240 HETEROMERA. 
long, with the three joints of the club much widened in both sexes (these joints finely punctured and the 
two lower ones transverse), still broader and stouter in the male, entirely ferruginous ; prothorax com- 
paratively broad, wider than long, slightly rounded at the sides, distinctly narrowed anteriorly, the sides. 
denticulate (about eight denticles on each side), the angles acute (each formed by one of the lateral 
denticles), the surface coarsely and subconfluently punctured; elytra widening slightly from the base 
to beyond the middle, broadly rounded at the apex, narrowly margined, the surface rather coarsely 
irregularly and somewhat closely punctured, the punctures finer and not so closely placed on the disc ; 
legs moderately stout, ferruginous ; anterior tibie with a small triangular tooth on the lower side a little 
beyond the middle, the intermediate tibia also with a tooth on the inner side some distance beyond 
the middle, and the inner apical angles of the two hinder pairs narrowly produced in the male; beneath 
shining, finely and sparingly punctured. 
Length 4-43 millim. (¢ 2.) 
Hab. Panama, Bugaba (Champion). 
Numerous specimens. PP. ruficornis will be identified by its ferruginous antenne, 
stout antennal club (in the male about as stout as in the female of P. tibialis), the 
coarsely denticulate sides of the thorax, &c. It is quite possible that P. Jlebast, 
Spin. (Essai monogr. Clér. ii. p. 119, t. 44. fige. 6 & 66), from Colombia, is the female 
of P. ruficornis, but as I cannot reconcile our insect with the figure given I prefer to 
describe it. Compared with P. punctatus the present insect is larger, the antennz 
entirely ferruginous and with the club very much stouter, the thorax more narrowed 
anteriorly, and much more coarsely denticulate at the sides, &c. 
4. Paratenetus villosus. (Tab. X. figg. 24,9; 24a, labium; 240, maxilla 
and maxillary palpus.) 
Convex, dark reddish-brown, sometimes lighter, somewhat thickly clothed with long erect hair. Head coarsely 
and subconfluently punctured, transversely impressed in front; antennse stout, rather long, the club mode- 
rately stout, closely punctured, similar in both sexes, and the two lower joints rather broader than long, 
ferruginous, the club piceous ; eyes large; prothorax transverse, widest at or a little before the middle, the 
sides slightly rounded and narrowing anteriorly, the rather prominent lateral margins irregularly crenulate, 
the posterior angles acute, the anterior angles obtuse, the base in the middle transversely grooved within, 
the surface rather more coarsely punctured than the head, the punctures more or less confluent ; elytra 
long, widest beyond the middle, convex, strongly margined, the surface coarsely and rather closely punc- 
tured (the punctures coarser, closer, and more or less confluent outwardly) and transversely and irregularly 
wrinkled towards the sides and apex; legs ferruginous, the femora and tibixs sometimes infuscate ; 
anterior and intermediate tibiee slightly curved, the anterior pair armed with a sharp tooth on the lower 
side about the middle, and the basal half of the latter and of the posterior pair also finely denticulate. 
within, and the anterior femora with a strong blunt tooth at the extreme base beneath in the male. 
Length 52-63 millim. (3 9.) 
Hab. Mexico, Jalapa (Hége); Guaremata, San Gerdnimo (Champion); Panama, 
Volcan de Chiriqui (Champion). 
Six examples. This, the largest species of the genus, is allied to P. punctatus, but 
will be known from that insect by its much larger size, the thorax less coarsely crenu- 
late at the sides, the limbs stouter, the club of the antenne broader and stouter and. 
the two lower joints not so transverse, the more pronounced male characters, &c. 
We figure a male example from Jalapa.
