Capulinia crateraformis, n. sp.
The ♀ makes a small crater-shaped gall in the bark of the limbs and twigs. This gall is about 1.5 mm. high, and consists of an outer circular ring from 1 mm. to 1.5 mm. in diameter, and a small cone within, which can readily be removed. The cavity inhabited by the insect is smooth and is lined with a white powder. The adult ♀ is small, oval in outline, pink, and is dusted with a white powdery secretion. Boiled in a solution of KOH it becomes colourless. Size, after boiling: length, .96 mm.; width, .73 mm.
