Extract

Dactylopius Irishi, sp. n.

♀.—Adult dark red, forming a very convex chalk-white ovisac about 3 millim, long and 2½ high, the sacs clustered on the twigs of the plant at the nodes, from two to ten at a node. Eggs and newly-hatched larvæ pale yellow.

Adult ♀, after being boiled and flattened on a slide, nearly circular, about 2 mm. long. The insects do not stain the liquor potassæ on boiling, but the body contains a dull crimson pigment, partly retained in boiled specimens.
