hunter: the COCCIDA''. of KANSAS. 3 



The microscope used is the C. Zeiss, Jena, stand la, with complete 

 equipment. The objectives used on triple nose piece are low 

 power B, high power F, and oil immersion 1-12 inch, N. A. 1.22. 

 Though I have tried an Abbe camera lucida, I prefer to make the 

 sketches free hand. 

 Aspidiotus forbesi Johns. Plate I, Figs, i, 2, 3, 4, 5; Plate II, Figs. 6, 7, 



The scales of male and female in this group, brought together 

 from widely separated localities, conform to the description. 



Lots A, B, C, F and E show distinct tendency to congregate in 

 groups and then others mass upon these. Lot G, though on old 

 cherry trees, were few in number and only to be found upon one 

 or two spots in three adjacent cherry trees. Lot F was most 

 abundant upon the oki bark of the trunk of the apple tree. Bark 

 of apple tree frequently pitted. Lots D and E appeared to be dis- 

 tributed more nearly over the bark. Of this group the following 

 numbers of mounts of each have been studied: eight, of A; ten, of 

 B; nine, of C; four, of G; ten, of D; seven, of E; four, of F; 

 making in all fifty-two individuals, these agree with "Plates in- 

 conspicuous or absent, spines prominent," but differ uniformly 

 in number of spines. 



There is in each lot, spine on median lobe agreeing with des- 

 cription, /'/// a/io/IuT spiiu- appears extending over the margin from the 

 dorsal side, one beside the "second" and one beside the "third" 

 spine, making a pair of spines, one on the ventral and one on the 

 dorsal side, instead of one spine at "second" and "third." This 

 was so in all cases and in this respect they agree with aneyelus. 

 The chitine at the incisions appears to be uniformly heavier than 

 shown in the original sketch. Lot D presents the greatest variations, 

 as shown by sketches. Another form, which is very suggestive of 

 another species, appears on same branch among this lot D. More 

 material will be required before this point can be satisfactorily de- 

 termined. The second lobe is notched, agreeing with Professor 

 Cockerell's observation, but the larger chitinous process between 

 rirst and second lobe is less twisted than shown by the same author. 

 (Tech. Ser. No. 6, Div. Ent., pp. 6 and 8.) The scale is found 

 upon trunk and branches. More abundant upon heavier limbs. 1 

 have found it upon the twigs and in and around the terminal buds 

 of twigs.* 



*:?ince tilt" above \v;is written I have found tliis scale upon cherry and apple in Ao- 

 deison county and upon clierry and apple in Franktlu county. In Franklin county a 

 plot of five acres of apple stock beinj^ cultivated for scions, was so generally infested 

 t)y this scale that it was deemed advisable to uproot the whole plant. A large cherry 

 tree near by was also coiuhMinu'd. 'J'he scions cut this fall from the apple plot will be 

 subjectetl to gas treatment Ijefore being used. 



Farhcsi was first reported from Kansas by Prof. E A. I'openoe in Kansas Farmer. 

 locality not given, reference to which is made in my Bull. Dept. Ent. Univ. Kaii> , 

 Scale limits Injurious to Orchards, p 'Zi, Jan.. 1898.
