Doings of Societies. 



At the January 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 address, 

 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 Lahaway, N. J., and stated that he had found there 

 five species of Scolytidse in decaying pine trees, including a 

 new species of Dendrocfonus. 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 Dendrodonus were shown. Tomicus caligraphtis makes 

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

 any species of Toinicus. Totnieus cacographiis lives much higher 

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

 thicker bark. Cryphirgus ahdaceiis makes small galleries, ir- 

 regular in form and close together. A species of Scolytus 

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

 very short burrows. G?iathotrichus materiarhis differs in habits 

 from the others mentioned by penetrating into the solid wood, 

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

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

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

 containing a Monohammus lar\^a was shown and its mode of 

 entry and exit described. Some twigs of hickorj' girdled by 

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

 had been found, which raised the question whether the girdling 

 w^as always done for oviposition. 



Mr. Daecke said he had frequently observed I'^espa crahro 

 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 

 Scolytidae on the spruce at North Mountain, Pennsj'lvania. 

 Dendrodonus riifipennis had made burrows, but no live speci- 

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