398 SPH4ROTRYPES COIMBATORENSIS, n. sp. 

serious pest in the forest. It has evidently the power of swarm-- 
ing in considerable numbers and requires fresh bark in which 
to lay its eggs. At present it has only been-found in newly-- 
felled poles ; but it is more than probable that it would attack 
young growing saplings, especially sickly ones, were the former 
not available. Poles inspected, which had been attacked by the 
insect ard from which the beetles on maturing had left, were 
found to have their bast layer completely riddled by the pest,. 
whilst the bark externally showed, in addition to the entrance 
holes, numerous elliptical rings of exit holes placed close to one 
another, as shown in fig. 1c. An examination showed me that 
this insect appears tobe fairly free from parasites, as a close 
inspection failed to disclose avy larval remains in the larval 
galleries and pupating chambers. In the cases where larve have- 
been so attacked it is generally possible to find at Jeast the skin: 
of the head and perkaps a portion cf the thorax and abdomen: 
present inthe pupal chamber or larval gallery. Further, the 
holes in the elliptical ring on the bark usually corresponded in 
number with the larval galleries on the inner side of the bark. 
and in the sapwood. 
Further observations are required on this point. 
Previous to finding this insect the writer saw in the 
Coimbatore Forest Museum a portion of an Anogetssus post 
marked “attacked by insects.” The post showed a series of 
plans of the old egg and larval galleries evidently caused by 
a Scolytid insect. They resembie closely the ones described’ 
here, and the post had probably been attacked in the forest by 
this beetle. 
Protection and Remedies. 
Newly-cut poles shculd be at once remcved from the forest 
or barked. If neither is possible and a stream is close by they 
should be put into this for a couple of weeks. This will pro- 
bably be sufficient to render the bark distasteful to the insects.. 
in the case above described the trees had been cut for 
road-making purposes. Care should be taken to see that poles cut: 
in excess of the requirements are not left unbarked in the forest,. 
as was the case in this instance. The last part of April and first 
half of May, the last half of June and the first half of August are
