found abundantly on grass and on plants. S. strigicollis, Mots., is common 
on grape vines and where this plant is cultivated, is a serious pest. The 
late Mr. Jacoby wrote in the Fauna that this species could no longer 
be recognised, but he labelled a series of specimens from the Pusa col¬ 
lection with this name and omitted to record the localities in the 
volume. (It will probably be found to have a similar life-history to 
its ally the American grape vine rootworm, Fidia viticida, whose life- 
history has been described.) S. vittata is a larger form, found on Pan¬ 
chan juria (Vitis trifolia), which shams death extremely effectively and 
falls to the ground on its back, the brown lower surface and white 
patches making it very difficult to distinguish. 
Colasposoma is a large genus of moderate-sized metallic-coloured 
beetles, C. metallicus, Clk. and C. ornatum , Jac., being common in

the plains, Corynodes peregrinum , 
Fuesl., is a deep blue beetle, very 
abundant feeding on Ak and other 
wild plants and found throughout 
the plains, Nodostoma, Nodina , 
Heteraspis , Pseudocolaspis, Colaspis 
and Colaspoides , are the other com¬ 
mon genera. 
Pachnephorus bretinghami , Jac., and P. impressus, Ros., take the 
place in India that Myochrous takes in America, as being destructive 
to the young shoots of cane and cereals ; they are small dust-coloured 
beetles, with the appearance of weevils, found in numbers in the 
expanding leaves of the young cane shoots which they destroy ; hidden 
in the heart of the shoot, they are difficult to find and usually escape 
observation, the destruction of the young shoot being assigned to some 
other cause. 
Chrysomelince. —Though these beetles occur in all parts of India, 
very little appears to be known beyond the mere description of such 
species as have reached European collections and been described. Nor 
is there any complete list at present available and the recorded Indian 
species are buried in a voluminous and scattered literature. It is the 
least represented division with less than 70 recorded species. We are 
not aware of any species being of economic importance to agriculture
