49.4. Mr. W. F. H. Blandford on some 
E. Himatayas. “Taken from stem of a young 
India-rubber twig, Ficus elastica—Tieta Valley, 1,100 ft., 
30th July, 1897” (£. P. Stebbing). 
One new species, described under the name Diamerus fict. 
CuitTacone. “Destructive to Mahogany-trees in the 
Chittagong Hill Tracts” nd. Mus.). 
Monsieur P. Lesne, of the Paris Museum, has forwarded 
me examples of two species received by him among 
Bostrychide from the Indian Museum, Calcutta, with the 
above description of their habits. They belong to two 
very interesting new forms, described under the names of 
Scolytoplatypus brahma and Xyleborus gravidus. 
CryLon. The following specimens have been forwarded 
to me by Mr. E. Ernest Green :-— 
(a). “Species injurious to ebony seed.” 
Numerous examples, which I am inclined to refer to 
Coccotrypes integer, Eichh., originally described from 
Siam. I have not seen the type, but have made a 
comparison of the specimens with a typical example of 
C. pygmexus, Eichh., which Eichhoff very carefully 
differentiates from C. integer. The habit of seed-boring is 
common to the genus, and C. dactyliperda constantly 
attracts notice in the East as a date-borer. 
(b). Species supposed to cause disease to Cocoa-trees 
(Theobroma cacao). Mr. Green writes of these :—“ Stems 
of the diseased trees were submitted to me, and I found 
the enclosed specimens either in the rotting bark or in 
the wood itself. It was the smallest species, with smooth 
elytra, that seemed to tunnel deepest. But I gave it as 
my opinion that the beetles were not the cause of the 
disease, but were attracted by the altered sap and dying 
wood. I thought the real cause was either some fungoid 
disease or unsuitable soil. The whole sap of the tree was 
altered and turned sour, whereas the tunnels of the 
beetles were very small and widely separated.” 
Examples of four species were received: (1) a Crosso- 
tarsus, which I take to be C. sawndersi, Chap., although it 
differs slightly from the type in the direction of C. fair- 
mairet, Chap.—probably both forms are races of one and 
the same species; (2) Xyleborus semigranosus, Blandf., 
previously described by me (Trans. Ent. Soc. Lond., 1896, 
p. 211) from the refuse of imported Sumatra tobacco ;
