Ventral side. The sternalhairs cannothave been correctly 

 delineated by Berlese, as their arrangement does not agrée 

 with that of my spécimens ; and this feature, the arrangement 

 of the sternal and metasternal hairs, is, as far as we know, 

 never subjected to any variation. Berlese only draws 3 pairs 

 of hairs, which is obviously not in accordance with the facts, 

 since there are always 4 pairs of them. 



It is évident that B. has overlooked the anterior pair, which 

 is placed at the anterior margin of the sternal shield. B's ante- 

 rior pair is in reaUty the second one, inserted on a level behind 

 the middle of coxae II. The next pair is correctly placed by 

 B., viz. on a level between coxae II and III, but the posterior 

 pair is placed at the posterior margin of the sternal shield, 

 whereas in reahty it is inserted farther back, in the angle bet- 

 ween coxae III and IV, exactly as in H. miles Berl., where it is 

 correctly dehneated. It is not surrounded by any small plates as 

 is the case in Holostaspis, Eviphis, and others, for instance. 



The epigynial shield bears one pan- of hairs, inserted at 

 the very margin, on a level with the posterior side of coxae IV. 



The stigmata (fig. 95) and base of the peritremata are 

 surrounded by a narro w peritrematicshield, whose portion 

 behind the stigmata is three times as long as the portion in 

 front of it. It tapers gradually backwards, with even médian, 

 wavy latéral margin, and is obliquely truncated at the top. 



Legs. Legs II (fîg. 06) thick, with fémur, genu and tibia 

 of subequal length, but decreasing successively in width. 

 Tarsus a little more than half as wide as tibia, with distinc- 

 tly demarcated basitarsus. On fémur, one stout, perpendicular 

 bristle, ventrally, in the middle ; on genu, one smaller one, 

 ventrally, in front of the middle ; on tibia two bristles, as 

 large as the fémoral one, in a transversal row near the anterior 

 margin, ventrally. Tarsus with two slightly curved, stout 

 bristles at the top ; two dorsally, near the top ; and two, one 

 behind the other, ventrally. 



Legs III with two similar bristles ventrally, in a trans-
