March, 1906.] CAUDELL : CyRTOPHYLLI OF THE UNITED STATES. 41 



Cyrtophyllus furcatus, new species. (PI. I, fig. 9.) 



Male only known. Practically indistinguishable from C. perspicillatus except 

 by the cerci, which are remarkably different. The lower branch is scarcely at all in- 

 curved apically and is without a ventral subapical dentical but is armed about the 

 middle on the inner side with a black-tipped branch about as long as that portion of 

 the cercus beyond it. The two branches are also somewhat more divergent. 



Length, pronotum, 6; elytra, 37; posterior femora, 21.5; sub- 

 genital plate, 17; width, pronotum, 6.5; elytra, 18.5; subgenital 

 plate, 2.75 mm. 



Type no. 9136 U. S. National Museum. 



One male, West Point, Nebraska. 



The very unusual structure of the cerci of this form makes it quite 

 unadvisable to consider it other than a valid species. The color is red- 

 dish brown rather than green, but this is evidently due to discolora- 

 tion as the same is true of some specimens of other species. 

 Cyrtophyllus intermedins, new species. (PI. I, figs. 2, 8.) 



Somewhat allied to both perspicillatus and elongatus, to the former by the longer 

 posterior femorse and more nearly to the latter by the smaller size, the indistinct trans- 

 verse sulci of pronotum and the narrow elytra of the female. The cerci of the male 

 are different from those of either of the allied species, the lowei branch being shorter, 

 with the apical incurved portion about as long as the basal portion, which is thick 

 and uniformly tapering ; the cerci between the upper and lower branches is much en 

 larged, more so than in any other species seen, forming a triangular lobe (Fig. 8) 

 The elytra of the single female specimen seen are peculiar in having the posterior 

 margin, when the elytron is spread, nearly straight, the tip narrowly rounded ( Fig. 2) 

 The transverse sulci of the pronotum are shallow and obscure. 



Length, pronotum, male, 5; female, 5.5; elytra, male, 34 

 female, 35.5; posterior femora, male, 21 ; female, 21.5; subgenita 

 plate, male, 13 ; ovipositor, 18 ; width, pronotum, male, 6 ; female, 

 6; elytra, male, 18; female, 14; subgenital plate, male, 2.25; ovi- 

 positor, 3.25 mm. 



Type no. 9137, U. S. National Museum. 



One male, Biloxi, Mississippi (Alice Tracy) ; one female, Wells- 

 boro, Texas (N. Banks). July 18, 1903. 



This seems to be a southern species. It appears unquestionably 

 distinct, not being referable to either of the allied species. The 

 female is especially closely allied to some of the females of C. oblon- 

 gatus in which the anal margin of the elytra is less convex than the 

 costal margin. The elytra of this species must be spread to properly 

 exhibit the shape, the straight anal margin not being obvious when 

 the elytra are folded.
