93. Pezotettix manca Smith. This 

 species is put in the list of Illinois Or- 

 thoptera on the strength of a single pair 

 of specimens taken at Running Lake 

 July 15, 1SS3. 



94. Tettix cristatus Harr. Accord- 

 ing to Bolivar x Batrachidea carinata 

 Scudd. is a synonym of B. cristata Harr. 

 and the latter is transferred to the genus 

 Tettix. I have a single specimen from 

 Bloomington. 



95. Tettix triangularis Scudd. I 

 have seen but two specimens from this 

 state ; both are in my collection, one 

 from Rock Island and the other from 

 Bloomington. 



96. Tettix granulatus Kirby. I 

 have a specimen from Brookeville, Ind., 

 and one from Moline, which I refer to 

 this species. 



97- Tettix ornatus Say. There is a 

 single specimen in the museum of the 

 State laboratory of natural history from 

 Bloomington, 111. which belongs to this 

 species. I have a specimen from Bloom- 

 ington, Indiana, which I place here. 

 While these four species are all found in 

 the state it is pretty evident that they are 

 all rare, since out of all the hundreds of 

 Tettiginae examined by me these seven 

 individuals are all that I have seen of 

 these species from Illinois or Indiana. 



9S. Tettix arenosus Burm. I refer to 

 this species a large number of Tettix 

 collected at various times by Mr. C. A. 

 Hart of Illinois University and a lim- 

 ited number of specimens that I have 

 collected in the north-western part of the 

 state. I have formerly been accustomed to

 par Ign. Bolivar. Gand, 1SS7. 



consider this form as T rugosus Scudd. 

 but these specimens seem to be indistin- 

 guishable from T. arenosus Burm. as 

 Mr. Scudder understands this species, 

 and they do not seem to belong to the 

 new genus Paratettix in which Bolivar 

 places T rugosus Scudd. Besides 

 this species is too nearly allied to T. cu- 

 culatus Burm to allow of its being put 

 in a different genus. I am tempted to 

 risk the opinion that T arenosus and 

 7. rugosus are too much alike to re- 

 main in different genera, if they are 

 really different species. I have mature 

 specimens that have been taken in every 

 month from March to September inclu- 

 sive, a fact which would seem to indicate 

 that there are two or more broods of this 

 species in a year, or that their breeding 

 time is so irregular that they can not be 

 divided into broods at all. 



99. Tettix cuculatus Burm. This 

 species is represented by numerous spec- 

 imens taken in Rock Island and neigh- 

 boring counties and by a few in Mr. 

 Hart's collection. They were taken 

 during the months of May, June, July, 

 and August; I have three pupae taken 

 at Hampton on May 5th and four taken 

 at Moline, one on the 5th and three on 

 the 8th. These pupae taken at about the 

 same time in different localities are all 

 ready to moult for the last time. This 

 regularity would indicate that the)- have 

 developed from eggs hatched in the 

 spring, and if this is the case the title of 

 Pezotettix viridulus Walsh to be the 

 first grasshopper to be developed from 

 eggs hatched in the spring will be in 

 some danger.
