128 CHAS. K. BRAIN. 



become too generally chitinised there is an indication of a small third lobe immediately 

 anterior to the second incision. Later, when the surrounding chitin is denser, this 

 appears as part of the pygidial margin. L x large + triangular, once notched on 

 the outer side. L 3 similar but less than half the size. P absent. The chitinous 

 thickenings to the first incision are large, unequal, the mesal one being the larger. 

 The thickening to the second incision is large and reniform. Circumgenital and 

 parastigmatic glands 0.

The character of the lobes and the apparent absence of plates places this species 

 very close to A.forbesi, but it is readily separated from this species by the characters 

 of the scale, the median lobes being less convergent and slightly wider apart, the 

 reniform thickenings to the second incisions and the absence of circumgenital glands.

Scale of adult $ strongly convex or almost conical, almost circular to elongate and 

 one-sided, often appearing resinous, yellowish brown, with the exuviae towards one 

 end brownish or blackish. 



Professor Comstock's original description of the $ is as follows : — 



" Female. — The body of the female is nearly circular in outline, bright yellow in 

 color with more or less translucent blotches. The last segment presents the following 

 characters : The group of spinnerets are wanting. 



" Only one pair of well-developed lobes, the median, present. These are prominent. 

 Each one is furnished with a notch on each side, the notch on the mesal margin is 

 distad of that on the lateral margin. The second and third pairs of lobes are repre- 

 sented by the minute pointed projections of the margin of the body. 



" The margin of the ventral surface of the segment is deeply incised twice on each 

 side of the meson ; once laterad of the first lobe, and again between the rudimentary 

 second and third lobes. The parts of the body wall forming the margin of these 

 incisions are conspicuously thickened. 



" There are two simple tapering plates between the median lobes, two deeply and 

 irregularly toothed or branched plates extending caudad of each incision, one usually 

 simple and tapering plate between incisions of each side, and two or three of the same 

 character laterad of the second incision. 



" The first, second, and third pairs of spines of each surface are situated near the 

 lateral bases of the first, second, and third lobes respectively ; the fourth pair are 

 situated at a little more than one-half the distance from the median lobes to the 

 penultimate segment. In each case the spine on the ventral surface is but little 

 laterad of the one on the dorsal surface."
