found on a nutmeg tree in Malacca, and made some remarks 
on Formica smaragdina, which makes its nest on the trees, 
joining the leaves together by a thin thread of silk at the ends. 
He stated that the first step in making the nest is for several 
ants to bend the leaves together and hold on with their hind 
legs, and one of their number after some time runs up with a 
larva and irritating it with its antenne makes it produce a 
thread with which the leaves are joined; when one larva is 
exhausted a second is fetched, and the process is repeated. 
Paper read. 
Mr. Waterhouse read the following paper entitled, ‘‘ Some 
‘‘remarks on the Antenne of Insects.” 
““T have lately been preparing a series of antenne for 
‘‘exhibition in our Museum. There were one or two points 
‘upon which I wanted information, but which I failed to 
‘‘ find recorded in a satisfactory manner; and there are one 
‘‘or two points, which, although touched upon by Herr 
‘‘ Kolbe in his excellent work, ‘ Kinfiihrung in die Kenntnis 
‘“« «der Insekten,’ have not had sufficient prominence given to 
‘‘them. I venture to call attention to these this evening. 
‘Tn the first place, | wanted to know the extreme limits in 
‘the number of joints in the antenne. I found these varied 
“from two in Platyrrhopalus and some other species of 
‘** Coleoptera, to 480 in Meroncidius, one of the long-horned 
‘‘ Locusts. Articerus, one of the Pselaphide, is said to have 
‘an antenna consisting of a single joint, but my examination 
‘‘did not satisfy me that this was really the case. Possibly 
‘“some Locusts may have even a greater number than the 
‘species I counted. In the Lepidoptera I found the number 
‘‘ of joints varied from 17 in Oncopera, one of the Hepialide, 
‘to 120 in Thysania, a large Mexican Noctuid. 
‘“‘The next point I would call attention to is the club of 
“the antenna. In certain groups the antenne always 
‘terminate in a club; but it is curious to note certain 
‘species appearing with a clubbed antenna, when all their 
‘allies have simple antenne. In the Longicorn Coleoptera, 
‘‘for example, there are some 10,000 species, all with more 
‘or less linear or acuminate antenne, but Telocera, an
