LAMIA (2) sp. 
Reference :—Provisionally determined as Lamia (?) sp. 
Classification:—Order, COLEOPTERA. Family, Cerambycide. 
This is the beetle whose thick white grubs have been reported 
as boring into the wood of the roots of Casuarina trees at 
Cuddalore. 
Larva.—A thick whitish-yellow grub with blackish brown 
head and black mouth parts /(mandibles) followed by a largely 
developed segment which ts slightly darker yellow than the 
following ones. These latter taper slightly to the tenth which 
is half the size of the prothoracic segment. Last two seg- 
ments smaller ending in a blunt point. Length 134th inch. 
Breadth across the big segment behind the head (prothoracic 
segment) #,th inch. 
Beetle. — 2. Black, moderately shining. Abdomen very 
dark red beneath. A short thick beetle with a vertical head. 
Prothorax sculptured and spined above and at sides, widest in 
middle. Joined on to the elytra (wing covers) by a short neck. 
Elytra wider than hind portion of prothorax, parallel to near 
apex where the outer edges turn inwards, the elytra thus termi- 
nating ina blunt point. Elytra entirely cover the base of body. 
They are corrugated and spined at their basal portions and pitted 
strongly for the rest of their length. First joint of antenna is 
swollen and well marked. Length thirteen-sixteenths inch. 
Life-History. 
We know little at present about the life-history of this 
insect. The grubs attack and live in the cambium layer and 
sapwood of the roots of the tree and are said never to be found 
in the stem. Grubs were found in this position on the 1st June, 
and one mature beetle was obtained from the Talaukoda 
Plantations near Cuddalore. There are no records as to the 
amount of damage this beetle commits. Since it lives in the 
cambium layer of the roots it is likely to prove a very serious 
pest when present in any numbers in a plantation.
