blackish, the female genital segment with broad triangular exca- 

 vation within which the ligulate process shorter, not longer than 

 segment. Length ? 6mm, ^ 5 . 5mm. 



Head broad, vertex about one and • one 

 half times as long at middle as at eye; sub- 

 angulate, front narrowing evenly to clypeus, 

 clypeus rounding at apex. Lores elongate, 

 cheek rather broadly rounded at the sides, 

 pronotum rather strongly arcuate in front, 

 truncate behind. 



Color. A deep fuscous black, vertex except 

 at base, posterior part of pronotum, elon- 

 gate spot on elytra, bright lemon yellow; 

 costal half of elytra light yellowish, tran- 

 sparent, terminating abruptly and squarely 

 near the apex ; face and beneath light yellow ; 

 two conspicuous oval black spots just below 

 the vertex almost meeting at the apex of the 

 vertex. Small spot at base of antennae black. 



Genitalia. Last ventral segment of female 

 broad, with deep triangular excavation includ- 

 ing a short ligulate process not reaching the 

 hind border of the segment. Py gofers with 

 rather coarse bristles, ovipositor reaching tip 

 of pygofer and of the same color. Male 

 valve small, plates elongate, triangular, acu- 

 minate, reaching beyond pygofer, the border fig. 24 Thamnotettix

They occurred on underbrush but the particular food plant, if 

 they are confined to a single species was not determined. The 

 species has such a striking resemblence superficially to c li t e 1- 

 1 a r i u s that it is perhaps not strange that its distinctness has 

 been overlooked. Moreover, it is very rare in collections and per- 

 haps its occurrence in deep wood is responsible for this. 



Three specimens of this species were observed also in Cornell 

 University collection associated with clitellarius and a single 

 specimen has stood for some years in the O. S. U. collection having 

 been collected at Ithaca N. Y., by Mr J. S. Hine, This specimen 

 bearing the determination of clitellarius by Mr Van Duzee. 



The species may be at once separated by the genital character 

 and furthermore by constant difference in shape of vertex, position 

 of spots under vertex, shape of sutural spot and transparent costal 

 area and blacker color. 



The known distribution so far has been limited to the two points 

 mentioned — Hamburg and Ithaca N.Y.
