SCOLOPENDRA. 21 
Colour of tergites olive-green or olive-brown ; legs and antenne pale olive-green, or ochraceous ; head and 
maxillipedes more or less castaneous. 
Head punctulate, with two fine strie. 
Antenne with 23 or 24 segments, of which the basal 6 are naked; coxal plates of maxillipedes with the 
three internal teeth confluent. 
Terga not distinctly sulcate, and, excepting the anal, with unraised margins ; the anal without a median stria. 
Sterna strongly bisulcate. 
Anal pleure densely and finely punctulate; the process shortish, tipped with from two to four acute spines. 
Anal legs longish, about three times as long as the head-plate, or rather more; claw spurred ; tarsus unspined ; 
femur armed with from six to eight strong sharp spines, not counting the process, which is robust and 
armed with two acute spines, the spines are disposed as follows: 2 or 3 in two rows on the upper-inner 
edge, 1 or 0 on the under-inner edge, and 4 or 3 in two rows on the under-outer edge. 
Legs with spurred tarsi. 
Length up to 140 millim. 
Hab. Mexico, Vera Cruz !?3 (Saussure); British Honpuras (Mus. Brit., ex Colonial 
Exhibition) ; GuateMa.a, Tucuru in Vera Paz, Livingston (Stol0). 
This species resembles S. heros in size, but may be at once recognized by the unraised 
margins of its terga, the absence of sulci on these plates, and the smaller number and 
larger size of the spines on the anal legs. 
De Saussure’s description does not point out these distinctive characters, and it is 
suggested that S. swmichrastt may be based upon old examples of S. mysteca. But if 
S. mysteca be S. heros, as I suppose, de Saussure’s conclusion will not hold, for Texan 
specimens of S. heros measuring 140 millim. do not resemble S. sumichrasti.

The identity of the species that I have here called S. viridis, Say, is still, in my 
opinion, involved in much obscurity. Jam not even sure that all the specimens I 
have referred to this species will prove to be co-specific ; nor would I undertake in all 
cases to distinguish between this form and S. copeana. 
As a very general rule the species is smaller than S. copeana (length about 50-60
