502 _ RHYNCHOPHORA. 
1. Dercynus micronyx, sp.n. (Tab. XXIV. figg. 23, 23a, b.) 
Subovate, broad, robust, black, the antenne in part ferruginous; densely clothed with coarse brown scales, 
with a few whitish scales intermixed, the elytra with a more or less distinct oblong mark on the suture 
below the base, an oblique line below the shoulders, and a common sinuate subapical fascia, whitish or 
ochreous, the femora subannulate; the elytra also sparsely set with very short, stout, blunt, semierect 
sete, which are more closely placed on the dorsal elevations. Head closely punctate, the eyes moderately 
distant; joints 1 and 2 of the funiculus subequal in length; rostrum punctato-striate, carinate at the 
base. Prothorax strongly transverse, rounded at the sides anteriorly, constricted and much narrowed in 
front, deeply bisinuate at the base; closely punctate and also carinate. Elytra barely one-half wider 
than the prothorax, somewhat flattened on the disc and abruptly declivous behind, subparallel to about 
the middle, the sides subangularly dilated above the intermediate coxe, the apices broadly produced, the 
humeri obliquely truncate in front; coarsely seriate-punctate, the interstices rugulose, 2, 4, and 6 here 
and there raised. Beneath closely, finely punctate. 
Length 43-5, breadth 23-24 millim, 
Hab. Guatemata, Panzos in Vera Paz (Champion). 
Two specimens. The broad form, the short, stout legs, the subparallel elytra, with 
the sides subangularly dilated before the middle and the apices broadly produced, 
sufficiently distinguish D. micronyz. 
PHYMATOPHOSUS. 
? Cryptacrus, Kirsch, Berl. ent. Zeitschr. 1869, p- 198 (nomen preeocc.). 
Phymatophosus, Faust, Stett. ent. Zeit. 1896, pp. 54, 83. 
Faust included Phymatophosus amongst the group “ Cryptorhynchides vrais” of 
Lacordaire, and placed it next Apteromechus, but as the metathoracic episterna are 
extremely narrow or not visible (when the scales are removed) the genus really belongs 
to the “ Tylodides,” near Oxypterus, from which it differs in the small, laterally placed 
eyes, the unarmed femora, the presence of a small scutellum, &c. The mesosternum 
is very prominent and raised above the level of the metasternum, and its anterior 
edge is feebly emarginate. The ventral segments 2-4 are equal in length. The 
tarsal claws are very small, and narrowly separated or subconnate.

Phymatophosus squamans, Faust, Stett. ent. Zeit. 1896, p. 83°.

Numerous examples, varying greatly in size. The feeble elevations on the elytra 
(not mentioned by Faust, but visible in one of his types) are sometimes prominent and 
they tend to form two oblique series on the disc of each elytron. The seriate punctures 
are fine and placed in narrow strie. 
2. Phymatophosus multicristatus, sp.n. (Tab, XXIV. figg. 25, 25 a.) 
Subovate, piceous, the autenne ferruginous ; densely clothed with pale brownish scales, the elytra with 
a very large patch covering the apical declivity, and an oblique streak extending inwards from the
