Tettix ornata, Harris, Ins. Inj. to Veg., 1S62, 186. (Not 



Tettix ornatus, Say.) 

 I have found this species in both Vigo and Fulton counties, and McNeill, 

 loc. cit., has recorded it from Franklin Co., Ind. 



In Vigo Co. it is evidently scarce, as I have taken it only in winter 

 from beneath logs, in the vicinity of the large pond mentioned above, 

 nnd&r Au/ocara Scudderi. In Fulton Co., 150 miles north, I found it 

 very common in the depths of a tamarack swamp, in company with 

 Tettigidea polymorpha, Burm. 



In life, the inner wings of gramdatus are bluish or bottle green, a 

 character I do not remember to have seen noted by any previous writer. 



It is an insect of wide distribution, extending from ocean to ocean, 



and northward through British America. Vigo county is probably near 



the southern limit of its range.

NOTES ON SOME OF THE SPECIES MENTIONED IN THE PREVIOUS PAPERS. 



Leptysma marginicollis, Serville. (C. E., XXIV., 28.*) 



The only habitat of this species in Indiana, known to date, is the 

 margin of the large river bottom pond mentioned in my previous paper. 

 This has been partially drained, and, as a result, the locust was quite 

 scarce in the autumn of 1893. I was much surprised, however, to find 

 there, on May 21st, a fully developed male, with soft, flabby wings, as 

 though just moulted, though no others of any age were seen on that date. 



Truxalis brevicornis, Linn. (C. E., XXIII., 75.) 



This has proven to be a rather common species about the margins of 

 marshes, ponds and lakes. In Vigo county it reaches maturity about 

 August loth. It has been taken in Fulton and Marshall counties, thus 

 extending its known range 150 miles northward. 



Chrysochraon viridis, Scudder. (C. E., XXIII., 75.) 



The brown form of this species far outnumbers the green one in this 

 locality. It has been taken in copulation as early as July 15. The spring 

 and early summer of 1892 were very damp, it raining almost every day in 

 the month of May. In the lallcr part of July hundreds of dead and 

 dying specimens ot this species and of Melanoplus biviitatus, Say, were

 mentioned by myself.
