liuinlcs. Secondaiies blackish fnscons, with pale friuges. Beneath 

 ihulc, powtleiy, with iiulistinct discal lunule. Jlead and thorax con- 

 coh)r()iis wMth i)riinaries, the latter with indistinct fore and aft tufts. 

 Abdomen with a distinct truncate tuft on the basal segment. Expands 

 1.40 inches (35'""'). 



Ilahita f. — Colorado. 



The tyi)e from Mr. Hulst is a 5 in fair condition. The vestiture is a 

 mixture of scales and flattened hair, and the thor;ix in form is quadrate. 

 The frontal vestiture forms two superimposed tufts. The species seems 

 rather closely allied to Mamestra while differing obviously in habitus 

 from anything in that genus. It agrees with suhmarina \u the peculiar 

 modification of the last ventral segment, which is carinate at middle 

 and foveate at each side. 



S. umbrosa Sniitb, sp. nov. 



Primaries dark, blackish gray, powdered with white scales. All the 

 maculatiou present, though not prominent. Median and basal lines 

 geminate, the defining lines faintly marked, included space powdered 

 with wiiite. T. a. line outwardly oblique, with inward dentations on 

 A^eins, T. a. line about parallel with outer margin, tolerably even. S. t. 

 line irregular, pale, punctiform, somewhat obscured by the palepowder- 

 ings, which are most numerous in the s. t. s])ace. An interrupted dark 

 terminal line. Claviform distinctly outlined, concolorous Orbicular 

 moderate, round, with white powderings. Reniform large, upright, 

 pale powdered, well defined. Secondaries blackish, paler towards base. 

 Beneath variably dark, powdery, with outer dark line and small discal 

 spots. Head and thorax concolorous with primaries. Expands 1.20- 

 1.30 inches (30-32"""). 



Habitat. — Arizona, Colorado. 



Three 2 specimens from as many collections are before me. The ves- 

 titure is scaly, and the tufts of thorax, abdomen, and front are like 

 those of inconGinna. There is no special modification of the last seg- 

 ment of the abdomen.

INIr. (hote sei>arates this genus from Mamestrahy the armed fore tibia. 

 This armature in the htiiry eyed genera is so unusual that it obtains 

 great value, and, added to the very peculiar genital structure of the S, 

 which is not ]>aralleled in any species of Mamestra examined, it seems 

 to us that the genus is a valid one. The European species M. hrassicea 

 is the type. C. occidentalis was collected in New Mexico, and now Mr. 

 Thaxter sends a new species from Maine, very closely allied to hrassi- 

 cea, but structurally different. 



C. curialis Smith, sp. nov. 



Primaries blockish fuscous, with a reddish tinge through basal and 

 s. t. spaces, slightly marked also through center of median space. Basal
