large, and around the external orifice of each are clustered 

 several hundred round spi?\neret3 and a few smaller tubular 

 spinnerets. The ventral surface of the abdomen is divided 

 into segments by transverse furrows and the posterior part is 

 thickly set with round spinnerets. The anal |)lates are small, 

 the postero-lateral side is convex and as long as the antero- 

 lateral. Around the lateral margin tliere is a row of minute 

 hairs set far apart. The dorsal derm is thickly set with 

 small tubular glands. 



Hah. On an unidentified forest-bush on the banks of the 

 Rio Mogy-guassu, near Itapira, State of Stio Paulo. Rare. 



Lecanium campomanesice, Hempel. 



Adult female elliptical, sliiny, very convex, 7*5 millim. 

 long, 5 millim. wide, and 4 millim. high. Anal cleft 2 millim. 

 long, sides not contiguous. The dorsum is creamy white, 

 spotted with a number of small, irregular, dark olive- green 

 spots, and with four irregular longitudinal furrows formed by 

 a number of gland-pits. The derm is not very hard and is 

 wrinkled and pitted by gland-pits. Beneath it is concave, 

 light yellow, and with two prominent chalky lines on each 

 side. Boiled in a solution of KOH it colours the liquid ligiit 

 brown. The derm becomes soft and transparent, but shows 

 a number of small, dark, subcircular spots. 



Antennse variable, usually of eight joints, although some- 

 times but seven joints are present. Length about '500 millim. 

 All joints except 3 and 4 bear hairs. A|)proximate formula: 

 3 (2 1) 8 (4 5) (6 7) or 3(2 1) (8 4 3) CG 7). Length of 

 joints: (1) 76, (2) 76, (S) 89, (4) 55, (5) 65, (6) 35, (7) 35, 

 (8)57. Legs ordinary ; coxa with several hairs and about 

 four short spines; trochanter with two short spines and one 

 long apical hair; tibia longer than tarsus. Tarsal digitules 

 long, slender, with expanded ends; digitules of claw large 

 and thick, ends flattened and expanded. All the digitules 

 extend far beyond the tip of claw. Length of joints of first 

 pair o£ legs : coxa 186, femur with trochanter 267, tibia 191, 

 tarsus and claw 142. Rostrum well developed, situated 

 between the first pair of legs. Mentum large, with eight 

 hairs near the tip. Rostral loop short. Spiracles large, with 

 the exterior orifice greatly expanded and flattened. Many 

 small rouiid spinnerets are grouped about the spiracles. 

 Anal ring apjjarently with eight liairs, one being found with 

 nine hairs. Anal plates small, triangular, with . tiie antero- 

 lateral side longer than the postero-lateral. Tliere is a double 

 row of shoit hairs around the lateral margin of the body. 

 'Ihe sligmatal areas are characterized by groups of three 

 large blunt spines, one of which is longer than the others,
