FALAGRIA.—CHITALIA. 235 
Hab. Guatemaua, Zapote (Champion). 
Antenne rather stout; the four basal joints bright yellow, first and second joints 
subequal in length, third stout, much shorter, fourth rather small, subquadrate, the 
seventh to tenth rather strongly transverse. Head broad, nearly as wide as the elytra, 
truncate behind, the upper surface coarsely punctate in front. Thorax much narrowed 
behind, with a very distinct channel along the middle; the channel is not placed in a de- 
pression, extends the whole length, and is subfoveolate in front of the scutellum. This 
latter is punctate, but without carine or channels. Elytraa little longer than the thorax, 
not standing out much from the body, finely punctate, the punctuation denser at the 
base round the scutellum. Hind body subparallel, very little narrowed at the base, 
finely punctate, the transverse depressions on the basal segments very little developed. 
Only two individuals have been found of this species. I am not able to discover 
exactly the structure of the prosternum ; but the posterior portion is evidently corneous. 
CHITALIA. 
Genus Falagrie persimile, sed mesosterni margine posteriore libero, in medio inter coxas intermedias haud 
producto. | 
Besides the four species here ascribed to this genus, it will probably comprise some 
of the North-American species at present referred to Yalagria. The prosternum in 
these insects is, as in Malagria, entirely corneous behind. In many other characters the 
genus also agrees with Falagria ; but the mesosternum has its hind margin approximating 
somewhat to the structure we find in Awtalia, its hind margin being on a rather different 
level to the pieces behind it, and thus appearing free, while in the middle it is not pro- 
duced backwards between the coxe, but forms only a very obtuse angle. 
1. Chitalia crenata. 
Fusco-rufa, nitida, parum dense sed distincte pubescens, parum punctata; antennis crassiusculis, articulis 
penultimis vix transversis ; prothorace subcordato, medio profunde sulcato; scutello canaliculato; elytris 
quam thorax longioribus, perparum punctatis, tenuiter pubescentibus; abdominis segmentis 1°-3™ basi 
transversim depressa et crenata; pedibus testaceis. 
Long. 33 millim. . 
Hab. Muxico, Jalapa (Flohr), Guanajuato, Cordova, Toxpam (Sallé); GuATEMALA, 
Guatemala city, San Gerénimo, Capetillo, Coban and Senahu (Champion). 
The head is short and broad, subtruncate behind, usually darker than the other 
parts, of a shining black or brassy black colour, not punctate. The antenne are rather 
long and stout, variable in colour from nearly red to nearly fuscous, the basal and apical 
joints being somewhat paler than the others. ‘The thorax is rather broader than long, 
rounded in front, very greatly narrowed behind, and is traversed by an extremely deep 
longitudinal groove. The transverse depressions on the basal segments of the hind body 
are deep, and their crenulation is very distinct.
