Sitalces albipennis, sj). n. 



An average sized insect, characterized by the small lobate ivory- 

 white tegmina, the oil-green legs, and ш which the genicular por- 

 tion oï tlie hind femora and antennae are terruginous. 



Head about as wide as the anterior edge of the pronotum; the 

 eyes hirge and somewhat prominent, the vertex narrower than the 

 basai joints of the antennae or the frontal costa at its narrowest 

 place, fastigium depressed and ronnded anteriorly, the middle very 

 shallowly silicate; frontal costa prominent i)etween the antennae and 

 nearly twice the width of the narrow vertex, plane above the ocel- 

 lus, gently sulcate below and somewhat narrowed near the trans- 

 verse fascial groove. Antennae rather heavy, tlie basai and second 

 joints not especially robust. Pronotum somewhat expanding posteri- 

 orly, the median carina visible tlirougliout, but not strong, severed 

 by ail tliree transverse sulci which are profound; anterior edge 

 slightly advanced upon the occiput and broadly and roundly emargi- 

 nate at middle, hind margin subtruncate, the middle angulately not- 

 ched; posterior lobe short, less than one-third of the entire length. 

 Tegmina small, elongate oval, their apices not quite reaching the hind 

 niargin of tlie metanotum. Aiiditory ai)paratus nearly or quite obso- 

 lete. Hind femora only moderately robust, not quite reaching the 

 tip of the valves of the ovipositor, the latter rather strongly hooked. 

 Prosternai spine minute, wart-like, upon a large elevated area. Entire 

 insect pale, hirsute, the body sparsely and the legs rather closely so. 



Head back of eyes, thorax above, pleura and dorsum of basai 

 half of the abdomen dark piceous; under side, legs and apical por- 

 tion of abdomen oil-green. Face, the occiput at sides back of the 

 eyes, lower edges and dorsal angles of the pronotum, together with 

 the tegmina and>-shaped patches at middle of the four basai abdomi- 

 nal segments ivory-white, somewhat tinged with green. The lines on 

 pronotum somewhat interrupted. Sides of the abdomen flavous. 



Length of body, $, 15.5 mm., of pronotum, 3 mm., of tegmina, 

 1.1 mm., of hind femora, 8.3 mm. 



1) Possibly this species belongs to the genus Sitalces Stâl instead 

 of to Ommatolampis Burmeister.
