FIFTH ANNUAL EFFORT 



egg-like object, without trace of articulation, and nearly as large as 

 the abdomen of the parent fly. Closely allied to these are the Bat- 

 ticks {NijGterihidce), whi^h possess neither wings nor balancers, and 

 remind one strongly of spiders. 



In this Order we may also place certain wingless lice (such as 

 Braula ccvca, Nitzsch — figured by Packard)*, which infests the Honey- 

 bee in Europe, but which has not yet been detected in this country. 



6 — OrTHOPTERA {opOoq, 



straight; Trrspa^ wings) or 

 Straight- winged Insects. 

 Characterized by having 

 the front wings (called 

 tegmina^ straight gindusu- 

 (edipoda differentiale. ally narrow, pergamene- 



ous or parchment-like, thickly veined and overlapping at tips when 

 closed: the hind wings large and folding longitudinally like a fan. 

 (Fig. 8.) Transformations incomplete. 



The insects of this Order have a lengthened body and very robust 

 jaws, with a correspondingly large head. The legs are strong, and 

 fashioned either for grasping, running, climbing, jumping or burrowing. 

 As in the other Orders where the transformations are incomplete, the 

 young differ little from the parent, except in the want of wings ; and 

 in many instances even this difference does not exist, as there are 

 numerous species which never acquire wings. There are no aquatic 

 OrtJioptera. Some are omnivorous, others carnivorous, but most of 

 them herbivorous. They form four distinct sections : 1st. Cursoria, 

 cockroaches; 2cl. Raptatoria, Mantes; 3d. Ambulatoria, Walking- 

 sticks; 4th. Saltatoria, Crickets, Grasshoppers and Locusts. 



T — NeUROPTERA (vsupov, 



nerve; -—/?«, wings) or 

 Nerve - winged insects. 

 Characterized by having 

 the wings reticulate with 

 numerous veins so as to 

 look like net- work. (Fig. 

 9.) The Order forms two 

 natural divisions, the first 

 including all those which 

 undergo a complete, and 

 the second, called Pseu- 

 LiBELLULA THiMAcrLATA. do-neuropt6ra^(^=Dictyo- 



toptera, Burmeister), those which undergo an incomplete metamor- 

 phosis. The latter, when separated, may be considered a suborder. 

 The insects of this Order are, as a whole, more lowly organized, and 

 more generally aquatic than either of the others. A natural arrange-
