torulin,q by its own breadth beyond t]ie front niarf,'in of tlie eyes, beneath witli 

 u suba]ncid .slender transverse fuscous stripe, fading hiterally. Lateral lobes 

 of pronotuni subanf,nilate in the middle, rounded in front and behind. Te-;- 

 mina and ovipositor alike extending be)'ond the middle of the extended hind 

 tibiae, the costal vein of tiie former very slightly rlivergeut 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 Ijroadly and subtriangularly emarginate. Anal cerci of same stout, a 

 little arcnate, apically enlarging, with a superior apical tooth directed inwards, 

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

 incurved and nearly as long as the cerci, terminating in a si)ine. 



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 mm.; hind femora, 

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



This species is closely allied to C. dissimilis Serv., C. hcbes 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. luctuosua Serv., to which 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 tiljia; has Jio distinctly formed tympanum, but is sinijdy 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 inclined 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 the general aspect 

 will not permit. Legs fu.sco-rufous, the hind tibia; oltscure. Tegmina a little 

 longer tlian the body, blackish fuscous at base, becoming gradually testaceous 

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

 separating the marginal and dorsal fields distinctly luteous; mediastinal vein 

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