The present male differs from the Guianan males referred to 
above in the proportionately longer mesonotum, with minute 
granules more regular and interspersed vdth larger granules 
laterad, vdiich are more numerous and surpass in size the few 
homologous larger granules found in those individuals, while 
the tegmina are shorter, much more truncate and show a strik- 
ing pale transverse l)and, and the limbs are heavier and pro- 
portionately more elongate. 
The tegmina in their l)revity show closer agreement with species 
of the Stratocles Division of the Pseudophasminae, but the char- 
acter of the limbs indicates that chocoensis is a meml)er of the 
Pj’exasjies Division. In fact the species is unquestionably a 
member of the genus Isagoras, showing apparently the maximum 
tegminal reduction.

Type no. 740.] 
Size metlium, form very slender, much as in plagintus. Head almost 
smooth, surface showing a few suljobsolete granules; cheek one and one-third 
times as long as eye; ocelli iirominent, forming a triangle slightly broader 
than deep, median ocellus distinctly smaller than lateral ocelli. Antennae 
extending well beyond aitices of wings, segments increasing greatly in length 
to near distal portion, which is briefly segmented. Pronotum almost smooth, 
with surface showing a few subobsolete granules, transverse sulcus distinct, 
ce])halic portion with lateral and transverse sulcus near cephalic margin dis- 
tinct. Mesonotum with a distinct medio-longitudinal sulcus, surface regularly 
supplied with numerous minute granules and with (eight and ten) irregularly 
idaced heavy granules on each side. Mesosternum with surface granuloso- 
rugulose. Tegmina short, caudal margin transverse, rounding broadly into 
the sutural margin, shoulders low, bluntly and evenly rounded. Wings fully 
developed. Distal portion of abdomen missing. Limbs unarmetl. Ceph- 
alic femora compressed, with dorso-internal carina moderately elevated. 
Median and caudal femora with dorsal and ventral margins carinate; ven- 
tral surface medio-longitudinally carinate, this weak on median femora, 
strong on caudal femora. Caudal metatarsus distinctly shorter than com- 
bined length of succeeding joints. Arolia moderately well developed. 
Head, pronotum and mesonotum bister, the former with a suffusion of 
mummy brown about the ocelli, the latter with the larger lateral granules 
mummy brown. Antennae mummy brovm proximad, cinnamon-buff in 
remaining portions, with intersections of the longer joints tinged with cin- 
namon-buff. Tegmina proximad bister, shading to snuff brown distad, 
ilorsad with a narrow transverse band of pinkish buff before the shoulders, 
laterad in all but proximo-ventral and disto-dorsal portions buffy, washed
