that they hibernate during the winter in the perfect state, and lay 

 their eggs in early summer. This is true of the allied Proconia 

 costalis, and Heliochara communis^ which I have often found fully 

 developed in early spring, just emerging from their winter quarters. 

 The eggs are very large as compared with the size of the insect, and 

 as but very few are laid, these pests are never liable to become 

 excessivel}' abundant. This insect remains in the frothy secretion 

 during the early stages (nymph) , but, after reaching the adult stage, 

 does not make this secretion, and becomes very active. Although 

 the wings are well developed it does not fly any great distance, but 

 makes long leaps, and runs quickly, often with a peculiar sideways 

 motion to the opposite side of the plant from the observer. 



The Spume Spittle-insect, (Philaerms spumarius Linn.) is very 

 variable in color, about one-fourth of an inch in length, of a clay- 

 yellow color, and sprinkled more or less with brown, but some varie- 

 ties are almost entirely brown. The female of this species lays from 

 eight to ten long whitish eggs. 



The Liued Spittle-insect, (Philaenus Imeatus Linn.) is about one- 

 fourth of an inch long, of an ochre yellow color, with a whitish stripe 

 on the costa or outer edge of the wing covers, and a brownish stripe 

 within and parallel to it. Some of the varieties are dark brown with 

 a whitish costal stripe. 



Although the mass of froth on the stems of grass is quite large it 

 usually contains but a single insect which is so small, that it can 

 injure the plant but very little, and it is very seldom that the pest is 

 abundant enough to make any material difference in the hay crop. 



Besides the above named species of Spittle-insects in Massachu- 

 setts, we have Clastoptera proteus, a common species on cranberry 

 and blueberry bushes, Clastoptera obtusa, on the leaves and twigs of 

 alder, Apliropliora parallela, on the twigs, and smaller branches of 

 pine, A. quadrinota, and A. signoreti on the grape vine, and A. 

 quadrangular is, on grasses, weeds and blackberry twigs. 



THE SQUASH BUG. 

 Anasa tristis (De Geer). 



About the last of June or the first of July, when a few young 

 leaves of the squash have started, the bugs come out of their hiding- 

 places, in crevices of walls or fences, where they have passed the 

 winter. The insects pair and the females lay their eggs in little
