162 HETEROCEROUS LARVZ IN ACORNS OF Q, SEMICARPiFOLIZ. 

Owing to constant shifting of camp I failed to breed out 
any of the moths from these caterpillars, It is not improbable 
thatthe larve pupate in the soil after the acorn has dropped 
to the ground, 
We have still to observe, with reference to these insects, 
where the eggs are laid, how long the larve spend in the 
larval stage, where they pupate, and when the moths appear. 
Until the latter are found the insects cannot of course be 
named. 
OTHER HETEROCEROUS LARVA ATTACKING THE ACORNS OF 
QUERCUS SEMICARPIFOLIA. 
Description of larve. 
Three different kinds of caterpillars appeared to be present, 
all differing in appearance, two markedly so, from those already 
described as accompanying Cadlirhytis semicarptifolig: 
No. 1. Whitish-translucent with markings similar to the 
one already described ( (1) above) but the grub 
was much larger, being 3 inch in length, This 
may prove to be the same as one of the two 
found with C. semicarpifoliz. 
No. 2. This differed totally in appearance. Yellowish- 
red in colour, with a black head and a row 
of blackish tubercles down each side situated 
above the median plane. Length $ inch, 
No. 3. A larger caterpillar, ? inch in length, differed in 
appearance from the above both in size and 
colouration, etc., though I considered it might be 
only in a more developed stage. It was dark 
brown and hairy on its dorsal surface, yellow 
on its ventral one, with a yellow head and 
thoracic segments. Dorsally it was covered 
with numerous tubercles bearing tufts of brown 
hair; running down each side, were a row 
of orange-coloured tubercles bearing shortish 
tufts of hairs of the same colour together with 
pencils Of long, fine, yellow hair.
