PROCEEDINGS QF THE SECOND ENTOMOLOGICAL MEETING 275 
Borers are more important, as they do more damage, We know : 
Psiloptera fastuosa. 
Calosterna spinator. 
Stromatium barbatum. 
Psiloptera fastuosx [‘‘ South Indian Insects,” p. 297, fig. 140 | is 
common in babul plantations and perhaps bores in this tree, although it 
does not seem to have been actually noticed as doing so. Stebbing 
| Indian Forest Coleoptera, pp. 199-200, tab. 11] records the beetles of 
_ Ps. fastuosa as injuring the stem of babu’ trees at Buldana by peeling off 
the bark. 
Celosterna spinator |“ South Indian Insects,” p. 325, fig. 180] has 
been recorded as boring in babul but Stebbing | Indian . Forest Coleopt- 
era, pp. 358-362, tab. 25] records C. scabrator (under the name _ scabrata) 
and states that spinator is probably a variety of scabrator, which may be 
the case. The grubs bore in the stem and down into the roots and may 
do considerable damage. 
Stromatium barbatum |“ South Indian Insects,” pp. 321-322, fig. 175] 
has been recorded from Poona as found on babul, but I do not know 
whether it attacks living trees. : 
Of sucking insects on babu’ the most important is a Scale-sect, 
Anomalococcus indicus, which is abundant on babul at Coimbatore and 
sometimes occurs In such numbers as to cause the death of the trees 
attacked. It is attended by Camponotus compressus and one method of 
control is to ring the trees with a sticky mixture so as to keep these 
ants away. This Scale is parasitized by Hublemma scitula [“ South 
Indian Insects, ” p. 381, fig. 242 and p. 199, fig. 85] and by a small fly 
which is probably a species of Cryptochetum and I have actually seen — 
-the Camponotus standing over a Scale and warding off the attempted 
attack of one of these small parasitic flies. 
Oxyrhachis tarandus [‘ Indian Insect Life,” p. 731, tab. °78] is also 
common on babul and does some damage to young shoots by thrusting 
in its eggs and by the sucking of the bugs ; but how far it is an actual 
pest is doubtful. 
We will next take the various 
CRUCIFEROUS CROPS 
of which the first are the various species of 
Musrarps (Brassica juncea. 
,,  dichotoma. 
»»  canvpestris).
