Reinarks. — This species is probably more widespread than indicated 

 by present records. According to Mr. Busck the adults fly in the early 

 morning hours after midnight and are, therefore, collected infre- 

 quently. Mr. Busck also states that the larva probably will be found 

 in rotten wood.
