A New Catocala Net. 



By J. C. HUGUENIN, San Francisco, California. 



Collectors of Catocala will undoubtedly be interested in a 

 new net for their special use. My experience and difficulty in 

 gathering these moths is, no doubt, shared by others, and I de- 

 termined on perfecting a net that would obviate many difficul- 

 ties and preclude the possibility of losing a good specimen. 



As all CaYora/a-collectors are aware, many of these moths 

 repose in crevices in bark quite out of reach of the collector. 

 With the serrated rubber edge (D in the diagram) the ob- 

 stacle offered by the breach in the bark, which provided a 

 refuge for the moth, can be overcome. The flexible teeth of 

 the net D enter all the uneven surfaces of the bark and a 

 slight movement of the net is sufficient to cause the moth to 

 fly. The teeth prevent the moth escaping along the crevices 

 in the bark. The alternative is flight, and in so doing the moth 

 enters the cyanide bottle through the paper funnel B where, 

 owing to the peculiar construction, escape is impossible. 



The maker of this net has been able to catch Catocalac with- 

 out effort at a height of 12 to 14 feet from the ground. 



The figure on the following page shows the construction ot 

 the net so that only a few words are necessary in explanation. 



A cyanide bottle 2.y 2 x 5 inches showing the position and 

 style of paper funnel B. 



B Paper funnel made of light, stiff paper ; the funnel is 

 glued to the interior of the cyanide bottle at the mouth. 



C- Light wire screen funnel through which the actions of 

 moth can be observed. 



D Metal net frame, 6 inches in diameter, with serrated edge 

 made of rubber, one and a half inch wide, teeth cut so that 

 they will be about one inch long. 



E Light metal (galvanized iron) clasp entirely surround- 

 ing the bottle to hold the bottle rigidly against the net.
