SOME INSECT NOTES.* 

 By B. F. Webster. 



The little clover Halticus uhleri, has been studied and we have found that 

 there are probably not less than five annual generations at Wooster. This . 

 species has a peculiar interest, as there are two forms of females, one 

 having fully developed wings and the other has no wings at all, and 

 instead of flying or walking, as does the first, it hops about like some of 

 the flea beetles, and like them have the posterior femora enlarged. 



A peculiar case of retardation in development has come to notice dur- 

 ing the last year. On June 6, 1898, a number of saw-fly larvae, from a 

 strawberry patch near Wooster, were placed in a breeding cage in the 

 insectary. Others from the same source were added a few days after. 

 As nothing had emerged up to June 3, 1899, almost a year after, I in- 

 structed Mr. Mally to clear up the cage in which these larvae had been 

 placed with their food plants, but he was surprised to find the larvae stil) 

 alive in the small earthen cells into which they had retired for pupation. 

 The soil in the cage was carefully replaced, but still nothing developed. 

 September i6th, supposing all must have died, it was again decided to 

 clear up the cage, but we were again surprised to find the larvae alive and 

 in apparently good condition in their cells. The soil was again replaced 

 and we shall await the developments, as, up to date, over eighteen months 

 since the larvae ceased to feed, nothing has appeared. 



At the meeting of the Association of Economic Entomologists in Co- 

 lumbus last August, Dr. E. V. Kelt, State Entomologist of New York, 

 called attention to the occurrence of the 12-spotted asparagus beetle, 

 Crioceris jz-punclata at Buflalo, and in October, at the meeting of the 

 Entomolo,?icai Society of Ontario, Canada, Dr. Fletcher reported it in 

 eastern Ontario, opposite Buffalo, so that we may expect it to reach Ohio, 

 even as soon as next summer. This is an introduced species, coming to 

 us from Europe, but was first foimd here long after Crioceris asparagi 

 had begun to make its way westward. It may be stated that the latter 

 species reached Wooster for the first during the last year, and an ex- 

 tended seach about Sandusky revealed only a single individual, and this 

 at the Soldiers' and Sailors' Home just south of the city.
