D. Hopkins, Ph. D., In Charge of Forest Insect Investigations. Bureau of Entomology. INTRODUCTION. The superfamily Scolytoidea is represented in North and South America, Europe, and Asia by some of the most destructive insect enemies of forest trees and their commercial products; also, by a very destructive enemy of clover, and by several species which injure or destroy fruit trees. This is the fourth contribution toward a monograph of the scoly- toid beetles. It was prepared for publication as Part IV of Techni- cal Series, No. 17, of the Bureau of Entomology, but owing to the discontinuance of that series m the new plan of departmental publi- cations, it has been placed in the series of Reports of the Office of the Secretary. Technical Series, No. 17, Parts I and II, of the Bureau of Entomology, comprise the first and third contributions; the first of these, Part I, is entitled ‘‘ The Genus Dendroctonus;”’ the third, Part II, is entitled ‘“‘ Preliminary Classification of the Su- perfamily Scolytoidea.”” The second contribution, entitled ‘ List of Generic Names and Their Type-Species in the Coleopterous Super- family Scolytoidea,’’ is published in the Proceedings of the United States National Museum, volume 48, No. 2066, pages 115-136. The subfamily Cryphaline of the family Ipide includes a group of ambrosia beetles, also known as pinhole borers and timber beetles, which are exceedingly detrimental to crude forest products, wine and beer casks, and other similar products; a species destructive to the tea plant in Ceylon, and many seed-infesting insects, especially those of the date palm. The fact that so many undescribed species and genera in the sub- family have been found in the course of the field and laboratory in- vestigations carried on by the writer during the past 20 years and the fact that many of them are of special economic importance make it necessary that they be named, described, and classified as a basis for a detailed study of their habits and seasonal histories and of the methods for combating them. 1 Contribution toward a monograph of the scolytoid beetles. Note.—This is a technical report of interest to entomologists generally. ie a eS > el Lea ee cl = OL eS eee 6 CLASSIFICATION OF THE SUBFAMILY CRYPHALINA, The classification of the subfamily Cryphaline, as here defined, is based almost entirely on a first-hand study of the material repre- | sented in the collections of the United States National Museum and | the Le Conte collection in the Museum of Comparative Zoology. The genera and species included in the classification which have | not been seen by the writer are indicated by angles (<) and are _ provisionally placed on evidence found in the descriptions. The names not in angles and not followed by reference to a page are of | described species represented in the collections. The names with | page references are new, except when followed by the author’s name. The collection also includes considerable new material from the in- | sect collection of the Biological Laboratory, Bureau of Sciences, | Manila, Philippine Islands, collected by Mr. J. L. Webb, under the | general instructions of the writer.1 | The descriptions of new genera are based on the type species and the descriptions of new species are based on individual types, but in | the case of a number of the genera many species, and in the case of | some species many hundreds of specimens, have been studied. | Revised descriptions of described genera are included in cases | where new species are added and, so far as possible, are based on the | type species as identified by the writer. If the type species is not available, its nearest ally is utilized. With this method of basing specific and generic diagnoses on an individual type, allowance must be made for a reasonable limit in the range of variation from the type, which should be brought out (as in Technical Series No. 17, Part I, of the Bureau of Entomology, U. S. Department of Agriculture) whenever a species or genus is discussed in a more comprehensive manner. The manuscript of this paper was completed and submitted for publication in January, 1913, and only includes references to species and genera described to January 1, 1913. 1¥For references to other collections. acknowledgments, explanation of abbreviations, etc., see preface and introduction to Parts I and II, Technical Series, No. 17, Bureau of Entomology, United States De- partment of Agriculture.

The male is slightly smaller than the female and its front is narrower. Notre.—The group of genera to which this genus belongs is charac- terized by the obscure to absent striz of the elytra and the presence of basal and lateral margins on the pronotum; the genera immedi- ately allied to it are characterized by the broad emarginate third joint of the anterior tarsus and by the emarginate eyes. Cryphalus, as here designated and restricted, stands out distinct from the other genere of the subfamily, and there seems to be no excuse whatever for including so many of the genera under this name, as has been done in Hagedorn’s Catalogue.

Morgantown, W. Va., in Hicoria sp., December 1, 1895; author, collector; Hopk. W. Va. No. 6907. Genus ANISANDRUS Ferrari. Antennal funicle 5-jointed, joint 5 much broader than 2; club oblong-oval, posterior half of anterior face cylindrical and chitinous, anterior half obliquely truncate, posterior face chitinous throughout, without sutures; pronotum broader than long, anterior margin broadly rounded and serrate; eyes oblong-elliptical, deeply emar- ginate. Note: This revised description is based on specimens of Xyleborus dispar Fab. from Europe, which is the type of the genus Anisondrus Ferr. The principal characters distinguishing this genus from Xyleborus, as represented by the type X. monographus, are the stout form of the body; pronotum broader than long, with the anterior margin serrate; the scape of the antenna long and slender as compared with that of Xyleborus, and the club longer than broad. In zimmermanni the scape of the antenna is short and the club moderately stout. In Xyleborus coronatus Eichh. the scape is also moderately short and the club differs especially in being subcompressed, with the anterior face oblique from near base and densely pubescent. I.

Norr.—This is closely allied to X. obesus variety minor Swain., as represented by specimens in the collection from Kennedy, W. Va., but the differences in size and other characters are sufficient to differentiate them specifically. It does not seem that X. minor Swain can be considered a variety of X. obesus Lec., but that it — should be considered a good species. id CLASSIFICATION OF THE SUBFAMILY CRYPHALINE. | 69 The name X.sayi is applied to the species because there is a specimen in the Harris collection, under his No. 1254, labeled ‘‘Scolytus pyri Peck (unique and det. by Say)’ and referred to in Harris’s MSS. notes as ‘‘Scolytus pyri Peck good, but not Scolytus, rather Bostrichus or ? true Tomicus—Worchester Dr. Funk.’’ There is also a specimen in the Harris collection of X. minor Swain., labeled ‘‘Scolytus pyri Peck.”’ Anisandrus obesus Leconte. This is undoubtedly a good species: There are large series of both sexes in the collection, which have been compared with the type in LeConte’s collection. LeConte’s failure to mention the teeth on the lateral margin of the declivity has pre- vented its recognition. X. serratus Swain. is evidently synonymous with X. obesus Lec. Anisandrus pyri Peck. After detailed study of a large series of specimens from North America and Europe it seems that we must consider pyri a good species. The females are scarcely to be distinguished by any constant character, but the males of pyri are at once distin-. guished, those of dispar being larger, the strie more deeply impressed, and the inter- spaces with more or less regular rows of small punctures. The epistoma of the female mounted in balsam shows striking differences—that of dispar being emarginate in the middle while that of pyri is sinuate. 4 - One ri. madeeetil. le one ‘ay | abt ecat sk ee See ee rises Me aoe tis 5 ome 5 a OPE e aay Wee, chee / SADR AEA. 2 908, te hres wat ett a S pales : +i tAL DS , : vein LOEGiOs eae ; ‘hiaapas . be Arora 7 - . e - te e i 6 aa gg : a ey TS 4 Ae dD SCOTT ers ‘ : i ; PERE Blag, tee RAS 4) eye, he, 4 : . bree, Orbe e E848, abe, biFs 28 2. haan Miers dee eee: phe tees treba a. ry * Witst Seleomcacibe.
