Cerambycidae from Harrisburg, Pennsylvania, and 

 vicinity, with notes (Coleop.).* 



By W. S. FISHER and H. B. KIRK, Harrisburg, Pa. 



Having accumulated notes and data on collecting and rear- 

 ing longhorn beetles, we give the results, thinking they may be 

 of some interest to others. 



The region about Harrisburg is quite variable, affording a 

 great variety of food plants. Here and there are small groves 

 of dying hickory trees which are ideal for night collecting, 

 and on the mountain sides along the edge of woods are patches 

 of wild hydrangea, rose and Jersey tea. When these plants are 

 in bloom, they are visited by a number of species, especially 

 the tribe Lepturini, and on a warm day the blossoms are 

 swarming with insects feeding on the pollen. Near Harrisburg 

 a pipe line has been laid across the mountains and the trees 

 have been cut down for a number of feet on each side of this 

 line, leaving an open space through the dense woods. A great 

 many insects are attracted to this open space from the sur- 

 rounding woodlands and are found during the warm part of 

 the day swarming over the blossoms, or nesting on the upper 

 side of the leaves, apparently indulging in the luxury of a sun 

 bath. 



A great deal of our collecting was done in the usual way. by 

 sweeping flowers and beating dead branches, but the most in- 

 teresting was the collecting at night with an acetylene light. 

 A number of the species that are seldom taken during the day 

 time, and which seem apparently rare, were secured in numbers 

 by this method of collecting. Some of the species were found 

 running up and down the tree trunks, while others were ovi- 

 positing in the dying trees. When the light was thrown on 

 the tree trunks, the insects on them would remain motionless 

 until the light was removed, when a slight touch would cause 

 them to fall into the cyanide bottle. 



During the early months when the ground was still frozen
