136 Mr. G. C. Champion's Revision of the Mexican 



This species must be nearly related to B. {Malthinus) 

 chevrolati, Guer., from Brazil, to judge from the author's 

 figure of the latter. The abdomen is entirely testaceous, 

 and the emarginate penultimate dorsal segment of the male 

 has the outer angles deflexed. The head is more narrowed 

 behind the eyes than in B. abdominalis and the eyes them- 

 selves are more convex. The genital armature is very 

 different from that of the other two species of the genus 

 here enumerated, see Plate VII, fig. 44.

 Lacordaire, Gen. Coleopt. iv, p. 362 (1857) {nee 

 Leconte). 



The type, ^, of this genus L. torticornis* Kies., from 

 Venezuela, has the antennae peculiarly formed, the terminal 

 joint of the maxillary palpi long and cultriform, the head 

 broad, and narrowed posteriorly, the eyes prominent and 

 widely separated, the posterior coxae much enlarged, the 

 tarsal claws simple, the penultimate dorsal segment of 

 the abdomen broadly emarginate, leaving a small terminal 

 segment exposed, the seventh ventral segment cleft, and 

 the genital armature asymmetric and greatly developed. 

 The female, subsequently described by Lacordaire, has 

 slender filiform antennae, with a much smaller basal joint 

 and the second and third joints more elongate. There is 

 a pair of this species in the Oxford Museum, apparently 

 received from the traveller A. Salle, ticketed " Guatemala " ; 

 but there must have been some mistake made in labelling, 

 due to Salle having visited both Venezuela and Guatemala. 

 It is very doubtful whether the various S. American and 

 Antillean Lobeti described by Pic in 1906 are really 

 congeneric with L. torticornis.] 



PsEUDOLOBETUs, n. gen. 



Head broad, obliquely narrowed behind the eyes, the latter 

 prominent and widely separated; apical joint of the labial palpi 

 stout, securiform, that of the maxillary pair long and cultriform; 

 mandibles sharply toothed towards the apex within; antennae 



* This name was incorrectly printed torticollis in the diagnosis of 

 the species, but it was correctly given on pp. 322, 323 of Kiesen- 

 wetter's work.
