Doings of Societies. 



At the Januar}- meeting of the Feldman Collecting Social, 

 held at the residence of Mr. H. W. Wenzel, 1523 S. Thirteenth 

 Street, twelve members were present. 



This being the annual meeting the President read his addivs>, 

 reviewing the progress of the Society, and speaking of the ad- 

 vances made in the methods of collecting insects. 



Prof. J. B. Smith referred to a former communication on a 

 trip to L,ahaway, N. J., and stated that he had found there 

 five species of Scolytidae in decaying pine trees, including a 

 new species of Dendroctonus. Trees attacked by this insect 

 may be recognized by large adherent clumps of pitch, in the 

 center of which the insects live. All stages of the insect had 

 been found. Specimens of pine park illustrating the burrowing 

 of the Dendroctonus were shown. 'fomicits caligraphits makes 

 galleries extending in all directions, and are the largest made by 

 any species of Tom/cut. Tomicus cacographus lives much higher 

 in the trees than the two preceding species which dwell in the 

 thicker bark. Crypturgus alntaccus makes small galleries, ir- 

 regular in form and close together. A species of Scolytits 

 occurred in the trees, but no specimens were found. It makes 

 very short burrows. Gnathotrichus watcriarius differs in habits 

 from the others mentioned by penetrating into the solid wood, 

 the galleries being quite long, and makes small larval burrows. 

 Other insects, such as feed on Scolytidse or had entered the 

 burrows for other purposes, had been found. A piece of wood 

 containing a Monohammus larva was shown and its mode of 

 entry and exit described. Some twigs of hickory girdled by 

 Oncidcres were exhibited. In 30 or 40 twigs not a single larva 

 had been found, which raised the question whether the girdling 

 was always done for oviposition. 



Mr. Daecke said he had frequently observed / 'cspa crabro 

 gnawing at twigs, and suggested this wasp may be responsible 

 for some of the girdling. 



Mr. Johnson stated that he had found several species of 

 Scolytidse on the spruce at North Mountain, Pennsylvania. 

 Dendroctonus rufipennis had made burrows, but no live speci- 

 mens had been found and its work was confined to the base
