364 ENTOMOLOGICAL NEWS [Oct.. '13 



I have an Arizona male which I have compared with all the 

 above types, and the evidence seems much in favor of their all 

 being one species, though I do not feel sufficiently sure of it to 

 venture the direct reference at present. My own specimen has 

 certainly the frons of Euxoa. 



A very distinct species appears to have been mixed up with 

 biclavis, probably by Grote himself. Of this there are a male 

 and two females in the Henry Edwards collection from the 

 Colorado Desert, and a series in the U. S. National Museum. 

 It is a species allied to lagena Grt., about the same size, and 

 with similar male antennae, that is. ciliate only. 



Hadena devastatrix Brace. 



Hampson places this in the genus Sidemia Stand., the only 

 other North American species which he makes congeneric with 

 it being longula Grote. Sidemia finds a place in \^olume vii 

 of the Catalogue, the first of three volumes devoted to the 

 Acronyctinae, a large subfamily characterized by the trifid 

 neuration, combined with spineless tibiae and smooth eyes 

 not surrounded by bristle-like hairs. But as I have pointed out 

 in Can. Ent. xHii, 233, July, 191 1, and also in a former note in 

 the present paper under Polia speciosa, devastatrix has not in- 

 frequently a spine or spines on the hind tibiae. Had Sir George 

 Hampson noticed this, he would presumably have treated the 

 species in Vol. iv. 



During my recent visit to the British Museum I noted the 

 strong superficial resemblance of devastatrix to the European 

 ahjecta Hbn., which Hampson makes a synonym of ohlonga 

 Flaw., and refers to genus Trachea Ochs. in the same volume. 

 I examined many of the specimens of abjecta carefully, and 

 found that several of them had hind tibial spines. Until then 

 I had overlooked the fact that Guenee had treated devastatrix 

 as a variety of ahjecta, and that they are considered synonym- 

 ous in Staudinger's Catalogue, and given a wide distribution 

 in the Northern hemisphere. The descriptions I have read 

 of the larvae of the two sound a little diliterent, and that of 

 ahjecta is said to confine itself closely, in Britain, to grasses 

 growing on salt marshes and tidal estuaries. In this country,
