76 RHYNCHOPHORA. 
distinctly so on the disc, the disc with indications of an abbreviated median carina. LElytra subelliptic, 
convex, wider at the base than the prothorax, seriate-punctate, the interstices 2-7 each with a series of 
oblong or rounded, prominent, setigerous tubercles, those at the base of 3 and 5 cariniform, the suture 
also tuberculate a little beyond the middle. Beneath very coarsely punctate, the ventral segments 1 and 2 
connate. Femora coarsely punctate and minutely granulate. 
Length 63-8, breadth 33-37 millim. (<¢.) 
Hab. Nicaragua, Chontales (Belt). 
Two males. In this species the prothorax is distinctly binodose on each side before 
the middle, so as to appear subangularly dilated. It is not unlike A. obovatus and 
A. validus, but has a more transverse, finely granulate prothorax ; the elytra are less 
rounded at the sides, broader at the base, and with more numerous tubercles, these 
being not so prominent as in A. obovatus; and the setosity is shorter. 
15. Anchonus helleri, sp. n. (Tab. V. figg. 19,19 a, ?.) 
Oblong-obovate, slightly depressed above, black ; the sete coarse and forming fascicles on the prothorax and 
elytra. Rostrum moderately stout, slightly thickened towards the base, coarsely punctate. Prothorax 
a little broader than long, constricted and much narrowed in front and gradually narrowing behind, 
coarsely varioloso-punctate, with the narrow interspaces here and there granulate, distinctly binodose at 
the apex and also on each side before the middle, and with the sete clustered together at these places, 
the disc with an abbreviated sinuous smooth median line anteriorly. Elytra oblong-ovate, at the base a 
little broader than the prothorax, seriate-punctate, the interstices 2-7 each with a scattered series of 
oblong or rounded setigerous tubercles, those at the base of 3 and 5 forming a short ridge, the suture 
granulate. Beneath somewhat coarsely punctate; ventral segments 1 and 2 connate and level at the 
middle. 
Length 8, breadth 41, millim. (9.) 
Hab. Costa Rica, Piedras Negras (Mus. Dresden). 
One specimen, communicated by Dr. Heller. Not unlike A. horridus, but much 
larger, with a rougher fasciculate prothorax, which is binodose laterally and in 
front. The connate first and second ventral segments, the narrower terminal joint 
of the funiculus, and the less rounded sides of the prothorax and elytra separate it 
from A. articulatus and A. brevisetis; and the more depressed form, &c., from 
A. obovatus and A. validus. 
16. Anchonus subcristatus, sp. n. (Tab. V. figg. 20, 204, 3.) 
Elongate-ovate, black, the antenne and tarsi obscurely rufescent; the sets long, coarse, and abundant, and 
showing a tendency to form four fascicles on the prothorax. Rostrum (¢) curved, stout, cylindrical, 
slightly constricted at the base, coarsely punctate and longitudinally wrinkled, ( 2 ) slightly thickened 
towards the base, and closely, coarsely punctate to the tip. Prothorax about as long as broad, a little 
shorter in the 2, the sides rounded at the middle, converging thence to the base and apex, and constricted 
in front; the surface closely punctate, except along a narrow space down the middle, with the inter- 
spaces opaque and here and there transversely or obliquely raised, feebly binodose and fasciculate at. the 
apex, the set also forming two indistinct fascicles on the disc. Elytra ovate or oblong-ovate, convex, 
at the base scarcely wider than the prothorax ; seriate-punctate, the interstices 2-7 each with a series 
of oblong or rounded prominent setigerous tubercles, the suture also tuberculate. Femora coarsely 
punctate. 
Length 44-5, breadth 2-23 millim. (¢ 2.)
