Hab. Mexico (Sallé, in Mus. Holm.1?), Medellin and Atoyac in Vera Cruz, Teapa in 
Tabasco (H. H. Smith), Valladolid and Temax in Yucatan (Gaumer); GuATEMALA, 
Tocoy and Chiacam in Vera Paz (Champion); Honpuras, Ruatan I. (Gaumer) ; 
Nicaragua, Chontales (Janson); Panama, Bugaba, Volcan de Chiriqui, Caldera, David 
(Champion). 
Sent in abundance from Yucatan. In nearly all the specimens seen the short lateral 
spines of the pronotum are black. The femora are usually reddish at the apex, 
sometimes with a narrow dark ring before the tip, and in one of the examples from 
Bugaba they are faintly annulated with fuscous; the tibiz in some specimens are 
also faintly annulated with fuscous. The females are considerably larger than the 
males. The latter have the third antennal joint thickened to beyond the middle, 
and the terminal genital segment armed at the apex with a long, acute, upwardly 
curved spine. A male from David is figured.

Hab. Mexico? (Mus. Holm.** ; coll. Signoret}, in Mus. Vind. Cas. ; Sallé). 
This species is very closely allied to Z. nugax, and perhaps not really distinct from 
it. The types of Z. mimus and Z. wmbratilis are before me, and I am unable to 
separate them. Both appear to have the basal joint of the antenne a little longer 
than in Z. nugax; in the type of the female of Z. mimus the posterior lobe of the 
pronotum is pale. The antenne and legs are darker, and the latter a little more 
slender, than in Z. nugaz. The pronotum has a very short slender spine at the lateral 
angles and the base is very feebly margined. ‘The single specimen received by us, a 
male, is in a mutilated condition. The sexual characters are similar to those of 
Z. NUgax. 
17. Zelus nigromaculatus, n. sp. (Tab. XV. fig. 26, 3.) 
Very elongate, narrow, slightly shining, sparsely pubescent; flavous, the head with an oblong spot on the 
tylus in front, two posteriorly converging lines on the ante-ocular portion, and two oblong marks on each 
side of the post-ocular portion (placed one behind the other, and connected in one example), black ; 
the pronotum with a transverse fascia on the anterior lobe before the apex and two fascie on the 
posterior lobe—one in front and the other before the base,—the two latter connected along each side of 
the middle of the disc, and the lateral spines, nigro-fuscous or black ; the scutellum fuscous at the sides 
anteriorly ; the clavus and corium fuscous, the nervures of the latter flavous; the membrane and wings
