minor characters, in addition to the two mentioned above. The elytra are not so 
abbreviate; the rostrum is rather longer and not at all attenuate in front; the meta- 
sternum, though quite small, is not so short; and the posterior tibie have a large 
truncature outside the corbels, the truncature being densely setose. ‘The scrobes are 
quite lateral and remarkably definite, extending quite to the underside of the anterior 
part of the eye, which they touch for some distance. The impressions on the under 
surface of the rostrum are remarkably deep. There is a feeble constriction of the 
vertex immediately behind the eyes. 
1. Maseorhynchus hondurensis, sp. n. (Tab. VI. fig. 12, 2.) 
Convexus, griseo-squamosus et setosus ; prothorace convexo, squali, anterius rotundato-angustato. 
Long. 6-9 millim. 
Hab. British Honpuras, Belize, R. Sarstoon, R. Hondo (Blancaneauz). 
Var. Squamulis pallide subviridescentibus. 
Hab. Guatemaua, Panzos in Vera Paz (Champion). 
Rostrum parallel, its anterior surface nearly flat, being scarcely at all impressed 
along the middle; eyes very prominent ; first and second joints of funiculus elongate, 
the latter very slightly the longer. Thorax large, curvate at the sides and greatly 
narrowed in front, sparsely punctate, the sculpture quite concealed by the squamosity. 
Elytra truncate at the base, with a very obscure elevation forming a sort of basal 
margin; covered with densely crowded scales which are loosely fixed to the surface 
and very easily removed, also with numerous short, coarse, pallid, subdepressed sete ; 
bearing regular series of large punctures that are much obscured by the scales. Six 
specimens. 
The male of this species is apparently considerably smaller and more slender than 
the female. Only one example of the elegant variety from Guatemala was obtained ; 
it may possibly prove to belong to another species, as the scales on the elytra are larger 
in size and not so crowded together, as well as different in colour.

Mestorus, Schiénherr, Gen. Cure. v. p. 910 (1889). 
This genus was established for a single species from Mexico ; to this, two others 
from the same country are now added. All appear to be very rare insects.
