In the type specimen tlie second recurrent nervure is 
received only just beyond the middle of the second cubital 
cell, and the carina at the base of the first dorsal abdo¬ 
minal segment is very indistinct. There is a specimen 
from Cape Colony in the Berlin Museum which I refer 
with doubt to this species in which the second recurrent 
nervure is received much nearer to the apex of the cell, 
the carina of the first segment is more distinct, and the 
punctures are rather coarser, the insect is also much 
larger. But it is not advisable to found a new species 
in this diflficult genus on a single specimen in which the 
differences are so slight, especially as a specimen in 
the British Museum from Howick, Natal, is somewhat 
intermediate. 
Large collections of the species of Tiphia with full data 
are much needed. My impression, derived from a season’s 
collecting in Assam, is that seasonal forms may occur as 
in Lepidoptera. 
Tiphia siinlaensis, Cam., was plentiful in April and May, 
but none were taken later, whereas Tiphia himalayensis, 
Cam., was taken in August and September, but not in the 
spring months. T. himalayensis is twice as large as sim- 
laensis, the median segment is a little longer, the carina on
