mere aberration in which the primaries are distinctly paler and the 

 brown band beyond the t. p. line more marked in consequence. 



Catocala beutenmuelleri B. & McD. 



Ovum. Flat, strongly ribbed; micropylar area forms a slightly raised button 

 with central depression containing the micropyle itself; from the rim of this area 

 17-20 broad unbranched ribs arise, crossed at right angles by numerous fine wavy 

 cross-ribs. Color purple with yellow ring a short distance above the base. Diam- 

 eter, 1 mm. 



Stage I. Head black. Body pale gray with 3 brown lateral stripes; diffuse 

 brown patches laterally on 1st four abdominal segments with traces of a 4th brown 

 line posterior to them; below these a 5th subspiracular line; tubercles black, small, 

 with long seta?. Beneath pale with central dark blotches. Length, 4 mm. 



Stage II. Head pale gray, heavily mottled with brown except in front and with 

 two heavy dark curved lines below apex of lobes not reaching lower than apex of 

 clypeus; five equidistant lateral and subspiracular lines as before, the 3rd line rather 

 waved, the lower line distinct; dark lateral abdominal patches much fainter than 

 in preceding stage; dorsal region with two brown lines narrowing between tubercle* 

 I and spreading out towards rear of segments tending to form diamond-shaped 

 patches of the enclosed space; traces of a centro-dorsal line between tubercles I 

 on abdominal segments; on oth abdominal segment a slight raised dorsal wart; 

 on 8th abdominal a sma'l conical projection; tubercles black with setae as before. 

 Length, 9 mm. 



Stage III. Head as before but more striate with black. Body and markings 

 essentially as before but pale dorsal diamond-shaped patches more noticeable and 

 the dark lines appearing more as border lines to enclosed yellowish stripes; small 

 transverse wart on 5th abdominal segment; the rear portion of this segment and 

 anterior portion of 6th shaded with blackish; 8th segment raised dorsally with 

 conical reddish tubercles and a small black lunate mark posterior to these; pro- 

 legs with black stripe. Length, 15 mm. 



Stage IV. Head pale, strongly marbled, apex of lobes slightly orange, below 

 which is a small blackish curved mark; behind the apex of lobes a curved double 

 black line extending laterally down the sides of the cheeks. Body gray, somewhat 

 ochreous at the incisions of the first four abdominal segments; lines and stripes 

 much as before but fainter, the former being broken up into a series of dots; tub- 

 ercle on 5th abdominal segment black, prominent, with dirty brown oblique patch 

 extending laterally downwards to base of prolegs; tubercles deep orange, those on 

 8th abdominal segment situated on a strong hump behind which is a curved orange 

 mark; prolegs pale, striped with black; beneath whitish with the usual black 

 patches. Length, 25 mm. 



Stage V . Head purplish gray marbled in the front of the lobes with darker; 

 the two tubercles at the apex of the lobes tipped with orange with dark blackish 

 curved mark behind the apex. Body light gray, fairly smooth, with small oblique 

 ridges on the anterior abdominal segments extending laterally forward from tuber- 

 cle II; pale dorsal stripe with diamond-shaped enlargements; remainder of body 

 heavily marbled with black dots, representing the dark bonier lines of previous
