Notes on some Coleoptera. 



By M. L. Linell. 

 I have been led by my observations to believe that some Carabidw 

 do not hibernate in the imago slate. I have never been able to find Nebria 

 pallipes in early Spring, but on May 30th for a number of successive years 

 I have found numbers of specimens, but all immature. In the month oi 

 June it becomes common. 



I have also become convinced that Silvanus planaius is the feiTiale of 

 6". bidentaius. I have taken the two together in numbers, and found one 

 pan- in copula, so that the evidence of their identity is at least very strong.

Last year, while collecting on Staten Island, I found on a tree stump 

 a specimiCn of Tomoxia bideniata. Waiting about the place for some two 

 hours, I succeeded in taking 16 specimens, all having alighted on the 

 same stump. 



This Summer I went for the purpose of getting the insect, to the 

 same place, but a little earlier in the season. I found Tojuoxiw sitting 

 on the same tree stump, but in every case they were T. lineella. They 

 were very shy, and as I did not have my net with me, I was able to secure 

 only one specimen. The same day I saw three specimens of T. lineella 

 in my umbrella all flying away. But there was no sign anywhere of T. 

 bidentata. I am quite of the opinion that T. lineella is the male of T. 

 bideniata, and I am the more strongly inclined to this opinion, as it agrees 

 with the general tendency of the family to greater development in the male 

 of the maxillary palpi.
