214 NICOLETIA. 



Nicoletia, Grervais. 



" Corpus elongatum, abdomine decemarticulato. 



" AntennaB longge, multiarticulatge. Palpi maxillares 

 elongati, 5-articulati. Palpi labiales 4-articulat8e. 

 Cerci caudales tres, elongat^e." 



Nicolet says tliat tliere are seven very small oval 

 eyes on each side of tlie head, arranged in an obhque 

 Hne, a little behind the antenna. 



Nicolet has named two species of this genus, N. 

 geopliila and i\^. ]^j]iytoijhila. He gives no description 

 of the former in the ' Ins. Apt. ' (vol. iii, p. 454), but 

 refers to the ' Ann. Soc. Ent. France,' vol. xi, p. 48, 

 where he gives a generic character, in which the pecu- 

 liar structure of the mouth is omitted, but no specific 

 characters are given for either species. 



Nicoletia i)liytopliila is described as— 



" Blanc jaunatre. Tete et corps '004 en longueur." 



This genus has not yet been found in England. 



lAPYGIDii. 



" Antennae multiarticulatse. Maxilla Integra, falcata, 

 acuta, in tus pectinata. Palpi breves. Prothorax mini- 

 mus. Unguiculi bini inasquales. Abdomen segmentis 

 10 ; segmentis anterioribus muticis." 



I must confess that I have considerable doubts 

 whether this and the preceding family ought to be 

 classed with Lejnsma and MacJdlis. In many respects 

 they resemble the Collembola, but they do not appear 

 to possess the ventral organ which is so characteristic 

 of that group. Again, the mouth parts of Nicoletia ap- 

 pear to differ greatly from the type of the Collembola, 

 but unfortunately they have not been satisfactorily 

 described, and I have had no opportunity of examining 

 them personally.
