described by them is a species of Pristoceuthophilus. A photograph 

 of this specimen was kindly sent the writer some years ago by the 

 director of the Musee d'Histoire Naturelle of Geneva and an outhne 

 drawing made from this photograph is here reproduced (fig. 27).

This photograph, considerably enlarged though it is, fails to show 

 sufiicient details to enable the correct placing of the species. K, 

 upon examination of the specimen, this insect proves distinct from 

 any described form, a new name will be necessary for it. 



Together with the above-mentioned photograph was received one 

 of the second United States species, H. platyceps Saussure and Pictet. 



An outline drawing of the hind tabia and tarsus made from this 

 photograph is also here reproduced (fig. 28).

CNEMOTETTIX, new genus. 



The material upon which this genus is based was found in a neg- 

 lected lot of alcoholic specimens after the page proof of this article was 

 received and only a brief discussion of its characters can therefore be 

 inserted. The vertex is entire and the legs short, the hind femora 

 scarcely as long as the body, but the most important characters lie 

 in the tibiae and tarsi. The tarsi have more or less well-developed 

 pulvilU beneath, double on the metatarsus, the fore tibiae are with-

 of stout elongate-triangular inarticulate spurs of which about every 

 alternate one is approximately twice as large as the others, the
