216 FAMILY BUPRESTIDAE 



the larval gallery is filled ; the diameter of the tunnel is a quarter of 

 an inch. The beetle, on maturing, crawls up out of the pupal chamber 

 (the larva turning round in the pupal chamber so as to face upwards, as is 

 usually the case with these wood-pupating grubs), bores its way out through 

 the bark above, and escapes from the tree. 



In the sapwood of a large Tcrminalia tree which had been felled 

 some time in September or October the preceding year I took a number of 

 dead beetles in situ in their pupal chambers ; also a few fully-grown larvae. 

 An examination of. the tree showed that the main bole had been attacked 

 from top to bottom by this insect, the major part of the bast having been 

 removed by the grubs. Most of them had matured and left the tree either 

 in December or January, the beetles found in the first week in March being 

 quite fresh, and, though dead, not yet dried and desiccated. The larvae 

 found were taken on 9 March, and were either very belated ones, or had 

 resulted from fresh eggs laid in the tree near the base of the butt (where the 

 sapwood was still moist) by the December or January generation of beetles 

 which had matured in the tree. The fact that a generation of the beetles 

 issues in the cold weather appears to render it certain that the insect passes 

 through at least two life-cycles in the year, and there may be more than two. 



From the data on its life history already known this small buprestid 



must be looked upon as one of the dangerous forest

in the For t pests. We do not yet know what trees, other than 



the Terminalia, it infests, but it will probably be found 



to have several hosts. It is a hardy insect, and capable of increasing 

 rapidly in considerable numbers when circumstances are favourable to it. 

 Its life history consequently requires to be understood.
