thing to say of the destructive habits of the hirviie of these species, this, 

 seems to be the ajDpropriate place to i^resent 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 number 

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

 throwing light upon this question; his quotation from the manuscript 

 drawings by Abbot clearly prove that iu Georgia it has two annual 

 broods. He also cites the facts of his own observation 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 iu its life-history not yet explained. 



Larvie put into breeding cages in Sei)tember last gave imagos in 

 May and June. Larv« were found destroying the squash plants early 

 in July; by the 15th to 20th I transferred the plants to breeding cages 

 with larva? of different sizes. These shall be carefully watched and the 

 result reported.* 



Sciaptenm tricincta Harris. — This species was reared by me several 

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

 stems of Populus candicans and Salix caused by the larva" of iSapcrda 

 mcesta and Saperda concolor. The i^resent season I have found it at Col- 

 umbus, with similar habits, in the stems of the willow injured and en- 

 larged by the larva of *S'. concolor. The beetles appeared from the mid- 

 dle of May to the middle of June; the female gnaws deeply through 

 the bark into the wood, generally near a branch, and places an egg at 

 the bottom of each pit; the larva is soon burrowing under the bark and 

 into the wood ; there are often several at the same point. The JEge,- 

 rians appear later, in June and July, and place their eggs in the excres- 

 ceuces caused by the boring young of the beetle. I have not yet found 

 instances in which it was clearly apparent that the young Sciapteron 



*NoTE. August 8. — By August 1 a few larvtB 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 <le8cril)ed by 

 Prof. Scudder in Pui/vhe, vol. iv, p. 303. Some of these were isolated, and after a 

 few days they molted, giving the typical form. This seems to prove that there is- 

 but one species. 



It may be interesting to note that these larvae will feed in the stems and roots of 

 Eclihiocysfis lohata; also in the fruit of the Muskmelon. I have not watched them 

 to maturity in either. 



Auijust 27. — On returning home, August 25, I found that three imagos had emerged 

 in the vivaria from larvte transferred from the field between .July 15 and August 1^ 

 \ny son had noted the dates of appearance as follows : One each on the 20th, 21st, 

 and 23d; since then two more have come out, and seven fresh imagos have been 

 captured in the field. These facts I consider sufficient to prove that in central Ohio 

 there may be a second brood.
