NOMOTETTIX SINUFRONS, HAN'C. 



>t 



Body a little compressed, rugose, granulate; crown mani- 

 millate posteriorly between the eyes, occiput considerabh- 

 exposed. Vertex fully twice as wide as one of the e3'es, rugose, 

 in profile distinctly higher than the eyes, and strongly pro- 

 duced in front of them; median carina distinct anteriorly, 

 obliterated posteriorly, ]5rojecing a little from the middle of 

 the convex front border; on either side of the median carina 

 of the vertex shallowly fossulate or subdepressed between the 

 anterior half of the eyes; viewed in front the frontal carinae 

 substraight. Frontal costa moderately sulcate, rami parallel, 

 in profile strongly advanced in front of the eyes, a little sinu- 

 ate between them, face a little retreating. Pronotum rugose, 

 granulate, antero-dorsal margin angulate, the sides of the 

 angle subconcave, in profile anteriorly produced scarcely 

 beyond the posterior border of the eyes; dorsum between the 

 shoulders narrow, humeral angles widely obtuse, posteriorly 

 the process cuneate, reaching about as far as the knee of the 

 hind femora; median carina of pronotum distinct, compresso- 

 carinate, longitudinally rather low subarcuate, highest between 

 the shoulders, lateral carinae indistinct. Wings not reaching so 

 far as the apical process; elytra narrow, subacuniinate. Femoral 

 margins entire; posterior femora stout, the first article of the 

 posterior tarsi much longer than the third, serrulate above, 

 pulvilli flat below. 



Body, 5 9.5 mm.; pronot., 8.5 mm.; post, fern., 6 mm. 



Locality, Minnesota, St. Anthony Park. (Lugger.) 



This species is nearly allied to X. cristatus, differing from 

 that species principal!}' in the body being a little more rugose; 

 the vertex a little wider and more flattened, coarsely granu- 

 late, convex at the anterior border, the median carina of vertex 

 less distinct and but little projecting, the occiput more uncov- 

 ered; the facial frontal costa less sinuate; the face more 

 ampliate; the pronotum, while anteriorly angulate, projects 

 but little over the head; the median carina of pronotum less 

 thinly cristate and in profile longitudinally presenting a lower
