and will be remedied. The situation is relieved somewhat by the thought 

 that there is certainly one unique collection of the ^gerians in this 

 country, namely, that of the late Henry Edwards. What disposition is to 

 be made of it I know not. Perhaps no one does. All sincerely hope 

 that it may speedily find a safe resting-place, accessible to the interested 

 student, and where it will be properly cared for, and will duly honour our 

 foremost student of this group. 



The list of species of this family thus far collected at Columbus, I am 

 aware, is only a partial one — one which it is hoped may be greatly 

 increased in the near future. Such facts as are at hand, it is hoped, will 

 prove interesting and suggestive. I follow the generic arrangement of 

 Henry Edwards in Grote's Check List of N. A. Lepidoptera. 



Melittia ceto. West., (cucurbitce, Harris). — The squash-borer occurs 

 abundantly in Central Ohio, and, indeed, throughout the State. In 

 localities where cucurbitaceous plants are cultivated on a commercial scale 

 it is a veritable pest. Is it double brooded ? Since Dr. Harris's account of 

 its habits more than sixty years ago, it has been regarded as single 

 brooded, the moth, appearing in early summer, the mature larva enter- 

 ing the soil in July and August, enclosing itself in a gummy cocoon in 

 which it remains until the following spring, when it completes its trans- 

 formations. During the last days of August Prof F. M. Webster and' 

 myself found in squash vines on the Ohio Agricultural Experiment Station 

 Farm larvae of different sizes ; a few inches below the surface cocoons 

 containing larvae were found, and one fresh imago was taken resting on 

 the leaves. By September 20 all the larvae were out of the stems and could 

 be found in their dark, oblong cocoons from two to four inches beneath the 

 surface. My friend Webster asked me if the species was two-brooded. I 

 replied by asking him the same question. At the time I did not recall 

 the paper by Prof. S. H. Scudder in Psyche, vol. iv., p. 303, in which he 

 recounts finding in squash vines on Cape Cod in September two larvae, 

 one much larger than the other and apparently specifically distinct. He 

 describes each and raises the question, Is Af. ceto double brooded or are 

 there two species passing under that name ? Only the larger forms found 

 by the writer were preserved and carefully examined ; they were typical 

 Melittia ceto. The single imago was likewise a typical example of that 

 species. It seems probable from the facts at hand that in Central Ohio 

 and South the species is double brooded.
