NEOBROTICA AXD RELATED GENERA — BLAKE 335 



Eucerotoma; surface alutaceous and with scattered fine punctation; 

 pale yellow with a broad median piceous vitta extending the length 

 of pronotum and narrowed at the base. Scutellum dark. Each 

 elytron with 8 distinct costae and the intervals geminate striate 

 punctate ; black with faint purplish lustre, in the middle of each elytron 

 a large pale spot not reaching the suture or margin and another pale 

 area along the apical margin to the apical curve. Body beneath with 

 the abdomen and most of the breast dark, but the forepart of the breast 

 pale, the mesothorax dark in the middle. Legs with the femora pale 

 except for a dark streak on the apex, the tibiae and tarsi mostly 

 dark. Front tibiae of the male and the first tarsal joint enlarged. 

 Length 5-6 mm. 



Type, male; one paratype, female; both in Zoologische Sammlung 

 des Bayerischen Staates, Munich, Germany, from Guayaramerin, 150 

 m., Beni Gebiet, Bolivia, collected by W. Forster, 1954. 



Remarks : Bechyne has labelled this as a new species of Eucerotoma 

 and attached the specific name irritans to a specimen in the zoo- 

 logical collection at Munich. I have been unable to find that the 

 name has ever been published. It does not belong to the genus 

 Eucerotoma as it does not have the sexual characteristics shown in 

 that genus, consisting of the excavate face and enlarged third and 

 fourth antennal joints of the male. Neither do the elytral costae 

 resemble the much stronger costae of Eucerotoraa, and the sulcus 

 across the pronotum has none of the intagho-like carved impression 

 of that genus. It belongs rather with the gi"oup found mainly in 

 Peru and Bohvia with a depressed lower front of the head not dif- 

 fering in the sexes.
