The Squash Bug. Coreus tristis, De Geer. Family, 

 Corcidce. Order, Hemiptera. This old-time enemy is so well- 

 known that the figure is all that is necessary to bring his image 

 and evil doings to mind. 



NATURAL HISTORY. The squash bug, in common with all bugs, 

 passes through partial or incomplete transformations, by which 

 we mean that they are quite alike at all stages of growth, so 

 that usually, at any stage of growth, the species would be recog- 

 nized by even the unskilled in entomology. The larva, unlike 

 the caterpillar, the grub, and the maggot, is so like the imago that 

 the relation of child and parent is easily recognized. The ma- 

 ture insect (Fig. 11) hibernates during winter, but 

 by the time the melon, squash, or pumpkin vines 

 are well up, their dusky forms, ocher yellow be- 

 neath, may be seen feeding on the leaves by day, 

 and hid under some chip, clod, or in some crevice by 

 night. Soon the brown eggs are laid in clusters

 greenish larvae, which soon become grayish, which hatch from 

 these, commence a thorough work of despoliation, in which they 

 are aided by their parents, which seem unwilling to die with so 

 much good provision at hand. After a time, stubs of wings 

 appear, which, with increased growth, is all that serves to dis- 

 tinguish these pupae from their former larval condition. Nor 

 can these afford time for quiet, like most pupae. On the other 

 hand, they continue to gorge themselves with the juices which 

 they suck from the plant. Soon they attain full growth, and 

 fully developed wings, and are called imagos. These images 

 live through the winter, and are ready to repeat the same ruin- 

 ous work another season. 



REMEDIES. The habit that these squash bugs have of con- 

 cealment suggests a very practical means to capture them, which 

 was tried here at the college the past season with perfect success. 

 It is similar to the Ransom process for capturing the plum cur- 

 culio, and consists simply in placing small pieces, boards, chips,
