MILLIPEDS OF PANAMA—LOOMIS 115 
Diagnosis: Closely related to E. bicornis Brolemann but con- 
siderably smaller and apparently with a longer stria on each side of 
segment 1 and no indistinct ones near the posterior margin; gonopods 
quite similar but with fewer spinelike hairs on the posterior median 
lobe. 
Description: Length of largest female 24 mm., width 1.5 mm.; 
48 segments and ocelli in 4 rows of 3-5—7-8, beginning near antennae; 
largest male (type) 19 mm. long, 1.2 mm. wide with 43 segments 
and ocelli in 3 rows of 3-6-8; other male with 40 segments and ocelli 
arranged 3-5-7. 
Segment 1 with raised rim of anterior margin beginning opposite 
lower corner of eye and extending around side to posterior margin; 
above it a single strong stria starting immediately behind upper 
end of margining rim, or even some distance above it, and extending 
obliquely downward and backward in a straight line to the posterior 
margin a short distance above the corner. Body segments with 
a well-impressed transverse sulcus, the surface behind it strongly 
convex; lateral striae of segments highest on sides of segment 4, 
where they reach a little over half way to the line of pores, rapidly 
restricted on segments 5, 6 and 7, behind which they are confined to 
the ventral surface and do not extend beyond tips of legs; pores larger 
than in other species here described, somewhat depressed in surface 
and encircled by a distinct ring. Last segment with apex very short, 
rounded, rather thick and considerably exceeded by the anal valves. 
Gonopods as shown in figure 7d, the posterior median lobe with 
about half the number of stiff hairs found in EF. bicornis. Ventral 
rim of segment 7 of male with two elevated lobes slightly less promi- 
nent than those of E. robusta but apparently more prominent than 
those of bicornis.

FicurE 7e-g 
Ho.totyre: Male, USNM myriapod collection 2650, rain forest, 
Cerro Campana, Panama, March 16, 1958, G. B. Fairchild and H. F. 
Loomis. 
AuLotTyPE: Female, USNM, same collection data as for holotype. 
Paratyre: Young specimen, USNM, same collection data as for 
holotype. 
Diagnosis: Although the gonopods indicate close relationship 
with E. bicornis from Costa Rica, there are evident differences; 
furthermore, the body is shorter, stouter, and with fewer segments 
than in that species or any other one known. 
Description: Male with 37 segments, 18 mm. long and 1.6 mm. 
in diameter; female same diameter, 15 mm. long with 36 segments.
