TRACHELIZUS. 31 
B. Prosternum of male with a minute fovea in the middle of the anterior part. 
(Species 21-23.) 
21. Trachelizus laticollis, sp. n. 
Brunneus, sat nitidus, supra subplanatus ; thorace fortiter punctato; elytris pone medium nigro-bimaculatis, 
seriatim regulariter punctatis, summa basi regulosis. 
Long. 13 millim. 
Hab. Guatemata, Teleman in Vera Paz (Champion). 
_ Antenne rather elongate; club elongate, but scarcely at all broader than the 
‘preceding joints. Impression on the vertex very elongate, not limited in front, but 
prolonged forwards beyond the eyes; prorostrum deeply and broadly sulcate. ‘Thorax 
large, the anterior part closely punctured even in the middle, the sides of this part 
with some vague wrinkles, the posterior of which causes the thorax to appear 
subconstricted near the front; the median channel extends very near to the front 
margin, but its anterior part is subobsolete; the sides and upper part of the thorax 
rather coarsely punctured. Elytra elongate, with very regular series of deep punctures. 
Serial punctures of the underside of the head and rostrum distinct, separated, not by 
a carina, but a broad interval, which, though dull on its broad part, does not appear 
velvety. Prosternum shining, in the middle (in the male) witha minute fovea, Breast 
and abdomen almost unsulcate. Apices of elytra simple. 
Only one example was obtained of this insect; it is unfortunately much mutilated, 
but is, I think, distinct from the following, which, however, it greatly resembles. 
22. Trachelizus ducalis, sp.n. (Tab. I. fig. 25.) 
Rufo-brunneus, nitidus, supra subplanatus; thorace elongato, anterius regulariter angustato, ad marginem 
anteriorem densius punctato ; elytris pone medium nigro-notatis, regulariter seriatim fortiter punctatis. 
Long. 16 millim. 
Hab. Guatemata, Cerro Zunil (Champion). 
This fine Brenthid is remarkable by the extreme elongation of the impression on the 
vertex, which, becoming gradually narrower, is prolonged on to the rostrum, disap- 
pearing almost entirely halfway between the eyes and the antenne. The prorostrum 
is very deeply and broadly sulcate. The thorax is much narrowed in front, and very 
distinctly punctate. The elytra have quite regular series of very large punctures, the 
intervals being flat. The characters of the under surface are those of 7. laticollis, 
except that the under surface of the head is even less dull. 
One example. 
93. Trachelizus prolixus, sp. n. (Tab. I. figg. 26, ¢; 26a, head and 
rostrum, @ .) 
Subcylindricus, elongatus, ferrugineus, nitidus, elytris pone medium nigro-notatis ; prothorace crebre punctato, 
elongato ; elytris seriatim fortiter punctatis. 
Long. 8-16 millim.
