'In the November 8, 1884, number of El] Progreso de Mexico there is a long article 
by Dr. Jose C. Segura on the coffee scale, there identified as Dactylopius destructor 
(=D. citri). The localities given are Orizaba, Cordova, Uruapan, Ario, Cuicatlan, 
Jacona, Tacambaro, and doubtfully Coatepec (near Jalapa). It is said to be worse 
in the cafetals of Orizaba and Uruapan.—C., H. T, T.
