556 RHYNCHOPHORA. 
this species from all the others of the group here described. The seventh dorsal 
segment of the abdomen is quadridentate at the apex, as in &. aspericollis. 
This species has the facies of a large Cionus. There is a form very like it from Para 
in the British Museum. 
20. Eubulus nigrosignatus, sp.n. (Tab. XXVIU. figg. 19, 19 a.) 
Oblong-elliptic, piceous, the antenne: ferruginous; thickly clothed with rather coarse fulvous scales, with a few 
cinereous scales intermixed, the prothorax and elytra with a large, common, rounded-subquadrate, velvety 
black patch on the disc, the upper surface also set with very short, scattered, erect sete ; the vestiture of 
the under surface and legs fulvous. Head rugulosely punctate, with indications of a faint oblique ridge 
above each of the eyes, the latter somewhat narrowly separated; rostrum curved, nearly reaching the 
metasternum, rugulosely punctate and carinate at the base, the apical half finely punctate, the antenne 
inserted at about the middle, joint 2 of the funiculus much shorter than 1, the club ovate. Prothorax 
transverse, arcuately narrowing from near the base ; densely punctate and carinate. Scutellum rounded. 
Elytra oval, at the sides forming an almost continuous outline with the prothorax, produced at the apex ; 
seriate-punctate, the interstices punctulate, 3, 5, 7, and 9 narrowly costate. Beneath dull, densely 
punctate. Legs rather short, stout, the tarsi more slender; femora subclavate, sharply unidentate, and 
with indications of a very small additional tooth ; tibie somewhat curved externally. 
Length 4, breadth 1? millim. 
Hab. Panama, Caldera in Chiriqui (Champion). 
One specimen. An isolated form, differing from all its allies in the shape and position 
of the velvety-black patch on the disc, as well as in its oblong, elliptic shape, &e. 
21. Eubulus nimbatus, sp.n. (Tab. XXVII. figg. 20, 20a, 2; 21, ¢.) 
Ovate, black, the antenne and the tips of the tarsi ferruginous; the depressed frontal space, a spot on the 
basal lobe of the prothorax, one on the mesothoracic epimera, and another at the apex of the metathoracic 
episterna, clothed with white, ochreous, or rosy-red scales, the prothorax with a few scattered, coarse, 
white and fulvous scales; the elytra somewhat thickly clothed with small brown scales, with a few 
whitish scales intermixed; the vestiture of the under surface and legs rather sparse, the femora more or 
less annulate towards the apex. Head rugulosely punctate, the trapezoidal frontal depression limited by 
a curved or oblique carina above the eyes, which are very large and subcontiguous ; rostrum strongly 
curved, reaching the front of the metasternum, widened, rugosely punctate, and carinate at the base, and 
almost smooth thence to the tip, the antenne inserted towards the base, the funiculus slender, joints 1 
and 2 subequal in length, the club stout, ovate. Prothorax short, arcuately narrowing from the base, 
feebly constricted in front; coarsely, confluently punctate, and sharply carinate to the apex. Scutellum 
oblong, convex, smooth, the cavity deep. Elytra at the sides forming an almost continuous outline 
with the prothorax; shining, seriate-punctate, the interstices punctulate, 3, 5, 7, and 9 very sharply 
costate. Beneath dull, closely, shallowly punctate; metasternum short ; first ventral segment depressed 
down the middle and sublamellate at the apex in the ¢. Legs short and stout; femora sharply 
unidentate, the anterior pair with a minute additional tooth; tibize rounded at the base externally. 
Length 33-44, breadth 14-23 millim. (¢ Q.) 
Hab. Panama, Bugaba (Champion). 
Found in abundance at Bugaba. Separable from the other small forms with a dense 
whitish frontal patch by its regularly oval shape, the two white spots at the sides of 
the body beneath, the cluster of coarse white scales on the median lobe of the prothorax, 
the complete carina of the latter, the absence of sete, &c.
