them a new enemy no less dangerous ; this was a beetle belonging to the 
genus Apotomorrhinus, of which there were only four species known at 
* this time, two inhabiting Ceylon, one Pondicherry, in India, and one 
Manila. It was shown to me for the first time by M. Couston, a nursery- 
man, of Marseilles, who had bought the greater part of M. Lunglassé’s 
importation. I succeeded in capturing two of these insects at his place in 
April, 1898. In September of the same year I found one in my glasshouse 
on a Phalenopsis amabilis from the same source. It is probably a new 
species. The insect can easily be recognised by its proboscis. It is from 
three to four millimetres in length, of a blackish-brown colour, and its 
habits are nocturnal. Its grubs live in the collar of the Phalenopsis, while 
the adult gnaws the leaves and the flower spike. Since it multiplies very 
rapidly, it can do much damage. At M. Couston’s place I have verified 
that it also attacks Selenipediums, for S. X Sedeni and S. x grande had 
their leaves eaten by the Apotomorrhinus. 
Shortly after this time I received direct from a grower in Singapore 
some Phalenopsis Aphrodite and Schilleriana. On examining them, I 
found in the centre of a P. Aphrodite another Apotomorrhinus, but of a 
different species. It was smaller in size, and its wing-cases had spots of a 
yellowish-white. Its habits are probably the same as those of the preceding 
species. 
Lastly, in February of this year, I received from my friend, M. Maron, 
the well-known nurseryman, an example of another Apotomorrhinus, 
which had been sent to Marienfelde by M. René Gaveau, who gave the 
following information concerning it :—‘‘ This insect was introduced with 
some Phalzenopsis amabilis var. Rimestdiana, and we have killed hundreds of 
them. It generally gets into the sphagnum between the roots of the plant ; it 
comes out at night, and attacks, for preference, the young leaves and the 
flower spikes. When a young leaf is attacked, in contact with moisture it 
rapidly decays. If it isa flower spike which is attacked, the buds quickly 
turn yellow and drop off. The grub attacks only the collar of the plant, 
which it sometimes manages to ee cut = ” This insect has been 
described under the name Ap While bli 
very much that found in M. Langlesse’s se it differs from it in 
the spotting of the wing-cases. 
To be free from this insect, in the first place, never introduce a 
Phalznopsis into your house before carefully examining the leaves and the 
collar of the plant. Then, ifan established Phalenopsis is noticed with its 
leaves eaten, the sphagnum should be searched for the insects. It should 
be remembered that in default of Phalznopsis the insect can live on 
Selenipediums and probably other tender-leaved Orchids. 
At present the only Orchids known to introduce these Orchid beetles
