4, Chitalia dubia. 
Fusco-rufa, nitida, parum dense sed distincte pubescens, parum punctata; antennis crassiusculis, articulis 
penultimis transversis; prothorace subcordato, medio late profundeque sulcato; scutello canaliculato ; 
elytris quam thorax longioribus, perparum punctatis, tenuiter pubescentibus; abdominis segmentis 1°-3™ 
basi transversim depressis et crenatis; pedibus testaceis. 
Long. 24 millim. 
Hab. Guatemala, Guatemala city, San Gerdénimo, Capetillo, Rio Naranjo 450 feet 
(Champion). 
This species is very closely allied to Chitalia crenata; but its individuals are of 
considerably smaller size, and the antenne are less elongate. It varies in colour and 
size in a manner similar to /. crenata; it has the thoracic groove more developed than 
has the larger species; and in certain individuals, probably the males, this depression 
becomes very broad, so as to occupy the larger part of the surface of the prothorax. 
STENAGRIA. 
Prosternum totum corneum, ante coxas magnum. ‘Tarsi anteriores 4-, intermedii et posteriores 5-articulati. 
This genus, closely allied to Malagria, is distinguished by the much larger antecoxal 
portion of the prosternum ; this development is accompanied by a greater elongation of 
the anterior part of the pronotum ; and the prothorax above thus approximates in form 
to the oval; the supracoxal part is not separated by any raised line from the antecoxal 
part, but is strongly reflexed, so that it assumes a direction nearly at right angles to the 
plane of the anterior piece; the postcoxal piece is very large, and so completely 
amalgamated with the supracoxal piece that the line of junction between the two cannot 
be detected. The genus appears to be the most highly developed form of the Falagria 
group of genera; and the prosternal characters are accompanied by other, slighter 
characters which give to the species of the genus a facies by which they may readily 
be identified. ‘The head is rounded behind, is borne on a very slender neck, and is 
much detached from the prothorax; the slender prothorax is channelled along the 
middle, and the shoulders of the after-body are quite free, there being great capacity 
for motion at the articulation between the pro- and the mesothorax. The hind body is 
distinctly narrowed at the base. The mesosternum is produced in the middle between 
the coxe, much as in Falagria; the side pieces of the metasternum are very broad 
behind. The legs are remarkably elongate and slender; the basal joint of the slender 
filiform hind foot is very long, being fully equal in length to the following three 
together. 
In addition to the species here enumerated, the genus will contain, as I have already 
remarked, several others previously described as Halagrie, but is foreign to Europe, 
where its nearest ally appears to be Hchidnoglossa, Woll. I am not acquainted with 
any North-American representative of the genus; but I think it probable from the 
description that Falagria cingulata, Lec., belongs to it.
