the propleural flap deeply depressed beneath the carinate margin, and broadly in- 

 dented above the coxae. Legs dull testaceous, the spines black, and the posterior 

 femora marked with lines of brown dots. Scutellum highly polished, moderately 

 convex, obsoletely minutely rugulose, entire, subacuminate at tip. Hemelytra wide, 

 minutely, remotely pubescent, darker upon the disk than upon the margins, the 

 clavus rather coarsely punctate, the corium obsoletely punctate, but a little coarsely 

 so at base ; the costal margin feebly curved, sharply reflexed, pale, becoming gradu- 

 ally wider behind, and at the outer angle jutting beyond the base of cuneus ; the 

 cuneus pale across the base and upon the margins, the tips acute ; nervules of mem- 

 brane pale, the membrane sometimes clouded at base and tip. Venter dusky from 

 base to just before the last segment, excepting the connexivum, the edges of the seg- 

 ments testaceous. Sternum sometimes with a dark band across the middle. 



Length to tip of venter 2\ — 3 mm.; to tip hemelytra 3 — 3^ mm. Width of base 

 of pronotum 1 \ — 1 \ mm . 



The dark variety of this species has been captured in the highlands 

 of Georgia. 



Notes on certain North American species of the group 



called by M. Guenee 'Acronycta'. 



By A. G. Butler, L. L. S., L. Z. S. 



I propose, from time to time, whilst incorporating the Grote and 

 Zeller collections with the series in the British Museum to publish a few 

 critical notes on the various types or co-types in our possession : the fol- 

 lowing notes, which are not based upon on my individual judgment alone, 

 but are supported by the opinion of a co-worker, are I believe absolutely 

 correct. 



When Messrs. Grote, Robinson and Riley examined our collections 

 they neither had time or opportunity to examine the whole of the speci- 

 mens in the British Museum, Grote and Zeller collections side by side 

 (i. e. placing the types together upon one piece of pith and critically com- 

 paring both surfaces) and therefore it was not to be expected that their 

 published notes should be final. 



A. brumosa, Guen. 



We possess the types labelled by M. Guenee from W. Doubleday's 

 collection : one of them — the type of the species— is labelled simply 'Acr. 

 Brumosa, Gn.'\ it agrees perfectly with the type of Apatela persuasa Har- 

 vey, in Grote's collection ; the other specimen is labelled 'variety Acron. 

 Brumosa. Gn.' and agrees with the type of Acronycta afflicta, Grote. 



The A. brumosa of Grote's collection is therefore not Guenee's species 

 but is = A. veri/lii, Grote, = fusciata, Walk., = impressa, Walk., as 

 pointed out by Grote.
