been mentioned and by the publication of " The Revieiv of Applied 

 Entomology,'' it will furnish a means of assistance and of co-ordina- 

 tion of effort in the war against noxious insects, which will un- 

 doubtedly soon make its services invaluable in the further de- 

 velopment of the countries, and especially the tropical and sub- 

 tropical countries, of the British Empire. International, as the 

 scope of its inquiries are, the work of the Bureau cannot but prove 

 to be one of the most potent factors in enabling us to develop the 

 agricultural and other resources of the Empire, and our fellow- 

 workers in non-British countries can avail themselves, throug this 

 journal, of some of the fruits of the Bureau's work. 



GEOMETRID NOTES.— A NEW VARIETY. 



BY L. W. SWETT, BOSTON, MASS. 



Therina fiscellaria Gn., var. Johnsoni, Nov. — Expands 30 m.m 

 Fore wings smoky ochreous instead of being yellow as in the normal 

 form.^ The fore wings are smoky to the basal band, which shows 

 as a bright ochreous line, crossing from costa to inner margin in a 

 regular curve. The mesial space is smoky, with black discal dot 

 showing faintly through. Extra-discal line bright ochreous, curved 

 from costa to median vein, then back sharply in a deep curve to 

 inner margin, as in normal fiscellaria. Beyond the wing is smoky 

 black to outer margin. Fringe short and smoky ochreous. An- 

 tennae and head ochreous; body of the same colour. Hind wings 

 smoky ochreous to extra-discal line, which rounds out to a point 

 opposite the black discal spot, the line being ochreous as on the fore 

 wing. Beyond the extra-discal line the wing is smoky to outer 

 margin. The insect, on the whole, seems rather semi-hyaline in 

 appearance, and is no doubt a melanic form. Beneath the fore 

 wings are much lighter than above, with the markings showing 

 through. Hind wings lighter than above, almost a dark fawn 

 colour, with lines showing through from above. 



This seems to be a rare form and quite distinct from an>' 

 described variety. I take pleasure in naming this variety after 

 my kind friend, Mr. C. W.Johnson, who has rendered me valuable 

 help and suggestions.
