perforated by the exit of a minute Hyraenopteron, together 

 with specimens of the parasite. Mr. Walker has obligingly 

 supplied the following note on them: — "The little egg- 

 parasite is Telenoraus Phalajnariira. It is parasitic on the 

 eggs of various species of moths and of JPentatonidae. I 

 believe that all of the genus are egg-parasites. I have 

 described it and others in the ' Entomological Magazine :' it 

 belongs to the family Platygasteridae, formerly a part of the 

 Proctotrupidae." — E. Newman. 



The Army Worm. — "I was superintending the issuing of 

 weekly rations, when a gentleman came into theyard with seve- 

 ral of the well-known worms on a cotton-leaf. EJolding it up 

 before a negro man, an old hand on the place, he said, ' What 

 kind of worms are these ? ' The negro at once recognized thera 

 and exclaimed, ' Master, they are army worms ; my God, we 

 are ruined.' This worm is produced by a winged moth, which 

 flies from leaf to leaf depositing eggs, each moth depositing 

 hundreds. In from seven to ten days the eggs are hatched 

 and the worm appears. At once it begins its work, eating 

 each leaf as it goes, growing rapidly, and attaining in eight 

 or nine days its full size, about one and a half inch. It 

 then folds itself in a leaf, and passes through the chrysalis 

 slate in seven days, reproducing the winged moth, which 

 again deposits eggs, and in ten days afterwards the worms 

 swarm in myriads. These caterpillars are of two kinds, or 

 colours rather, which I fancy indicates the different sexes. 

 One is yellow, with a brown stripe down the back, dotted on 

 each side with small black spots. The other is striped brown 

 and yellow, the brown being a broad stripe extending down 

 on either side the whole length of the worm, and bordered by 

 a very narrow white line which divides the brown from the 

 yellow. They have seven pairs of legs ; one pair at the end 

 of the tail, four central pairs, and two pairs near the head. 

 By arching the spaces they crawl with a quick, measuring 

 movement, and upon being touched skip to some distance. 

 They have great vitality, and no experiment, except to crush 

 them, has been successful in destroying them. A friend 

 suggested that tobacco smoke would kill them. I filled my 

 pipe with strong tobacco, and concentrated the smoke upon 

 a lively fellow for a few minutes. He skipped about, gradually 

 sickened, was seized with black vomit, and turned on his
