Florissant. Two specimens, l>oth apparently females, Xo. 1417"), and 

 tlie one figured, the latter obtained by Mr. Israel C. Russell, of the U. S. 

 ( oMilogical Survey, for \vlnnn the species is named. 



GOMPIIOCERUS Thunberg. 



Heer describes a species of this genus from Oeningen. It is of small 

 si/.e, like most of those of temperate America and Europe, while the species 

 In -re provisionally referred to it is very much larger. I have also seen a 

 species from Aix, labeled as a Gomphocerus by Heer, which may, perhaps, 

 be more nearly allied to Leptysma or Arnilia. Gomphocerus and its nearer 

 .-illics are rather characteristic of, or at least are at present better known 

 from, temperate regions, and are found around the entire globe. (July, 

 1884.) 



GOMPHOCERUS ABSTRUSUS. 



I'l. 17, Fig. (i. 



This species is placed here because of its general affinities as indicated 

 bv the front half of the body, which, as seen on a side view, is all that is 

 preserved. It does not seem, on several accounts, to belong in the genus, 

 lint it plainly comes near it. The head is large and protuberant, with a 

 prominent vertex, sharply angled as seen on a side view, with a rounded, 

 retreating face. Antennae slender, verv slightly enlarged to a faint elon- 

 gated dub at the apex, nearly reaching to the tip of the pronotum. The 

 latter short, with quadrate deflected lobes, the inferior margin straight. 

 Tegmina large, dusky, with the interspaces between the longitudinal veins 

 broken at base by straight cross- veins into pretty regular square or sub- 

 quadrate cells. 



Length of fragment, 21"""; of head, 4.5""" ; length of face, 5-5 mm ; 

 length of antennae, 8 mm ; of pronotum, ")"""; height of same, 4""". ' 



Kloris.-ant. One specimen, Nos. 600 and 1173(>. 







Subfamily CEDIPODID^E Stal. 



To this subfamily belong most of the fossil Acridii and half of the 

 American species. Heer iii his Tertiiirgebilde and his I'rwelt der Schweiz 

 describes hall' a do/.en species from Oeningen and Radoboj, referring them 

 all to tin oM genus <Kdipocla. Serres mentions a species from Aix which
