The larval galleries run irregularly through the heart-wood across and 
with the grain; they are fairly tightly packed with fibres and wood- 
dust; the diameter frequently reaches §". There are no visible galleries 
between the sapwood and the bark. 
The pupal chamber is an irregular excavation without definite shape, 
produced by a simple expansion of the larval gallery, which is padded 
with wood fibres to round off Irregularities. It lies a short distance 
below the outer surface of the wood. The exit holes are subrectangular 
with rounded corners.

DESCRIPTION OF THE STAGES. 
1. The Adult. 
General description. Closely resembling M. plagiata but 
differing slightly in the shape of the glossy patches on the thorax of the 
<$ and the relative length of the 3rd to 6th antennal joints. In the 6 
of this species the 3rd joint is equal in length to the 4th, 5th, and nearly 
half the 6th united. 
Length 37—52 mm. = 17-16—2^ inches. 
Technical description. See Lameere, 1903 and Gahan, 1906. 
2. The Larva. 
Technical description. The available material is a larval head 
capsule taken from a pupal chamber in Bombax malabaricum, Saharanpur,
