118 Arthur M. Lea : 



against their will, and on the nest being disturbed by the cover- 

 ing stone being removed, such victims temporarily regained 

 their liberty. 



In addition to the species now recorded a very small flavous 

 beetle was seen in fair numbers in a nest of white ants on the 

 Richmond River, but all were extremely active, and managed to 

 escape with one exception, which was rather badly crushed. Its 

 antennae are clavate, and it has a conspicuous curved stria on 

 each side of the prothorax. It is in anything but good condi- 

 tion for examination, but such as it is Mr. Blackburn suggests 

 the possibility of its belonging to the Erotyllidae. Mr. Elgner 

 also sent some large larvae as from white ants' nests. One is 

 almost three inches in length, and evidently belongs to the 

 Carahidae (probably Feronides). A second species (two of it 

 sent) is about an inch and a-half in length, with a very large 

 body and minute head : it is evidently Coleopterous, but I have 

 no idea as to its family. A third larva evidently belongs to 

 the Eroti/llidae, but is too large to belong to the species here 

 described as E pisca pliula termitophila. 



As some of the species are very singular I was unable to 

 place them in their families or genera at sight, and being 

 usually represented by single specimens, that it was inadvisable 

 to destroy in examining their mouth parts, I sent some to the 

 Rev. T. Blackburn for his opinion, and one to Mr. George 

 Lewis, and under such species their opinions are herein given. 



This paper is purely systematic ; as although the relations 

 existing between the ants and their guests, often very unwel- 

 come ones, are very interesting ; it was not now considered 

 advisable to deal with such relations, as they would have unduly 

 lengthened an already long paper, and are l^est considered 

 separately. 



• For most of the names of the ants, bees and termites I have 

 to thank Mr. W. W. Froggatt. Many of the beetles, however, 

 were unfortunately simply noted as being from nests, without 

 specimens of the ants, etc., being saved for reference. Tlie 

 known hosts are as follows: —
