90 RHYNCHOPHORA. 
49, Anchonus intricatus. 
Anchonus intricatus, Faust, Deutsche ent. Zeit. 1892, pp. 27, 47 (9) °. 
Hab. Panama }. 
Convex ; the prothorax subtransverse, strongly constricted near the apex and then 
abruptly dilated, a little narrowed towards the base, the surface setulose, densely, 
deeply punctate, with a slightly elevated median line; the elytra elliptic, remotely 
seriate-punctate, the dorsal interstices subcarinate, the alternate ones more raised 
towards the base, granulate and setose, the suture elevated, but not granulate. 
Length 5 millim.? 
RHYPARONOTUS. 
Rhyparonotus, Faust, Deutsche ent. Zeit. 1892, pp. 20, 33. 
Ten species of this genus have been described, all from Colombia and Venezuela, 
one only of which (&. scapha) is known to me by name. They appear to be rare 
insects, the three forms now added from Costa Rica or Nicaragua being represented 
in our collection by seven specimens. Ahyparonotus is closely allied to Anchonus, 
but differs from it in having the anterior coxe separated, and from Cestophorus in the 
relatively shorter scape to the antenne. The funiculus is 8-jointed, the eighth joint 
large and closely articulated to the club. The scrobes are shallow behind. ‘The eyes 
are flattened and almost smooth, and not easily seen. 
§1. Rostrum not constricted at the base. 
1. Rhyparonotus serripes, sp.n. (Tab. VI. fig. 17, ¢.) 
Elongate-ovate, black, the antenne and tarsi partly rufescent, the surface coated with an earthy incrustation ; 
the sete very short. Rostrum not constricted at the base, curved, a little shorter than the prothorax, 
granulate, rugusely punctured to the tip, obsoletely, longitudinally sulcate; scape reaching the anterior 
margin of the eye. Prothorax considerably longer than broad, somewhat rounded at the sides, gradually 
widening from the base to before the middle, and then narrowed to the apex and feebly constricted ; the 
surface granulate, except down the middle and along a sinuous space midway between this and the 
margin. LElytra about twice as long as the prothorax, oblong-oval, flattened on the disc, abruptly 
declivous behind, conjointly rounded at the apex ; seriate-punctate, the interstices 3, 5, and 7 (2, 4, 6 on 
the apical declivity) interruptedly costate, each with a scattered series of rounded, setigerous tubercles, 
which become more raised towards the tip, the tubercles smooth and shining at the summit. Ventral 
segments 1, 2, and 5, and the metasternum also, coarsely rugose. Legs rough, the femora granulate, the 
anterior and intermediate tibie sharply, and the posterior pair more finely, denticulate within. Anterior 
cox rather widely separated. 
Length 74-94, breadth 3-35 millim. (d¢.) 
Hab. Costa Rica, Caché, Volcan de Irazu (fogers). 
Three specimens, one of which is clean and immature. Separable from the 
following species by the non-constricted rostrum, the coarsely rugose under surface, 
the sharply denticulate inner edge of the tibie, &c.
