Paratettix texanus Hanc. C. (Coll. I. S. L. N. H.); H., 3, more seen. 

 Near the small stream. 



P. texanus nanus Hanc. H., 2. This is quite possibly a distinct 

 species. 



Tettizidea laterals Say. C. (Coll. I. S. L. N. H.) ; H., i. 



Syrbula admirabilis Uhl., October 28th (Coll. I. S. L. N. H.)- H., i. 

 Much larger than Illinois examples. 



Mesochlora abortiva Brun. C., 14 cf, 28 $ , i young; B., 4 9. One 

 of the commonest species about College Station, on the dry, thinly 

 grassed sides of stream hollows. 



Mesochlora unicolorn. sp. C., 8 tf, n 9 ; B., i J 1 . Associated with 

 the preceding, and not differing appreciably from it except in the dorsal 

 sculpture and coloration ; the two not intergrading, however, in the series 

 obtained. 



Readily recognized by the uniform gray of the tegmina and dorsal sur- 

 faces of head and pronotum, the lateral carinae uniform throughout, not 

 partly swollen, at middle less sharply curved than in abortiva, and 

 usually separated here by more than half the distance between them at 

 the posterior margin. The pronotal lateral black spot and oblique carina 

 are about as in abortiva. 



In abortiva, on the other hand, there is a velvety black line on the 

 tegmina, sometimes broken, and two straight stripes of this color on the 

 head and pronotum above. On the pronotum these include the strongly 

 clepsydral lateral carinae, the convergent portions of which are straight, 

 swollen, and ivory-white, connected by a fine short arc, the carina.' here 

 separated by about half the distance between them on the posterior 

 margin. Type in collection of 111. State Lab. of Nat. Hist. 



Amblytropidia occidentalis Sauss. C., i ; H., 23. Abundant among 

 the pines, very elusive, flying short distances noiselessly and almost in- 

 visibly, the dorsal color closely matching that of the fallen pine needles. 



Orphulella pelidna Burm. C., 24, i nymph; B., i; H., 36; G., 6. 

 Widely distributed and common in short grass. Galveston examples 

 are mostly a little shorter winged and greener, suggesting the next. 



O. picturata Scudd. C., 12; B., 6. With the preceding. 



Dichromorpha viridis Scudd. H., 2. Green variety. 



Arphia xanthoptera Germ. C., i ; H., 4. 



A. simplex Scudd. H., 8 ex. With the preceding on dry sunny open 

 spots in woods. 



Chortophaga viridifasciata DeG. C., 12; B., H., 5; G., 10. Many 

 others seen. The green form is rarer than in Illinois. Both sexes were 

 seen to produce the crackling sound in flight. I was struck by the 

 abundance and activity of both young and adults. They seemed thor- 

 oughly at home at this season. 



Encoptolophus cos/a/is Scudd. C., 3 ; B., 4 ; H., i. On bare dry ex- 

 posures of washed-out roads or stream banks.
