Oriental Scolytide of economic importance. 425 
(3) Xyleborus fornicatus, Kichh., recorded by me (loc. cit., 
p. 214) as injurious to the tea-plant in Ceylon, and again 
referred to below; (4) Eecoptopterus sex-spinosus, Motsch., 
previously recorded as injurious to the rice-plant in 
Burma. 
I imagine that XY. fornicatus is the “smallest species, 
with smooth elytra.” 
(c). Further examples from Cocoa-trees. Mr. Green 
writes : “I was of opinion that the beetles [consignment )] 
were not primarily responsible for the injury, and this 
opinion has been corroborated by the discovery of a fungus 
in all the diseased specimens of bark submitted to Kew. 
“JT am now forwarding two more species of Scolytid 
beetles that are found in the younger branches of the 
Cocoa-tree, which really are injurious to the plant. They 
form their tunnels in what appears to be healthy wood 
and rapidly cause the death of the parts attacked. A 
dark chocolate or purplish stain spreads through the 
tissues of the wood surrounding the galleries of the 
insect.” 
The two species are both new, and are described under 
the names of Yyleborus mancus and X. discolor. 
PENANG. ‘Species injurious to Nutmeg-trees.” 
Mr. C. O. Waterhouse has received and has com- 
municated to me examples of three species. The majority 
belong to Phlwosinus ecribratus, Blandf. (Trans. Ent. Soc. 
Lond., 1896, p. 198), first described from the refuse of 
Sumatra tobacco ; they vary considerably in length (2-3:4 
millim.), but not otherwise except that in some, presum- 
ably males, the apices of the 1st and 3rd elytral interstices 
are not tuberculate. 
Besides these, there is an individual which appears to 
belong to a distinct species of Phlwosinus, and is left 
undetermined; there are also examples of Xyleborus 
Sornicatus. 
Descriptions follow of the species, five in number, sent 
in these various consignments, which appear to be new 
and recognisable.

Q. S. mikado 9, Blandf., forma adeo similis, elytris tamen
