overlooked up to the present), one is the seventeen-year cicada (com- 

 monly, but improperly, called locust), Cicada septendecim. Its injuries 

 are inflicted by the female boring into the twigs for the deposit of its 

 eggs. It has not been observed to oviposit in pines {1st Rept. Ins. 

 Mo., p. 24). The other, Lioderma ligata, or the bound tree-bug, so 

 named from the red band surrounding its margin, is 

 represented by Dr. Pitch, as *' sometimes clinging on 

 this tree, and probably sucking the juices of the leaves." 

 It may not, however, be accepted as an injurious species 

 Avithout further observation of its habits, as several of 

 its near relatives are known to subsist upon the juices 

 of other insects which infest our trees. Dr. Fitch, in Fig. s-The bound 

 his 3d Report, page 71, No. 100, includes this insect, Jeema^^'ligata 

 under the name of Fentatoma ligata, among those which (After Glover), 

 affect the leaves of grapes by puncturing them and sucking their 

 juices, it is shown in Figure 8. 



Of the Orthoptera, the Rocky Mountain loctist, Galoptenus spretus 

 (Figure 9), according to Prof. Rilej^, in 

 periods of its abundance, often strips 

 the leaves of the hemlock, arbor-vitse, 2 

 the pines, and the Norway spruce. The 

 injury to these evergreens is serious. Fig. 9.— The Eooky Mountain Locust- 

 as they are much more sensitive to Galoptenus speetus — Female. 

 defoliation than deciduous trees. {First Report U. 8. Entomological 

 Commission, p. 253.) 



Several of the insects noticed above are believed either to attack 

 only sickly or diseased trees, or those already dead, yet their opera- 

 tions and their history may be quite as important and as deserving of 

 observation and study as those which confine their attacks to living 

 and healthy vegetation. This view of the comparative importance of 

 the two classes has been so ably presented by Dr. Asa Fitch, that we 

 quote from his Fourth Report on the Insects of New York (1859, pp. 2, 3), 

 a portion of his remarks prefatory to his consideration of the Insects 

 Infesting Evergreen Forest Trees : 



" The evergreens are so highly esteemed for ornamental j)ury)oses, 

 and some of them, particularly the pines, are so valuable on account 

 of the timber that they yield ixs, that we are much interested in 

 knowing the insects which we have in this country, which infest these 

 trees to their injury, either by stunting their growth, marring and 

 deforming them, or causing their premature decay and death. Fori 

 tunately for us, it is upon trees that are sickly and decaying, or upon 

 their dead trunks and timber, that most of these insects make their
