The North American Species of Chariessa (Coleoptera). 
By A. B. Woxcorr, Chicago, Il. 
Three examples of an undescribed species of the genus 
Chariessa have been in my collection for many years. Speci- 
mens of the four species and one color variety known to occur 
in our fauna are now before me, and demonstrate that the 
nondescript is specifically distinct. : 
Our few species may be separated by the aid of the follow- 
ing table : 
A. Abdomen entirely red. 
b. Thorax depressed, sides narrowing anteriorly, pubescence of thorax 
light red ; elytra broadly dilated posteriorly. Length 7-14mm.

In this beautiful species, which has erroneously been accred- 
ited to Spinola, the elytra and prothorax are blue, densely 
pubescent with erect whitish hairs, on each elytron before the 
middle there is a large transversely oval, velvety black spot ;
