 tiou of iusecticides -with fungicides; the gas 

 treatment; the resin washes; the fluted scale,

Partly reprinted in Insect Life, v, Xo. 1, pp. 

 16-19. 



The tirst larval or post-embryonic 



stage of the Pea and Bean weevils. 

 Canadian Entomologist, v, xxiv, Ko. 7. 

 August, 1892, pp. 185-18G. (Also separate.) 



A short note iipon the curious temporary 

 thoracic legs in Bnichus fabte. (obteetiis) and 

 B. irisi, which serve them in entering the bean 

 or pea and are then lost with the tirst molt. 

 The classiticatory significance of the.se heredi- 

 tary post-embryonic structures is discussed. 



Some notes on the Margined Soldier- 

 beetle {ChauVtognathus margiiiaiua). 



Canadian Entomologist, v, xxiv. No. 7, 



August, 1892, pp. 186-187. (Also separate.) 



Records and describes the eggs of this species 



hitherto unknown. As many as 300 are laid in 



a single mass. The first larva stage is also 



compared with the final stage. 



Some interrelations of plants and 



insects.

Also as a separate. 

 Discusses the pollination of Yucca filamen- 

 tosa by Pronuba yuccaiella; the structural char- 

 acteristics of I'roiuiba ; the acts of pollination 

 and oviposition , the develoj>ment and trans- 

 foruiatiiins of Pronuba ; the bogus Yucca moth ; 

 other species of Prodoa-w«; caprification of the 

 figure. In generalizing from the facts, the 

 author indicates three principal lines along 

 which variation has proceeded ; shows how 

 these Prodoxids exemplify what he originally 

 called "fortuitous variation:'' and discusses 

 the transmission of acquired characters through 

 heredity. 



Rose Saw-flies in the United States.

 Observations upon the Bristly Rose-worm, 

 Cladius pcctinicornis, Fourcr. ; the Banded 

 Emphytus, or Curled Rose-worm, Emphiftiis 

 cinctus, L.; and the American Rose-slug, 2lon- 

 ostegia rosoe, Harris. Life history of the three 

 species compared and original observations 

 given. All are amenable to treatment with 

 hellebore. 



New injnrious insects of a year. 



Extracted from a paper entitled 



RILEY, CiiAKLE.s V. — <'()Utiiiued. 



" Recent Advances iu Dealing with 

 Insects Affecting Fruits," read before 

 the American Pomological Society^ 

 September, 1891. 



Insect Life,\, No. 1, September. 1892, pp. 16-19. 

 Forty-five hitherto unrecorded species, re- 

 port e<l to the Department of Agriculture duiing 

 one year as injuring various crops, are enumer 

 ated. 



Further notes on the new Herljariuni 



Pest. 



Insect Life, v, No. 1, September, 1832 pp. 

 40-41. 

 Tlie new herbarium pest, Carphuxera pte- 

 learia. described in Insect Life, IV, pp. 108-113, 

 was thought by Mr. R. McLachlan to be very 

 like Acidalia herbaria fa. Fab., long known to 

 injure herbarium specimens iu Europe. By 

 comparison of the imagin of the two species, 

 however, the author finds that the European 

 motli is twice as large as the American 

 species, more glossy, and differently marked 

 in detail. In structural characters Carphoxera 

 ptelearia is easily distinguished from Acidalia 

 hcrbariata by the spatulate tubercles of the 

 larviie, by the lateral projection on the fifth 

 abdominal joint of the pupa, and by its much 

 smaller size, more pulverulent, less glossy 

 scaling, and difl'erent markings in the imago. 



Preservation of hard-wood handles. 



Scientific American, lxvii, No. 14, October 1, 

 1892, p. 216. 

 Report ujjon an insect damaging hard-wood 

 handles ; probably one of the powder-post bee- 

 tles of the genus Li/cttis, species undetermined. 

 Soaking the infested handles in kerosene is 

 recommended as a remedy. 



California Beer Seed. 



Scientific American, L.wil, No. 14, October 1, 

 1892, p. 217. 

 Report upon a specimen of a fermenting 

 principle, the action of which is due to a bacte- 

 rium and a fungu.s, the species of which iiave 

 not been definitely settled, though the former 

 is probably IHspora caucasica anil the latter 

 Saecharomycer, kefi/r. 



An Australian iScymnus established 



and described iu California. Paper 

 read before the Rochester meeting of 

 the Association of Economic Entomol- 

 ogists, August, 1892. 



Scientific American, Lxvn, No. 18, October 



29, 1892, p, 275; Insect Life, v. No. 2, 



November, 1892, pp. 127-128. 



An Australian Coccid-feeding Coccinellid 



brought over by Mr. Albert Koebele inl888-'89, 



and subsequently lost sight of, has turned up 



in southern California and been described by 



Dr. F. E. Blaisdell under the name Scymnut 



lophanthce. as an American species.
