ECOLOGICAL NOTES ON INSECTS 



By Chas. Dury 



During forty years colkcting insects near Cincinnati, Ohio, 

 some interesting facts in geographical distribution have been 

 met with. Species belonging to the fauna of the South have 

 been taken, mingling with those regarded as northern in their 

 range. One that has escaped capture in all these years is 

 Nanosella fungi, a beetle belonging to the Trichoptcrygidce. 

 Described in 1868 from Mobile, Alabama, it has remained very 

 rare. It is perhaps the most minute beetle known, being less 

 than 1-3 mm. in length. July 18 to 23, 1907, I took seventy- 

 five on a small patch of Polyponis fungus, that was growing 

 on a beech log".

MORIO MONILICORNIS, Lat. 



Seven specimens of this graceful Carabid beetle were taken 

 April 19, 1908. They live under the bark of dead trees. They 

 are abundant in Florida and Lower California. I was sur- 

 prised to find them so far north. 



LoxANDRus RECTUS, Say. 



Thirty-six specimens of a Loxandrus that comes nearest 

 rectus were taken in a damp, shady ravine or creek bed. They 

 were hiding under flat stones. May 19 to August 21, 1909, 

 they were very abundant. I have always found Loxandrus 

 rare before. This is an illustration of the fact that the so- 

 called rare species may be common enough if one can only 

 find their habitat at the proper time. 



Pentagonica flavipes, Lee. 



This pretty little Carabid was taken abundantly November 

 3 to 10, 1909, in company with a few Cyparium Havipes, Lee. 

 Pentagonica has never been taken here before, and but one of 

 Cyparium. They were sifted from the debris under fungus.
