Around the margins of the body is quite a wide colorless band extending half-way 

 from the margin to the light median line on the dorsum. The general back- 

 groimd color is a gray. The bodies are rather long, and may be so thick on the 

 branches as to overlap so as to completely hide the surface of the branch. The 

 antennae are /-articled and small, as are also the legs. 



The scale multiplies with wonderful rapidity, and so far as our examination 

 goes, they are nearly free from parasites. They attack principally the younger 

 shoots. Soft Brown Scale seems to limit its attacks by preference to the young 

 trees, but this scale works as successfully on the old trees as on the young, but 

 generally on the new growth. So far, it has been reported in only two orchards 

 in any considerable numbers. Due to the fact that it is an unarmored scale, and 

 so soft, it will probably not require any special fumigation dosage to rid the 

 orchards of it. An ordinary Black-Scale dosage will do the work.- But because 

 of its ability to increase in such enormous numbers, care must be taken to rid the 

 orchards of it before a great deal of damage has been done. Like most imported 

 scales it has probably been struggling under changed climatic conditions, and is 

 just beginning to thrive.

The female scale is irregularly elongated about 1 mm. in length, gray with 

 darker marginal exuviae. The female body has three pairs of well-developed anal 

 lobes (Figure 19), and a less developed fourth lobe resembling a papilla. Be- 

 tween the lobes and extending along the lateral margins are numerous hairs which 

 arise from well-defined lateral lobes. There are four groups of circumgenital 

 pores, the two upper groups usually having six, the two groups near cauda having 

 seven. The whole body shows the segmentation very plainly.
