thrown off, and destroys the bud. Does it not belong to the Elater 

 family? It seems to have two broods, one now, and the other in (ulv. 

 Or do they change from the small cocoon around the buds to the partlv 

 grown leaves, and form another cocoon ? Or does the latter belong to a 

 later brood ? In the fall, the undersides of the leaves of some trees 

 are fairly covered with their houses, but then I can kill them by spray- 

 ing, as they feed on the leaves. What I want, is to get at them in the 

 spring. Can it be done ? The second white worm, with a dark head, 

 works into the new growing shoots, and will destroy the fruit if it gets 

 too plentiful. How can I get at it, as it is working inside the young 

 shoots going down ? Can you give me the history of both, as they 

 develop into a serious pest ? " 



Answer by M. V. Slingerland : " The material sent by C. E 

 P. consisted of several opening pecan buds webbed together ; two 

 kinds of small caterpillars, one light green in color with black head 

 and neck, the other dark brown, with similar Mark head and neck; 

 and several pupae inclosed in cocoons made by webbing the leaves 

 together, as shown at a in Fig. 133. Judging from the appearance of 

 the buds sent, the insects were doing very serious injury. The mate- 

 rial was placed in some of my breeding cages at the insectary, and in 

 a few days, there emerged from the pupae some pretty little gray moths 

 with blackish markings; two of them are shown natural size at b in 

 Fig. 133. As we had nothing like them in our university collection 

 here, one was sent to an expert for its name. His reply was that he had 

 labeled the same insect in his collection, Steganoptycha bollina. His 

 specimen came to him from Texas several years ago, but the name has 

 never before been published ; so C. E. P.'s pecan bud worm proves to 

 be new to science. The moth is, probably, the parent of the green 

 worm. 



" I failed to breed the brown caterpillar which seems to work very 

 similarly to the bud moth of our New York apple orchards, 

 early appearance of the moths. April iS. would indicate a second 

 brood of the worms during the summer. Neither of the worms 

 which I found in the material sent, has anything to do with the ela- 

 ters or snapping-beetles ; all were the caterpillars of small moths. 



" Information about this new insect is so scanty that no definite ad- 

 vice can now be given as to the best time and manner to fight it. C 

 F. P. thinks that he can control it later in the season, and if this be 

 true, it ought very materially to lessen the numbers to appeal on the
