2 THE CANADIAN ENTOMOLOGIST. 



the ten years that have now gone by, he has done an enormous amount 



of valuable work, as shown in his annual reports and evidence before the 



Standing Committee of the House of Commons on Agriculture., his 



voluminous correspondence with farmers and fruit-growers all over the 



Dominion, and his addresses to Farmers' Institutes and other gatherings. 



No one in this country has done so much as he to instruct the people in 



a practical knowledge of their worst insect foes and the best methods of 



dealing with them, while probably no one but he could have given the 

 Province of Manitoba the information and the advice that he has repeat- 

 edly afforded by his lectures, addresses, and publications on the noxious 

 weeds of that portion of the Dominion. All his friends will, we are sure, 

 unite with us in the earnest wish that he may long be spared to carry on 

 his admirable work, which is of such vast importance, not only to those 

 directly interested in the products of the soil, but to all the dwellers 

 throughout this wide Dominion. 



A GENERIC REVISION OF THE LACHNEID^ 

 (LASIOCAMPID.^:). 



BY HARRISON G. DYAR, WASHINGTON, D. C. 



The genera of the same regions are included in the present paper as in 

 a former one on Hypogymnidae (Can. Ent., XXIX., 12). The palsearctic 

 Lachneids of the old world have been admirably treated by Aurivillius 

 (Iris, Dresden, vii., 1 21-185), ^^^ I ^^ indebted to his work for valuable 

 information, as well as to the works of Kirby and Hampson. In going 

 over the literature I did not always confirm Kirby's types of the genera ; 

 but rather than disturb the matter again, I have accepted them as 

 modified by Aurivillius; but with the restoration of Habner's Tentamen 

 names, I drop Gastropacha, as it is a synonym of Lasiocampa, being 

 proposed in the same sense to include all the species of the family. 

 Following Wallengren, I separate catax and rimicola from Eriogaster as 

 defined by Aurivillius for convenience in the table, though I do not doubt 

 that the venation is as variable as Aurivillius states (Iris, vii., 147). I 

 cannot separate the new genus Paralebeda, Auriv., from Odonestis by 

 anything that is stated. 



The oldest plural term for the family is again Hiibner's Lachneides, 

 and must form the family name as shown by Grote.
