96 ABSTRACT OF COMMUNICATIONS. 
Gibside, in the County of Durham. It is a bolder insect than 
many of its congeners, suffering a near approach before it rises, 
and soon returns to the place from whence it had been disturbed. 
This species also, instead of retiring along with the sun, remains 
abroad till sometime after sunset. This habit Mr. Hardy also 
also observed in Pachyta octo-maculata. Mr. H. verified the 
observations of St. Fargeau on some of the habits of the Zen- 
thredinide, having caught several species preying on other in- 
sects. After several observations on the abundance or scarcity 
of insects generally, this season, he concluded by noticing the 
capture of two specimens of Bombus Skrimshirianus, which is 
accounted one of our rarer large bees, but Mr. H. mentioned that 
he had frepuently met both with it and its nest in Berwickshire. 
At the September meeting, Mr. Hardy read some notes on 
the habits of the Horse Leech (Hamopsis sanguisuga ), in which 
he stated, that he had verified by observation, what had been 
formerly stated respecting this animal, that the common earth- 
worm appeared to be its ordinary food. Mr. H. also mentioned 
some species of plants in which he had observed monstrosities 
more than usually remarkable. Of Dactylis glomerata, he ex- 
hibited and described very extraordinary viviparous heads.
