slender, with buttoned ends. Rostrum small, 

 situated between the first pair of legs. Rostral loop short, 

 extending halfway to the second pair of legs. Spiracles 

 small, with a single row of about thirty-six small round 

 spinnerets extending from the external openings to the margin 

 of the body. Anal cleft '730 millim. long, with the sides 

 contiguous. Anal ring apparently with ten hairs. Anal 

 plates small, triangular, with the outer angle slightly rounded 

 and the antero-lateral side longer than the postero- lateral. 

 Around the margin of the body there is a double row of fine 

 tuberculate hairs. The margin is slightly indented in the 

 stigmatal areas, and there bears a cluster of one long curved 

 blunt spine and two short ones. 



Larva (just hatched). — Elliptical, orange in colour, about 

 •450 millim. long. Antennae of six joints; joints 3 and 6 

 are about equal in length. Rostral loop not coiled, short, not 

 reaching to the anal plates. Tlie body terminates in two long
