212 CAMPODEA. 



This interesting family contains two genera, 

 Nicoletia, Gervais, and Gmnpodea, Westwood. The 

 former is most nearly allied to the Lepismadce, having 

 three caudal appendages and large palpi. Indeed, the 

 structure of the mouth in Nicoletia is very different 

 from that in Gamjjodea. Unfortunately, however, 

 Gervais gives no detailed description, and I have had 

 no opportunity of myself examining either species of 

 the genus. From Gervais' figure and Nicolet's de- 

 scription^ the mandibles and maxillae seem to be much 

 less retracted than in Nicoletia; the maxillary palpi 

 are elongate and 5-jointed ; the labial palpi 4-jointed, 

 If there is no mistake about these facts it will scarcely 

 be possible to retain Gmnpodea and Nicoletia in the 

 same family, but I cannot help still feeling some doubt 

 whether Nicoletia is a mature form ; Gami^odea, as 

 already mentioned, seems to me to be the representa- 

 tion of a form from which many other groups have 

 been derived.
