surface of metazonites strongly tuberculate, the tubercles in 

 irregular in part confined transverse series, of which there 

 are usually about four caudad of the transverse sulcus, which 

 is distinct, and six in front of it, the tubercles in general 

 smaller toward the anterior and posterior margins, the tuber- 

 cles extending out upon the keels, but just within the margin 

 of latter fewer and more weakly developed. All tubercles 

 setigerous. (PI. 22, Figs. 154. 155.) 



Sternites of fifth and sixth segments in the male each with 

 a pair of low and broad, distally rounded, large tubercles 

 between first pair of legs. 



In the male metatarsal pads projecting distad between the 

 tarsi are developed on the first seven pairs of legs. In the 

 seventh legs of the male the femur is much thickened, widest 

 distad, and is strongly bent, its base projecting as a prominent 

 lobe, as shown in PI. 22, Fig. 156.
