296 EEPORT UPON COTTON INSECTS. 



the fruit of the tomato. As we have already shown-(American Entomologist, i, pp. 

 212, 213), this same species attacks our corn, and does great damage to our tomatoes 

 by eating into the fruit; and the fact of its being bred from the tomato in England, 

 "where this fruit is with difficulty grown, is interesting and suggestive. 



But the tomato- worm is not confined to the fruit, as is shown by the 

 fact that several specimens were recently sent to the department, with 

 the remark that they were found boring into the terminal shoots of 

 tomato plants at Macon, Ga., early in September. 



Another common garden vegetable that is also injured by the boll- 

 worm is the garden pea. We extract the following from the American 

 Entomologist, ii, pp. 42, 43 : 



From the following passage in an address on insects, delivered at Vineland, N. J., 

 by that excellent observer, Mrs. Mary Treat, of that place, and published in the Vine 

 and Weekly of August 21, 1869, it appears that this very same larva also feeds upon 

 the undeveloped tassels of corn and upon green pease. 



"This year, green pease have been eaten into by a hatefullooking worm, and a simi- 

 lar one ate into the staminate flowers of the corn before it tasseled out, commencing 

 their depredations while the tassels were still enfolded in the leaves. I have exam- 

 ined considerable corn, and in some gardens this worm has done much damage. While 

 feeding, it is of a green color; bnt when it comes to full size it turns brown, and goes 

 into the ground to assume the chrysalis form. I already have the moths of the cater- 

 pillar that lived upon the pease, and am waiting for those that lived upon the corn to 

 make their appearance, so that I may decide whether they are distinct species. It is 

 a query with me what the second brood of caterpillars will live upon as green pease 

 and untasseled corn will be out of their reach. " 



There can be no doubt about the identity of the moth, the larva? of which fed upon 

 pease, because Mrs. Treat obligingly forwarded to us in the middle of August specimens 

 actually bred by her from green pease, which differ in no respect from the common type 

 of the corn-worm moth. Unfortunately, she has mixed together promiscuously the 

 moths bred by her from green pease and those which she subsequently bred from corn 

 tassels ; but at our express desire she has examined the mixed lot, and informs us that 

 she can detect no difference of any consequence among them. 



Testimony to the same effect has been given by Mr. Glover (Depart- 

 ment of Agriculture Report 1870, p. 84) and by Mr. Riley (Third Mis- 

 souri Entomological Report, p. 105). Mr. Trelease observed them eating 

 garden pease in Alabama. A boll-worm would bore a hole into the pod 

 and devour its whole contents before leaving it for another. 



Of allied plants, the boll-worm has been observed to eat the chick-pea 

 (Cicer arietinum) in Europe, the common cow-pea of the South, and the 

 common string-bean (Phaseolus vulgar is), and Erytlirina herbacea, a le- 

 guminous plant common in the South. M. J. Fallou (Insectoloyie Agri- 

 cole, 1869, p. 205) records Heliothis as feeding upon the chick-pea, lie 

 found the young worms to feed upon the leaves and the large ones to 

 bore into the pod. With the cow-pea, upon which Mr. Trelease found 

 it feeding very abundantly, and in which the pod is more fleshy and the 

 pease separated by lleshy partitions, it often pursues a different course 

 from that which it takes with the common garden pea; it often bores into 

 one chamber of the pod, eats the seed in it, and then, instead of cutting 

 through the partition to reach the next, bores another hole from the out- 

 side. The same observation precisely was made concerning their habits
