EUBULUS. 567 
shallowly foveate in the middle. Metathoracic episterna broad. Legs stout and rather short; femora 
each with a sharp tooth, and with indications of a small denticle exterior to it. 
Length 84, breadth 5,5 millim. (do ?) 
Hab. Guatemata, Las Mercedes, Pacific slope (Champion). 
One specimen, with the vestiture of the head and prothorax partly abraded. Larger 
and more robust than EF. nigricollis, the sculpture of the prothorax very different, the 
head with a smooth fovea in front of each of the eyes, the under surface very coarsely 
punctate, the vestiture of the elytra otherwise coloured. 
44, Hubulus irrubescens, sp. n. (Tab. XXVIII. figg. 5, 5a, 2.) 
Ovate, opaque, black, the antennwy ferruginous; the prothorax sparsely, the rest of the surface somewhat 
thickly, clothed with moderately coarse, fulvous scales, those on the prothorax clustered into curved lines, 
the elytra with intermixed fascicles of whitish scales, the prosternum, the base of the anterior femora, 
and the anterior cox also variegated with white, the mesosternal side-pieces with a white spot, the 
femora subannulate. Head rugosely punctate, shallowly sulcate on each side between the widely 
separated eyes, the transverse frontal depression limited anteriorly by an interrupted, irregular ridge ; 
rostrum arcuate, stout, nearly reaching the metasternum, rugosely punctate and carinate at the base, and 
thence to the apex minutely punctate, the antenne inserted at the middle, joints 1 and 2 of the funiculus 
subequal in length, the club cvate. Prothorax strongly transverse, feebly constricted and much narrowed 
in front, the sides arcuately converging from the base; closely punctate and sharply carinate. Elytra 
wider than the prothorax, oblong-subcordate ; seriate-punctate, the interstices 3, 5, 7, and 9 sharply 
costate. Beneath closely punctate. Metathoracic episterna narrow. Legs moderately long, stout ; 
anterior femora bidentate, the outer tooth small, the intermediate and posterior femora sharply unidentate. 
Length 74, breadth 4 millim. (@.) 
Hab. Guatemaua, Pantaleon, Pacific slope (Champion). 
One specimen. Larger and more oblong than &. nigricollis; the flanks of the 
prothorax not densely squamose, the disc more coarsely and less closely punctate ; 
the eyes widely separated; the vestiture of the elytra more uniformly distributed. 
45, Bubulus nigricollis, sp.n. (Tab. XXVIII. figg. 6, 6a.) 
Subrhomboidal, black, the antenns, and sometimes the apical half of the rostrum also, ferruginous; the entire 
disc of the prothorax, and a broad space down the suture of the elytra, widening at the base and apex, 
clothed in great part with small black scales, the rest of the upper surface, the flanks of the prothorax, 
and the legs with intermixed reddish-brown and ochreous scales, the latter condensed into an interrupted 
oblique fascia on each elytron below the base and various scattered spots, the elytra also set with short, 
erect, setiform scales, the vestiture of the under surface reddish- or dark brown, the femora subannulate. 
Head closely punctate, the transverse frontal depression limited anteriorly by the oblique carina above 
the eyes, the latter narrowly separated; rostrum arcuate, widened towards the base, rugosely punctate 
and carinate in its basal third, and almost smooth thence to the apex, the antenne inserted far behind 
the middle, joints 1 and 2 of the funiculus subequal in length, the club ovate. Prothorax strongly 
transverse, rapidly narrowing from near the base; densely punctate and sharply carinate. LElytra 
subcordate, wider than the prothorax ; seriate-punctate, the interstices closely punctulate, 3, 5, 7, and 9 
sharply costate, the suture also narrowly raised. Beneath densely punctate. Metathoracic episterna 
narrow. Legs moderately long, rather stout ; femora bidentate, the outer tooth small, the inner one 
long and triangular ; tibia rounded on their outer edge. 
Length 6-63, breadth 34-33 millim. (2?)
