from 15 to 17 segments in the male and ii to 17 in the female ; 

 while in the latter they are very indistinctly segmented, except 

 the first and second segments, and are composed of but seven 

 segments in either sex, the segments beyond the second often 

 so closely connate as to form a single inarticulate club. 



A free translation of Pantel's Latin description of the 

 antennae of Leptynia is as follows : 



" Male. — Antennae about one-third as long as the anterior 

 femora, heterogeneous, the second segment no less transverse 

 than in Bacillus. The rest of the segments up to the middle 

 of the antennae notably elongate, the following ones abbrevi- 

 ated. Near the apex, each segment is distinctly transverse. 

 The apical segment either longer than the three preceding 

 ones or of equal length with them. 



" Female. — Antennae short, heterogeneous, segments one, 

 three and five and the apical ones much longer than wide, the 

 rest notably transverse ; the apical segment at least equal to 

 the four preceding ones." 



In Parabacillus the antennae are variable in length, but usu- 

 ally about the same as in Leptynia, apparently composed of 

 seven segments, though those beyond the second are more or 

 less coalesced, often altogether invisibly joined, forming a 

 single club. In the more distinctly segmented specimens the 

 various segments may be comparatively described as follows : 



Male. — First segment large, much broader than the rest, 

 about four times longer than wide, flattened, keeled above; 

 2, distinct, transverse, one-fourth as long as i; 3, 4, 5 and 6 

 subequal in length, each as long or a little longer than i and 2 

 together; 7, nearl}^ twice as long as the preceding one, con- 

 cave on the inner side and sometimes showing very slight 

 indication of being composed of two segments. 



Female. — In general, the antennae are similar to those of 

 the male, but are usually comparatively shorter. Segments i 

 and 2 as in the male ; 3, equal to i and 2 in length ; 4, one- 

 half as long as 3 ; 5 and 6 subequal, each about two-thirds as 

 long as 3 ; 7, variable, sometimes twice as long as the preced- 

 ing one and sometimes about equalling it in length. The 

 segments of both sexes are very varia])le in comparative
