4 ENTOMOLOGICAL NEWS. [Jan., 'l8 



Length 8-10 mm.; width 2.5-3 mm - Vertex, length slightly greater 

 than two-thirds width, disc slightly convex, sloping in line with pro- 

 notum, medially weakly carinate, laterally depressed, margins between 

 eyes and tylus deeply sulcate and somewhat reflexed; tylus deeply in- 

 serted, disc distinctly elevated with depressions lateral to weak median 

 carina, anterior margin rounding-angulate and produced; ocelli placed 

 close to posterior margin of vertex, equidistant from each other and 

 from posterior margin of tylus; front broadly rounded, acutely angled 

 with vertex, inflation a slight curve, disc narrowly flattened in median 

 line. 



Pronotum, disc weakly convex, medially weakly carinate, anterior 

 margin broadly rounded, lateral margins short, equalling distance be- 

 tween ocelli, parallel, posterior margin deeply emarginate; elytra cori- 

 aceous, twice longer than wide, parallel margined, closely and finely 

 punctate, the punctures setigerous. 



Genitalia : Female, last ventral segment one half length of preceding, 

 convex; pygofers broad, length equalling combined basal width, outer 

 margins incurved throughout basal third and indented at middle, ex- 

 ceeded by stout ovipositor one-half their length. Male, last ventral 

 segment twice length of preceding, convex; plates curved dorsally at 

 nearly right angles to abdomen, long, broad at base, laterally extended 

 here to one-half width of last segment, obtusely notched to one-half 

 basal width at end of basal third, thence tapering to tip as cylindrical 

 processes, black, sparsely clothed with white hairs. 



Color: Pale yellow: stripe from anterior margin of tylus, medially 

 across vertex and pronotum, and along suture of elytra to apex, stripe 

 extending from eye across lateral margins of pronotum, following 

 and fading out posteriorly along outer sector of elytron, and sulcate 

 anterior margin of vertex above and below, dark brown to black; 

 front with disc laterally coarsely ribbed with light chestnut-brown. 



Described from seven specimens collected in Wisconsin and 

 received through the kindness of Mr. D. M. DeLong. Three 

 male specimens collected at "Medina, Wise., 8-23-16" were 

 swept from sedges at the edge of a tamarack swamp ; one male 

 and three female specimens collected at "St. Croix Falls. 

 Wise., 8-15-16," on the St. Croix River, were swept from sim- 

 ilar sedges in a swampy hollow in the State Forest Park Re- 

 serve. Neither of these localities had ever undergone culti- 

 vation apparently. Type, $ , St. Croix Falls, in author's col- 

 lection ; paratypes in collections of Prof. Herbert Osborn and 

 Mr. D. M. DeLong, Ohio State University, Department of 

 Entomology, Columbus, Ohio.
