Mr. A. Ilcnipel on Brazilian Coccidaa. AS? 



Size of tlic larf:;cst individuals: — Length 11 niillini,, ^vidtll 

 8*25 miiliiu., lieiglit 8 niillim. The wax is hard and i^rittle 

 and is distinctly divided into seven plates, of which the 

 dorsal plate is the largest. One small, elliptical, dark- 

 coloured nucleus is situated in the centre of the dorsal |)Iatc . 

 Ko other nuclei are })res(Mit, 'Ihe suiface is roughened by 

 Cinicentric rings and slight lateral hiinips. Two white chalky 

 lines are present on the ventral surface, but do not appear on 

 the sides. 



The adult female denuded of wax is 6'5 millim. long, 

 4'5 millim. wide, and 4 millim. high, with a slight notch on 

 the margin at each stiguiatal area, but without any distinct 

 humps. The derm is liglit brown, thin, and chitinized. The 

 caudal horn is light brown, 2 millim. long, and placed hori- 

 zontall}'. Boiled in a solution of KOll the licpiid becomes 

 tuibid and of an orange colour with a pinkish tinge. The 

 dorsal derm remains hard, while the ventral derm is soft. 



The antennre are of eight joints, all except joints 3 and 4 

 bearing hairs. Length about "380 millim. Length of the 

 joints: (1) Q6, (2) 53-66, (3) 66-'<0, (4) 35-40, (5) 57-66, 

 (6) 26, (7) 26, (8) 40. Approximate formula: (3 1 2 5) 

 (8 4) (6 7). Legs ordinary, short. Length of joints : 

 coxa 111, femur and trochanter 222, tibia 147, tarsus 79, 

 claw 24, digitules of claw 40. Tarsal digitules tine, slightly 

 longer than the digitules of claw, with the ends slightly ex- 

 panded. Digitules of claw large, with widely expanded ends. 

 Around the lateral margin of the body there is a thickly set 

 row of short, sharp, conical spines. About each stigmatal area 

 there is a group of fifty or more larger conical s()ines. The 

 derm of both suifaces bears many small glands. 



Jlab Maiulos, State of Amazonas. Presumably on an 

 uncultivated shrub or tree. 



Ceroplastes grandis, Ilcmpel. 



Adult female scale very large, ovate, truncated and slightly 

 excavated posteiiorly, acuminate anterimdy. Dorsum very 

 convex, coming to a point at the dorsal imcleus. The wax is 

 very soft, containing much water, aiul has a characteristic 

 pungent smell. It is white on the dorsum, turning to a 

 salmon-pink on the sides and lower edge, and is distinctly 

 divided into plates. Nuclei brown, the lateral ones not con- 

 spicuous. The surface is shiny and uneven, being depressed 

 abuut the nuclei and caudal horn and slightly elevated on 

 the other parts. Size of the largest specimens: — Length 

 18 millim.; width 14 millim.; height 11 millim.
