mottlings of lighter color, the light spots irregular in form and separated from one 

 another by lines of a darker tint. 



Front leg. — The coxa has two apical bristles and one basal one. Trochanter with 

 one apical bristle; the femur is slightly longer than the tibia, and the tarsus about 

 two-thirds the length of the tibia.

Fig. 3. — Apricot Scale Lecanium armeniacum. Female, a. Antenna; b. anal plates and ano- 

 genital ring ; c, front leg ; d, spines on lateral margin greatly enlarged. Original. 



Antenna. — These are seven jointed; joints 3 and 4 about equal; 3 slightly longer than 

 7; 1 about equal to 2; and 5 and 6 short and subequal, together about as long as 7. 

 In studying a long series of specimens, it was found that no exact formula would 

 hold good throughout the series. Sometimes, as in the case of all Lecaniums, the 

 antenna on one side would not correspond with the one opposite. Sometimes joints 

 3 and 4 would be connate, and sometimes they were so on one side and not on the 

 other. Sometimes the proportions of 5 and G would not hold true but there is a 

 certain type to which most individuals conform and from which few depart very far. 

 The specimen figured represents this type as well as any that was seen. The ano- 

 genital ring has eight internal hairs. The anal scales are triangular with four apical 

 short hairs. 



ITS NAME. 



The name of this interesting species was for some time a question to the writer. 

 Among the species to which it might have been referred were juglandis Bouche. 

 juglandifex Fitch, which is probably a synonym of juglandis, cerasifex Fitch, rugosum 

 Sign, prunastri Fonsc, and rotundum Reaumur. Specimens of the New York plum 

 scale, Lecanium cerasifex. from Geneva, X. Y., were kindly sent me by Mr. V. H. Lowe. 

 Entomologist of the N. Y. State Experiment Station at Geneva, and others were sent 

 from Oswego, N. Y., by Prof. M. V. Slingerland, Entomologist of the Cornell Experiment 

 station at Ithaca, N. Y. Prof. Slingerland also sent me specimens from the worst 

 infected orchard in the infestation of 1894. Specimens of L. cerasifex determined by 

 Mr. Pergande were also kindly sent me by Dr. L. 0. Howard, Entomologist of the U. S. 

 Department of Agriculture, and in my collection are specimens of L. armeniacum from 

 California from Mr. Ehrhorn, which are undoubtedly correctly determined.
