LEPTOCOMETES. 
Generi Anisopodo affinis, at differt inter alia thoracis tuberculis lateralibus medianis. Corpus elongatum, 
gracile, parum convexum. Caput antice verticale, fronte brevi; oculi magni; vertex inter antennas valde 
concava. Antenne (¢)corpore duplo longiores, basin versus infra longe et sparse setose ; scapo elongato, 
subtus vix flexuoso; articulis 3°-11™ longitudine fere equalibus, scapo vix brevioribus. Thorax subquadratus, 
dorso antico grosse bituberculato, tuberculis lateralibus grossis fere medianis apice spina acuta armatis. 
Elytra elongata, postice gradatim attenuata, epipleuris verticalibus haud carinatis, apice sinuato-truncata 
bidentata, tota superficie longe erecte setosa, tuberculis centro-basalibus obtusis. Pedes elongati; femora 
clavata, longe pedunculata ; tarsi postici graciles, articulo primo quam duo sequentes longiore. Prosternum 
angustissimum ; mesosternum angustum ; coxe globose, paullo exstantes. 
The slender form, voluminous lower lobe of the eyes, and narrow pro- and mesosterna 
indicate the close affinity of this genus to Anisopodus, from which the thoracic tubercles 
and long hairy elytra amply distinguish it. The form of the lateral tubercles of the 
thorax differs from that of the preceding genera, the apex of the protuberance forming 
a retrocurved point as in Leiopus. Besides the two large obtuse tubercles on the anterior 
part of the disk of the thorax, there are two others, much less elevated, on the 
posterior part. 
1. Leptocometes hispidus. 
Olivaceo-griseus, elytris macula magna obliqua laterali postmediana atro-fusca; antennarum articulis basi, 
femoribus basi, tibiis medio articuloque primo tarsorum flavo-testaceis. 
Long. 5 lin. o. 
Hab. Mexico, Cordova (Sallé). 
The long, erect, and rather fine sete of the elytra are implanted each in a puncture, 
which, along the suture, is accompanied by an elevated granule. The elytra are 
depressed behind and on the outer sides of the centro-basal elevations; and the apical 
truncature is slightly oblique, sinuate, with the exterior angle considerably prolonged 
and dentiform. 
OZIN EUS. 
Ozineus, Bates, Ann. & Mag. Nat. Hist. ser. 3, xu. p. 278 (1863). 
With this genus commences the series of Acanthocinini allied to Leiopus, in which 
the lateral armature of the thorax is more or less approximated to the hind angles, and 
presents the form of an oblique spine. 
Eight species of Ozineus have been described, all from Tropical America.
