There is an Arab logoiul (o tlie cfTect that "A locust iintn Malioinet said : 

 "Wo are the array of the groat (Jod ; we produce ninety-nine eggs; if the 

 liundrod wore completed, wo should consume the whole earth and all that 

 is in it." 



Those luciists or shorl-horiioil grasshoppers are tiio (>rtlioi>tora whicli 

 are so coninion in our meadows and pastures, on our city lawns, and along 

 our roadsides from mid-April until late Novemher. From t!ie eastern 

 I'nited States i;>0 species and 21 varieties of the Family Acrididae are rec- 

 ognized by me. 51 species and ten varieties belonging to the single genus 

 }[clanophis. Of the entire number 50 species and three varieties occur in 

 Indiana, r»2 species and 11 varieties in Florida. 22 species and one variety 

 1 icing common to both states and 50 species and eight varieties of the eastern 

 forms not known from either of the two states. 



FAMILY VII. — Tettigoniidae. — This family, formerly known as Locustidae, 

 comprises our Orthoptera commonly known as katydids, long-horned green 

 grasshoppers, cone-head grasshoppers, camel crickets, stone crickets, etc. 

 Some of the larger green-winged forms — the true katydids — are either 

 known to you in person or through their strident notes, one of them being 

 quoted by Holmes as saying: 



"I sit among the leaves here, when evening zephyrs sigh. 

 And those that listen to my voice I love to mystify ; 

 I never tell them all I know, altho' I'm often bid. 

 I laugh at curiosity and chirrup, 'katy-did.' " 



There are many characters separating the Tettigoniidae from the locusts 

 or Acrididae. one of the most interesting being that the auditory organ or 

 ear Is situated on the basal ring of the abdomen in the locust and on the 

 tibiae of the front pairs of legs in the katydids, as also In the crickets. The 

 males only of the winged forms stridulate. the note being a sexual or love 

 call, but both sexes possess the auditory organ. In the wingless form of 

 all Orthopterons both stridulating organs and ears are absent. As I 

 have mentioned on another occasion before this Academy ; These katydids 

 and crickets were the first musicians of the earth, as by means of their 

 shrilling organs they enlivened the solitudes of the strange old Devonian 

 forests with their love calls and wooing notes. 



Ninety-seven species and 14 varieties of Tettigoniidae are recognized from 

 the Eastern States. 40 species and throe varieties occurring in Indiana, 40 

 species and nine varieties in Florida, ten species and one variety being com- 

 mon to both states and 21 .species and three varieties not found in either. 



FAMILY VIII. — (iRYLLiD.\E. — The Cvickcts. — Some of the members of this 

 family, as the ground and field crickets, are very common insects and famil- 

 iar to all. Others, as the mole crickets, the tree crickets and hush crickets, 

 are more often heard than seen. One of the smallest of our eastern species 

 occurs only in the iiosts of ants. All are chiefly vegetable feeders and in 

 the aggregate do much damage to forage and other crops. 



Forty-seven species and 14 varieties or subspecies of crickets arc known
