stages; a very prominent fleshy beak-like wart on 5th abdominal segment shaded 

 with black and with black posterior markings extending obliquely downward over 

 the anterior portion of the following segment; laterally the 5th segment is shaded 

 with light brown extending between the prolegs on to the Cth segment; prom- 

 inent conical dorsal tubercles on the 8th abdominal segment with lunate brown 

 mark behind extending to above spiracle; filaments whitish; beneath white with 

 central black blotches. Length, 40 mm. 



Food-plant: Buds and catkins of oak. 



The larvae emerged about a week later than zoe and aholibah 

 maturing rather more slowly than these two species; a number 

 of the full grown larvae refused to pupate but gradually shrivelled 

 up and died; it is probable that better results would be obtained 

 by isolating the larvae in the last stage. The prominent dorsal 

 wart on the fifth abdominal segment would place the species in 

 the ultronia group. In our opinion beidenmuelleri will prove to 

 be a local race of verrilliana but we can find no larval description 

 of this species. We cannot agree with Hampson who makes this 

 species and werneri Bied. synonymous; this latter species, of which 

 the type is in Coll. Barnes, shows much more affinity to violenta 

 Edw. and we should not be surprised if it proved to be a mere 

 aberrant form of the same; ophelia Hy. Edw. we have proved by 

 breeding to be a species very distinct from beidenmuelleri and 

 presumably therefore from verrilliana; breeding alone will show 

 how closely it is related to violenta Edw. 



Catocala ophelia Edw. 



Ovum. Hemispherical, much higher than beutenmuelleri; ribbed, about 20 ribs 

 attaining the edge of the raised circular micropylar area, every second rib branch- 

 ing dicotomously in contradistinction to the preceding species where the ribs always 

 remain single; color liver-brown with yellow ring near the base. Diameter, 1.2 mm. 



Stage I. Head blackish; body blue-gray more or less completely banded with 

 brown on the first four abdominal segments, tending to form lateral and dorsal 

 blotches; tubercles black with long black setse; geminate rather waved dorsal 

 brown lines situated in the area between tubercles I and II and tending to separate 

 towards rear of each segment; three lateral brown lines and two further subspirac- 

 ular ones. Beneath whitish with brown central patches. Length, 6 mm. 



Stage II. Head pale gray, marbled with black with inverted V shaped black 

 mark on front of each lobe and central black dash on clypeus. Body pale yellowish 

 gray with black tubercles and traces of lateral purplish patches of previous stage; 

 markings as before with the addition of a centro-dorsal broken stripe, thickened 

 slightly at intervals. Length, 11 mm. 



Stage III. Head same as before. The lines on the body of the previous stage
