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 Vesf>a 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 Dorcaschema wildii Uh. and 

 Dorcaschema alternatum Say, showing their destructive work on 

 osage orange; also Goes pulverulenta 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- 

 terus scabncollis, Xyleborns ccelatus, Tomicus cacographus, Den- 

 droctonus rufipennis, Crypturgus atoinus 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 family 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 new) and n remain doubtful. Of the 255 

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