bodies. The professor in concluding stated that in his opinion 

 he believes it to be purely a mechanical act. 



Mr. Fox exhibited a specimen of Vespa crabro, an introduced 

 European species, taken at Anglesea, N. J., by Mr. John Stur- 

 mer; the speaker stated that while it is quite common in the 

 northern part of New Jersey it is quite rare in this locality, this 

 being the second specimen the speaker has seen from so far south. 



Mr. Laurent exhibited a collection of Lepidoptera taken by 

 Mr. Wenzel at North Mountain, Pa., also Coleoptera and Le- 

 pidoptera taken at King and Bartlett Lake, Me., by Dr. Hughes. 

 He also exhibited photographs of Dorcasche7na wildii Uh. and 

 Dorcaschema alternatiim Say, showing their destructive work on 

 osage orange; also Goes pulveriilenta on the beech, and Cryp- 

 torhynchus lapathi on the willow. 



Dr. Skinner exhibited specimens of Mermiria bivittata found 

 at Cape May, N. J. They wonderfully mimic their surroundings, 

 and to such an extent as to make it almost impossible to see them 

 when they drop in the herbage. 



Mr. H. W. Wenzel read the following list of Scolytidae taken 

 at North Mountain, Pa., by Mr. Johnson and himself Xylo- 

 ter-us scabricollis, Xyleborus ccslatiis, Tomicus cacographus, Den- 

 drodonus rufipen^iis, Crypturgiis atotmis and two unknown spe- 

 cies. The first species was found boring into hemlock and the 

 last six in spruce. 



Mr. Johnson spoke of the recent work of Mr. D. W. Coquil- 

 lett, "Revision of the Tachinidae of North America." This 

 valuable publication being the first systematic work on this diffi- 

 cult fimily in this country. Some idea of the fireat reduction of 

 generic and specific names may be derived from the following 

 figures: about 575 species are recorded, of which 318 are recog- 

 nized (92 being newj and 11 remain doubtful. Of the 255 

 genera recorded, 125 are recognized (12 being new).
