ties will be found in any locality, but so far 

 as my experience goes the green speci- 

 mens far outnumber the brown every- 

 where and at all seasons. It is a grass lov- 

 ing species as indeed are the group 

 Truxalini generally, being in this re- 

 spect strongly contrasted with the Oedip- 

 odini, which very generally prefer barren 

 hillsides or other localities characterized 

 by somewhat scanty vegetation. The 

 short wings as in allied species are quite 

 variable. 1 have one in my cabinet with 

 elytra and wings quite as long as the ab- 

 domen. Specimens have been taken at 

 Moline as early as the ninth of July, and 

 as late as the fifteenth of October. 



67. Chloealtls conspersa Scudder. 

 Probably found throughout the state, 

 though never abundant and perhaps not 

 everywhere common. The females are 

 very likely to be confused with the 

 brown females of the preceding species 

 from which they may always easily be 

 separated by the slight median carina 

 of the vertex. The wings and elytra as 

 in the preceding species are quite vari- 

 able, one specimen in my collection hav- 

 ing elytra which extend one fourth 

 their length beyond the tip of the abdo- 

 men. The species is noted for the ex- 

 hibition of a habit not possessed by any 

 other member of the family so far as is 

 now known. This peculiarity is its 

 habit of depositing its eggs in holes 

 bored in slightly decayed wood. This 

 fact was first reported by Mr. S. I. 

 Smith in his List of the Orthoptera of 

 Maine. It has since been corroborated 

 by the observations of Mr. C. A. Hart 

 of Champaign.* This species makes its

appearance in spring even earlier than 

 C. viridis; indeed I know of but one 

 other, Pezotettix viridulus Walsh, that 

 is developed earlier from eggs hatched 

 in the spring. It has been found in Mo- 

 line as early as the twenty-first of June 

 and as late as the twenty-fourth of Sep- 

 tember. 



6S. Stenobothrus curtipennis Har- 

 ris. Quite common throughout the 

 state and generally more abundant than 

 either of the two preceding species. It 

 has a decided preference for thick blue 

 grass growing in partially shaded situa- 

 tions. Like its allies it can scarcely be 

 said to either fly or jump, but it sutlers 

 little or nothing in lacking these accom- 

 plishments as its astonishing facility as a 

 tumbler and contortionist generally dis- 

 courage all but the most determined ef- 

 forts for its capture. It appears almost 

 as early in the spring as the preceding 

 species, its first recorded appearance at 

 Moline being the twenty-third of June, 

 and its latest appearance the twenty- 

 fourth of September. 



69. Stenobothrus niaculipcunis 

 Scudd. This very variable species is 

 common in a few localities. It occurs 

 on the ''Sand Hill" several times re- 

 ferred to and described in this paper. 

 It is found too on the barren or sandy 

 tops of the highest hills along the bluffs 

 of the Mississippi and Rock Rivers. It 

 is full-fledged about the first of August. 



70. Syrbula admirabilis Uhler. 

 Widely distributed but rare or uncom- 

 mon. Thomas described the brown 

 form of the male and did not know of 

 the existence of the green form. I have 

 raised from pupae several males which
