but sparser further forward; two minute prickles on hind border of 
temple, a hair inside the border, and two pairs on the occiput. Pro¬ 
thorax with five short spines on each shoulder; one behind each end of 
the inter-scapular bar; three spines, a hair, and a spine on each side 
anteriorly; and a row of ten hairs along the hind margin. Mesothorax 
with a pair of nunute spines, one on each side of the middle fine. Meta¬ 
thorax with a group of four spines inside the antero-lateral angle; a 
row of seven similar spines, projecting backwards, not outwards, on 
each lateral border; hind border with two hairs and a spine on each 
side, and a row of twelve hairs between them. Abdomen with a few 
spines and one to three hairs in each angle; the first segment with a 
fine hair inside each antero-lateral angle; all segments to the eighth 
with a row of alternating long and short hairs, the short hairs being in 
pairs in the median area. On the ventral surface there are two rows 
of hairs on each segment except the first. On the third and fourth 
segments the posterior row is broken at each side by a comb-like group 
of short spines, longer on the third than on the fourth segment. 
Chaetotaxy of Differs only in the terminal segments of the 
abdomen, the arrangement for which has already been described.

Numerous and ©© from the varied lorikeet {Ptilosclera 
versicolor), blue-bellied lorikeet [Trichoglossus novae-hollandiae), and 
leatherhead {Philemon corniculatus), from Myall Lakes, New South 
Wales, April, 1912. Those found on the third host are obviously 
stragglers. 
In Text-figure 1 the heads of Menojion, Eomenojwn, and Heterodoxus 
are placed side by side for comparison. The ventral boimdary of the 
antennary fossa, which is really a ventral continuation of the temple, 
is indicated by a dotted fine. It will be seen that this fossa is most 
extensive in Heterodoxus, where it is floored by a plate with a ventral 
cleft corresponding to the dorsal cleft. In Eomenopon this ventral
