like Adalia bipunctata Linn. The head is l^lack with one white 

 si)ot near each eye, the clypeus, especially in the male, is often 

 more or less white. The prothorax is black with a large white 

 spot on each side of the anterior angles. The elytra, yellowish 

 red, distinctly punctate, with a somewhat inverted heart-shaped 

 scutellar spot and four spots on each elytron, one at humeral 

 umbone, two slightly above middle placed in an oblique line and 

 two slightly below middle. The var. menetriesi Muls., which 

 may occur in our Northwestern territory, differs from the typical 

 form in having the lateral margin of prothorax from apex to base 

 and also the anterior margin narrowlv white.
