ZELUS. 259 
and the longer sulcus on the pronotum, the posterior tibiz simple in the female. An 
example from San Gerdnimo is figured. 
12. Zelus atripes, n. sp. (Tab. XV. fig. 22, 9.) 
@. Elongate, broad, shining, finely pubescent and also clothed with pallid erect hairs; testaceous, the 
anterior lobe of the pronotum with two small black spots on the disc in front, the connexival segments, 
the pleura, and the sides of the ventral segments each with a row of small black spots, the corium with 
a black mark at the base of the narrow apical portion, the membrane smoky; the legs (including the 
trochanters), rostrum, and antenne black; the head with a short black streak on each side at the base 
and another behind the eyes. Head narrowing posteriorly, shorter than the pronotum, the basal portion 
stout and cylindrical; antenne with the basal joint about as long as the head and pronotum united. 
Pronotum broadly truncate at the base; the posterior lobe dilated at the sides posteriorly, rugulose, the 
hind angles armed with a prominent triangular tooth, the basal margin strongly reflexed ; the anterior 
lobe smooth, sulcate down the middle, the anterior angles tuberculiform. Elytra extending to a little 
beyond the abdomen. Legs elongate, comparatively stout, pilose; the anterior and intermediate femora 
moderately thickened, the anterior pair as long as the third pair; the hind tibiee simple. 
Length 22, breadth (of the pronotum) 61 millim. 
Hab. Panama (Boucard). 
One example. The strongly dilated posterior lobe of the pronotum, the black 
legs, rostrum, and antenne, and the different coloration distinguish this species from 
Z. janus and its allies. The second joint of the rostrum is much longer than the first.
