and stout. Abdomen large, the broadest part of body broadly 
rounded caudad. 
Four adult specimens and three nymphs of this large and 
striking psyllid are before me, collected in Pollibetta, Coorg, 
India, on May 27, 1914, from galls on leaves of an unidentified 
tree.

This subfamily has ‘much larger representation in tropical 
countries, only a few species being found as far north as the 
southern United States. Previous to 1911 so few representa- 
tives of this subfamily had been discovered and examined that 
those few were assigned positions in genera variously related 
to the other Psyllidse ; but when an increasingly large number of 
forms from many tropical localities began to come to hand, it 
became apparent that a comparatively large tropical fauna of 
this type existed. 
As our knowledge of this group advances we shall no doubt 
have to recast our taxonomic conceptions. One of the most 
striking peculiarities of the representatives first examined was 
the deeply cleft head, with the thickened antennae enhancing 
the cleft appearance, and the absence of genal cones. Exam- 
ination of more species of this subfamily, however, has shown 
that these characteristics are not to be found throughout the 
subfamily, though the genal cones usually are absent. The body 
always has a characteristic elongate form, and the wings have 
a peculiar venation; though this latter peculiarity is one not 
easily explained nor easily appreciated by one unfamiliar with 
the group. 
As the tropical countries of the world are more carefully 
explored for their insect life, it is probable that many new and 
perhaps quite different types of this subfamily will be brought 
to light, necessitating changes in our taxonomic disposition of 
these very interesting little creatures. 
The following subfamily description is intended to supersede 
the previous definitions of this group: 
Body typically elongate, often slender. Head usually cleft in 
front, vertex more or less concave on front margin and genae 
swollen out forward beyond vertex at each antennal base, and 
the latter often swollen and increasing the birostrate appearance 
of the head, but in at least two genera, Nesiope and Tenapha- 
lara, head not birostrate. Genal cones usually wanting or very 
small and inconspicuous. Beak very long. Eyes hemispherical, 
usually not at all recessive. Antennae usually long, often thick-
