wings are the first two pairs of legs and the antenna. The 

 mesothorax and metathorax are easily recognized by their attach- 

 ment to the wings. The prothorax lies 

 immediately in front of them, and the 

 remainder of the front of the body belongs 

 to the head. In many species this is 

 divided, by transverse sutures, into two or 

 three sclerites. The mouth is surrounded 

 by the lab rum in front and the tongue be- 

 hind. On the sides the mandibles are lo- 

 cated when they are developed, but they 

 are absent in most species. In the more 

 primitive forms the maxillary palpi (or 

 "eye-collar") appear immediately behind 

 the eyes as small oblong or triangular 

 sclerites. The abdomen is composed 1 of a 

 regular series of segments, the first three 

 or four of which are, in most cases, immov- 

 ably soldered together. Then there come 

 one or more movable incisures, and the ter- 

 minal segments are again fused. An in- 

 complete pupa is one in which there are 

 four or more movable incisures, one more 

 in the male than in the female, and in 

 which the body is provided with spines to 

 enable the pupa to work out of its burrow 

 or cocoon or out of the soil. In an obtect 

 pupa there are three or less movable in-
