DIORY MERELLUS. 258: 
One specimen. Recognizable by the oblong scutellum, the six sharply-cut dorsal 
strie of the elytra, the somewhat swollen humeri, and the castaneous colour. 
6. Diorymerellus rubripennis, sp. n. 
Subrhomboidal, shining, nigro-piceous, the antennz, anterior and intermediate tarsi, and hind legs obscure 
ferruginous, the elytra and the ventral segments 3-5 rufous; glabrous above, the under surface and. legs 
with minute scattered scales. Head transversely grooved between the eyes; rostrum arcuate, very 
little longer than the prothorax, moderately stout, finely punctate, strigose and rugulose at the sides; 
antennal club oblong-ovate. Prothorax transverse, subconical, slightly depressed at the base on each 
side of the median lobe, constricted in front; smooth, the apical constriction with a transverse row of 
punctures. Scutellum oblong-subquadrate. Elytra wider than the prothorax, gradually narrowing 
from a little below the base, conjointly rounded at the apex; each elytron with six sharply-cut, obsoletely 
punctured strie on the disc and two marginal ones beneath, the seventh and eighth obliterated, the 
interstices broad, smooth, and flat. Beneath coarsely, the ventral segments 2-5 very sparsely and finely, 
punctate. Prosternal excavation deep, subtriangular. Anterior coxe separated by about their own 
width. Legs rather slender, very short, closely punctate ; intermediate and posterior femora shallowly 
sulcate beneath ; tibize narrow, almost straight ; tarsal claws minute, narrowly separated. 
Length 23, breadth 14 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
_ One specimen. Much smaller than D. histerotdes, the elytra and the apical half of 
the abdomen rufous, the legs shorter and much more slender. The prothorax is less 
‘constricted in front than in D. castaneicolor, and the head, prothorax, and legs are 
nigro-piceous. ‘The hinder femora are shallowly sulcate beneath, much as in 
Diorymerus. 
7. Diorymerellus histeroides, sp.n. (Tab. XIV. fig. 11.) 
Subovate, somewhat flattened above, shining, black, the apical two-thirds of the elytra rufous, the base of the 
antenne ferruginous; glabrous, above and beneath. Head almost smooth, transversely grooved and 
foveate between the eyes; rostrum moderately stout, arcuate, about as long as the prothorax, sparsely, 
finely punctate, the antenne inserted at the middle, the antennal club ovate. Prothorax transverse, 
with the sides arcuately converging from the base, strongly constricted in front, smooth. Scutellum 
smooth and flat, transversely subquadrate. Elytra gradually narrowing from a little below the base, the 
humeri rounded and not prominent; each elytron with six sharply-cut, finely-punctured stria on the 
disc and two marginal ones beneath, the seventh and eighth obliterated, the interstices broad, smooth, and 
flat. Beneath very sparsely and finely, the meso- and metasternal side-pieces coarsely and closely, 
punctate. Prosternum deeply excavate, the sulcus limited posteriorly by a U-shaped ridge between the 
cox. Legs short ; intermediate and posterior femora flattened beneath ; tarsal claws small, free, 
Length 33, breadth 2,1, millim. (2 ?) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. This insect has the facies of a Histerid and the general coloration 
of the European Baris analis. The six dorsal strize of the elytra are sharply cut, and 
the seventh and eighth are obliterated. ‘The tarsal claws are less contiguous than in 
the other species referred to Diorymeretlus.
