Recently I received from Mr. J. Sperry a srnall series of a Thraulodes species from Arizona which, while apparently very closely allied to speciosus Trav. in genitalia, as far as can be told from the rather crude figure (Biol. of Mayflies, 553, fig. 146), does not fit in with Traver's description in several points. I am treating it therefore as undescribed.

Within the past few years, two species of mealybugs have become serious pests of apple in North America. In Virginia, for some apparently unknown reason, the Japanese Comstock mealybug. Pseudococcus comstocki Kuwana, has undergone a change in its feeding habits and produced a strain that has become well adapted to feeding and reproducing on apple.

Two subspecies of Agabus seriatus (Say) are recognized, A. s. seriatus from Manitoba eastward and southward, and A. s. intersectus (Crotch) from Manitoba west to British Columbia and south to New Mexico. A. pandurus, allied to brevicollis Leconte, and A. vandykei, allied to verisimilis Brown, are described from California.
