NOTES ON AEGERIAD.E OF CENTRAL OHIO— II. 



BY D. S. KELLICOTT, COLUMBUS, OHIO. 



The first collection of notes on the Aegeriadfe of Central Ohio was 

 published in the current volume of the Canadian Entomologist. Since 

 the former notes left my hands additional observations have been made, 

 and a few more species collected. Inasmuch as I shall have something 

 to say of the destructive habits of the larvse of these species, this seems 

 to be the appropriate place to present these notes. 



Melittia ceto, West. — Concerning this species, in view of the facts 

 cited, I said in the former paper, "It seems in view of the facts at hand 

 that in Central Ohio and South it is double brooded." In the May num- 

 ber of the Canadian Entomologist, Prof. J. B. Smith has an interesting 

 note throwing light upon this question. His quotation from the MS 

 drawings by Abbott clearly proves that in Georgia it has two annual broods 

 He also cites the facts of his own observations in New Jersey, and 

 expresses his disagreement with my inference for the latitude of Central 

 Ohio. He may be right ; I am simply waiting to see. I still think there 

 is something in its Hfe-history not yet explained. 



Larvie put into breeding cages in September last gave imagos in May 

 and June. Larvae were found destroying the squash plants early in July ; 

 by the 15th to 20th I transferred the plants to breeding cages, with larvae 

 of different sizes. These shall be carefully watched, and the result 

 reported.* 



Sciapteron tricincta, Harris. — This species was reared by me several 

 years since at Buffalo, N.Y., from enlargements of the branches and stems 

 of Fopuhis candicans and Salix caused by the larvae of Saperd% moesta 

 and Saperda concolor. The present season I have found it at Columbus, 

 with similar habits, in the stems of the willow injured and enlarged 



*NOTE, Aun. 8. — By August 1st a few larvre had left the stems and entered the 

 ground ; by the 8th, the day of last examination, many had done so. Small ones are 

 comparatively few. Among the smaller ones there was an abundance of that second 

 form described by Prof. Scudder, in Psyche, Vol IV., p. 303. Some of these were 

 isolated, and after a few days they moulted, giving the typical form. This seems to 

 prove that there is but one species. It may be interesting to note that these larvs; will 

 feed in the stems and roots of Echinocystis lobata ; also in the fruit of the musk melon. 

 I have not watched them to maturity in either. 



Note 2, August 26. — On my return to Columbus, August 25, I found that three 

 examples of the imago had emerged in the vivarium from the larva; placed therein 

 between July 15 and August l. My son had noted the dates of appearance, as follows : 

 — One each on the 20th, 21st and 23rd ; to-day a fourth emerged, and three fresh ones 

 were captured in the field. These facts I consider sufficient to prove that in Central 

 Ohio there may be a second brood,
