we find upon the specimens taken of either variety, these being often either 

 plain green or dull brown throughout. Even in central Nebraska, speci- 

 mens of the typical virginianns are of rare occurrence, while in the southern 

 part of the State it is by far the commonest form. I have noticed that 

 the form infuscata is generally found early in spring while the green ones 

 are more common later in the year. This I can only account for by the 

 larvae wintering over and imitating the color of the dead leaves, etc.. among 

 which they conceal themselves a trait very common among different mem- 

 bers of the order Orthoptera. 



Dr. Saussure, in his recent work on the (Edipodini of the world, has 

 erected a new genus for this and two allied species, which he calls Chorto- 

 phiga. I see no need for this, as it was separated from the balance of the 

 (Edipodse, by Mr. Scudder, and made the type of the genus Tmgocepli'da, 

 which last name, being preoccupied in the Coleoptera, was replaced by the 

 present. 



47. Encoptoloplms sordidus Burm. McPherson Co. (Rundstrorn) ; 

 Topeka (Miss Becker, Mrs. Oagin, Prof. Cragin). 



48. Hippiscus i n-osus Scudd. McPherson Co. (Ruridstrom) ; Topeka 

 (Miss Becker, Prof. Cragin); Labette Co. (Newlon) ; Finney and Barber 

 Cos. (Cragin). 



49. Hippiscns discoideus Serv. Several specimens of this species are 

 in the collection from Topeka (Cragin). 



Dr. Saussure, in his late work on the (Edipodini, places this species as 

 a synonym of the H. phcenicopterus of Burrneister, and makes the insect 

 which we always have relegated to the last name, If. tuber culatus Pal. 

 de Beauv. In this he may be correct, as he has the facilities for examining 

 the types of these various authors; and if this be true, hereafter we shall 

 be obliged to drop Serville's name for that of Burmeister, which has 

 priority. 



Hippiscus discoideus and H. phoenicopterus have always been considered 

 as separate species by me. I also have specimens of what I take to be H. 

 tuberculous in my collection. These latter are from Florida, while my 

 supposed discoideus and plioenicopterus both occur here, and belong to the 

 same subgenus with a fourth species that I have taken in the Big Horn 

 Mountains of Wyoming. This last species has been referred to Prof. 

 Thomas' (Edipoda paradoxa, and if I am correct in this determination, 

 will hereafter be known as Hippiscus paradoxus Thos. With us in cen- 

 tral Nebraska, discoideus and phcenicopterux winter in the larval state in a 

 similar manner with Tragocephala viridifasciata and several of the Arphias. 

 H. phoenicopterus always has the disc of the wings red, while in discoideus 

 there are occasional specimens with yellow wings ; there is also more of a 

 contrast in the sizes of the sexes in the latter than in the former species, 

 where there is but little difference. 



I think there will be no harm, while speaking of the species belonging 

 to this particular group, to say a few words in reference to Dr. Saussure's 

 arrangement of all the large mottled (Edipodini native to this continent. 

 He divides them as follows : 



HIPPISCUS. Antennae thread-like, but little compressed or flattened in 

 the male, of medium length.
