was very common toward the end of the season; C. azurea was equally com- 

 mon throughout, and the same is true of C. harrisii. C. sex-signata was less 

 so, and a small form that may possibly be a much dwarfed jemorata was 

 scarce. It seems probable that all of these feed on peach, femorata unques- 

 tionably so, while azurea has been noted from March to July as being a com- 

 mon frequenter of peach trees, especially when old and diseased. About a 

 dozen other species of the family were taken. 



Lampyrid^^e, — Also a very common family, certam small species of Telephorus 

 being very abundant, arranged according to abundance. Chauliognathus was 

 also extremely common later in the season. 



Malachiid.-e.— Fairly common. 



Clerid.^. — Made fairly common by the presence of Clerus thoracicus in some 

 numbers. 



Ptinid.^. — Several species, the "twig borer" AmpMcems bicaudatus in some 

 numbers. 



SCARABJEID.E. — The presence of Anomala undulata in numbers gave this family 

 considerable prominence that it would not otherwise have possessed. Lacli- 

 nosterna was unexpectedly scarce, though in some variety: L. fristis was the 

 only common species. 



Cerambycid.i;.— Rivaled only by the Chrysomelidse for variety, though few spe- 

 cies were abundant. Elapliidion viUosuni was common through the season. 

 In all about 40 species were found, and of them a few of t.ie smaller ones were 

 common. 



Chrysomelidje. — Over 50 species in this family were determined, though maoy 

 of them were of but occasional occurrence. The flea-beetles were represented 

 by some very prettily colored forms. Perhaps the most interesting econom- 

 ically was Diabrotica 12-panctata. This was one of the most common of all 

 the beetles, and is quite injurious to the peach in early spring, eating out the 

 center of the blossoms and opening buds. The potato and sweet-potato beetles 

 found their way in considerable numbers to the slaughter. 



Bruchid.e. — Rare. 



Texebrionidje. — Abundant, represented by some of the more common wood- 

 eating forms. 



CiSTELiD.^. — Common. 



Lagriid.e. — Quite common. 



Melandryid.^.— Rare. 



Pythid^.— Rare. 



MoRDELLiD^. — Rare until nearly the end of the season. 



Anthicidje. — Species of Notoxus were fairly common, and later in the season these 

 insects are among the most commonly seen on the trees, crawling continnally 

 over the leaves for some obscure purpose. 



Meloid.^. — Rare. 



Oti(;Rhynchid^. — Rare, except for one species, Aramicjus fuUeri, which in some 

 lots of the catchings was A-ery common, but was far from being uniformly so 

 throughout the season. What its habits may be in this connection is a question. 



Curculionid.^.— Co)lofrac/ie?^^s nenuphar of course formed a large proportion of 

 the total number of insects caught, but a proportion that lessened as the season 

 advanced, varying from 94 per cent under certain conditions to as low as 56 

 per cent toward the end of the season. This is in part due, we think, to the 

 fact that much fewer curculio were caught and partly, also, to the increased 

 numbers and activity of other insects. In addition to nenuphar, the following 

 species of Conotrachelus were taken: C. anaglypticus was common, C. senicu- 

 his, scarce, and C. cribricollis, scarce. All these were noted as being more 

 common during the latter part of the season. Others of this family were con- 

 spicuously numerous, as Chalcoderniusceneus,Antho)wmusscufellafus. and spe- 

 cies of Cryptorhynchus and Baris.
