[October 
Spilogona Schnabl. 
Spilogona will supplant Melanoclielia Rondani as the generic 
name for the group dealt with under the last name in my paper 
in Canadian Entomologist, pages 61-64, 1921. 
Spilogona argenticeps sp. nov.

white dusted, the two latter almost tomentose and silvery, back 
of head pale gray pruinescent. Thorax pale gray pruinescent, 
with three very faint dark vittse; scutellum darker, more shin- 
ing, and when seen from in front with the sides darker than the 
disc. Abdomen whitish gray pruinescent, first tergite largely 
black on disc, the next three each with a pair of large sub- 
triangular black spots which extend almost the entire length 
of tergites and are distinctly separated in middle. Legs pitchy 
colored. Wings slightly grayish, veins brown, whitish at bases. 
Clyptrae white. Hal teres yellowish white. 
Frons a little less than one third of the head width, orbits 
not strikingly differentiated, narrowed posteriorally ; ocellar
