8 RHYNCHOPHORA. 
17. Attelabus conicollis, sp.n. (Tab. I. fig. 7, 2.) 
Sanguineo-rufus, nitidus; prothorace squali, subconico, parce obsoleteque punctato; elytris subquadratis, 
pone scutellum vix impressis, punctorum seriebus tantum ad basin conspicuis. 
Long., ¢, 7 millim. 
Hab. Mexico, San Andres Tuxtla (Sallé), Teapa in Tabasco (H. H. Smith); British 
Honpuras, R. Hondo (Blancaneaua); GuateMALA, El Reposo (Champion), Panzos 
(Conradt) ; Nicaracua, Chontales (Belt, Janson). 
Head rather broadly but vaguely sulcate behind the eyes. Thorax with the usual 
curved or angulate transverse sulcus very obsolete. Scutellum very broad. LElytra less 
shining than the thorax, the punctures of the series very fine except at the base; the 
depression behind the scutellum slight, and not extending so far outwards as the 
scutellum itself. In the male the thorax, head, rostrum, and front legs are longer 
than in the female, and the rostrum bears near the extremity beneath two projecting 
acute tubercles ; the antenne are longer in the male, but the club is elongate in each of 
the sexes, and scarcely shorter in the female. 
Our figure is taken from a female found at Chontales. 
18. Attelabus sedatus, sp. n. 
Sanguineo-rufus, nitidus, nudus; prothorace transversim subconico, impunctato; elytris subquadratis, pone 
scutellum vix impressis, ad basin seriatim punctatis, preterea fere impunctatis ; antennarum clava elon- 
gata, laxe articulata. 
Long. 8 millim. 
Hab. Mexico, Toxpam, Tuxtla (Sal/é), Oaxaca, Paso del Macho (Hoge); GuaTEMALA, 
Yzabal (Sad/é). 
One of the smallest species of the genus, and one in which the sculpture of the upper 
surface is the least distinct. Very closely allied to A. conicollis, but not half the size of 
the smallest individuals I have seen of that species. The thorax is remarkably smooth 
and even, there being, however, a slight depression or constriction across it behind the 
front margin. ‘The series of punctures on the elytra are distinct only at the base and 
near the scutellum. In the male the club of the antenne is slender and elongate, its 
first and second joints being each longer than broad ; the rostrum is furnished with two 
acute tubercles at the apex beneath; the head is not sulcate behind the eyes; and the 
front tibize are slender and elongate, and armed with a single mucro at the apex. The 
female differs in the shorter, bimucronate tibie, and the absence of the denticles on 
the rostrum. 
Eight examples. 
19. Attelabus angulipennis, sp. n. 
Brevis, testaceus ; oculis parum distantibus; prothorace conico-transverso, impunctato ; elytris ad latera pone 
humeros angulatis, ad basin subtiliter striato-punctatis, 
Long. 3 millim. 
Hab. GUATEMALA (Champion).
