64 RHYNCHOPHORA. 
first and second ventral segments connate at the middle; metasternum short; femora strongly clavate 
and acutely toothed ; tibia sinuous within, the claw arising near the inner apical angle in the ¢, and 
from about the middle of the apical margin in the 9, in which sex the inner apical angle is more or 
less mucronate, and also furnished with two matted spine-like pencils of hair at the tip; penultimate 
tarsal joint bilobed. , 
The three species referred to this genus, which will also include at least one South- 
American form, are very like some of the members of the group Anchonina, from 
which they may be distinguished by the more exserted, strongly punctured, and less 
globose head. The very widely separated eyes, the partially connate first and second 
ventral segments, and the peculiar sculpture of the upper surface separate them from 
Hilipus, to which otherwise they are closely allied. The fusion of the first two ventral 
segments is a character common to most of the Anchonina. 
1. Anchonomorpha occulta, sp.n. (Tab. IV. figg. 28, 28a, 2.) 
Oblong-ovate, dull above and shining beneath, black, the antenne and tarsi partly rufescent ; clothed above 
with scattered, narrow, minute, brownish scales, these being coarser and more elongate on the elytral 
elevations, the entire upper surface often coated with an earthy incrustation ; the under surface with 
very few scales; the legs thickly clothed with curved setiform scales. Head densely punctate, foveate 
between the eyes; rostrum stout, slightly longer than the prothorax, moderately curved, rugosely 
punctured, 5-carinate ; joints 1 and 2 of the funiculus subequal in length. Prothorax a little broader 
than long, rounded at the sides anteriorly, considerably narrowed in front, and slightly so behind, the 
base strongly bisinuate; the surface densely, rugosely punctured, somewhat uneven towards the apex, 
two feeble elevations being sometimes visible on the disc before the middle. Elytra fully one-half wider 
than the prothorax, moderately long, parallel in their basal half, conjointly rounded at the apex, the 
base feebly trisinuate, the humeri rounded ; seriate-punctate, the interstices 2-7 each with a scattered 
row of oblong or rounded elevations, those on the third and fifth being the most conspicuous. Metasternum 
foveolate at the sides. Ventral segments 1-4 very sparsely and finely, and 5 closely, punctate, the latter 
transversely depressed in the middle at the apex in the ¢. 
Length 6-9, breadth 24-4 millim. (¢ 2.) 
Hab. Mexico, Toxpam (Sallé); Guatemata, Sinanja in Vera Paz (Champion) ; 
Nicaragua, Chontales (Belt); Costa Rica, Tucurrique (Mus. Dresden); Panama, 
Bugaba, Volcan de Chiriqui (Champion). 
Found in plenty in Chiriqui. Differs from the following species in the absence 
of the prominences on the prothorax, though two of these are sometimes traceable 
on the disc. 
2. Anchonomorpha tuberculifera, sp. n. (Tab. V. fig. 1.) 
Oblong-ovate, broad, opaque above and slightly shining beneath, pitchy-black, the legs and antenne partly 
rufescent; clothed above with minute brown scales, these being coarser and more elongate on the elytral 
elevations, and also with scattered, short, erect setae, the inequalities of the surface more or less coated 
with an earthy incrustation ; the under surface with a few scattered scales and erect sete; the legs with 
setiform scales. Head densely punctate, foveate between the eyes; rostrum moderately curved, stout, 
rugosely punctured, 5-carinate; joint 2 of the funiculus slightly shorter than 1. Prothorax a little 
broader than long, the apex produced over the base of the head and emarginate in the centre, the sides 
rounded at the middle, rapidly converging in front, and sinuate behind, the base strongly bisinuate; the 
surface uneven, closely, irregularly punctate, with six prominent rounded tubercles—four in a transverse
