314 Transactions.- — Zoology. 



Antennae rather thick, with six joints. Margin bearing some 

 short blunt spines. Spiracular spines rather long. 



Male pupa covered by the usual white semi-glassy test 

 formed of polygonal plates. Length of test, about iV^- "^^^ 

 enclosed pupa is dark-reddish-brown. 



Adult male not observed. 



Hab. In Western Australia, on Niiytsia florih^mda. My 

 specimens were sent by Mr. Lea, from Walkaway. 



This species is allied to P. mashelli, var. spinosior, but 

 independently of its much smaller size it differs somewhat in 

 the feet, in the marginal spines, and in the dorsal elevation. 



Section LECANOCOCCIN^. 

 Genus Eriochiton. 

 Eriocliiton cajani, Maskell, 1891. 



This species, which I originally described in the " Indian 

 Museum Notes," vol. ii., No. 1, p. 61, has been sent to me by 

 Mr. Koebele, from Hongkong, on Mallotus cochin-chinensis. 

 He tells me that it is also common there on many trees. I 

 liave no doubt that it is widely spead in tropical oriental 

 countries. 



In 1891 I was not acquainted with the male ; but amongst 

 the specimens from China I have found several. The adult 

 male is dark-reddish-brown, rather large, reaching about ^-^in. 

 exclusive of the spike. Antennas of nine rather long joints, 

 the first globular, the rest slender, with several hairs on each. 

 Feet long ; tibia very long and slender ; claw very small ; 

 digitules fine hairs. Eyes : four dorsal and two ventral ; 

 ocelli two. Wings with rather strong nervure. Abdominal 

 spike slender, slightly curved, nearly as long as the abdomen. 



Section HEMICOCCIN^. 

 Subsection CEYPTOKEEMITID^. 

 Genus Mallophoba, gen. nov. 

 Adult females covered by a closely-felted secretion. In- 

 sects exhibiting an abdominal cleft and lobes. 



Male pupae in tests usually more waxy than those of the 

 females. 



Larvae naked, with prominent anal tubercles. 

 The sacs of this genus resemble those of Eriopeltis, 

 Philippia, or Signoretia ; but in those genera the larvae are 

 distinctly Lecanid, whereas here they are Coccid. 



Mallophora sinensis, sp. nov. Plate XXI, figs. 1, 2. 



Sac of adult female white, closely felted ; the form is pro- 

 perly sub-semiglobular, but many individuals are usually so
