Os escudos das fêmeas e dos machos, agrupados no lado 

 inferior das folhas, são cobertos com uma camada muito fina 

 de secreção branca, que dá á folha a apparencia de ser prateada. 



Pseudoparlatoria argentata n. sp. 



The female scale is circular to subcircular in outline, slightly 

 flattened at the anterior margin, and about 1.226 mm in diameter. 

 The scale is hard, flat, black, with an excentric circle and a mar- 

 ginal area transparent. The pellicles are marginal ; the first is 

 small and light yellow in color, the second is large, with à 

 transparent margin, and the remainder forming a black, tri- 

 angular spot. The male scale is slightly smaller than that of 

 the female, and also more elongate, being from 0,612 to 

 0,7°0 mm. long. This scale is not black, but consists of the 

 yellow pellicle situated in the central elevated area and the 

 marginal area which is nearly transparent. 



The adult female is subcircular in outline, having a 

 diameter of about 0,525 mm. but there are some individuals 

 that have a diameter of 0,717 mm. The body is light yellow 

 in color or white, with the posterior margin rounded, having 

 three pair of very short lobes on the pygidium, of which the 

 median pair is wide and simple, and the second and third 

 pairs are deeply incised. Between the two median lobes there 

 is one pair of simple plates ; between this and the second 

 pair there is a plate that is incised ; and between the second 

 and third pair there is a simple plate. The margin of the 

 pygidium cephalad of the lobes, is thick hard and finely 

 dentated. The three segments of the body cephalad of the 

 pygidium, have the lateral margin modified into large lobes. 



The pygidium contains numerous circular glands, others 

 transverse, and still others linear. There are usually five 

 groups of circumgenital glands ; of which the anterior-laterals 

 vary from 12 to 19, the posterior-laterals from 14 to 25, 

 and the median group from 1 to 4. In some specimens the 

 median group is wanting. 



The male is small, dark brow in color, with the antennae 

 and the legs lighter. The body is 0,210 mm. wide and 

 0,612 mm. long, including the style. The eyes are large and 

 black. The antennae have ten joints. The wings are 0,647 

 mm. long and are transparent. 



The newly hatched larvae have the body elliptical, fat, 

 and yellowish white in color, with two short terminal hairs.
