SCOLOPENDRA. 13 
Order SCOLOPENDROMORPHA, nov. 
[ = Scolopendride of authors. | 
Fam. SCOLOPENDRIDSA (sensu stricto). 
Body composed of 21 leg-bearing segments. Head furnished on each side with 4 
distinct ocelli. Legs with the tarsal segments two-jointed. 
This family may be divided into two subfamilies—the Alipedine for the S.-African 
genus Alipes, which has the distal segments of the anal legs enormously expanded and 
flattened, and no claw on the tarsus; and the Scolopendrine, in which the anal legs 
are normally constructed. 
Subfam. SCOLOPENDRINA, Newp. 
Excepting for the elimination of Alipes (Eucorybas), I use this subfamily in the 
same sense as that employed by Bollman (Bull. U.S. Mus. 1893, p. 165). It includes 
the Cormocephaline and Heterostomine (=Rhysidine, Silvestri, 1895) of Newport.
