Another intermediate form has a complete subdorsal black 

 stripe, spiracular stripe incomplete, several fine much-interrupted 

 black lines between these two stripes ; an interrupted subspira- 

 cular black stripe ; a few short black lines on dorsum of seg- 

 ments 2 to 6 ; conspicuous yellowish-white transverse dorsal mark 

 on segment 5 ; head blackish on periphery, or nearly all blackish. 



Black form — Almost entirely black, less intense below ; head 

 entirely black ; a white line each side of dorsal vessel, a subdorsal 

 white line and a fainter line between it and the preceeding; sev- 

 eral crinkled white lines on sides ; more or less whitish or pinkish 

 between segments on line of spiracles, large white patch below 

 spiracle making an interrupted white subspiracular stripe ; spira- 

 cles white ; two subdorsal whTte spots on segment 5, often pink- 

 ish; segment 12 slightly enlarged dorsally and some whitish or 

 pinkish on this enlargement. Two specimens had orange-yellow 

 on middle of cervical shield, on 5th segment and on hump of 

 1 2th segment. 



Pupa — 22 mm. ; medium dark brown ; wing- antenna- and leg- 

 cases terminate roundly on apex of 4th abdominal segment ; in- 

 cisures between segments 4-7 movable ; fine punctures scattered 

 over surface of abdomen above and below, more numerous at 

 base of segments ; spiracles situated in smooth oval darker areas ; 

 cremaster inconspicuous, with four slightly diverging, ventrally 

 curved, hooked spines, the two inner ones larger. 



Pupation takes place in a cell in the soil, or beneath trash on 

 the surface. The cell is supplied with a few fibers of silk. The 

 pupal period 13-17 days. 



Hypocala velans Walker. 



Full-grown caterpillar — 40 mm. ; shorter and thicker than 

 andremona; of a fuscous-brown color which is nearly uniform, 

 but on close examination is found to be made up of dark fus- 

 cous or black with numerous crinkled longitudinal lines of a 

 lavender color ; two distinct lines border the dorsal vessel and 

 have outward angulations in the segments ; just at inner margin 

 of tubercle i in segments 5-1 1 is a small black spot, a larger spot 

 in front of tubercle ii in segments 7-10; a spot of yellow and 

 lavender mixed lies outwards from tubercle i in segments 5 and 

 12; a pale yellowish spiracular line; tubercles pale lavender 

 with a black dot at base of setae ; spiracles oval, very pale yellow- 

 ish with black margin ; cervical shield has a black longitudinal 

 subdorsal band' on each side ; head mostly black, a few pale 

 lavender spots in front and on up])cr part, paraclypeus pale, with
