45. S. oronoensis Metcalf. One larva collected by L. G-. Gentner 
at Eau Claire, June 4, 1917, later pupated and within 
three weeks a perfect male adult appeared. All three 
stages of this species agreed with Metcalf’s full descrip¬ 
tion. 
46. S. fisherii Walton. Two males, numerous females. July to 
September. Dane and Milwaukee Counties. Figures 37, 
38. The Wisconsin specimens have the antennae and the 
facial stripe deep black, not brown; pile of thorax very 
short, longer on the sides, whitish, that of the scutellum 
short and mostly black; black of second segment mostly 
opaque. 
(S. umbellatarum) . The specimens labeled as this species in 
the Milwaukee Public Museum are fisherii Walton. 
47. S. disjectus Will. One specimen, Dane County, September 3, 
1917. Specimens in the Milwaukee Public Museum labeled 
disjectus belong to Xanthogramma fragila n. sp., loc. cit. 
48. S. species no. 1. Two specimens, Dane County. Figure 39. 
49. S. arcuatus Fallen. Vilas, Milwaukee, Dane, Burnett, and St. 
Croix Counties. Early spring. Figure 40. 
50. S. perplexus Osburn. Numerous specimens from Dane County, 
taken in early spring only. Figure 43. 
51. S. species no. 2. Two males and two females, all taken at 
Madison, May to September. Figure 42. These speci¬ 
mens are very closely related to diversipes. 
52. S. nitens Zett. Dane County. Early May only. Figure 43. 
This species has been recorded from Maine. I have been 
unable to separate this species from abbreviatus Zett. 
Can they be the same species ? 
53. S. abbreviatus Zett. Numerous specimens collected from the 
marshes, late summer and fall. These seem to have the 
bands of the abdomen broader and less undulating than 
nitens, otherwise I can see no differences between the two 
species. 
54. S. ribesii Linn. Pierce, Buffalo, Dane, Manitowoc, Vilas, 
Price, Grant, Milwaukee, Washington, Marathon, Douglas, 
and Burnett Counties. Throughout the season. I have a 
complete series ranging from 6 to 14 mm. in length. The 
smallest have the bands going over the sides of the abdo¬ 
men entirely, face all yellow. About half of the larger
