well defined. Pronotum with both the humeral and anterior angles rounded. 

 Sides of pronotum without serrations. Front wings rather pointed with the 

 outer edge forming a somewhat straight line. Beneath conspicuously hairy ; 

 last ventral segment broadly rounded and somewhat truncate at the extremity. 

 In the female allotype the notch is sharp at the bottom with the sides some- 

 what sinuate. Uncus when viewed in profile hooked at the extremity. 



Head black with the supra-antennal plates orange in the type ; the allotype 

 has in addition a spot on the front and the groove behind the middle ocellus 

 dull orange. The transverse rugae black, bordered by orange, but so covered 

 with silvery hairs that the colors are considerably hidden. Pronotum black, the 

 hind margin edged with dull orange. In the allotype the front margin is also 

 narrowly edged with dull orange, and the grooves show faintly the same color. 

 Mesonotum black, bordered on the sides posteriorly with dull orange. The 

 elevated X black, touched with dull orange at top and on the hind limbs; in 

 front of the fore limbs there are the usual four orange spots arranged in a 

 semicircle. Metanotum black, edged in part posteriorly with dull orange. 

 Front wings with the venation almost black, with a submarginal dull orange 

 streak extending to the end of the radial cell. Base of fore wing blackened, 

 including the basal cell, membrane orange. Hind wings orange and dark 

 brown or almost black at base, with 'the outer veins lighter than in the fore 

 wings. Tergum black, but feebly shining, hairs silvery, uncus black. The 

 legs are irregularly striped with orange ; the femora paler at the outer joints. 

 Beneath the abdominal segments are black centrally, edged posteriorly and on 

 the sides with orange ; the last segment is broadly edged with orange. Valve 

 black beneath, orange along the upper margin. ♦

In addition to the type and allotype three males were collected at 

 Upland, California, by Miss Hewlett in 1920, as follows : June 23, 

 July I and July 5. In the Museum of Comparative Zoology, Cam- 

 bridge, Mass., there is a male collected at Claremont, California, 

 June 8, 1882. This locality is five or six miles to the west of Upland. 

 I am indebted to Mr. Nathan Banks for the privilege of examining 

 this specimen. 



While this species on account of its size, large head, rather 

 straight outer margin to the fore wings and coloring, resembles
