18 FIRST ANNUAL REPORT OF THE STATE ENTOMOLOGIST. 



of the two annual Reports of the U. S. Entomological Cominission; Re- 

 port 071 the Rocky Mountain Locust and other Insects in the Western 

 States and Territories; * Insects Injurious to Forest and Shade Trees ;\ 

 Half Hours with Insects ; and, Our Common Insects. Beyond the 

 above, Dr. Packard's writings in general entomology — anatomical, de- 

 scriptive, classificatory, and reports on special collections made in va- 

 rious portions of North America — have been very extensive and of a 

 high order. His Monograijh of the Geometrid Moths or PhalcBuidcB — 

 a beautiful volume of over six hundred quarto pages and an equal 

 number of illustrations, J has added largely to our knowledge of a 

 family possessing great economic importance; while \\\s Guide to the 

 Study of Insects has proved a rich boon to the American student, and 

 merits place in the hands of every one who desires a comprehensive 

 acquaintance with the insects of North America. 



Prof. J. H. CoirsTOCK's labors, as Entomologist to theU. S. Depart- 

 ment of Agriculture, have given results of much economic importance, 

 Avhich appear principally in the Departmental Eeport upon Cotton 

 Insects, 1879, and the Reports of the Entomologist for 1879 and 1880.§ 

 The main portion of the latter report is devoted to a very valuable paper 

 on the common and extremely injurious insects known as scale insects, 

 showing earnest study and extended investigation. An important ad- 

 dition to this report is a supplementary paper by Mr. L. 0. Howard, 

 of the Entomological Division of the Department of Agriculture, upon 

 the parasites of the Coccidce, in which many new species are described 

 and the benefit urged that may result from the transportation of the 

 more useful parasites from localities where they abound to those where 

 they may not have been introduced. 



The reports of Mr.TowNEND Glover, Entomologist of the Depart- 

 ment of Agriculture from the year 1863 to 1877, contain much mate- 

 rial of economic importance valuable for reference, but, from the 

 nature of his duties, not contributing to any great extent in original 

 investigation. In his Illustrations of Insects, consisting of 273 plates 

 drawn and engraved on steel by himself, and in the several volumes of 

 Manuscript Notes from my Journal, of Avhich small editions have been 

 lithographed for private distribution, he has displayed a zeal for the 

 promotion of science, not surpassed by any American Entomologist. 

 It is much to be regretted that the Illustrations in the Orders of Lep-
