tending by its own breadth beyond the front margin of the eyes, beneath with 

 a suba])ical slender transverse fuscous stripe, fading haterally. Lateral lobes 

 of pronotum subangulate in the middle, rounded in front and behind. Teg- 

 mina and ovipositor alike extending beyond the middle of the extended hind 

 tiliia?, the costal vein of the former very slightly divergent from the radial, in- 

 distinct. Fore femora in the female with one subapical spine, middle femora 

 with two, both unarmed in the male. Ovipositor as long as the hind femora, 

 straight, slender, infuscated at extreme apex. Last dorsal segment of male 

 very broadly and subtriangularly emarginate. Anal cerci of same stout, a 

 little arcuate, apically enlarging, with a superior apical tootli dii'ected inwards, 

 beneath which is a hirger subapical, stout, subconical denticle, more strongly 

 incurved and nearly as long as the cerci, terminating in a spine. 



Length of body, male 33 mm., female 35-37 mm.; pronotum, male 8.7 mm., 

 female 8.5-8.7 mm.; tegmina, male 45 mm., female 49-51 nun.; hind femora, 

 male 24 mm., female 27 mm.; ovipositor, female 25-27 mm. 



This species is closely allied to C. dissimilis Serv., C hchcs Scudd., and al- 

 lies, but differs in the length of the ovipositor and the character of the male 

 cerci.

Of the size and general appearance of G. luctiiosux Serv., to whicli it is appar- 

 ently most nearly allied. Piceous, the head with no interantennal stripe, and 

 finely punctate, like the pronotum, which is unrelieved by any variation in 

 color, except that the disk has a pair of faint and obscure minute reddish 

 spots and the hind margin is narrowly dull castaneous. The inner face of the 

 anterior tibia; has no distinctly formed tympanum, but is simply provided with 

 a slight elongate and very slender excavation with no membrane ; it is so small 

 as easily to escape observation, and on this account I was at first incliiied to 

 place the insect in Gryllodes, which the form of the pronotum, the abundance 

 of rhomboidal cells in the dorsal area of the tegmina, and tlie general a.^^^pect 

 will not permit. Legs fusco-rufous, the hind tibia; olwcure. Tegmina a little 

 longer than tlie bodj', blackish i'uscous at base, becoming gradually testaceous 

 apically, the deflected marginal field fusco-luteous witli pallid veins, the space 

 se]iarating the marginal and dorsal fields distinctly luteous; media.stinal vein 

 three-branched, the last branch just before the tip. Wings very long, nearly
