juid I.socmtm oulgark. The only roniodios thus far sugt^ested against 

 this insect are the use of kerosene emulsion and tii(> rotation of crops. 



A note on the Mexican hean %meml{Spermop]M(j ax pectoraliH) (pp. 37, 

 38). — The species is known to inhabit Nicaragua, Guatemala, Panama, 

 Mexico, Peru, and Brazil. The eggs are deposited in considerable 

 numbers, from 50 to 100 on each bean. It is suggested that the species 

 may in time come to infest the Southern States. 



The cabhage ciircuUo {('eutorhynchvx rajxt^ (pp. 39-50). — This insect 

 is reported as injurious to cabbage, kale, turnip, and horse-radish. Its 

 preferred native food plant seems to be hedge mustard. The author 

 describes the insect in its difi'erent stages and gives bibliographical 

 notes. In the hedge mustard the larvae cut holes through the stalks 

 as they approach maturity. Sixty or more larvse have been observed 

 in a single stem of this plant. The beetles were observed feeding 

 upon cauliflower and cabbage, eating the edges of the leaves. Near 

 AVashington the beetles appear in April and deposit their eggs, pref- 

 erably in the hedge mustard. The &gg period varies from 5 to 8 days. 

 The larva3 feed within the stems and leaf stalks and complete their 

 growth in about 3 weeks. Pupation takes place under the ground, and 

 the length of the pupal period is from 5 to 8 days. The only parasite 

 reared from this species was Omphala livida. The remedies suggested 

 include the destruction of the wild food plants of the species used as 

 trap crops, the use of hot water and bisulphid of carbon poured on 

 ground infested with larva% and the poisoning of the beetles by 

 arsenical sprays. 



Remarks on the food hahlts of species of (Jeidofhi/nchus (pp. 50-52). — 

 Brief notes are given on the host plants of certain native and foreign 

 species of this genus. 



Additional notes on the imported cahlmge wehimrin {Hellida undalis) 

 (pp. 53-61). — The first appearance of this insect in the United States 

 was in 18H5. It is probably distributed at present throughout the 

 Gulf region and is reported as very destructive in western Australia. 

 In breeding cages the larvte feed to considerable extent on shepherd's 

 purse. The insect has been reported from a number of new localities 

 in Georgia and Alabama, and notes are given on its injuriousuess dur- 

 ing the 5^ear 1899. It was reported as feeding to some extent on the 

 common garden purslane. Adult moths develop from the larva:* of 

 the first generation by July '22. The egg period was found to be 3 

 days, the larval period 18 days, and the pupal period 6 days, making 

 the entire life cycle 27 days. Three parasites were raised from the 

 webworm: JIeteo7'iis vidgaris., Teinelucha macer, and Exorista jyyste. 

 The remedies suggested are the planting of an excess of seed with a 

 view to destroying the injured part of the crop later and growing 

 cruciferous trap crops to be freely sprayed with Paris green.
