Order HYMENOPTERA. 



Ill this order the adults have four wings with comparatively few veins and 

 cells, never netted, the secondaries usually smaller than the primaries, the two 

 pairs hooked together in flight, naked, not clothed with scales and usually 

 transparent. The mouth parts are mandibulate, the tongue often developed 

 into a long lapping organ, the ovipositor developed into a sting, an augur, a 

 saw or a drill, according to the habits of the insect. Metamorphosis com- 

 plete. 



This order contains the bees, wasps, ants, sawflies, ichneumon flies and the 

 like ; a mixture of injurious and beneficial species, with the latter decidedly in 

 the majority. Our collections in this order are only fair and have been chiefly 

 made in South Jersey where Mr. William Fox, of the Academy of Natural 

 Sciences, Philadelphia, has collected rather thoroughly. A number of other 

 Philadelphia collectors have made frequent trips into New Jersey so that we 

 have a fair knowledge of the fauna south of Camden County. Mr. William T. 

 Davis has collected many species on Staten Island, Mr. M. S. Crane has taken 

 a number at Caldwell, and I have picked up a few almost everywhere, and this 

 gives us our knowledge of what occurs in the eastern, central and northern part 

 of the State. 



The list as it stands, aside from the economic notes, definitions and comments, 

 is the work of Mr. William H. Ashmead, Assistant Curator of Insects in the 

 United States National Museum. All the divisions are in accord with his own 

 classification and the numbering of the families and sub-families accords with 

 that of the complete arrangement. It will indicate by the breaks the number 

 of those not represented in the State. 



In this list all the records and all notes not otherwise credited are my own. 

 No attempt has been made to define some of the families because based upon 

 characters recognizable only by the specialist. 



Sub-order I HETEROPHAGA. 



Super-family I APOIDEA. 



This contains all the bees, social and solitary, and the insects are usually 

 more or less hairy, the hair plumose, feathered, twisted or branched, sometimes 

 dense, sometimes very sparse, sometimes evenly distributed, sometimes massed 

 at one point. The tongue may be long or. short, and may be either straight or 

 folded when at rest. The hind legs are often modified in the females and 

 workers to serve for carrying pollen, and sometimes the under side of the breast 

 or of the abdomen serves the same purpose.
