Genus TETTIGONIELLA Jacobi 



Tettigoniella whiteheadii Distant. 



Very pale ochraceous throughout ; tibiae and tarsi slightly dark- 

 ened; 2 small black dots at tip of vertex, 2 spots on margin 

 anterior to ocelli, 1 large median angulated black spot connected 

 with basal margin of vertex by a median stripe, a variable median 

 stripe on pronotum and scutellum, entire commissural margin of 

 tegmina narrowly, and principal sectors of corium, dark brown 

 to black. Tegmina concolorous, becoming smoky subhyaline api- 

 cally. Length $ 9.5, 9 11 mm. 



Length of face somewhat less than twice width between eyes. 

 Face strongly swollen; the disc of front flattened, lateral areas 

 with numerous transverse darker stripes, the upper angles of 



the front, and the upper

angles of the flattened area, 

 each with subtriangular black 

 spots — extensions of those on 

 the vertex. Face and vertex 

 very finely shagreened. Head 

 tumidly rounded in front, the 

 anterior portion of vertex 

 strongly convex, posterior 

 third with a strongly im- 

 pressed complete transverse 

 area in which the ocelli are 

 placed. Length of vertex 

 somewhat more than half 

 width between eyes, slightly shorter in the male; anterior 

 margin slightly incurved at eyes, much more strongly so in 

 the male. Ocelli just behind the line of the anterior margins of 

 the eyes, distinctly long oval in shape, and twice as far from the 

 median line as from the eyes. Pronotum with a few scattered 

 weak punctures and with very indistinct transverse wrinkles, the 

 anterior third with a deep oblique groove on either side of median 

 line. Scutellum about as wide as long, large acuminate-tipped. 

 a little shorter than pronutum, the sharp transverse impressed 

 line near middle of disc. Last ventral segment of female some- 

 what produced and strongly narrowly rounded.

This species presents a remarkable superficial resemblance to 

 Tettigoniella spectra var. nigrilinea Stal, and specimens may be 

 found under that name in collections. But apart from minor
