The work of a Decade upon Fossil Insects 1880-1889, by S. H. 

 Scudder [Annual address of the retiring president of the Cambridge En- 

 tomological Club Jan. 10, 1890. E.xcerpt from " Psyche," January, 1890.] 

 The author here gives a comprehensive and very readable account of the 

 work accomplished in this field in the decade just ended; a field in which, 

 as is well known, he has been the principal laborer. In speaking of the 

 relative abundance of fossil insects the author says: "During the past 

 summer, in explorations for the Geographical Survey, I found that the 

 strata of a considerable tract of country, certainly many, probably hun- 

 dreds of square miles in extent, lying in western Colorado and eastern 

 Utah, were packed with fossil insects as closely as at Florissant. There 

 can hardly be any doubt that we shall soon be able in our Western terri- 

 tories to rehabilitate successive faunas as successfully as has been done 

 with many of our vertebrate types, and as has not yet been done for in- 

 sects in any countrj- in the world. * * What we really need is a score 

 of trained workers to 'go in and possess the land.' No one would wel- 

 come them more heartily than one who is almost a solitary worker in the 

 American field." 



BiOLOGiA Centrali-Americana, Part LXXX of Zoology; November, 

 1889. — [Received January, 1890.] — Contains " Arachnida Araneidea," 

 by O. Pickard Cambridge, pp. 41-48, pi. iv, 83 figs., 18 colored; 11 new 

 species are described from the genera Epeira, Turckheimia and Carepalxis. 

 Coleoptera as follows : Vol. Ill, part I, pp. 145-168, plates vii and viii, 

 46 figs. 20 colored. This portion on the Buprestidce contains the descrip- 

 tions by C. O. Waterhouse, of many new species, usually illustrated in 

 colors. Vol. VI, part I, Supplement, pp. 153-168, plate xxxix, 34 figs. 25 

 colored. Many new species are here described by M. Jacoby, entirely 

 from Pachybrachys and Chlamys. " Lepidoptera Rhopalocera, Vol. II," 

 by F. D. Godman and O. Salvin; pp. 153-184, plates Ixiii and Ixiv, 55 figs, 

 all colored. This part contains the systematic consideration of the group 

 from Colias ccesonia to Enantia virgo. The pale Terias, allied to mexi- 

 cana in pattern, which was returned as from the Mt. Graham Range in 

 Arizona is here determined (with an excellent figure) as T. Boisduvaliana 

 Feld. ^= ingrata Feld. = gratiosa Reak. = mexicana Boisd. in "Sp. 

 Gen." The synonymy as worked out in this part is most instructive to 

 the student. " Lepidoptera Heterocera, Vol. I," by H. Druce, pp. 321- 

 336, contains the systematic treatment of this suborder from Dyops 

 ocellata to Arwniis agillacea. While reviewing this stupendous work it 

 may interest our readers to know that the following entomological volumes 

 have been completed : Coleoptera, \'ol. I, part i [Adephaga), by H. W. 

 Bates; Vol. I, part 2 {Adephaga, etc.), by D. Sharp; Vol. Ill, part 2 {Mala-
