536 NEW York: state museum 



Recorded for Buffalo [Van Duzee, Buf. Hemip. p. 200], Lan- 

 caster, Hamburg, Golden, New York. Specimens are in collections 

 for Albion, Phoenicia and Staten Island. I collected it at Cold 

 Spring Harbor. This is fully characterized by Mr Van Duzee in 

 the original description. It is sometimes quite common but I 

 have never known it swarm in such abundance as some of the 

 species.

Thamnotettix placidus n. sp. 



Somewhat similar to inornata but distinctly more yellowish 

 and with different genitalia. Length of female 5 mm. 



Vertex rounded in front about one fourth longer at middle than 

 at eye, front with lateral margins evenly curved, clypeus widening 

 slightly toward tip, scarcely truncate, lores barely reaching margin 

 of cheek, pronotum broadly rounded in front emarginate behind, 

 elytra hyaline. 



Color a rather deep straw yellow, a little more intense on the 

 vertex and face and tip of py gofers, tip of ovipositors tinged with 

 fulyus, margins of the abdominal segments tinged with fulvus, 

 margins of the abdominal segments, sometimes most of the tergum 

 blackish, tip of beak and a series of median and ventral spots 

 black. 



Last ventral segment of female emarginate, median border 

 faintly striated, pygofers elongate reaching almost to tip of ovi- 

 positor with stiff setae, those toward tip stronger and tinged with 

 fulvus. 



Six specimens collected at Lake Placid by Mr E. P. Van Duzee. 

 It differs from f i t c h i i in the absence of any spots on the margin 

 of the vertex and in the presence of black spots underneath and 

 in the general color which, while hard to describe, is very evident 

 in associated specimens. The shape of the genital segment is 

 also different.
