says: "Walker's type is in the Britisli Museum, and is like the 

 2)erangiilalis of the Grote collection, and of American collections 

 generally." 



Now the type of Walker's H. damnosalis is neither more nor 

 less than the female of H. caducalis, and, therefore, differs from 

 ]I. perangulalis of the Grote collection in its shorter primaries, 

 shorter palpi, in having entirely different markings, the two 

 lines across the primaries not edged with white, the outer line 

 undulated instead of simply subangulated. The H. j^erangnlalis 

 of the Grote collection, in fact, differs chiefly from the //. decep- 

 talis of the same collection in its lighter colouring and its sex. 

 It is a female, and is, in my opinion, unquestionably the female 

 of //. deceptalis. Strictly speaking, I should say that H. decep- 

 talis, being much more nearly related to //. j^'i'ohoscidalis than to 

 the typical forms of Bomolocha, might be called a true Ilypena.*' 



Professor Smith had the disadvantage, in the case of the 

 Hypenidfe, of working with the Walkerian arrangement, still 

 more confounded by subsequent accessions; and when he got 

 down to these he was pressed for time. It would be odd, 

 therefore, if he failed to make any mistakes in his synonymic 

 notes ; even the best workers, when hurried, are not infallible. 



OBSEEVATIONS ON THE HESSIAN FLY {CECIDOMYIA 

 DESTRUCTOR) DUEING 1893. 



By Fred. Enock, F.L.S., F.E.S. 



I HAVE often been asked : " How is it that we hear so little 

 about the Hessian Fly now ? " " Is it exterminated from Great 

 Britain ? " " Do you think it really does any damage to the 

 crops?" &c., SiC. The following facts will be the best answer 

 to these queries. 



In Great Britain so little interest is taken by the public in 

 Economic Entomology that we must not be surprised to find that 

 editors of newspapers are unwilling to find room for short accounts 

 of the occurrence of these pests, the doings at " Jobn Barleycorn's" 

 being of far more interest to general readers than those of the 

 Hessian Fly in the barley cornfields : in one, the Homo species is 

 apt to get injured and unable to bear his weight, and when found 

 suffering from weakness at the joints, he is looked after and taken 

 care of; but in the case of the species destructor injuring the crops 

 and causing them to bow their bearded heads low on the ground, 

 none but the farmers feel any the worse for this pest ; and even 

 they, though quite aware that " summat has got their crops," do 



* That isj if Staudiuger is right in associating H. prolosciclal'is with H 

 rostralis.
