unfavorable meteorological conditions was found to be a failure in 

 most cases. The author also notes as injurious a pyralid moth 

 (Loxostege frustalis), the peach maggot (Geratitis capitata), a serious 

 pest from a horticultural standpoint, attacking peaches, nectarines, 

 guavas, oranges, and loquats; and the red scale (Aspidiotus aurantii), 

 one of the worst foes of citrus growers, which was very injurious in 

 nearly all parts of the colony last year. The scale has no important 

 insect foes or enemies in the colony; the small ladybirds attacking it 

 have little effect and the imported species, with the exception of one 

 (Oreus australasice) have not survived. Fumigation has been success- 

 ful. The ptinid beetle (Sitodrepa panicea) was found attacking leather 

 and binding of documents in colouial archives. Phylloxera vastatrix 

 seems to be increasing, but .so far as known no leaf-infesting form 

 appears in that region. 



A useful American scale insert, L. 0. Howard (pp. 38-40). — It is noted 

 that there occurs in the southwestern part of the United States, on the 

 creosote bush, a light iusect (Cerococcus quercus) that seems important 

 on account of its commercial possibilities. Other species of the genus 

 found in North America noted are Tachardia mexieana, T. gemmifera, 

 T.pu8tuldta, T. fulgens, and T. cornuta. The commercial importance of 

 the Chinese and Japanese Erieerus pe-la and the Indian Ceroplastes 

 cerifcrus has already been established, and the species (G. foridensis) 

 occurring in the South in the gall berry deserves notice as does also 

 Gerococeus querent, which has been recorded as feeding on Quercus 

 oblongifolia, < L >. undulata, and Q. agrifolia. Eemarks are made on the 

 chemical character of the wax secreted by this insect. 



Insects of the year in Ohio, F. M. Webster ami G. W. Malty (pp. 40- 

 40). — Besides the periodical cicada (Cicada septendecim) and the chinch 

 bug (BU88U8 leucopterus), there are noted the San Jose scale (Aspidiotus 

 perniciosus), oyster-shell bark louse (Mytilaspis pomorum), Colorado 

 potato beetle (Doryphora 10-Uneata), asparagus beetle (Grioceris aspar- 

 agi), cankerworm (Anisopteryx vernata), bollworm (Heliothis armiger), 

 Braehyrhynehus granulatus, Coriseus ferns on Leptoterna dolobrata 

 tarnished plant bug (Lygus pratensis), bagworm ( Thridopteryx epliemerw- 

 f or mis) from which a tachiuid (Sturmia distineta) was bred; common 

 mealybug (Dactylopius adonidum), which was observed to be preyed 

 upon by the slug Li max eampestris ; Allorhina it it i da, usually not abun- 

 dant in Ohio, but reported as doing considerable injury in 1890 to 

 tomatoes in the southern part of the State, also as being very abundant 

 this year in the central part of the State; the tachinid (JBupkorocera 

 clarijH'nnis), which was reared from the larva of Ca'lodasys unicornis; 

 Gonotrachelus nenuphar, from which four samples of Sigalphus eurculi- 

 onis were reared; an unknown species of Tyroglyphus found affecting 

 walnuts and chestnuts; larvae of Papilio troilus, the time of the emer- 

 gence of the imago of which is noted; larvre of Onectra distineta, which 

 during the present year did considerable damage to young plums,
