58 ORTHOPTEROUS GROUP INSARAE 



The small size and usually short wings of intermedia give the species 

 a different general appearance from any of the other forms. 



Types. — o" and 9; Cordova, Mexico; Guatemala. [All in 

 Geneva Museum.] 



The following description is based upon a male taken at a lo- 

 cality from which the authors have a large series of specimens. 



Description. — cf ; Juan Vinas, Costa Rica. March 1, 1902. (L. Bruner.) 

 [Hebard Collection.] 



Size fairly small for the genus, form rather more compact than usual. 

 Head and eyes very much as in /. tolieca. Pronotum with dorsal length about 

 one and four-tenths the greatest (caudal) dorsal width; dorsum of pronotum 

 slightly depressed within the margins; lateral carinae of dorsum of pronotum 

 distinctly convexo-divergent in the cephalic third, then arcuato-divergent 

 caudad with a decided though obtuse angle : cephalic margin of dorsum 

 of pronotum straight, caudal margin of same arcuate, lightly emarginate 

 mesad, this emargination more pronounced than in tulieca: lateral lobes of 

 pronotum with length less than depth, the ventro-cephalic angle obtusely 

 rounded, the ventro-caudal angle rather broadly rounded, these angles 

 differing less noticeably from each other than in tolteca, the humeral sinus 

 deep, roundly acute-angulate. Tegmina rather short and narrow, the distal 

 width very slightly greater than the mesal width, marginal field as in tolteca; 

 in this specimen the tegmina reach the distal extremities of the caudal femora 

 and are truncate at the apex, less obliquely than in tolteca. Disto-dorsal 

 segment of the abdomen similar to that of tolteca but shorter; supra-anal 

 plate as in that species; cerci short, straight, crassate, scarcely tapering to 

 a blunt apex, the apex toothed, this tooth directed meso-dorsad at a right 

 angle; subgenital plate similar to that of tolteca, very slightly broader. 

 Limbs much as in tolieca, the caudal femora proportionately shorter and 

 more bullate. 



A female bearing the same data as the male described above furnishes the 

 additional information given below. 



Description of Female.- — Somewhat more compact than the male with 

 proportionately shorter tegmina and wings which do not reach the tips of 

 the caudal femora, though the caudal femora are likewise shorter than in 

 the male. Ovipositor similar to that of tolteca; subgenital plate elongate, 

 Bcutiform, considerably emarginate laterad with narrow apex broadly 

 rounded, in transverse section cephalad this plate is W-shaped, rotundato- 

 angulate with the median sulcation shallow, and embraces the base of the 

 ovipositor. 



Color Notes. — The general color of the male specimen described 

 above is a pale shade of raw umber which darkens to mummy 

 brown on face, sides of head, dorsal portion of lateral lobes of pro- 

 notum and proximal portion of the marginal field of the tegmina, 

 and to raw umber on the limbs; this color pattern is practically the 

 same as that found in tolteca and the cephalic and median femora
