THE CANADIAN ENTOMOLOGIST. 13 



Vertex between the eyes moderately broad, depressed, broadly and 

 quite deeply sulcate, the sulcus broadening gently anteriorly where it is 

 open, with a faint longitudinal carina through the centre ; the lateral walls 

 prominent, rather broadly and roundly angled, highest just above the 

 upper canthus of the eyes ; fastigium coarsely punctate. Frontal costa 

 prominent, nearly equal, as broad as the front edge of the fastigial sulcus ; 

 deeply sulcate throughout. Lateral carinas diverging, reaching the lower 

 corners of the face. Lateral ocelli very prominent, larger than the ocellus 

 of the frontal costa, of a bright amber color. Antennae as long as the 

 head and thorax combined, the basal joint large, as wide as long, second 

 joint pyriform. Eyes of moderate size, rather prominent, nearly globular 

 (male), or with the front edge almost straight (female). Pronotum equal 

 in the male, expanding posteriorly in the female ; median carina slight but 

 visible throughout, most prominent in the female, lateral carina obsolete ; 

 front margin straight, posterior margin slightly truncate, posterior lower 

 angle nearly a right angle. Meso- and metanotum not differing on the 

 dorsum from the basal abdominal segments. Abdomen tapering evenly 

 and gradually posteriorly, sharply carinated ; last segment in the female 

 greatly contracted, valves of the ovipositor exserted, reminding one of the 

 structure of these parts in Tettigidea ; male abdomen with the last ventral 

 segment pointed, the apex squarely docked and slightly but roundly notched. 

 Supra-anal plate a little longer than broad, somewhat triangular, the pos- 

 terior margin gently rounded, the apex slightly produced. Anal cerci 

 cylindro-conical, directed upward and a very little backward, the extreme 

 tip slightly contracted to a rather sharp point. Female cerci cuneiform, 

 directed backward. Posterior femora moderately robust, but not greatly 

 thickened at the base, with all thtj carin^e prominent and sharp, extending 

 beyond the abdomen in both sexes. Posterior tibiae normal ; tarsi with 

 the first and third joints equal. 



General color brownish piceous above, yellowish beneath. Face, lower 

 half of the deflected lobes of the pronotum, and under surface of the 

 body, with the anterior and middle legs ochraceous (female) or citrinous 

 (male). Antennae fuscous. A bright yellow line commencing on the 

 lateral margins of the fastigial sulcus and extending backward on each 

 side of the occiput across the pronotum at the outer edges of its disk to 

 the tip of the abdomen, enclosing along the middle a line of the brownish 

 piceous. Below these, on the sides, a broad stripe of the upper surface 

 color, extending from the hind margin of the eyes to the tip of the abdo-
