CONOTRACHELUS. 309 
81. Conotrachelus albosignatus, sp. n. (Lab. XVIII. fige. 26, 26 a.) 
Subovate, slightly shining, nigro-piceous, the antennze and the tips of the tarsi obscure ferruginous; the 
vestiture rather close, coarse, brownish or fulvous, the prothorax with a dense, oblique, sinuous, white 
line on each side of the disc, continued along the base of each elytron to the humerus, the two lines 
nearly meeting in front, and the elytra with a large, common, irregular, transverse, dense white patch 
at some distance before the apex; the clothing of the under surface very sparse and mostly white, that, 
of the legs closer, fulvous and white intermixed, the femora with a whitish or ochreous ring. Head 
closely punctate, transversely depressed in front; rostrum stout, curved, not or very little longer than 
the head and prothorax, rugulosely punctate and obsoletely tricarinate, bare and rather sparsely punctate 
at the tip, the antenne inserted at about one-third from the apex, joint 2 of the funiculus shorter than 1. 
Prothorax rather small, transversely subquadrate, abruptly narrowed and constricted in front, bisinuate 
at the base; densely, somewhat finely punctate, without trace of median carina. Elytra nearly twive as 
wide as the prothorax, obliquely constricted beneath the prominent, obtuse humeri, narrowing from 
the basal fourth; coarsely seriate-punctate, the interstices rugulose, 3, 5, 7, and 9 sharply costate, the 
ridge on 3 and 5 twice, and that on 7 once, abruptly interrupted, the median elevation on 3 greatly raised 
and lamelliform and the subapical one on 5 vertical behind, 10 with a short ridge at the base, its apex 
dentiform. Prosternum with a tubercle behind each anterior coxa. Mesosternum flattened between the 
coxee, sloping in front. Ventral segments very sparsely, finely punctate. Femora clavate, unidentate. 
Tarsal claws with a rather long tooth. 
Length 52-6, breadth 32,-3} millim. (<3 @ ?) 
Hab. Mexico (ex coll. Flohr), Jalapa (Hoge). 
Four specimens, probably including both sexes. Closely allied to C. alboplagiatus, 
as noted above, but with the prosternal prominences smaller, the dense white patch on 
the elytra not reaching the apex, the prothorax relatively narrower and without trace 
of median carina, &c. 
9. Conotrachelus curvidens, sp. n. (Tab. XVIII. figg. 27, 27a; 2746, ante- 
rior leg.) 
Subovate, slightly shining, varying in colour from black to rufo-piceous, the antenns and tarsi more or 
less reddish; the vestiture sparse, ochreous, condensed into a faint sinuous line on each side of the disc 
of the prothorax, a small spot at the hind angles, and a small patch on the humeri in front, the femora 
with indications of a whitish ring. Head densely punctate; rostrum stout, strongly curved, considerably 
longer than the head and prothorax, sharply 5-carinate, thickly punctate at the tip, the antenne inserted 
at from one-third to one-fourth from the apex, joints 1 and 2 of the funiculus subequal in length. 
Prothorax broader than long, constricted and narrowed in front, strongly bisinuate at the base; densely, 
rugulosely punctate. Elytra slightly constricted below the humeri, the sides arcuately converging from 
the basal third to the apex; coarsely seriate-punctate, the interstices rugulose, 3, 5, 7, and 9 sharply 
costate, the ridge on 8 and 5 twice, and that on 7 once, abruptly interrupted. Mesosternum flat between 
the cox, bituberculate in front. Ventral segments shining, sparsely, finely punctate. Femora clavate, 
sharply unidentate, the tooth on the anterior pair long, curved, and outwardly directed, that on the two 
other pairs straight and triangular. Tarsal claws with a short tooth. 
Length 43-53, breadth 23-24 millim. (d.) 
Hab. Guatemata, Senahu, Sinanja, and Sabo in Vera Paz (Champion). 
Nine specimens, perhaps all males, from the dense, forest-clad, Atlantic slope. 
The peculiar shape of the tooth of the anterior femora separates C. curvidens at once 
from C. tridens and other somewhat similar forms.
