10. Thamnotettix limbata n. s]?. 



Above dark brown; costal margin of the ehtra and all beneath j-ello\v. 

 Vertex produced, subacute. Length 5 mm., male. 



Head a very little wider than the pronotum. \'ertex flat, its length equal 

 to its breadth on the hind margin, and scarcely less than the length of the 

 pronotum; before produced to a subacute point; passage to the front rounded. 

 Front slightly reflexed above, almost encroaching on the disc of the vertex 

 before; ocelli placed at about one-third the distance from the eye to the tip 

 of the vertex and well up on the anterior rounded edge of the head, distinctly 

 visible on the margin of the vertex when viewed from above. Sides of the 

 front almost straight. Clypeus broad, rounded at the extremity, a little con- 

 stricted near the base. Lorae long, of moderate width. Cheeks narrow, sides 

 nearly straight, a little waved below the eyes, exterior to the lorae very nar- 

 row. Elytra long and narrow; costa feebly convex, costal area with several 

 supernumerary transverse nervures near the apex. 



Color: Head pale yellow; front embrowned, a few transverse arcs above 

 and the central line, pale; vertex washed with brown, before the posterior 

 margin with two short oblique lines placed near the eyes and an abbreviated 

 central impressed line, darker brown, eyes black. Pronotum clear pale 

 brown, darker on the anterior margin, where there are some irregular pale 

 lines forming an annulus behind each eye and leaving two brown points on a 

 pale area at the apex. Scutellum brown, darker than the pronotum. Elytra 

 blackish brown; broad costal margin bright sulphur^yellow, before the apical 

 areoles with three or four small hyaline cells formed by a few extra transverse 

 nervures; discal nervures pale brown, paler toward the apex on the yellow- 

 costal area concolorous. Wings smoky iridescent, with brown nervures. 

 Beneath clear yellow; dot at the base of the tibial spines and apex of the 

 tarsal joint blackish. Abdomen black, narrow margin of the tergum and 

 the venter yellow; plates with an abbreviated blackish central line at base, 

 the tips infuscated. 



Genital pieces: Valve very short and broad, apical margin a very little 

 convex; plates long, gradually narrowed to the apex; margin heavily fringed 

 with long white hairs, especially toward the base; submargin with a row of 

 about ten stout spines; apex of the pygofers with a dense cluster of similar, 

 but larger spines. 



Described from a sinyle male example (No. 612). In general 

 form this insect has much the appearance of a small Tettigonia, 

 while in the position of the ocelli it approaches Acocephahis. It 

 appears to sustain about the same relationship to Thamnotettix as 

 does the genus Anoterosteiiima L. to Athysanus, but the former 

 genera are perhaps less widely differentiated than the latter. 



11. AUygus inscriptus n. sp. 



IJroad oval, or almost oblong. Pale testaceous, more or less tinged with 

 yellowish on the vertex, irrorate with darker on the thorax; elytra clouded 

 w'ith fulvous; marked with whitish on some of the basal areoles and trans- 

 versely banded with the same color near the middle, the fulvous areas spar- 

 ingly inscribed. Length 4 — 5 mm. 



Head scarcely narrower than the pronotum. Vertex bluntly triangular, 

 about two-thirds the length of the pronotum, the apex obtusely rounded;
