ON THE GEOGRAPHICAL DISTRIBUTION OF SOME GENERA OF CANADIAN INSECTS

Francis Walker
1873 Canadian Entomologist  
Before leaving the CanadianChalcidiæ, in hope of returning to them when many more genera are discovered in Canada, I will mentionMegastigmus, which very probably occurs there; it is a genus ofTorymidæ, and, in some respects, connects that family with theEurytomidæ, and is next to the latter in the interest with which it may be regarded in case there is a foundation for the report lately published concerning the seed-eating habits of the species which represent it in California.
