This remarkable genus contains two closely allied species of large size, both inhabiting 
Colombia; one of these we now trace as far north as Guatemala. Phrenapates bears a 
certain superficial resemblance to Passalus, and was indeed considered by its describer 
to be closely related to that genus; it is of similar habits, and often found in company 
with species of that genus.

This species is closely allied to P. latreillei, and differs solely from that species in the 
shape of the ligula and mentum; it varies considerably in size, and also in the presence 
or absence of wrinkles upon the head; some of the Nicaraguan specimens are no larger 
than P. latreillet. I met with P. bennett in plenty in decaying timber in the humid 
forest region of Chiriqui, and frequently dug it out of cylindrical burrows, probably 
made by the larvee, in the solid wood. 
DAOCHUS. 
Mentum transverse, the sides deflexed and deeply concave within, the anterior angles rounded; antennary 
orbits not swollen, broadly, but feebly, emarginate; ligula strongly exserted, very large and prominent, 
rounded in front, and with a deep rounded excavation (separated by a strong longitudinal carina) on 
each side, and into which the labial palpi are inserted; inner lobe of the maxille armed on the inner 
side, and the outer lobe at the apex, with long coarse sete ; last joint of the maxillary, and also that of 
the labial, palpi elongate ovate, rounded at the apex; mandibles long, stout, exserted, deeply cleft at the 
apex, concave within at the base above (for the reception of the prominent labrum, which is rounded in 
front) ; antenne perfoliate, short (not reaching to the middle of the prothorax), the basal joint stout, the 
third short and scarcely as long as the united fourth and fifth, the fourth to the eighth transverse, and 
gradually widening outwardly, the ninth and tenth suddenly wider, strongly transverse, and forming with 
the eleventh (which is nearly as long as the united ninth and tenth, and rounded at the apex) a distinct 
3-jointed club, the last three or four joints setose ; head very broad, angularly extended on each side, not 
deeply sunk into the prothorax; epistoma confounded with the front, the anterior portion abruptly 
declivous, broadly, but not deeply, emarginate; antennary orbits not swollen, broadly but feebly 
emarginate ; eyes rather small, inserted at the extremity of the lateral angular extension of the sides 
of the head, rounded, distant from the thorax, the inferior portion small, very feebly emarginate in front ; 
prothorax strongly transverse, transversely convex, the sides and base strongly margined, the basal half 
of the former crenulate; scutellum very minute, almost obsolete; elytra very short and convex, scarcely 
one and a half times the length of the prothorax, truncate at the base, very coarsely and deeply punctate- 
striate (the stria next the suture extending in a straight line direct to the base, the scutellar stria
