1. Paratenetus tibialis. (Tab. X. fig. 22, ¢.) 
Rather convex, reddish-brown, rarely piceous, sparsely clothed with rather long erect hair. Head coarsely and 
closely punctured, transversely impressed in front; antenne stout, rather long, with the three joints of 
the club greatly widened in’ both sexes (these joints coarsely punctured), still stouter and broader in 
the male, black, the basal joints often more or less reddish; prothorax broader than long, distinctly 
narrowing anteriorly, widest at or a little before the base, the sides irregularly but not coarsely 
erenulate, the posterior angles acute, the anterior angles not very prominent, the surface rather coarsely 
punctured (not quite so closely or coarsely as the head), the disc often darker; elytra widening from the 
base, widest a little beyond the middle, thence obliquely narrowing, and the apex somewhat produced, 
strongly margined, a shallow depression on each side of the base just within the shoulders, the surface 
rather coarsely and irregularly punctured, the punctures finer and not so closely placed on the disc, 
varying in colour, unicolorous reddish-brown, or (more frequently) piceous with the sides reddish-brown ; 
legs reddish-brown or piceous, rather stout; tibia (the intermediate pair especially) slightly curved and 
swollen in both sexes, in the male the anterior pair armed on the lower side about the middle with a 
sharp tooth, and the intermediate and posterior pairs denticulate on the inner side and with their inner 
apical angles sharply produced ; beneath shining, sparingly and finely punctured. 
Length 43-5} millim. (¢ 2.)

Many examples. In Guatemala I only met with this species on the Atlantic slope, 
in or near the Polochic valley. This distinct species will be readily known by the 
very stout black antennal club, the structure of the tibie in the male, the shape of the 
elytra, &c. 
A male example from San Juan is figured. 
2. Paratenetus grandicornis.

The brief characters given by Motschoulsky for this species are as follows:— 
“Thorax armed laterally with very short teeth or simply crenulated; elytra oblong 
oval, slightly convex, form of Corticaria; club of the antennee black and greatly dilated, 
the base clear. Length ¢ lin.” This species would seem to be allied to P. tibialis, 
though very much smaller and with the elytra differently shaped. 
9. Paratenetus ruficornis. (Tab. X. fig. 23,2.) 
Moderately convex, unicolorous reddish-brown, sparsely clothed with decumbent and also with rather long erect 
hair. Head coarsely and subconfluently punctured, transversely impressed in front ; antenne stout, rather
