858 EXPERIMENT STATION RECORD. 



There is also noted a study of a new potato disease, due to the larvae 

 of a dipterous insect; and a new peach tree pest, the peach twig moth 

 (Anarsia lineatella). 



Annual report of the entomologist, A. ]). Hopkins ( West Virginia 

 Sta. B2)t. 1895, pp. 27-35). — During the year attention was given to an 

 insect affecting chestnut, oak, and pine bark, which in some instances 

 did considerable damage. Among the discoveries made daring the 

 year was an adult of the chestnut timber worm, which proved to be an 

 insect entirely different from what either Harris or Eiley had supposed. 

 Xyletinus peltatus was found doing damage to pine barn flooring, audit 

 was further noted as a dangerous enemy to seasoned wood of all kinds, 

 especially in outbuildings. Other insects noted are an enemy of the 

 poplar, a new apple tree pest, a new enemy of plum trees, which is 

 probably an imported European pest, the bag worm, clover leaf mite, 

 and an oyster shell bark louse. A new form of potato scab is also 

 noted. 



Notes on the insects of the year, F. L. Harvey (Maine Sta. Bpt. 

 1896, pp. 117-123; figs. 7). — The following insects are noted : Croton bug 

 (Pkyllodromia germaniea,), oyster shell bark louse (Mytilaspis pomorum), 

 which is abundant and increasing; hemispherical scale (Lecaniiim 

 liemispluvricum), elm tree bark louse (Lecaniiim (?), the fall canker- 

 worm (Anisopteryx pometaria), mourning cloak butterfly ( Vanessa anti- 

 opa), oak bark weevil (Magdalis olyra), steel bine flea beetle (Rait ica 

 ehalybea), buffalo tree hopper (Ceresa bubal us), which was this year 

 reported for the first time as doing damage to apple trees; yellow 

 necked apple tree caterpillar (Datana ministra), reported this year for 

 the first time as feeding on the foliage of apple trees; the currant span- 

 worm (I)iastietis ribearia), very abundant about Orono; gooseberry 

 fruit worm ( Dakruma con volutella), which is apparently on the increase; 

 lime tree winter moth (Ryberuia tularin), which is reported in injurious 

 numbers and seems to remain where the fall cankerworm is about to 

 disappear; the army worm (Leucania unipuncta), the ash gray pinion 

 (Lithophana antennnta), veiled a lappet moth ( Tolype velleda), which has 

 never been found before in Maine and was received from the western 

 part of the State, where it was mistaken for the gypsy moth; apple 

 tree tent caterpillar ( Glisiocampa americana), which is very abundant 

 in western and southern Maine ; currant fly ( Epochra canadensis), which 

 is not generally distributed, but badly infested some gardens in Orono; 

 apple maggot (Trypeta pomonella), which has nearly disappeared in sev- 

 eral localities; rat tail larva (Mollota), horn fly (Hcematobia serrata), 

 which seems to be on the decrease; buffalo beetle (An/h routs scroplm- 

 laria'), pigeon tremex (Tremex columba), and I'tinus fir, which was 

 reported as badly infesting a bag of timothy seed. The great number 

 of leaf-eating insects said to have been reported makes the season 

 somewhat remarkable. 



The army worm, B. H. Warren (Pennsylvania Sta. Bpt. 1896, pp. 

 161-220, pis. 16). — A description is given of the moth, its eggs and
