248 NEOTROPICAL PSELAPHIDAE 



6. Intermediate trochanters bearing at middle a tubercle which in turn 



bears a trichome of long setae ; posterior trochanters bearing at mid- 

 dle a short tubercle which bears in turn a trichome of long setae, 

 and apically these trochanters are recurved with the apex in the form 



of a small hook with a very sharp point; 3.2 mm hiarmatus 



Intermediate trochanters bearing at middle a small tooth 7 



7. Posterior trochanters with the apex extended in a long, strong, com- 



pressed spine which is recurved and truncate germari 



Posterior trochanters bearing at apical third a hook-shaped spine, this 

 spine is broad, flattened, slightly spiral with a truncate apex and 

 bearing near base a trichome regius 



Species of Itetiaus may be listed as follows: 



hiarmatus (Raffray). 1897. Bahia, Brazil. {Batrisus) 

 germari (Aube). 1844. New Friburg, Brazil. (Batrisus) 

 imperialis (Raffray). 1897. Yuracaris, Bolivia. (Batrisus) 

 laeviceps (Raffray). 1897. Yuracaris, Bolivia. (Batrisus) 

 longispina (Raffray). 1897. Minas Geraes, Brazil. (Batrisus) 

 princeps (Reitter). 1882. Petropolis, New Friburg, Constancia, and 

 Theresopolis, Brazil. (Syrbatus) (Genotype) 

 regius (Raffray). 1896. Caraca, Minas Geraes, Brazil. (Batrisus) 

 semipunctatus Raffray. 1908 and 1909. Serra de Baturite, Ceara, 

 Brazil. (First species described as Iteticus) 



At this place in the tribe Batrisini a few words may be said regarding 

 three very puzzling species: 



Schaufuss described Batrisus asteriscus from Bogota, Colombia in 1887. 

 Raffray (1897) examined and reported on the type of this insect, placing it 

 with doubt in the neotropical species of Batrisus. In this paper he felt that 

 asteriscus was quite apart from other neotropical members of the genus 

 since it had three cephalic sulci and five pronotal sulci, placing it near 

 Batrisus quinquesulcatus Raffray of Singapore. In 1904 Raffray erected Iteticus 

 for all of the neotropical Batrisus listed in his 1897 paper, save asteriscus. 

 The type of asteriscus was imperfect, but Raffray concluded that it could not 

 be Iteticus as this genus, among other things, lacks any trace of a median 

 longitudinal sulcus. In the structure of the abdominal margins asteriscus is 

 Batrisodes, unknown in the neotropics. If asteriscus turns out to be in the 

 latter genus, it becomes very important as a link with Iteticus, for reasons 

 given above, but since the species has not been recorded since 1887, little more 

 can be said now save to point out its affinities with Group 40 of Batrisodes 

 holding quinquesulcatus Raffray of Singapore and Sumatra, and spinicollis 

 Motschulsky of Ceylon ! This highly doubtful assignment is doubly questioned 

 by Raffray (1908) and I feel that there is insufficient data to cita Batrisodes 

 as present in the neotropical region on the assumption that asteriscus might 

 belong to the genus.
