veins (jf the witiii' in one specimen is nearer tlie enJ of the discal cell, as 

 it is iu Bldcndes; unfortunately in the other specimen it is near the 

 middle, as in T. octopitnctatus. The only characters that I can under- 

 stand for Bldcodf'n now, are : Abdomen smooth, not clavate, thorax a 

 little more uihbose, third joint of antennae perhaps more fusiform,- fourth 

 posterior cell of the winjis nearly elused. and the wings with dark markings.

Three specimens from W^estern Kansas agree throughout witli Dr. 

 Loew's description ; the tip of the second joint of the antennae is dis- 

 tinctly yellowish ; in two specimens the fourth posterior cell is closed a 

 little distance before the border of the wing.

S. adu'^tus Loew 1. c. 'Mb. •' 9 • — Black, head and thorax very thickly luteo- 

 pollinose, the posterior part of each abdominal segment broadly red, the first five 

 on the posterior angles with thick d.ilutely luteseeiit pollen ; antennae and feet red. 

 the femora near the tip black : wings hyaline, the tip broadly blackish. Texas.'" 

 Two female and one male specimens from Western Kansas (E. W. 

 Guild) are midoubtedly this, 'but the species is evidently variable in col- 

 oration, lu all my specimens the legs are wholly reddish yellow, and 

 the antennae of one specimen lacks the black at the tip of the third joint. 

 In two specimens the ground color of the thorax is chiefly black, yellow- 

 ish only on the front, sides and posterior part, in the third, a female, the 

 ground color is wholly light yellowish red, with the rather narrow and 

 abbreviated stripes of the thorax and a small spot above the middle coxae 

 black. In all tlu' abdomen is red, with a large triangular spot on the 

 lateral anterior [larts u\' the third, fourth and fifth segments, .scarcely 

 touching each other on the anterior border, a smaller one more broken 

 up into spots on the second .segment, and a very small mie on the anterior 

 angle of the sixth, black.
