SIXTH ANNUAL REPORT 



more than one annual brood. No. 4 {Alypia octomaculata) has eight 

 black stripes to each joint, and a series of white patches to each side. 

 It is sometimes quite abundant and injurious, and most so in the fall, 

 being double-brooded. Nos. 1, 2, and probably 3, all have an inveter- 

 ate habit of boring into wood, and other like substances, to pupate. 

 Hence, broken corn-cobs, or pieces of wood, scattered around the base 

 of the vines, may be used as traps to allure them. For No. 1, such 

 traps need be collected and burned but once a year. For Nos. 2 and 

 3 they should bo collected during summer, soon after the worms dis- 

 appear. Cleanliness in the vineyard will greatly assist in preventing 

 their injuries. With No. 4, which is not known to have this boring 

 habit, the ordinary modes of destruction in the case of leaf-feeding 

 larvcC can alone be relied on. 



Mr. Saunders has reared what he takes to be the Red-tailed Tach- 

 ina-fly (2nd Rep., Fig. 17) from No. 2. Beyond this, no parasites are 

 •known to prey upon them, though I have found lady-bird larv?e de- 

 vouring No. 1. 



THE RED-LEGGED YLKU-W^KML^—Corynetes rufipes (Fabr). 

 (Orel. CoLEorxER.v; Fain. Cleridj^). 



I thus popularly designate a 

 beetle which, from the great in- 

 jury it causes to cured hams, has 

 well earned the title. Its larva, 

 from the paper-like cocoon which

there is a very strong impression among those who know more of 

 curing hams than of natural history, that the worm is generated by 

 the rotting of the paper in which the ham is wrapped, and that it is 

 consequently, in a great measure, due to an inferior quality of paper. 



The insect has acquired more than ordinary importance during 

 the past year, from the fact that it was the cause of an interesting suit 

 for damages which was arbitrated before the Chamber of Commerce 

 of Cincinnati, in favor of the defendants. Samuel Davis, Jr., ct; Co., 

 of that city, sold a large lot of hams to S. S. Pierce A: Co., of Boston, 

 and the latter, finding most of them injured by the " paper- worm," 

 made reclamation on the sellers for damages. The defendants ob- 

 jected on the ground that the hams had been injured while in posses- 

 sion of the purchasers.
