 EuscMstus tristigma, Dallas, I, c. i, 207, No. 18. 



Inhabits Texas, Indian Territory, Kansas, Missouri, and from Florida 

 to New York. Those with blunt lateral angles have been obtained in 

 Washington Territory, Kansas, Canada, New England, Pennsylvania, 

 Maryland, Iowa, and New York. It sometimes occurs in large numbers, 

 in late summer, on bushes in damp situations. No species thus- far dis- 

 covered in this country exhibits such a wide range of differences in the 

 form of the pronotum. The form most common in Maryland has acute 

 and acuminate lateral angles, but longer than in others from Pennsylva- 

 nia, Virginia, Louisiana, and some other parts of the South. The large 

 specimens, with bluntly-rounded angles, have not yet been collected by 

 me in company with the other form. A whitish bloom often covers the 

 mature specimens in this region.
