EUBULUS. 
Eubulus, Kirsch, Berl. ent. Zeitschr. 1869, p. 200. 
Cryptorhynchus (Division A-a*), Leconte, Proc. Am. Phil. Soc. xv. p. 250. 
The characters given by Kirsch would have to be emended to include the numerous 
species here described under Eubulus. Some of those placed at the head of the genus 
migat be almost equally well referred to Zascelis, and the small forms placed towards 
the end have a very different facies. ‘The five enumerated by Kirsch, of which Crypto- 
rhynchus orthomasticus, Germ., may be taken as the type, are of large size, and they 
all occur within our limits. 
The Central-American forms agree in the following characters :— 
Elytra narrowed from, or from a little below, the base, with the alternate interstices, and sometimes the others 
also, costate, the humeri either prominent or forming an almost continuous outline with the sides of the 
prothorax. Rostrum reaching as far as or beyond the middle of the intermediate coxe, in the typical 
forms slightly impinging on the anterior margin of the metasternum. Legs similar in the two sexes ; 
femora often bidentate or at least with indications of a second tooth, in some species unidentate ; tibie 
rounded or angulate at the base externally, more or less distinctly carinate on the outer edge, the carina 
(when prominent) straight and uninterrupted. Mesosternal excavation oblong or horseshoe-shaped. 
Ventral segments 2-4 subequal in length, or 2 a little shorter than 3, the first suture arched or straight. 
Antenne with an ovate or oblong club; funiculus with joint 2 elongated in the typicai forms. 
The various species may be grouped thus :— 
A. Tibiz rounded at the base externally; head usually carinate above the eyes. 
a. Elytra with all the interstices costate; femora bi- or unidentate ; joint 2 of 
the funiculus not longer than 1; body oblong-ovate or ovate, Baridiiform. Species 1-4. 
6. Elytra with the alternate interstices costate, at least towards the apex. 
a’. Prothorax with the flanks in great part or wholly ochreous or white, the 
disc sometimes maculate in the middle at the base; the head in a few 
species albo-maculate in front ; femora bi- or unidentate . , : . . Species 5-13. 
6’. Prothorax with the flanks reticulate with white, its upper surface and the 
basal portion of the elytra with a very large, common, blackish or 
rusty-red patch bordered by a whitish line. 
b"'. Body rhomboidal, the discoidal patch uniformly blackish ; i ies elongate, 
femora bidentate . . . . Species 14. 
‘. Body subovate, the discoidal patch sty orange in the middle ; 
legs shorter, femora unidentate . . . Species 15. 
. Prothorax with the flanks streaked with whitish - in front, the elytra with 
a similarly-coloured oblique streak or a few scattered spots; femora 
unidentate. . .. . see ee ew eww ww. ~Species 16, 17. 
a. Prothorax and elytra each with a black annulus; femora didentate . . Species 18. 
. Prothorax with a black eye-like spot on the disc bordered by a fulvous 
line ; legs short and stout, femora unidentate; body ovate . . . . Species 19. 
f’. Prothorax and elytra with a common subquadrate black patch: body
