 Pedes sat longi, tarsis, saltern ultiuiis binis, articulatis. 

 Antennae 17-30 articulatae. 

 Oculi nulli vel ocellis paucis.

The number of the joints of the antennae is seldom more than 

 22 or 23 ; yet in some true Scolopendrae, as in Se. heros, I have 

 found a greater number, and thus I have been compelled to place 

 the limit as high as 30 joints. 



As a rule, the second and the third joint of the raptorial legs 

 (pedes prensorii) are very small. Furthermore, regularly the 

 rings of these joints are not whole but interrupted at their dor- 

 sal or outermost side ; yet, in the genus Cryptops the ring of 

 the third joint is whole, and thus in this genus the dorsal side 

 of the first and of the fourth joint of the raptorial legs is not as 

 in the other genera united or confined. 



Gervais, in his tables of the genera of the Scolopendrini, 1. c, 

 p. 243, proposes a genus Monops, and in the description of the 

 Cryptops nigra, 1. c, p. 294, he retains this name, but without 

 giving a real description of the genus he only indicates that a 

 pair of eyes is found by him. Now it would be of great interest 

 to have a more full investigation of this new genus ; I do not 

 dare to say that the eyes are wanting, but on the other hand the 

 family Scolopendrini forms such a compact and distinct group 

 of animals, either wanting eyes, or having ihem to the number 

 of four pairs, that it is not likely that in this family one species 

 alone would have one pair ; and, therefore, I believe that the 

 genus Monops must be in many other characters different from 

 the genus Cryptops, if the eyes in reality exist. 



In the lately published genus Plutonium* the number of spi- 



» Cavanna, Bull. Soc. Ent. Hal., xiii, p. 10(1, If. tab. 1. I have nut seen this 

 paper, but, according to Bertkau, the genus seems to relate to Opisthemega.
