marks of their having been there. Indeed, by the time 

 a vine dies from the effects of their gnawings and bur- 

 rowings, the worms have generally become fully grown, 

 and have hidden themselves in their little pupal cavities. 

 So much for the two borers which have heretofore 

 been known to attack plants belonging to the Gourd 

 family. We have seen how they both bore into tlie roots 

 of these plants, and how one of them in the perfect state 

 attacks the leaves. No other borers have been known to 

 attack these plants, though the 13-Spotted Diabrotica 

 {D. 12-pu7ictata, fig. 30), may be found 

 embedded in the rind of both melons, 

 cucumbers, and squashes. But we now 

 come to a third insect which attacks 

 plants of this same Gourd family. It Fig. so.— 12-spot-

 fruit; and I have called it the Pickle Worm, from the 

 fact of its often being found in cucumbers that have 

 been pickled.

 the natural size. They vary much in appearance, some 

 being of a yellowish-white, and very much resembling 

 the inside of an unripe melon, while others are tinged 

 more or less with green. They are all quite soft and

 slightly elevated spots on each of the segments. Along 

 the back and towards the head these spots are larger than 

 at the sides, and each spot gives rise to a fine hair. The 

 specimen from which I obtained my first moth was very 

 light-colored, and these spots were so nearly the color of 

 the body as to be scarcely visible. The head was honey-
