from the three regions mentioned on the basis of any characters 

 thus far pointed out. I cannot speak with confidence as to 

 coloration as it may be present in the living animals. Certainly 

 there can be no separation on the basis of the characters to 

 which Verhoeff gives primary importance in his study of the 

 genus in Europe,* such as the number and arrangement of the 

 spinules on the fifth, sixth and seventh tergites, the number 

 of articles in the first division of the antennae {fiagelliim primiim), 

 the number of divisions in first and second tarsi and the number 

 and arrangement of the "pegs" on the latter, and the number 

 and arrangement of spinules on the several joints of the legs. 

 In fact, the variation in these characters in such, often on the 

 two sides of the same animal, that one cannot help feeling 

 skeptical as to the validity of the species and subspecies estab- 

 lished by Verhoeff in the place mentioned, since the characters 

 are used in the key with rather narrow limits, and the material 

 studied by him was not extensive. 



The tabulations which follow are constructed to represent 

 the variations found in the characters mentioned in several 

 individuals from the Bermudas and from the United States in 

 comparison with a standard one from Toulouse, France, sent 

 me through the kindness of Dr. Brolemann. In the first table 

 the plus sign in the first two columns in the case of each tergite 

 is used to separate the number on the left side from that on the 

 right. In the third column is given only the general total of 

 spinules for the surface, exclusive of margins and saddle. In 

 the second table, showing the number of articles in the first 

 division of the antennae and in the first and second tarsi, the 

 plus sign is used to separate the number of articles in the first 

 tarsus (always given first) from the number in the second. In 

 the subsequent tabulations, giving the spinules of the legs, the 

 plus sign where appearing under femur and tibia is used to 

 separate the number of spines at the distal margin given after 

 the sign, from the number appearing proximad of this in the 

 position indicated. Under tarsus I the sign separates the num- 

 ber of spinules appearing on successive articles beginning with 

 the first. Under tarsus II the numbers given represent the 

 number of segments, counting from the most proximal, upon 

 which pegs appear. Where in this column a dash appears, it
