 1896. Papirius testudineatus Folsom. 



Prevailing color, dark purple, almost black with conspicuous 

 wax yellow patterns. Head large, face with large markings and 

 a few short bristles; vertex with a few long bristles, and a stir- 

 rup shaped marking in the middle; behind this a long, broken, 

 transverse band. Antennae, .7 the length of body, purplish; 

 basal segment' twice as thick as second; second five times as long 

 as first, somewhat petiolate with a few hairs; third equalling 

 first two, slightly petiolate, gradually forming sub-segments dis- 

 tally, the first seven of which are distinct, and the three distal 

 ones much swollen, especially the penultimate one; terminal 

 segment equal to basal in length ; third and fourth segments with 

 whorls of long hair. Eyes black. Body, abdomen ovate dor- 

 sally, with a large pattern composed principally of thick median, 

 longitudional and oblique bars ; dorsum with a few long bristles 

 anteriorly-, many short ones posteriorly ; sides with large, elongate 

 spots; anal tubercle large, with several large spots, and many stiff 

 bristles. Legs very long, slender, hairy, with broad, alternate 

 bands of purple and yellow, except on the tibia. Superior claw 

 long, of rather uniform width, bent only towards the tip, divided 

 on the inside nearly into thirds by two prominent teeth ; inferior 

 claw half as long, conical in shape, apparently prolonged into a 

 bristle; a short bristle on inside of inferior claw at its base. 

 Furcula long, nearly reaching mouth, purplish; each dentes 

 with a row of long spines on either side; mucrones white, cylin- 

 drical ; apex rounded, one-third the length of dentes, serrated 

 beneath. Length 2.2 mm. 



The description was taken from four specimens which were

 sagittal mark from antennae to pro-thorax; black ocelli-like 

 effect on the middle of the vertex; a few short bristles upon the

 individuals; segments variable in relative length, but approxi- 

 mately in the ratio of 1:6:7:1. .5, or 1:7:9:2; basal segment short, 

 as long as broad, brownish with short white bristles, the remain-
