THE CANADIAN ENTOMOLOGIST. 63 



question of the types to be discussed some 60 or "jo years hence, with no 

 more definite knowledge on the subject to assist the inquirer than 

 the Stephensian types and the Slephensian descriptions would supply ; 

 might it not be argued that the types (in the cases under discus- 

 sion) must be ignored, as they never could have been intended to 

 represent the true Loppa pulicaria, Steph., because they are antagonistic 

 to the description f " 



Again, quoting Dawson : " Dr. Schaum invariably refers to the 

 Stephensian types ; my references are frequently given to Stephens's 

 works, irrespective of the types. Now we are well aware that these do 

 not always correspond, but that, on the contrary, considerable difference 

 is often to be found between them. 



" Before the Linnean collection was placed in its present quarters, it 

 was so maltreated by additions, destructions and displacement of labels, 

 as to render it a matter of regret that it now exists at all." 



I must express my astonishment that the author of this Revision 

 should have undertaken to overturn the work of two generations of 

 entomologists, and to mix up several species as one by reference to a 

 single type insect, taken 64 years ago, represented, as he should at once 

 have seen, by a bogus specimen ! 



The description of Curtis, on which is our sole reliance, applies 

 closely and almost exactly to the species taken at Laggan, and to which 

 Mr. Elwes gives the name of Beanii. It is sub-hyaline, as much and 

 perhaps more so than C. Brucei. It is pale black, and it has the 

 faded and worn appearance mentioned by Curtis, particularly so by its 

 clouded and smoky underside. I'he other markings agree well with his 

 description. I described this species as Subhyalina, Curtis, in Can. 

 Ent., XXV., p. 137, 1893, and in Part 15, Vol. 3, B. N. A., it will be 

 fully illustrated. The reading of this so-called Revision convinces me 

 that I was and am right.

In Part XIV. I gave the series of the American species thus : i 

 Crambis ; 2 Brucei; 3 ^no, and its var. Assimilis: 4 Semidea ; 5 Sub- 

 hyalina; rejecting Also as not American, and I hold to this to-day.
