10 RHYNCHOPHORA. 
22. Attelabus longiclava, sp. n. 
2. Rufus, nitidus, rostro, antennis, pedibus elytrorumque parte posteriore nigris; antennarum clava gracili, 
perelongata:; prothorace transverso, leviter insequali, parce punctato; elytris brevibus, ad basin sub- 
tiliter striatis, pone scutellum obsolete depresso. 
Long. 4 millim. 
Hab. Panama, Bugaba 1000 feet (Champion). 
Although we have only a single female example in a bad state of preservation, and it 
is closely allied to both A. sedatus and A. brevicollis, there is no doubt it is quite distinct 
from either. Itis at once distinguished from A. brevicollis by the eyes being separated 
only by a smooth carina instead of a broad rugose space; from A. sedatus it may be 
identified by the more approximate eyes, and by the shorter, more uneven, less smooth 
thorax. The club of the antenna is remarkably elongate and slender, and on this account 
the species is best placed near A. sedatus. The eyes are only very slightly convex; the 
thorax is foveolate on each side of the middle, sparingly punctate ; the scutellum is very 
broad ; and the elytra are very feebly depressed behind the scutellum, striate at the 
base and towards the suture, elsewhere with series of very fine punctures. 
The dark colour of the legs and antenne may possibly be due to decomposition, 
but the black posterior part of the wing-cases is no doubt natural. 
23. Attelabus ligulatus, sp. n. 
Sanguineo-rufus, nudus, nitidus; oculis convexis ; prothorace transverso, inequali; elytris ad latera utrinque 
angulatim prominulis, pone scutellum anguste impressis, striatis, striis ad basin sat profundis. 
Long. 47 millim. 
Hab. Mexico, Playa Vicente (Sallé, Hoge), Cordova (Sallé); GuatemaLa, Coban 
(Conradt); Panama, Bugaba (Champion). 
In this species the male exhibits characters analogous to those of A. lesicollis, and 
possesses a further remarkable peculiarity, inasmuch as the two tubercles of the under 
surface of the rostrum are largely developed and amalgamated together, forming a 
ligula divided at the extremity only, and projecting considerably beyond the mouth. 
The head is deeply bisulcate between the prominent eyes, rugose in the female, 
but little sculptured in the male; the vertex in the male is very elongate and 
curvate, and is transversely and longitudinally impressed. The thorax is short, 
sparingly and feebly punctured in the female, almost impunctate in the male; but in 
this sex it bears two longitudinal impressions on the disc, and the oblique lateral 
impressions are deeper than in the female. The elytra have an angular projection on 
each side just behind the shoulders, and the inner strie are very deep at the base. 
The scutellum is very broad and short. The club of the antenne is moderately long. 
The front femora in the male are angulate beneath; in the female they are formed as 
in the corresponding sex of the allied species. 
Four examples. The only specimen found at Bugaba is a female. :
