Eyes longitudinal, placed oppo- 

 site the base of the superior an- 

 tennas. 



Eyes small, longitudinal, placed 

 opposite the base of the superior or 

 inferior antennse. 



The sujyerior antennce are short- 

 er than the inferior, abbreviated, 

 compressed, triarticulate ; the basal 

 joints short, robust, concealed by 

 the clypeus; terminal joints not ar- 

 ticulated, linear, compressed, ob- 

 tuse. 



[Here is a slight difFerence, but it may be considered 

 only a difference between species, and tliis tlie more as among 

 my new species I liave two totally blind ones]. 



The superior antenntB are short- 

 er than the inferior, compressed; 

 the peduncle triarticulate; the basal 

 joints robust, the first concealed by 

 the front, the second and third very 

 short. The flagellum consists of a 

 compressed obtuse large basal joint 

 and 3 — 4 very minute terminal ones. 

 [The want of coincidence with respect to the niimber of 

 the joints of the superior antennse between Sats description 

 and mine is not difficult to explain, if we remember that Milne- 

 Edwaeds, Dana, Spence Bate and others made the same mis- 

 take in interpretiug a very similar organ: the superior antenna 

 of Vibilia. This was stated by all of them to be triarticulate, 

 consisting of a two-articulated peduncle and a large compressed 

 lanceolate flagellum, whereas in fact the case is herc the 

 same as in Lanceola: the short peduncle is three-jointed and 

 the large basal joiut of the flagellum carries at the end 2 — 4 

 very minute artides, smaller in the adult animal than in the 

 young one. The small terminal artides in Lanceola require 

 in order to be seen a higher magnifying power than was probably 

 used by Sat, and the last of the peduncular joints is very 

 often concealed by the preceding one. Such being the case, 

 I think the characters of the upper antenna? are no obstacles 

 to the identity]. 



Inferior antennas very long, 

 four-jointed, compressed; basal joints 

 very short, third and fourth longer, 

 equal, the latter entire. 



Mouth protuberant. 



Labrum emarginate, supporting 

 two filiform triarticulate processes, 

 of which the first joint is very short, 

 second linear, third shorter, subulate. 



Pedipalpi bifid, laciniae linear, 

 inner edge hirsute, tips rounded. 



Inferior antennse very long, 

 four-jointed, compressed; basal joints 

 very short, third and fourth longer, 

 equal. 



Mouth protuberant. 



Mandibles strong, without molar 

 tubercle, with filiform triarticulate 

 palp, of which the first joint is very 

 short, the second the longest, linear, 

 the third shorter, subulate. 



Maxillipeds consisting of a 

 strong peduncle and two broad 

 linear laminffi, inner edges hirsute, 

 tips rounded.
