180 LONGICORNIA. 
6. Nyssodrys polyspila. 
Leiopus polyspilus, White, Cat. Long. Col. B. M. i1. p. 383°. 
Hab. Guatemata, Panima (Champion); Honpvras 1. 
Allied to WV. vitticollts (Amazons), from which it differs at once in the thorax having 
on its dorsal surface, instead of white stripes, rounded whitish spots, eight in number, 
arranged in two transverse rows. 
7. Nyssodrys pulverea. 
Oblongo-ovata, convexiuscula, ochraceo-cinerea, thoracis vittis dorsalibus duabus, scutello elytrorumque 
plaga transversa (nec suturam nec marginem attingente), macula prope scutellum, guttulis suturalibus 
liturisque prope apicem atro-fuscis; antennis rufo-piceis, articulis apice fuscis; oculis subtus haud 
elongatis ; thorace mox pone medium utrinque angulato, lateribus antice et postice obliquis; elytris vix 
punctulatis, apice sinuatim truncatis angulo exteriore paullo producto; pedibus ochraceo-cinereis, tibiis 
apice tarsisque nigris, femoribus modice clavatis, tarsis posticis articulo primo modice elongato. 
©. Abdomen segmento apicale paullo ultra elytra prolongato, apice obtuso. 
Hab. Mexico, Cordova (Sal/é). 
8. Nyssodrys letifica. (Lepturges letificus, Tab. XII. fig. 19.) 
Lepturges letificus, Bates, Trans. Ent. Soc. 1872, p. 237. 
Hab. Nicaraaua, Chontales (Belt). 
The very considerable width of the mesosternum necessitates the removal of this 
and the three following species from the genus Lepturges, in which I had originally 
placed them, and to which they seem naturally to belong by their slender form and the 
style of their markings and coloration. The lateral spine of the thorax, always well 
developed in Lepturges, in WV. letifica is wanting. All the specimens taken by 
Mr. Belt appear to be males; at least none of them shows a trace of an ovipositor. 
9. Nyssodrys venusta. 
Lepturges venustus, Bates, Ann. & Mag. Nat. Hist. ser. 3, xii. p. 8372! (1868). 
Hab. Nicardeva, Chontales (Belt).—Soutn America, Amazons’. 
A single example from Mr. Belt’s collection agrees with specimens from the Amazons 
in every respect, except that the elongated black spots of the elytra parallel to the 
suture are joined together, and the posterior one is also joined to the sutural border. 
As the elytral spots are somewhat variable in the Amazonian examples, I have little 
hesitation in referring the Chontales insect to the same species. 
10. Nyssodrys circumscripta. (Lepturges circumscriptus, Tab. XII. fig. 16.) 
NV. venuste similis at brevior ; grisea, antennis pedibusque atro-fuscis ; supra griseo-ochracea, thorace vittis 
latis duabus, elytris vitta laterali alteraque ata subsuturali, maculam griseam medianam includente et ante 
apicem desinente atro-fuscis; thorace trapezoidali, lateribus fere rectis, pone spinam brevem exstantem
