the base ; pygofers exceeding the plates, obtuse. Ultimate ventral seg- 

 ment of the female rather long, hind edge rounded with a short, abrupt 

 median projection or tooth, about twice as broad as long ; pygofers broad, 

 a little surpassed by the stout ov^iduct. 



Colour : Entire insect pale greenish-yellow, polished, paler on the head 

 and beneath, tips of the tarsal joints embrowned, extreme apex of the 

 rostrum black, anterior edge of the head with a round black spot placed 

 just above and within each ocellus, and two minute equidistant brown 

 points between these on the apex. Mesonotum and sometimes the basal 

 tergal segments black. Eyes brownish. Elytra subhyaline with strong 

 yellowish nervures. 



Colorado. Described from two male and four female examples received 

 from Prof. C. P. Gillette. Except in its want of ornamentation this 

 insect is closely related to Eiitettix seminuda, Say, like which it 

 approaches Thamnotettlx in many of its characters. But its broader 

 form, the characters of the vertex and the wide front will indicate its 

 relationship. 



4. CiCADULA LEPIDA, //. Sp. 



Very near C. diminuta, Leth., but larger, with the front narrower and 

 less tumid below, and with the clypeus broader at apex. Length, 31^ to 

 4 mm. 



Colour pale yellow somewhat intensified on the abdomen and tinged 

 with green on the vertex. Head marked with two points placed near the 

 hind edge of the vertex about midway between the nearly obsolete 

 median line and the eyes, two large transverse spots at apex, on the 

 basal sutures of the front. A vertical mark either side between the 

 ocellus and eye, about three very short frontal arcs, and a spot at base of 

 the antennae ; all black. Eyes, frontal sutures below the antennse, tips 

 of the tarsal joints and a row of minute points at the base of the tibial 

 spines, brown. Disc of the tergum, oviduct, claws and tip of the rostrum 

 black. Elytra whitish, pellucid, faintly tinged with yellow at base and 

 smoky at tip ; nervures slender, pale yellow. Wings white. Last ventral 

 segment short, hind edge entire, very slightly rounded ; pygofers bearing 

 a few white bristles at tip, scarcely surpassed by the oviduct. 



Described from two female examples, Kansas, July, Prof. F. H. 

 Snow. New York City, June, Mr. E. B. Southwick. Prof. Snow's
