OMISSIONS AND 'CORRECTIONS. 203 



smooth, sulcus shallow: clypeus only moderately emarginate, foveolre 

 li+2, distant, sulcus sub-continuous with vertical. Antennae rather 

 slender, reaching second segment in both sexes. Ocelli arranged in a 

 suboval or subtriangular patch, 45-55, in seven or eight series. Seg- 

 ments not smooth; posterior parts above with short and wavy, beneath 

 with short and straight striae; median part with a transverse sulcus 

 which ends above repugnatorial pore; posteriorly above with a lew 

 striae, beneath almost smooth or with a lew weak oblique striae. Lateral 

 lobes of first segment rounded, a weak marginal sulcus. Anal segment 

 with a flat, thick mucro, which passes beyond valves; anal valves 

 weakly margined, not punctate; anal scale obtusely angled, llepugna- 

 torial pores placed on anterior division, small and rather deep set. Legs 

 extending slightly beyond sides of body. Male: Slenderer than female; 

 coxai of 3d, 4th, 5th, pairs of legs produced into short lobes; tibia and 

 lirst two tarsal joints beneath with an oval roughened lobe; joints of 

 anterior legs short and thick, third and fourth pairs of legs strongest; 

 tarsi without a pad; ventral plate of copulation-foot triangular as high as 

 foot, its base not concave, its posterior surface ridged, thus making the 

 plate of a triangular-pyramidal form; anterior part of first foot not as 

 high as ventral plate, triangularly pointed, the ventral plate ridge 

 separating them; posterior part of ^interior foot as high as ventral 

 plate, its apex with a short blunt lobe on its posterior surface; posterior 

 copulation-foot bind, projecting out of the opening, the upper branches 

 flattened and fan shaped at its end, which is convex; lower branch 

 elongate-lanceolate, its upper edge serrate, basal part of foot rectang- 

 ular and white, while the upper part is yellowish. Segments male, 4<i; 

 female, 44. Length 52 """, width 3. 8 """-4. 2 '""'. 



This species is described from six broken and badly preserved speci- 

 mens. In the type of copulation-foot it resembles that of arboreus and 

 f/f^/f.s/, and it is very probable that all the species belonging to this 

 group have the same type, i. e., the ventral plate triangular and as high 

 as posterior part of anterior part, while the anterior part is less, the 

 posterior foot bind and projecting out of the opening. 



1 have named this species after Prof. Angelo Ileilprin, of the Acad- 

 emy of Natural Sciences of Philadelphia. 



2. Juhis Moreleti Luriis. 



In the collection are a number of female specimens which 1 refer to 

 this species. It has only been found in the A/ores Islands. 



These specimens have the stria- of the anterior division of the seg 

 nients not so irregular as represented in PoratlTs figure of this spe- 

 cies.* 



Segments 42-40. Adult almost black, legs reddish brown; young 

 dusky, with a lateral row of black spots and a medium black dorsal 

 line, bordered with yellowish.
