 weakly margined, not punctate; anal scale obtnsely angled. Hepugna- 

 torial j»ores jdacedon anterior division, small and ratherdeej) set. Legs 

 extending slightly beyond sides of body. Male: Slemlerer than fennile; 

 coxa^ of .'Jd, 4th, oth, pairs of legs producid into short lobes; til»ia and 

 first two tarsal Joints beneath witli an oval roughened lobe;.joints of 

 anterior legs short and thick, third and fouith |)airs of legs strongest; 

 tarsi withouta pad; ventral i)lateof copulation-foot triangnlaras high as 

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

 plate of a triangular-pyramidal form; anterior i)art of first foot not as 

 high as ventral i)late, triangularly pointed, the ventral plate ridge 

 separating them; posterior part of anterior foot as high as ventral 

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

 copulation-foot bitid, projecting out of tlu' opening, the upper braindies 

 flattened and fan-sh.aped at its end, which is convex; h>wer branch 

 elongate-lanceolate, its upper e«lge serrate, basal i)art of foot rectang- 

 ular and white, while the ujjper ])art is yellowish. Segnu'nts male, 4<5; 

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



This species is described from six broken and badly preserved si)eci- 

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

 dugeai^ and it is very ])robable that all the species behmging to this 

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

 as ])osterior part of anterior ])art, while the anterior part is less, the 

 posterior foot bitid and projecting out of the oitening. 



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

 emy of Xatural Sciences of Philadelphia, 



2. Jiilus Moreleti I^ucus. 



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

 this species. It has only been found in the Azores Islands. 



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

 ments not so irregular as represented in Porath's figure of this spe- 

 cies.* 



Segments 42-49. Adult almost black, legs reddish brown; young 

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

 line, bordered with yellowish,
