have been received yet, but renewed examination of the larva . 
seems to confirm our opinion previously expressed (I. c. p. 253), 
viz: that it is a Cerambycid allied to Oberea. If so, the species 
in question is possibly Spadlacopsis suffusa Newm., which is by far 
less rare in the Southeast than is generally supposed. The per- 
fect insect occurs in large numbers, in June and July, in very wet 
grassy places, its larva doubtless boring in the stems or roots of 
grasses which are more or less covered with water. The beetle, 
owever, is very liable to be overlooked even by an experienced 
collector, as when approached it “ plays possum” and is then 
almost undistinguishable from a piece of dry grass. 
The “ water weevil”? mentioned by Mr. Screven as injurious 
to rice we conjecture to be a species of Centrinus (perhaps C. 
concinnus Lec.?) or of an allied genus of the Barini group, as 
several species thereof occur in great numbers in wet, grassy 
places in the South, and as the larve of this group are known to 
live in the roots or stems of plants. 
In this connection we would finally call attention to the re- 
ported recent appearance of a formidable insect enemy to the rice 
plant in the East Indies. Mr. Wood Mason, deputy superintend- 
ent of the India Museum has identified it as belonging to the 
genus Cecidomyia, which genus “has never before been found in 
India,” and proposes the name of C. oryzae, for the species, which 
threatens to become very destructive to the rice crop.
