414 SUPPLEMENT. 
by the long ovipositor of the female, the dorsal segment of which is sharply pointed, 
and the ventral truncated or sinuated, and by the elongate-oblong, subdepressed form 
of body, the very gradually thickened hind thighs, and longish basal joint of the hind 
tarsi. The lower lobe of the eye is large and oblong, and the pro- and mesosternum are 
of considerable width. To this group belong, besides the foregoing, Nyssodrys signifera, 
N. propingua, N. simulata, N. efflicta, N. rodens, and N. excelsa, all from the Amazons, 
and WV. conspicillaris, Er., from Peru; to the same group belongs a subgroup of species 
including WV. incisa, NV. stillata, and NV. anceps, and NV. inclusa described below. Aber- 
rant species of the group, having much thicker (elongate-clavate) hind thighs and 
broader and shorter lower eye-lobes, are WV. alboplagiata, NV. lineolata, and N. ramea 
from the Amazons. 
3 (s). Nyssodrys inclusa. (Tab. X XV. fig. 4.) 
NV. stillate (Bates) affinis et similis. Angustissime oblonga, olivaceo-nigra; thorace vittis sex (2° utrinque 
abbreviata), elytris plagis e maculis agglomeratis maculisque suturalibus viridi-cinereis ; antennis longis- 
simis tenuibus castaneo-rufis, articulis apice fusco-nigris subtus et supra (multo sparsius) setulosis; oculis 
lobo inferiori oblongo mediocriter elongato; thorace quam in WV. caudata angustiori, minus trapezoideo, 
longe ante basin angulatim dilatato (nec spinoso nec tuberculato); elytris apice sinuato-truncatis, angulo 
suturali acuto, exteriori sat longe producto; pedibus sicut in MW. caudata; mesosterno late quadrato, 
postice haud angustato; prosterno multo angustiori. 
Long. 33-4 lin. 
Hab. Panama, Bugaba (Champion). 
A member of a subgroup having nearly all the structural characters of the NV. caudata 
group, including the long tubular female ovipositor with truncated ventral segment, and 
the emarginated dorsal and ventral plates of the male apical segment, but differing in 
colour and markings—olive-black, spotted (the spots variously agglomerated) with light 
greyish-ashy. The short sete on the antenne indicate an affinity with Sporetus.

Nyssodrys polyspila (p. 180). 
To the localities given, add:—Panama, Volcan de Chiriqui, Bugaba (Champion). 
Belongs to a distinct group, characterized by the smaller and shorter lower lobe of 
the eye (which is somewhat narrowed below), by the thorax being angulated (not spined) 
some distance from the base, the elytra transversely truncated, with the external angle 
toothed, the mesosternum broad as in Leptostylus, and the prosternum proportionally 
broad. The female ovipositor in the majority of the species is short and flattened, 
with the dorsal segment broadly rounded at the apex, but there are others closely allied 
in other respects in which the same segment is rather pointed. 
The species with obtuse ovipositors are closely allied to Sympagus, and might very 
well be removed to that genus, notwithstanding their more elongate and flattened form
