subcircular, with the orange exuvia projecting at the an- 

 terior end. The male and female scales congregate in large 

 patches on the leaf, and even the area between them is 

 thinly covered with the silver}^ secretion. 



Female ver^' long and narrow, dark red, with the caudal 

 portion 3^ellowish; when boiled in liquor potassae becoming 

 dull yellowish, the caudal portion nearly colorless. The 

 body is chitinous, except the caudal and cephalic parts. 

 Sides of segments not protruding, the lateral margins 

 straight, except that just before the caudal portion there 

 is on each side a strong process, like the end of a finge% 

 directed backwards. This process is sometimes long, some- 

 times quite short, and just before it is a rudimentary 

 second process. No groups of circumgenital glands, but a 

 conspicuous row of transverse glands parallel with the 

 margin, as in M. mclnlciicac, but not so near the margin. 

 Four almost colorless lobes, and many pointed processes 

 of the margin. The median lobes resemble human incisor 

 teeth, but are shorter; the}/ are upright, well apart, with 

 a spine-like gland-hair in the interval. Be3Aond each median 

 lobe, not touching it, is a large pointed process of the 

 margin, just beyond which is the second lobe, which is 

 shaped like a cone l^'ing on its side, the apex adjacent to 

 the apex of the pointed process just mentioned. Next 

 comes a wide interval, with three small spine-like gland- 

 hairs; then a second large pointed process, resembling the 

 first; after which the margin is very coarsely serrate with 

 four or five pointed processes, directed caudad. Cephalic 

 end smooth. 



Embryonic larva (in bod}^ of female) with rostral filaments 

 in two coils. Two large figure-of-8 glands in the cephalic 

 region. 



Hah. — On upper side of large ovate-lanceolate leaves 

 of a forest tree; Campinas, Brazil. (F. Noack. n.° 12.) A 

 very distinct species; by its narrow scale with a colorless 

 border it resembles M. pallida Green, from Ceylon. 



Mesilla Park, New Mexico. U. S. A., June 8. 1898.
