1. Aneurus montanus, n. sp. (Tab. VII. figg. 26, 9; 26a, antenna.) 
Ovate, dull, black, the abdomen, and sometimes the front of the head, the basal half of the pronotum, and the 
apical margin of the scutellum also, rufo-piceous, the elytra whitish-yellow at the base. Head rugose 
and obsoletely granulate, with acute, outwardly directed, spiniform, antenniferous tubercles and short 
post-oeular spines; antenne about twice as long as the head, joints 1 and 2 oval, 3 and 4 cylindrical, 
4 slightly thickened towards the apex, 1 stout, 2 much more slender and much shorter than 1, 3 longer 
than 1, 4 nearly twice as long as 3. Pronotum subtruncate at the base, rugulose and obsoletely granulate. 
Scutellum nearly or quite as long as the pronotum, and similarly sculptured. Connexivum very finely 
rugulose. Legs rather long, the femora moderately thickened and finely granulate. Terminal genital 
segment of the male long and convex, extending beyond the genital lobes, transversely rugulose. 
Length 5-53, breadth 2-24 millim. (¢ 2.) 
Hab. Guatemata, Totonicapam 8500 to 10,500 feet (Champion). 
Six examples, probably found under pine-bark. This insect approaches the European 
A. levis (Fabr.), and has a similarly formed scutellum ; but differs from it in the acute 
antenniferous tubercles and the longer apical joint of the antenne. It has the femora 
less thickened than in the other Central-American species.
