DAMiEUS AUHITUS. 437 



division, between the first and second leg, is a strong 

 chitinous projection, ratlier more marked than that of 

 D. genlcalatiis, having a sharp tooth-like anterior, and 

 a blnnt posterior process. The second leg is articu- 

 lated immediately behind this projection. 



Legs slightly longer in proportion than those of 

 D. geniciilatiis, rather thick for the genus. Coxae of 

 the two hind pairs of legs large, each with a small 

 projecting blade on the posterior lower edge. Femora 

 gradually thicken from the proximal until near the 

 distal ends, the heads being indistinctly marked off from 

 the peduncles but still being a trifle more distinct than in 

 D. geniculatus. Genuals and tibiae slightly enlarged 

 towards the distal ends. Tarsi with pedunculated, 

 more or less diamond-shaped, proximal parts, and rod- 

 like distal portions slightly curved or undulated at the 

 ends. There is a whorl of thick, black, stiff, serrated 

 curved hairs or spines on the ends of each of the three 

 central joints of each leg ; one on the peduncle of each 

 femur of the two front pairs ; two on each coxa of the 

 third, and one on each coxa of the fourth pair. There 

 is a fine but short tactile hair on each tibia and the 

 usual fine hairs on the tarsi. 



Abdomen almost hemispherical or slightly pyriform. 

 Nicolet says that the progaster is truncated and 

 sinuated, which I have not observed in the English 

 specimens ; it stands considerably above the base of the 

 cephalothorax. There is a rather large anterior de- 

 pressed portion at the antero-lateral angle ; the outer 

 edge of this is cut into three blunt teeth, almost undula- 

 tions, between the first and second of which the third leg 

 is articulated, and a small, rounded, posterior lobe to 

 which the fourth leg is articulated . There is an almost 

 elliptical series of about eighteen short, fine, very sharply 

 curved, almost hooked hairs on the notogaster, which in 

 shape are much like the claws, but thinner ; the first 

 pair stand forward, over the cephalothorax, the others 

 are directed backward ; many specimens show a slight 

 indication of a ridge on the abdomen outside the line
