262 HEMIPTERA-HETEROPTERA. 
smoky ; the abdomen with the fifth and sixth dorsal segments and a transverse fascia at the base of the 
others black; the ventral segments at the sides and the pleura with a series of small black spots; the 
rostrum annulated with black at the base; the antenne black; the femora flavous, triannulated with 
black, the tarsi and tibie blackish, the latter with two or three pale rings towards the base. Head 
about as long as the pronotum, narrowing behind the eyes, the basal portion cylindrical ; antenne very 
slender, longer than the body, the basal joint about as long as the head, pronotum, and scutellum 
united. Pronotum narrowing from the hind angles forwards, the latter armed with a long, acute, outwardly 
directed spine; the anterior lobe smooth, sulcate down the middle; the anterior angles transversely 
tuberculiform and rather prominent; the posterior lobe rugulose, without carinez on the disc, the basal 
margin narrowly reflexed. Elytra extending considerably beyond the abdomen. Legs very long and 
slender, sparsely pilose. 
3. Third antennal joint thickened to beyond the middle; terminal genital segment armed at the apex with a 
long, slender, upwardly curved, hooked spine. 
Length 123-16, breadth 24-23 millim. (¢ @.) 
Hab. Panama, Bugaba (Champion). 
One pair, in a perfect state of preservation. The peculiar coloration of the head and 
pronotum separates this species from all others of the genus known to me.

We possess three specimens of this species, agreeing perfectly with the type. The 
males have the third antennal joint thickened to near the tip, and the terminal genital 
segment produced at the apex into a short, stout, pointed tooth. The second joint of 
the rostrum is twice the length of the first. There are two females of Z. tetracanthus 
amongst the unnamed specimens in the Stockholm Museum; one of these has the 
posterior lobe of the pronotum pale, and the lateral and dorsal spines reduced to blunt 
teeth.

A Tropical-American genus easily recognizable by the inflated posterior lobe of the 
pronotum, this being produced forwards so as to nearly cover the anterior lobe as seen 
from above and backwards over the scutellum. WV. dactrianus will probably have to
