rapidly and takes flight, and unless the collector be looking 

 particularly for it, its chances of escape are good. My cap- 

 tures heretofore have been one every few years. 



Five examples of Melasis pecti7iicornis Mels. occurred at Mar- 

 ion, Mass. , on a dead branch of tupelo. I took them at three 

 different times during a period of two weeks, from July 7th to 

 25th, and always on the same branch. Each time I captured 

 them I went carefully over every other tupelo in the neighbor- 

 hood, but failed to strike any other specimen on any other tree. 



Perigora atriceps Lee. occurred sparingly at Marion during 

 the latter part of July and first half of August — some ten or 

 twelve examples being beaten from thick matted grapevine and 

 brush. Microscopha clavicor7iis Lee. was also taken at the same 

 time rather plentifully. 



To Mr. Blanchard belongs the credit of separating from some 

 ^^a^2 captured by us (Messrs. Blanchard, Fall and Bowditch), 

 the rare Agabus plajiatus Sharp. It occurred in company with 

 Agabus gagates in the debris in the bed of a small brook at 

 Marion, in August. Later, in September, I took a few more 

 of both sexes. It is easily distinguished from its allies by its 

 thickened thoracic margin. 



It was a good season at Marion for Stylopized wasps, and one 

 example observed had seven Xeiios peckii Kirby \n its abdomen. 

 I got five % ' s and a number of wasps with the 9 ' s protruding. 



Xylotrechus sagittatus Fab. was very plenty in Marion in 

 September ow freshly cut white pine. After the tree has been 

 down ten days or two weeks the beetle seems to almost leave it 

 for fresher material. With it occurred great numbers of M0710- 

 hammus confusor Kirby. Both these beetles were to be found 

 on the wood within a few hours after it was cut. 



For a day or two in July Harmoriia 12-maculata Gebl. with 

 1 4-guttata- senilis Rand, were rather common on white birch, 

 and I obtained a very good series of eighteen examples show- 

 ing variations of marking, etc. Heretofore my captures have 

 been one or two examples in a season. Also two examples 

 which are wholly rufous and which I unite with it with a ?. 

 These latter occurred on red cedar later in July. 



Tropistermus ^.-striatus Horn were very abundant in brackish 

 pools at the rear of the beach at Marion.
