CTENODACTYLA DEPRESSA, n. sp.—Species egregia, valde depressa, 
antennarum articulo basali valde elongato. Depressa, nigra, nitida, capite 
thorace et dimidio basali antennarum testaceo-rufis; capite ut in OQ. 
Chevrolatii post oculos rotundato-angustato; thorace elongato, postice via 
angustato, antice paulo rotundato, supra impunctato; elytris punctato- 
striatis, interstitiis paulo convexis, 3° quadri- 5” bi-foveolato ; prothorace 
subtus impunctato ; tarsorum articulis 4—5 rufo-testaceis. 
Long. 5} lin. 1 exempl. 
Beyond the singular elongation of the basal joint of the antennz 
this curious species offers no character to warrant its separation from 
Ctenodactyla. It inhabits the close fitting folds of large aquatic grasses 
in which species of Cephaloleia, and other flattened forms of Hispide, 
lie concealed in great numbers. C. Chevrolatii and puncticollis I always 
found within the sheathing bases of leaves of Indian corn in plantations.

LEPTOTRACHELUS CRUCIATUS, n. sp.—Ab omnibus speciebus adhue 
descriptis differt corpore haud lineart, elytris oblongo-ovatis. Testaceo- 
rufus, elytris fascia basali alteraque ultra medium (ad suturam postice 
dilatata) per lineam suturalem conjunctis fuscis; capite postice recte 
angustato, thorace breviter oblongo, lateribus antice paululum rotundatis, 
angulis posticis acutis, prope angulos punctato; elytris bast latis, rectis, 
pone medium rotundato-dilatatis, supra fortiter punctato-striatis, interstitirs 
convewis, 3° quadri -5” wni-foveolato; tarsis latioribus, robustioribus, articulo 
4° lobis elongato-ovatis. Long. 43 ln. 1 exempl. 
Differs from all previously described species in its ovate form, 
especially of the elytra, and in the shorter and broader tarsi. The 
claws, mentum, and other parts are, however, formed precisely as in 
Leptotrachelus ; and it possesses also a characteristic feature, hitherto 
omitted in descriptions of this genus, namely, an acute wedge-shaped 
projection of the prosternal process, on a lower plane than the usual | 
apex of that organ.

LEPTOTRACHELUS BIFASCIATUS, n. sp.— Precedent valde affinis, 
differt elytris fasciis dwabus nigris per suturam haud conjunctis. Hlonxgato- 
ovatus, testaceo-rufus, nitidus; thorace oblongo, lateribus antice leviter rotun- 
datis, postice utrinque punctato, disco glaberrimo, angulis posticis rectis ; * 
elytris oblongo-ovatis, punctato-striatis, fascia basali, alteraque ultra medium 
ad suturam paulo dilatata, nigris. Long. 5 lin. 1 exempl.
