special armature; the terminal claws, however, unusually long. Abdomen with a 

 loose tuft at base, otherwise dorsum untufted. Primaries short, broad, trigonate, 

 the apices well marked. 



Differs from Mamestra chiefly in the very stout body, lengthily pectinated 

 antennae and protuberant roughened front. I cannot identify it with any 

 of the genera of Hampson's monographic work. 



Miodera stigmata nov. sp. 



Head, thorax and primaries deep dark brown. Head with a scant admixture 

 of gray and black scales. Collar with a blackish transverse line. Thoracic disk 

 with an admixture of gray scales, varying in the examples; patagia with a black 

 sub-margin. Primaries with smoky and blackish shadings variably mixed with 

 gray, and with a sprinkling of yellow scales that gives a richness of color to the wings. 

 Basal line black, geminate, interrupted on the sub-costa. A short black basal dash 

 that just reaches the t.a. line. T.a. Une geminate, black, the included space some- 

 times lightened by yellow scales, in course outwardly oblique, with three moderate 

 outcurves. T.p. line geminate, black, abruptly bent out below costa, then almost 

 parallel with outer margin; the inner line lunulate and usually, at least, traceable 

 across the wing, the outer more even and usually lost below the cell. S.t. line more 

 or less yellow, variably defined by darker preceding or foUowng shadings, with a 

 well-defined W on veins 3 and 4. A lunate black terminal line followed by yellow 

 venular points at the base of the long interlined fringes. Claviform a small but con- 

 spicuous black loop. Orbicular round or nearly so, moderate in size, concolorous, 

 ringed with yellow scales. Reniform large, upright, a little constricted at middle 

 and expanded below, inferiorly black-filled, the upper half paler, and edged with 

 yellow scales. Between the spots the cell is darker or even blackish. Secondaries 

 smoky yellowish, with a discal lunule, a somewhat waved extra-median line and a 

 distinct blackish terminal line. Beneath, gray, powdery, -s^ith a narrow, distinct 

 extra-median black shade line crossing both -nings. All wings with a discal spot and 

 a lunate marginal line. Abdomen like secondaries in color. 



Expands 1.04-1.14 in. = 26-28 mm. 



Habitat: Witch Creek, Cal., Jan. 12-Feb. 3. 



Ten males, in good or fair condition. This is a well-marked and rather 

 pretty species somewhat resembling Mamestra ectypa, and it does not appear 

 to vary to any considerable extent. 



Tseniocampa macona nov. sp. 



Ground-color of head, thorax and primaries, creamy to luteous gray. Head 

 and thorax without maculation. Primaries more or less powdered with black atoms, 

 and veins tend to become pale. Basal line geminate, broken, usually marked by 

 black spots on costa and median vein. T.a. line outwardly oblique, even, of the 

 ground-color or paler, marked on both sides by black scales so as to define the entire 

 line in the best case, but so irregularly in others that it may become entirely lost
