Elytra: Color and basic pattern similar to n. notatus, but basal spot 

 always attaining scutelhim and apical spot joining latter at about 

 sixth to eighth intervals ; punctation similar to that of n. notatus. 



Prosternum: Male with anterior margin produced downward into 

 a sharp, distinct spine; female with anterior margin produced down- 

 ward into a pointed lobe. 



Length: 3.6 to 5.1 mm. 



Discussion. — Three female cotypes are in the U.S. National Mu- 

 seum. The specimen bearing Schaeffer's determination label has the 

 data "Tex." and is hereby designated lectotype; it is assigned USNM 

 type number 69094. The pins of each of the two cotypes have a black 

 strip of paper but no collection data. In the original description, the 

 collection data are given as "New Braunfels, Texas, (O. Dietz)." 



Collection information includes mating and feeding on willow, 

 damaging strawberries, on blooming live oaks, and on Quercus sp. 



Distribution. — The 81 individuals in the USNM collection are 

 from Pennsylvania, Indiana, Nebraska, Kansas, South Dakota, 

 Texas, Oklahoma, Colorado, Utah, Minnesota, Quebec, and Manitoba.

 apical margins light orange to yellowish; pronotum sometimes uni-

 usually with two longitudinal vittae, orange to dark reddish, some- 

 times black in part, vague to rather distinct but not sharply delim- 

 ited. Vittae of each elytron from bases of second, third, and fourth 

 interval to apex of second interval and from humenis to apex of fourth 

 to eighth intervals; inner vitta rarely black at base, outer vitta some- 

 times black at base and apex to nearly black throughout; rarely with 

 no trace of vittae. With nine rows of punctures, fifth to eighth rows 

 crowded, sixth and seventh usually somewhat confused; punctures 

 often larger, nearly always more distinctly impressed than usual, 

 finer apically; intervals, especially at sides, distinctly convex; inner 

 and outer rows quite distinct at apex, always clearly uniting.
