Xiphidium brevipcnnis. 



Xiphidmm loyigijicnnis Sciuld. 



Xiphidium lanceolulu7n. 



(Jonocephalus cnsiger Havr. Fairly common. Along with other species 

 of these prominent cone-headed species, it is a conspicuous insect during 

 autumn. 



Conocephalus ncbrascensis Bruner. 



Conocephalus altenuatus. 



Conocephalus crtpitans. A single specimen of this large and interesting 

 species is in the collection of the Agricultural College. 



Scuddcria curvicauda DeG. Usually quite common. 



Seiidderia furculata. 



Scudderia J'urcata. 



Scuddcria pistillata Bruner. 



Aviblycorypha rotundifolia. 



Amhlycorypha oblongifolia. 



Cyrtoiihyllus concavus Say. Not common. 



Thyreonotus pachymerus. A specimen presented by Mr. H. H. Raymond, 

 was collected at Camp Douglas, Wisconsin, so it seems probable that it 

 occurs in the northeastern part of the State. It has never been collected at 

 Ames. 



Ceuthophihis maculatus. Apparently not common. 



Cetctho]ihilus lapidicohis. Not observed as common. The insect recorded 

 under this name by Prof. Bessey proves to be the U. nigra. 



Ceuthophilus divergens. Rather common. 



Udeopsylla nigra. Our largest and probably most common Stone Cricket. 



Udcopsylla robusta. Included on authority of Prof. Bruner. 



Family Gryllid^. 



Triductylus apicalis Say. Seldom found in any numbers, but it may be 

 swept from grass or low herbage in low ground and quite likely is more 

 abundant than supposed, as it is so small as to easily escape notice. 



Xabea bipunclata Fab. Rare, or at least but very seldom taken in the 

 vicinity of Ames. 



(EcMJithus niveus Serv. Often abundant, but the adults have not been 

 taken so commonly as Jasciatus. 



(Ucanthus latipennis Riley. Rare. Probably more common in the southern 

 part of the State. 



fEcanthus angustipennis. Evidently not abundant. But few taken. 



(Ecanthus Jasciatus. Quite abundant. Seems to be our most common 

 form and is taken in numbei's on wild sunllowers during autumn. Possibly 

 the reason it seems moi'e common is because of its abundance on these 

 plants where it is noticeable and readily captured. 



Oecanthus yiigricornis Walk. Specimens apparently of this species occur 

 with other forms, but ai'e perhaps simply very dark forms of fasciatus. 



Neinobius vittatus Harr. Very common antl doubtless often destructive 

 in meadows. It has been observed as especially abundant on hillsides with 

 south exposure. 



Gryllus abbreviatus. Very abundant, both indoors and out. Often 

 injurious to clothing and doubtless destroys a considerable amount of vege- 

 tation, especially while in the larval stages.
