We found no larvEe but found several in the pupa state . 

 Also in each chamber we found the remains of one of 

 our common summer locusts (cicada) . This 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— i'^i^Ks (/rant! is, 

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

 1861, by Isaac Lea, President of the Academy of 

 Natural Sciences, Philadelphia. 



We reserve our own opinion till our next 

 number, in which we contemplate publishing a 

 thorough article on the 17-year cicada. If any 

 of our readers in the different parts of the 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 tliat 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 TABLE. 



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

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

 the French of Louis Figuier, author of "The 

 World before the Deluge," " The "Vegetable 

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

 a popular account of insect life, illustrated by 

 564 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, though of 

 a liigh order, are not so perfect as those in 

 " The Vegetable World."

exception to the rule, aod the colors ot the youiig dill'cr 

 so much from those of the ftiU grown bug, that the 

 former have often been sent to us for determination 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 first they hatch 

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

 thorax, legs and antennte of a delicate pink color. In 

 about two days from the time of hatching, and before 

 the 1st moult, the »j«^- parts become Waci, and the green 

 hm\y ash-gray . Those colors are retained through the 

 •2d moult', the head and thorax becoming somewhat 

 lighter. After the od moult, or while the insect is in 

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

 cousideralily ilcvcloii.-,!, together with the head and 

 thorax, arc /./«;,/,-.,/./'/. and the body of a lighter yel- 

 lowish-gruii. while th.- hus and antennse have a tinge of 

 brown. Alter a 4th imiult 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.

 Iowa. — The three insects which you .send, and which 

 have saved your potatoes the present season, by prey- 

 ing unmercifully on the larviB of the Colorado beetle, 

 are (1) Arma spinosa, Dallas; (2) Reduvius raptatorius. 

 Say; (3) Hippodamia conrergens, 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
