12 SCALE-INSECTS 



It is a brown, or reddish-brown scale, hemispherical in form, hard 

 in texture, and varies from 3 to 5 mm. in breadth and 4 to (> 

 mm. in length. Some of them are very dark brown in color. Be- 

 neath this scale, as in the preceding species, is to be found either the 

 soft insect or the eggs. The species has not been described, and I 

 will not attempt to give other than the above brief description here. 

 Professor Riley, who has seen specimens, has furnished the above 

 manuscript name to be used in referring to the species. The short 

 description and the food-plant will doubtless enable its recognition. 



Egg. The eggs are pale reddish-pink in color, very small, 

 and a great many are to be found under one scale. They were ob- 

 served to be hatching May 22. 



Food-plants. This scale has been found here only on im- 

 ported trees of black locust (Rob In id jwinldcdcid), the branches 

 and twigs of which it very plentifully infests. It is more or less 

 unnoticeable on account of its color being much the same as that 

 of the twigs upon which it occurs. 



Parasites. No true parasites have been observed. A locust 

 tree which was infested with the scale was found to be well stocked 

 with the California Cooclnella oculata, and its ashy gray variety 

 (C. abdominalis). These undoubtedly prey upon this and other 

 scales. The variety seemed to predominate, and though all stages 

 from eggs to adults were to be found May 22, the pupae were by 

 far the most abundant. 



NO. VI. 



SOFT PEACH SCALE (LcCfllUHIK Sp.). 



A single specimen of a soft, brownish, more or less hemispher- 

 ical scale-insect, about 5 mm. in length, was found April 11, 011 a 

 branch of the peach. No others were found, and it is simply men- 

 tioned here so it may be looked for by fruit-growers. We shall 

 be glad to receive any specimens of it that may be found. Unlike 

 all the preceding species, it is simply the bare, soft insect that must 

 be looked for, as it apparently does not cover itself with a scale.
