Gahriua xaitthomelirnd polygoneiitic 



at "Washington. Read before the 

 Entomological Club of the American 

 Association for the Advancement of 

 Science, at Rochester, N. Y., August, 

 1892. 



Canadian Entomologist, v. xxiv, Xo. 10, 

 Kovember, 1892, pi). 282-286. 

 Show.s that while Oalcnica aanthouielcena, 

 according to I'rof. Johu 1!. Sinitli'n exi)eri- 

 nieiits, is siiiglebrooileil at New Brunswick, 

 N. J., it is normally doublebroodcd at Wash- 

 iugton, and by exception produces a third and 

 even a fourth generation there. Uiscutsses the 

 bearing of the.se facts in tlie light of climatic 

 iiifluince iu relatively short period.s. 



An additional note on the Bean 



AVeevil. 



Canadian Entoimdojist, v, xxiv. No. 11), 

 November, 1892, jip. 291-299. 

 In a note in tlie August, 1892, number of the 

 Canadian Entomologist the author stated that 

 the eggs of the Bean "Weevil "are preliminarily 

 laid upon the bean \>od iu the field, but chietiy 

 if not entirely upon those which are already 

 matured and ripening." The X""'^''^*^iit note 

 records the fact that tlie eggs hitherto taken 

 for those of the common Bean Weevil arc, with- 

 or,tmuc]idoubt,thoseof another Bruchus, eitlier 

 Erticl.vs qiiadiimaculatus or B. scutetlaris, and 

 that the eggs of the Bean AVeevil are thru.st 

 into an ai)erture made by the jaws of the par- 

 ent weevil along the ventral suture, or else laid 

 iu clusters on the inside of the pod wherever 

 this is sufficiently rijie to cause a partial open- 

 ing. 



Coleopterous lame with so-called 



dorsal prolegs. 



I'mc. Ent. Soc. Wash., n, No. 3, December, 

 1892, pp. ;il9-324, figs. 22-23. (Also sep- 

 arate.) 

 Shows that two kinds of larva; with .supjiosed 

 dorsal ]irolegs, referred to by Herbert Osborn 

 and others at the Indianapolis (1890) meeting 

 of the American Association for the Advance- 

 ment of Science, belong to Mordellistena, and to 

 some Cerambycid, and that tlio "prolegs" are 

 but abnormally developed tubercules to facili- 

 tate motion within the hollow stems. Cites 

 authorities and records the larva of Morddlis- 

 tenapustulata in dry stalks of Xanthiinn stnivia- 

 riiim ; of JT, unicolor in stems of Ambrosia artc- 

 misifulia ,- of J/, nvbila from stems of Triodia 

 cuproea ; full transformations of M. floridensis in 

 stems of TJniola paniculaia ; and of Oherea 

 tchaiimii in stems of Cottonwood. 



What the Department of Agriculture 



has done and can do for apiculture. 

 Proc. 23d Ann. Meeting of the Xorth Amer- 

 ican Bee-keepers' Association, December 

 27-29, 1892. 



RILEY, Chahle.s V. — continued. 



Kepriuted in the Canadian Bee Journal ■.ind 

 various other apicultnral journals. 



A r^'view of pa.st work iu apiculture, v.ith 

 recommendations for the future. The address 

 signalizes the fact that the first introduction 

 of Italian bees into the United States was due 

 to the Department of Agriculture, and toaches 

 upon the work of the apicultural .stations at 

 Aurora, 111., iu 1885, and at Michigan Agricul- 

 tural College in 1891, summarizing the results of 

 experiments ujwn foul brood, the relationof bees 

 to fruit, spraying with the arsenites as affect- 

 ing bees, selection in breeding, etc. Kecoiu- 

 mendations follow that the Department of 

 Agriculture secure theiutroduction and domes- 

 tication of desirable foreign races of bees, 

 experiment iu the crossing amd mingling of 

 races already introduced, in artificial fertiliza- 

 tion, the true causes of disease, etc. 



New species of Prodoxidae. 



Proc. Ent. Soc. Wash., n. No. 3, December, 

 1892, pp. 312-319, figs. 15-21. 

 Includes technical descriptions of the follow- 

 ing new species: Pronuba synthetica (larva, 

 chrysalis, and imago) ; Prodoxiis jiuloer^ilentus. 

 P.y-inrersus, P. reticulatus, P. coloradensis, and 

 1'. soididus.. 



On certain ]>eculiar structures of 



Lepidoptera. 



Proc, Ent. Soc. Wasli., 11, No. :!, iJecem- 

 bcr, 1892, pp. :i0.j-312, figs. i:i-l-t. (Also 

 si']parate.) 

 The paper describes some of the remarkable 

 striK'tures of the species of Pronuba and Pro- 

 (/o.r((,5iuiider the heads : ( 1 ) The radiate bodiesin 

 tin: receptacuhim seminis of Pronuba and Pro- 

 doxtis; (2) Pseudo-cenchri; (3) The tegulro and 

 I he i)atagia. The radiate bodies referred to, if 

 they occur at all in other insects, are never 

 found in anything like the remarkable develop- 

 ment iu which they exist in the species of the 

 family Prodoxidfe. Their function seems to be 

 to liberate the spermatozoa from the si)erniato- 

 phores. In conuection with two cenchri-like 

 spots on th;} luetathorax of Pronuba synthetica, 

 the author discusses the cenchri of Lepidoptera 

 and coiK'ludes that they are more likely organs 

 of sound than of any other sense. In discuss- 

 ing the tegubv and patagia it is shown that 

 nimh coufusidu on the part of authors in the 

 use of those terms has existed, and the original 

 definitions ot Westvvood and Kirby and Speuce 

 are held to be the proper guides.
