Parandra brunnea Fab. This is one of the most omnivo 

 rous of longicorns. Living, as it evidently does, chiefly in 

 decomposing wood, it infests both deciduous and coniferous trees. 

 In my notes its occurrence is recorded under the bark of oak and 

 apple; in cherry wood {Prunus cerasus), just beneath the 

 tightly-clinging bark, and on willow (Salix alba), deeply buried 

 in the rotten wood. Mr. W. H. Ashmead has recently shown me 

 specimens taken under the bark of maple. I have also seen 

 specimens found under bark of elm and basswood, and Mr. M. 

 L. Linell informs me that he found it in abundance in the 

 hollow trunks of Ailanthus glandtdosus growing in the streets 

 of Brooklyn, N. Y. At Spring Lake Beach, L. I., it occurred 

 under bark of pitch pine {Pinus rigida). Dr. LeConte also 

 states that the species of this genus live under pine bark (Class. 

 Col. N. A., pt. II, p. 280). Others have recorded as food- 

 plants: beech (Horn), ash (Riley), and Tilia americana 

 (Townsend). At Washington, D. C., I have taken it at lights 

 during the second week of June. At Ithaca, N. Y., it appeared 

 in July. 



Callidium cereum Newm. was reared from the wood of 

 chestnut ( Castanea dentata) on two occasions : at Ithaca, N. Y. , 

 May 14, and at Clifton, N. J., May 30, occurring also in June. 



Elaphidion villosum Fab., under which name I include also 

 parallelum Newm., has most often been noticed as infesting 

 oak and hickory ; Haldeman has recorded chestnut and Abies ( ! ) ; 

 apple, plum, and grape have been added by Dr. Riley, and 

 peach and walnut by Professors Cook and Hopkins respectively. 

 To this I may add that I have reared the species from pruned 

 twigs of quince, locust, red-bud (Cercis canadensis), and from 

 trimmed ends of twigs of Osage orange {Madura aurantiaca). 

 In past years I have seen pear trees very extensively pruned by 

 this insect; also the climbing bitter-sweet ( Celastrus scandens) . 

 More recently I have ascertained that this or allied species attack 

 almost every woody plant that grows. In the vicinity of Wash 

 ington the genus Elaphidion is not so abundant as in most 

 northern localities that I have visited, but pruned twigs of various 

 trees and shrubs are of frequent occurrence, among which I have 

 noted spice-bush (Lindera benzoin), Sassafras officinale, 

 sumach {Rhus glabra and typhina). 



It has been noticed that this, as well as related species, does 

 not always prune the twig in which it lives, but I do not remem 

 ber to have seen mention of the fact that the insect sometimes 

 remains in the proximal end of the limb attached to the tree, 

 while the severed end is as often found empty, thus reversing the 

 usual order of affairs.
