THE CANADIAN ENTOMOLOGIST. 137 



The hitherto universally-accepted family, Elacliistidce^ Lord Walsing- 

 ham finds inseparable from the Hypo?iomeutidce, through the knowledge of 

 intergrading Hawaiian forms. AVhile agreeing that any divisions which 

 cannot be well defined should be avoided as inexpedient, though not 

 necessarily unnatural, the writer is not quite prepared for this radical 

 move, and ventures to suggest that the final solution of this question has 

 not been reached, and may be found, rather, in other limits being drawn, 

 than in no limits between the two families. 



In the Hyponomeutidce^ Lord Walsingham further places Blastobasis 

 and Efidrosts, though he has himself, within the last year, elucidated the 

 family Blastobasidce by a generic table, in which he included both these 

 genera (Proc. U. S. Nat. Mus., XXXIII, page 200, 1907). 



No reasons are advanced for this change of view, and it can only 

 be explained on the supposition that this part of the work had been 

 written some years ago, and has not been brought up to the author's 

 present conception. The Blastobasidce^ in the absence of proof to the 

 contrary, should be retained as a natural and easily - defined family, 

 characterized mainly by the peculiar venation of the forewing. 



The genus Endrosis, however, does not, in the writer's opinion, 

 belong to this family,* but to the CEcophoridcE, near Borkhausenia. 



After these radical reductions in the number of families. Lord Wal- 

 singham, on the other hand, promotes to family rank the Carposiriidce^ 

 as suggested by the writer (Journ. N, Y. Ent. Soc, XV, p. 35, 1907), in 

 which he presumably will include the Fkaloniifice as a sub-family. With 

 equal propriety he retains the Oiethretiiifice and the Tortricince under one 

 family heading, Tortricidce. 



He adheres to the idea, which he originated, of placing these fami- 

 lies between, rather than in front of, the other families of the Tmeina^ 

 which seems the more warranted in view of Meyrick's recent intermediate 

 family, Chlidatiotidce (Journ. Bom. Nat. Hist. Soc, XVII, page 412, 

 1906); but it must be kept in mind that the Tortricidce are a terminal 

 branch, from which no other family has developed. The writer regrets 



*Nor does Arctoscelis, Meyrick. In his g-eneric table, above-mentioned, 

 Lord Walsingham differentiates these two genera on the character : no anten- 

 nal pecten, a character which, if true, alone would tend to eliminate them from 

 the family ; Endrosis, however, possesses a very strongly-developed pecten.
