114 SPOLIA ZEYLANICA. 
The median lobes are situated in a cleft, narrow, tapering, 
strongly divergent, pointed, distinctly free at apex and serrated 
along the mesal margin and at the apex. 
The second lobes are duplex. The mesal half may be 
almost twice as broad as the lateral half, which may be well 
developed or minute (Z'urpinia) ; the mesal half may project 
caudally as far as the apex of the median lobes and may be 
slightly serrated on the lateral margin (Avocado Pear). Both 
halves are usually rounded at the apex. 
There are two short setz between the median lobes, a seta 
on the lateral side of the median lobes, a seta and a plate 
laterad of the median lobes. Thereafter in succession a 
prominent gland-pore, the second lobe with a seta on the base 
of its lateral half, a long plate broad at the base and abruptly 
narrowed thereafter, a prominent gland-pore, and three more 
gland-pores at intervals on the margin of the pygidium, the 
most anterior small, a seta being associated with the first of 
the three, and another lying near the third. No plates visible 
cephalad of the one laterad of the second lobes (Cupressus sp.). 
In an insect from J'urpinia sp. the setze between the median 
lobes project beyond the lobes. 
The number of gland pores on the pygidium is variable, 
though four appears to be the rule. In an insect from Avocado 
Pear only three could be made out on each side, one laterad 
of the median lobes, one laterad of the second lobes, and one 
slightly caudad of the level of the posterior end of the caudo- 
lateral group of circumgenital pores; and on one side the 
last-mentioned pore was either absent or so much reduced as 
_to be unrecognizable as such. 
In an insect from Walsura piscidia there was a plate cephalad 
of the third gland-pore and having a seta mesad of it. 
Circumgenital pores. Median in a distinct group : 8 (9 and 
5) (18 and 15), Walsura. Median group distinctly isolated : 
3 (12 and 11) (11 and 13) ; 2 of the 11 of the posterior group 
situated midway between the anterior and the posterior groups 
(T'urpinia). Median group of 8 in a double transverse row : 
Host ? 
Median and anterior-lateral groups practically in a con- 
tinuous arch, 5 (9 and 10) (13 and 13) ; 6(9 and 8) (12 and 12);
