March, 1898.] DVAR : NEW NORTH AMERICAN MOTHS. 41 



Three examples from Walsh collection, U. S. Nat. Mus. 



NOCTUID^E. 

 Cydosia Wesiwood. 



New synonyms of this genus are Penthetria Hy. Edvv. and Tantura 

 Kirby. C. majuscula, the type of the genus, belongs toCydosla. Neu- 

 moegen and Dyar placed it in the Lithosiidse, but ocelli are distinctly 

 present, as I have proved in fresh material. We could not examine the 

 type freely, so failed to discover them. 



The other species of Penthetria, namely parvula, from Florida, is a 

 Tineid forming a curious pedunculate, lace-work cocoon. It is at pres- 

 ent without reference to any genus. 



Synopsis of forms of Cydosia. 



Primaries with three golden brown bands. 



Many white spots on wing and thorax nobilitella Cr. 



Without white spots aurivltta G. R. 



Primaries without any markings majuscula Hy. Edw. 



Euclidia diagonalis, sp. nov. 



Pattern of markings as in E. intercalcaris Grt., but the pale mark that arises 

 near the anal angle is directed to the outer third of the cell instead of joining the 

 pale reniform as in the allied species. Other markings similar but rather more 

 drawn out longitudinally. A black streak runs through the cell, obscuring the puncti- 

 form orbicular. The white t. p. line is rather diffuse and shaded, straight, joining 

 the oblique mark below. Expanse, 44 mm. 



One 9 , Mesino Valley, New Mexico (Wheeler Survey, through A. 

 S. Packard). Type No. 3844, U. S. Nat. Mus. 

 Apatela minella, sp. nov. 



Closely allied to A. fragilis Guen. but uniformly shaded with dark gray. Head, 

 thorax and fore wings blackish gray, the lines as in fragilis, the centers of t. a. and 

 t. p. lines whitish and rather contrasting. Ordinary marks outlined in black, the 

 basal dash indicated. Abdomen dark gray; secondaries scarcely darker than in 

 fragilis. 



One? . Type No. 3843, U. S. Nat. Mus. 



The specimen is without locality label, but probably from Rocky 

 Mountain region. 



This may be a western form of fragilis. 



NOLID^E. 



Following Dr. Chapman's views on the phlyogeny of this group, I 

 place them as a distinct family at the bottom of the Bombyces or between 

 the Bombyces and Tineides. The larval characters correspond with this
