colored pencils, and as Hai-ris himself allows 

 does not agree with Abbott's figure of tlic larva 

 of iesselkiriSj although, as he very candidly re- 

 marks, " the moth is the same"' (p. i'91). To 

 the moth produced from the larva with orange- 

 colored pencils that feeds exclusively on the 

 buttonwood or sycamore, whereas the other one 

 feeds on a great variety of different trees, the 

 name of i7"«»'ma'lias been given by the Senior 

 Editor. "Singiilav to relate, different as the larva; 

 are, and different as are their foodplaiits, the 

 moths arc absolutely undistinguishablc. 



P. 298. Two very distinct larvx are here de- 

 scribed wnAcv Dryocampa pellucida. The first 

 is probably that of Dr. rubicunda, which feeds 

 on maple. The second is the same as that de- 

 scribed under the name of Dr. bicolori in Proc. 

 Ent. Soc. Fhila., III. pp. 425-G, and mayor may 

 net be the true^jeZ/!(Ci'fZ«. 



P. 299. Olketicus coniferarum, Ilarr. MS. 

 (Plate III. Fig. 4) is Thyridopteryx ephemerw- 

 formis, Haw. See p. 122 and pp. 242-4. 



P. 307 . Astasia = Parathyris ^ Apatelodes 

 Packard. 



We notice one error of the press which it may 

 be as well to correct here. On p. 224 " the 

 cabinet of Sir Jos. Blake " should be " the 

 cabinet of Sir Jos. Banks," as is manifest at 

 once from tlie last paragraph but one on page 

 1C4. 



The Butterflies op Noutii America, with 

 colored drawings and descriptions, by Wm. TI. 

 Edwards, published by the American Entomo- 

 logical Society of Philadelphia. Part 3 ; price 

 $2 50. AVe have on previous occasions out- 

 lined the design of the author, to issue this 

 beautiful work in numbers at intervals of three 

 mouths. With Part 3, now before us, is com- 

 menced a synopsis of North American spe- 

 cies to be completed with the volume. This 

 part also contains descriptions of and notes on 

 Argynnis monticola, A. Halcyone, Limenitis 

 Proserpina, Lycmna violacea, L. Lygdamus, 

 Thecla Iwta, and T. acadica. The colored 

 plates illustrating these species are unsurpassed 

 in splendor, naturalness of color and correct- 

 ness of detail, while the typography and press- 

 work are such that Americans may feel 

 Justly proud of the work. Orders should be 

 addressed to E. T. Cressou, 518 South Thirteenth 

 street, Philadelphia, Pa. 



Popular American Entomology; being a 

 Guide to the Study of Insects, by A. S. Pack- 

 ard, Jr., M.D., Salem, Mass. Parts IV, V, and 

 VI of this valuable work have been duly re- 

 ceived. Part IV concludes the Ilymenoptera. 

 Beginning the account of the Lepidoptera, it 



describes the more common Butterflies, giving 

 in full the transformations of several species. 

 Part V continues the Lepidoptera and contains 

 two full-page illustrations on wood. Part VI 

 concludes the Lepidoptera and commences the 

 Diptera, and contains a beautiful steel plate 

 illustrating the transformations of many of our 

 moths. The press work is fully equal to that 

 of the preceding Parts, and the work, when 

 completed, will prove a valuable addition to 

 American Entomological literature. Subscrip- 

 tions received by the author. Each part 50c. 



ANSWERS TO CORRESPONDEXTS, 



Cannibal Mites— f. S. Dark, Decatur, ms.—Tho 

 elongate-oval eggs foiuid under tlie surface of tlio 

 earth are those of some large (irasshopper — perhaps the 

 Carolina Grasshopper ((Effipoda Carolina), a large spe- 

 cies with the hind wings hliulc with a cream colored 

 border. The velvety scarlf t niitrs about one-eighth of 

 an inch long, which you found proving on these eggs, 

 are a species of TroiidihVmm. either identical with or \ 

 very closely allied to the T. aerkeum of Sav. This 

 liabit of theirs, so far as we aware, is a new fact, and a 

 very interesting one withal. The allied genus (Ery- 

 tkraus), to which the so-called "Red Spider" of tlie I 

 gardeners and greenhouse men belongs, is not a canni- 

 bal, but a plant feeding groui). 



Gnats — W. 0. HisVey, Minneapolis, Minn. — The 

 specimen sent is, as you supposed, not a Mosquito 

 (i'ulcr) but a Gnat (Chironomus) . The latter may be 

 readily distinguished from the former bv liaving no 

 elongate beak adapted for suiH<iiig blodil. In both 

 genera the males have wi<lely tcatlu-icd antcniuc, and 

 the larva; of both reside in the water. Certain species 

 lielonging to the latter group occur in the spring of the 

 year in enormous numbers in the neighborhood of large 

 l^odies of water; sometimes gathering in the air in such 

 enormous clouds that they have been mistaken at a dis- 

 tance for smoke issuing out of buildings or hay-stacks 

 supposed to be on Are. 



Cut-worms severing- Cabbag:e Plants— J'. C. 



Bnrch. Jejferson City, Mo. — The dark greasv-looking cut- 

 worms with a dull llesh-colored back, wliich have sev- 

 ered so many of your cabbage plants— some just above 

 and others just below the surface of the -I'ouiid— are 

 the larvae of the Lance llustic (.(<;/■.,//,» ),i;fn;i. Harris). 

 This worm has been called the'(irca-^v ciit-Wdrm by 

 the Junior Editor, and an account of it with its trans- 

 formations may be found in his "First Annual Report," 

 pp. 80 — 81, accompanied with figures of the moth. 



Beetle named — /. M. Siiaffer, Fairfield, Iowa. — 

 The beetles which you send and whicli were flying 

 about in great numbers on the 4th of May, are the 



Anisodacti/lus baltinwriensis , Say. 



Xlger Beetles-/. M. Shaffer, Fairfield, Iowa.— 

 The second lot of beetles which you send, and which 

 you found "flying and lighting on the low dry soil in a 

 ravine, through which a small creek passed, and which 

 was much frccjuented by cows , ' ' are the common Tiger 

 Kci'tle, Cicindela vulgaris. Say. 



Gigrantic IVater Bug—/). A. A. Nichols, West- 

 fieh!, N. Y. — The large brown flattened insect which 

 you "found crawUng on the ground near the horse- 

 barn," is the Crigantic Belostoma (Iklosloma i/raiulis, 

 Linn.) spoken of on page 11!> in answer to S. iJ. Mun- 

 ford of I'rinceton, Ind. 



Hole Crickets — Thomas W. Gordon, Georgetoion, 

 Ohio. — The Mole Cricket which you send is one of our 

 most common American species- the Gryllotalpa horealis 

 of Burmeister. Mr. S. H. Scudder in his late Revision 

 of these insects describes three N. A. species of whicli 

 G. lorealis has the most extended range.
