THE CANADIAN ENTOMOLOGIST. 



Types : University of Kansas and my collection. 



Placed in Plutella tentatively; agrees with Meyrick's definition, except 

 that 3 and 4 hind wings are not approximate, the palpi are tufted above 

 and not beneath. 



Genus Dorota, Busck. 



The moths of this genus superficially resemble Crambids, on account 

 of their long, extended labial palpi ; so far they have only been taken in 

 Arizona and California, and only a very few specimens are known. 



I have a fine specimen of lineata, Wlsm. {virgatella, Busck), from 

 Cochise Co., Ariz., June 4, 1904, from Geo. Franck, and two very dis- 

 tinctly marked species, which are described below. The four known 

 species can be separated by the following table : 



Fore wing with lighter median streak i. 



Fore wing without lighter median streak 2, 



1. Ground colour light ochreous-brown =medioliniella. 



Ground colour ashy-gray = albastrigulella. 



2. Fore wing marked with darker lines =lineata. 



Fore wing not marked with darker lines = inorratella. 



'Dorota medioiiniella, sp. nov. — 9. Expanse, 27 mm. 



Palpi, head and thorax pale yellowish-brown, speckled with gray- 

 brown ; palpi long, about 4 mm., porrect, outer joint sharply bent down- 

 ward. 



Fore wing 35^ times as long as broad, lanceolate, pale yellowish- 

 brown, a paler creamy-white streak from base to apex, interrupted at end 

 of cell with a few dark scales, with a darker geminate-blackish streak above 

 it. A slightly darker shade above dorsal margin, and a cluster of dark 

 scales on fold at inner third. 



A number of black dots are scattered over the wing, notably a line of 

 eight on inner half close to costa, becoming more widely separated out- 

 wardly, one on upper edge of dark streak near apex, about eight in 

 pale streak, about fifteen in three irregular horizontal rows on outer third 

 below middle, four of which are in the cilia, a line of six in two groups of 

 three above fold in middle of wing and one above the fold. Extreme dorsal 

 edge dotted with brown scales. 



Hind vving, fuscous-gray, slightly shining, cilia same. Under side 

 both wings fuscous-gray, with a brassy tinge. Abdomen same, anal tuft 

 paler. Legs cream-white. 



One specimen, Claremont, Cal. No. 3889. C. F. Baker. Type in 

 my collection.
