 Entom., Concord, N.H., ix, no, 6, December 191G, pp. 551-556. 



Diabrotica duodecimpunctata, 01., is increasing in Texas and from 

 April to June is found on many fruits, vegetables, garden and \yild 

 flowers. Experiments sliow that these beetles are capable of adap- 

 tation to change of diet. Hibernation experiments were inconclusive ; 

 the adult can be found throughout the winter on the coSee bean 

 {Daubentonia longifoJia) in sheltered spots in woods and, when kept 

 imder artificial conditions, was not observed to hibernate. Dr. Huxley 

 has suggested that material may be stored up in the bodies of the 

 insects, thus obviating the necessity for hibernation under certain 

 conditions. Flight experiments seem to show that there is a decided 

 gain in endurance on the wing corresponding to the length of a period 

 of fasting, and it seems possible that the insect prepares for winter by 

 storing tissue that is available for migration in localities where hiber- 

 nation is not necessary. Fasting can be endured much longer if the 

 insects are kept violently exercised, and beetles exercised until fatigued 

 almost every day without food, were much more lively than those kept 

 in cages 'W'ith abundance of food. An attempt was made to study the 

 field-habits in July, but marked beetles disappeared rapidly and very 

 few were seen again.

 Concord, N.H., ix, no. 6, December 1916, pp. 556-561. 



TeninjKiIjms biocidafus, McG. [see this Revieiv, Ser. A, iii, p. 306] has 

 been found abundantly in the south-eastern States, and is not by any 

 means confined to privet {Ligustrum spp.), although it shows a decided 

 preference for this plant, which often succumbs to its attacks. A full 

 description of the various stages and life-history of this mite are given. 

 As in previous experiments, lime-sulphur was found to be the best 

 insecticide against it.

Jl. Econ. Entom., Concord, N.H., ix, no. 6, December 1916, 

 pp. 561-566, 2 plates. 



In the course of some preliminary experiments the settling properties 

 of some commercial samples of lead arsenate paste were found to be 

 affected by freezing, while others were not. The microscopic appear- 

 ance of all the pastes examined was altered and their adhesive pro- 

 perties may be aft'ected, but what influence this would have on their 

 use in sprays is unknown. Further experiments in this connection 

 are to be made. 



Wheeler (W. M.). An Indian Ant introduced into the United States.^ 

 Jl. Econ. Entom., Concord, N.H., ix, no, 6. December I9I65 

 pp. 566-569, 1 pi., 1 fig. 



The common Indian ant, Triglyphothrix striatidens, Emery, has 

 recently spread into the United States. This ant, of which a descrip- 

 tion is given, is very liable to be imported with tropical plants. A 

 bibliography of 15 Vv'orks is appended.
