the adult, but the feet are more slender. The margin bears a row of 

 very fine spiny hairs, and four spiracular groups of large conical spines. 

 There are many small circular spinnerets on the epidermis. 



Larva yellow, elliptical, flattish; length about T V of an inch. Form 

 normally lecanid, the anal lobes bearing long setae. Antennae thick, 

 with six rather confused joints. 



Male unknown. 



On camellia. (In greenhouse.) 



I have often met with this scale on many plants from Japan at the 

 quarantine station in San Francisco. Judging from the number found 

 infested it must be plentiful in that country. The camellia on which I 

 found it in California was in a Japanese nursery, and was promptly 

 destroyed. 



Eucalymanatus perforates News. 



Adult female. Irregularly oval, bluntly acuminate in front, broadly 

 rounded behind; sometimes almost dull colored; usually asymmetrical; 

 flattish; median area very slightly convex, margins very thin. Under 



surface flat; a small hollow on 

 each side of abdomen. Color 

 dark castaneous, paling to 

 fulvous or greenish yellow at 

 margin. Dorsal area divided 

 into numerous irregular

marqueterie pattern, more 



conspicuous after treatment to potash. The pattern is roughly but 

 not absolutely symmetrical on the two sides of a median line. The 

 number of separate tesserae vary slightly in different individuals by 

 the confluence of adjoining plate, but the main plan is constant, viz., 

 four series on each side of the median line, indicated on the surface 

 by a series of depressed, irregularly polygonal spaces, divided by slight 

 carinae. Dermal cells numerous but ill-defined, irregularly oval, groups 

 of them often forming irregular rosettes; but there is also near the 

 margin of each plate, more particularly on those of the median series, 

 a series of minute translucent pores, bearing a fanciful resemblance to 

 rivet holes for the attachment of armor plates. Eyes minute, black, 

 marginal. Marginal hairs small, simple. Submarginal tubercles five 

 to seven on each side. Stigmatic clefts with three (rarely four) stout 

 spines, the median one longest and projecting beyond the margin 

 Anal cleft rather more than one quarter the total length of the insect 

 Scales of anal operculum together forming a square, their extremities 

 rather acutely pointed. Anal ring with six hairs; two or three stout
