6. Gryllotalpa ponderosa n. sp. (?) There is a single specimen of a 

 second species of mole cricket contained in the collection, from the same 

 gentleman. This insect is greatly damaged, having the entire head and 

 part of the front edge of the pronotum missing. It is the largest speci- 

 men of the genus that has ever come under my notice, and may prove to be 

 new. I have labeled it Gryllotnlpa ponderosa. Its distinguishing char- 

 acteristics, so far as can be seen, are its great size, length of tegmina and 

 wings, the venation of the former, and the evenness of the dactyls or claws 

 of the front legs. Length of body still remaining, 40 mm. ; of tegmina, 

 21 mm. ; of wings, 41 mm. ; of pronotum, 12 J mm. ; width of pronotum. 

 8 mm. 



7. Oryiius luctuosiiH Serv. Several specimens of immature insects from 

 Barber and Shawnee counties (Cragin). 



8. Gryiius neglectus? Scudd. Several specimens from Topeka (Cragin) 

 and McPherson Co. (Dr. John Rundstrom) are referred here with some 

 doubt. 



Most of our so-called North American species of this genus appear to 

 run together, the only characters upon which some of the species are es- 

 tablished being the variation in the length of the ovipositor io the females, 

 and a few other such unreliable characters. 



9. Oryiius personatus Uhler. A few immature specimens collected in 

 McPherson Co. (Rundstrom) are referred to this species. 



Mr. Saussure, in his great work on the Gryllidse., says this insect is 

 probably a variety of the Grylms domesficus of Europe. 



10. Nemobins vittatus Harr. Topeka (Miss Mara Becker, Cragin.) ; 

 McPherson Co. (Ruridstrom) ; Barber Co. (Cragin). 



The genus Nemobius, like Gryllus, is composed of insects so closely re- 

 lated that it is with the greatest difficulty the species are separated from 

 one another. 



11. moiius sp. Topeka (Cragin). 



There is a single specimen of a second species of Nemobius among some 

 recently received material. This cricket is much smaller and lighter colored 

 than N. vittatus, and is also somewhat irregularly mottled with very dark 

 brown or black. It occurs in the woods among fallen leaves and other 

 debris, and is very active. This may be one of Mr. Scudder's species, but 

 I will reserve decision upon it for a future report. 



12. <Ecanthus niveus Serv. This species, which is one of the common- 

 est of Gryllids, in Kansas, is represented by but a few specimens from 

 Topeka, Great Bend, and the Gypsum Hills. Barber Co. (Cragin). 



The genus (Ecanthus is also one in which the species are very variable, 

 and pass into one another almost imperceptibly. 



LOCUSTID^E. 



13. ceuthophiius maciiiatus Say. Represented by a pair of defective 

 specimens from McPherson Co. (Rundstrom). 



14. Ceuthophilus pallidus Thos. A single male from Topeka (Cragin) 

 is referred here. 



15. Ceuthophilu* sp. Topeka (Cragin).
