MISCELLANEOUS NOTES. 



BY T. D. A. COCKERELL, BoULDER, CoLO. 



Genera of Dipiera. 

 Some of the generic names used for Scatopliagid?e will stand or fall 

 according to one's notion of homonymy. Becker, in 1894, proposed the 

 name Orthacheta (cf. Index Zoologicus); Aldrich, in the interest of orihog- 

 raj)hy, has altered this i^Cat. N. A. Diptera) to Orthochata. Now, 

 Germar long ago used Orthochates for a beetle, while Cossmann, in 1890, 

 nsed Orthochetus for a mollusc. I do not pretend to say what ought to be 

 done with such a mix-up ; it comes back to the old question, whether an 

 error in spelling (which may hypothetically be attributed to the printer) 

 must be maintained ; and again, if not, whether the differences in the 

 termination suffice to prevent homonymy. To the last question I should 

 answer yes, and so retain the fly, mollusc and beetle name--. 



In the same year Becker named another Scatophagid genus 

 Megaphthalma, and Aldrich (1. c ) alters this to Megophthalma. Is this 

 to be held invalid because of the earlier Megophihalinus, Curtis? 



Aldrich credits Pogonota and Okenia to Becker. It is Pogonota, 

 Zett., 1846 {Okenia, Zett., 1840, preoccupied). 



In the Blepharocerida;, Kellogg has a genus Philonis. Is this a 

 homonym of Philoros, Walker, 1854, a word with the same derivation, 

 applied to a valid genus of moths ? 



In Anthomyidfe, Tetrachceta, Stein, Berl. Ent. Zeits., 1898, p. 254, 

 is a homonym of Tetrachceta, Ehrenb. The Dipterous genus may be 

 called Parasteinia, n. n., type Parasteinia unica {Tetrachceta unica, Stein.) 

 There are several other homonymous generic names in our list of 

 Diptera ; the attention of their authors has been called to them, and it is 

 hoped that substitutes will be provided. 



Some Noctuid Moths. 

 Euxoa bn/nneigera, Grote. — Hampson remarks (Cat. Lep. Phal. IV., 

 270) that •' the form from Colorado is paler and grayer brown, the mark- 

 ings of fore wing sometimes obsolescent, the hind wing paler towards 

 base." I think this Colorado insect is a valid subspecies, which may be 

 termed E. bninneigera Masoni. The specimen before me is from Mr. J, 

 Mason's collection, and is from Glenwood Springs, Colorado. I com- 

 pared it with the excellent series of true brimneigera in the National 

 Museum, and found that it differed by the lighter and redder colour, the 

 broader primaries, and the much fainter median band. E. citricolor, 

 Grote, also occurs at Glenwood Springs (Mason collection).
