Description. 
Beetle. Head not very large, rounded between the antenne, 
convex slightly in front, with short cheeks. Antenne do 
not reach to the middle of the elytra, are thin and filiform. 
Eyes large. | Prothorax ovate tapering towards the head. 
Elytra slightly convex, not meeting at posterior edges, thus 
leaving a portion of the abdomen exposed. Legs long and not 
very thick ; the femora slightly thickened and those of the hind 
legs reaching beyond the elytra. In the females the antenne 
are a little shorter and the femora of hind legs only reach to 
the elytra tips. See Pl. IV, fig. 2. 
Life History, ete. 
Little is known on the life history of this insect. The 
larva tunnels into the wood of the Oak (Quercus dilatata), and 
specimens of the mature beetle were discovered in the trees 
in August last and sent to me by the Ranger in charge of the 
Kilba Range, in the Bashahr State, Punjab. 
The insect is of interest, since it isclosely related to the © 
well-known coffee tree borer of South India, Xylotrechus 
guadripes, Chur. 
Observations are required as to how long the -larva of 
X. vicinus spends feeding in the tree, the length of time passed 
in the pupal stage, where the eggs are laid, etc.
