PHYMATOPHOSUS.—PHYRDENUS. 503 
humeri, white, the femora and rostrum also annulate with white; the upper surface set with widely 
scattered, coarse, erect, blunt, light and dark sete, these becoming more numerous and crowded together 
on the dorsal elevations of the elytra, the prothorax with four fascicles of erect ochreous sete placed 
across the middle of the disc (the outer two small) and two at the apex ; the legs setulose. Head densely 
punctate, depressed between and above the eyes; rostrum short and very stout, squamose to near the 
tip, densely punctate and faintly carinate. Prothorax transverse, subconical, feebly constricted in front, 
deeply bisinuate at the base; densely punctate. Hlytra convex, subtriangular, broadly produced at the 
apex, strongly sinuate at the base, slightly compressed at the sides below the oblique humeral ridge ; 
seriate-punctate, the punctures subquadrate, the interstices densely, minutely punctulate, 2 and 4 each 
with two oblong setigerous prominences, 6 and 8 also a little raised, and 10 with a laterally projecting 
prominence below the base. Legs stout, the femora unarmed. 
Length 43, breadth 2; millim. 
Hab. Mexico, Frontera in Tabasco, Atlantic slope (/ége). 
One specimen. Larger than P. sqguamans, with the prothorax subconical in shape, 
the elytra nodose, and with a very large white apical patch, &c. 
3. Phymatophosus scapularis, sp.n. (Tab. XXIV. figg. 26, 26 a.) 
Subovate, black, the antenne ferruginous ; densely clothed with pale brownish scales, the elytra with a large 
whitish or brownish-white patch covering the apical declivity, the elevations each with a cluster of 
short, coarse, erect sete, the prothorax with four fascicles of erect ochreous setee—two on the disc 
and two at the apex, the legs setulose. Head densely punctate, depressed between the eyes; rostrum 
short and very stout, closely punctate and faintly carinate. Prothorax a little broader than long, conical, 
densely punctate. Elytra much wider than the prothorax, subtriangular, broadly produced at the apex ; 
the humeri broadly lamellato-dilatate, rounded externally and oblique behind; seriate-punctate, the 
punctures subquadrate, the interstices densely, minutely punctate, 2 and 4 raised towards the middle and 
below the base, 6 and 8 also slightly raised, 10 with a small prominence below the shoulders. Legs 
stout, the femora unarmed. 
Length 34, breadth 274; millim. 
Hab. Guatemata, El Reposo and Paraiso, Pacific slope (Champion). 
Two specimens. Smaller than P. multicristatus, the humeri strongly lamellato- 
dilatate, the prothorax narrower, conical.

The species belonging to the present genus, one of the very few of this division with 
toothed tarsal claws, are extremely like Conotrachelus setosus, Ros., but differ from 
_* To avoid delay in publication, the very numerous genera of this division will be dealt with as most 
convenient, irrespective of their relationship, no other course being possible with such a large amount of 
material awaiting examination. 
+ The S.-American genus Pterygomus, Jekel, also has toothed claws, but it belongs to the ‘“ Sophrorhinides.”
