THE AMERICAN ENTOMOLOGIST.

We found no larva; but found several In the pupa state . 

 Also in each chamber we found the remains of one of 

 our common summer locusts (cicada) . Tills locust is 

 considerably larger than the 17-year species . The bur- 

 rows were just large enough to admit it. One person 

 witnessed the operation of taking in a locust. The 

 wasp had it on the top of a fence; he flew off with it 

 but came to the ground before reaching the burrow ; 

 then by means of a hook on each of his hind feet, he 

 dragged it in on its back . We captured a few of the 

 wasps. I endeavored to get its name. A friend fur- 

 nished the following: Locust Stinger — Slizus grandis, 

 of Say; communicated to Wra. J. Buck, March 5th, 

 1861, by Isaac Lea, President of the Academy of 

 Natiu'al Sciences, Philadelphia. 



We reserve our own opinion till our next 

 number, in which we contemplate publishing a 

 thorough article on tlie 17-year cicada. If any 

 of our readers in the diflerent parts of tlie coun- 

 try have reliable dates of its appearance in their 

 section, we shall be glad to receive them. 



OUR CLUB RATES. 



To all persons interesting themselves in the 

 American Entomologist we will allow twenty- 

 five cents on every dollar, on all over five names 

 which they send. This can either be retained 

 as a cash premium, when the names are sent, or 

 its equivalent be had in horticultural books at 

 publishers^ rates. , 



To those Horticultural and Agricultural 

 journals that will offer the Entomologist in club 

 with theirs, our price is seventy-five cents per 

 copy. 



We have already made arrangements to club 

 the Entomologist with the following periodi- 

 cals, for the prices mentioned:

^° We heartily tender our thanks to the sub- 

 scribers to the old Practical Entomologist for 

 the manner in which they are sending in their 

 subscriptions, and for their kind words of en- 

 couragement. Also to the Agricultural and 

 Horticultural press for the many commenda- 

 tory notices they have given us. We hope that 

 our exchanges will call the attention of their 

 readers to this second number, as a proof of our 

 intention to improve with age. 



ON OUR TAULE. 



The publishers, D. Appleton & Co., of New 

 York, liave sent us " The Insect World," from 

 the French of Louis Figuicr, author of "The 

 World before the Deluge," " Tlie Vegetable 

 World," "The Ocean World," etc., etc., being 

 a popular account of insect life, illustrated by 

 664 wood cuts. Although this work will not 

 bear very strict criticism in a scientific sense, it 

 is exactly what it claims to be, namely, a popu- 

 lar work. It will be found most interesting to 

 the general reader, and should have a place in 

 every good library. The engravings, tliough of 

 a high order, are not so perfect as those in 

 •' The Vegetable World." 



ANSWERS TO CORRESPONDENTS. 



Squa.sb-bug; its Ckang-e of Color. — ./ Pef/am, 

 Uhampaign, Ills.^—T\\ii bugs you send for dcteriiiinatioii, 

 and which you found on tliuSiiuash vines, arc tlir larval 

 and pupal states of the coiiiiiniii Siiua.-ilj-hui; ( (,,««« 

 triatis, DeGeer). The true buys (Uemii'TKR.\) though 

 they undergo but slight changes in form from the time 

 of leaving the egg till they are full grown, yet generally 

 underj^o great changes in color. The Squash-bug is no 

 exception to the ride, and the colors of the young difter 

 so much from those of the full grown bug. that the 

 former have often been sent to us for detcnnination by 

 parties who were well acquainted with the sober brown 

 appearance of the latter. Our readers will therefore 

 bear in mind that the young bugs, when tii-sttliey hatch 

 from the eggs, have the body green., with the head, 

 thorax, legs and antenna: of a delicate pinh color. In 

 about two days from the time of hatching, and before 

 the 1st moult, thejiinh parts become hlach, and the green 

 body ash-gray. These colors are retained through the 

 2d moult, the head and thorax becoming somewhat 

 lighter. After the 3d moult, or while the insect is in 

 the pupa state, the wing-sheaths, which have become 

 considerably developed, together with the head and 

 thorax, are blmsA-gray , and the body of a lighter yel- 

 lomsh-gray, while the legs and antenna have a tinge of 

 brown. After a 4th moult it acquires its wings and its 

 characteristic size .and color. Throughout its growth 

 this bug is finely speckled with black, the speckled ap- 

 pearance becoming the more obvious as it matures. 



'White Crub; immunity from it next year 

 in Clinton County, mo,— John P. McCartneu, 



Garmron., Mo. — You wish to know if the white grubs 

 will remain in the ground next year, in your section of 

 the country ; and fear that , if they do , there will be little 

 use in trying to raise a crop of any kind, as they have 

 already ruined a great deal of meadow. From the fact 

 that the beetles swarmed there diiring the last of May, 

 18fiG, making a noise on the trees "like the coming up 

 of a storm of wind andrjiin;" from the grubs having 

 been small and not having done much damage in 1867, 

 and from the fact that they are now " fuU-giown , line 

 fat fellows," we can confidently assure you that the 

 grubs will not trouble you next year. In accordance 

 with their natural habit, they will transfoiin to pupie 

 late this fall, or early-next spring, and issue in May as 

 beetles, as they did in 1866 ; and the grubs will not be 

 really troublesome again till the summer of 1871. 



Insect Enemies of tite Colorado Potato 

 Beetle — Dr. S. H. Kriedelhaugh , Clai-imia, Page Co., 

 /owa.— The three insects which you send, and which 

 have saved your potatoes the present season, by prey- 

 ing unmercifully on the larva; of the Colorado beetle, 

 a.re (1) Anna «pmo«ffl,1)allas; (2) Peduvius raptaim-iu« , ^ 

 .Say; (S) Hippodamia cormergens, Guerin. As we shall 

 figure these three in our next issue we will not speak 

 further of them at present. You have our sincere 

 thanks for the interest you manifest in our undertaking 

 and for the good words in the "National Platform.''
