EROTYLUS. 149 



Erotylus. 



Fah. Syst. But. 123 (1775) {fyp. gigantcus, Fab.). 



This genus seems to me somcwLat difficult to characterize, as 

 Lacordaire has comprised in it species with the rostrum parallel 

 and coarctate. All the species are of tolerably large size, and 

 have the elytra more or less visibly gemellate punctate-striate. 



A. Rostro quadrangular!, elytris plus minusvc regulariter 

 punctato-striatis. 



Erotylus histrio. 



Erotylus hlstrio, Fah. Mant. 91 (1787). - - - 



, Lac. Erot. 419. 



Brazil. 



Kecognizable by the impressed punctures being black on the 

 yellow fasciae; 1st ventral segment with an impressed pilose dot. 



Erotylus Chevrolatii. 



Erotylus Chevrolatii, Lac. Erot. 421. 



Brazil, Minas Geraes, Sta. Catharina. 



Differs from E. histrio by the deep coarse punctures of the 

 elytra, smaller size, etc. The type is an immature specimen with 

 the yellow markings sub-confluent : ^ dotted ; abdomen with 

 last segment faintly punctulate. 



Erotylus segrotus. 



Erotylus cegrotus, Lac. Erot. 420. 

 BryaSy Lac. Erot. 424. 



Brazil. 



Yery near E. Chevrolatii, but with the punctuation more 

 obsolete, and the yellow fasciae filled uji with brown instead of 

 black : <5 dotted ; abdomen punctulate as in E. Chevrolatii. 



E. Dryas is unquestionably only an immature state. 



Erotylus histrionicus. 



Erotylus histrioiiicus, Bup. Erot. 8, T. i. f. 4. 

 , Lac. Erot. 422. 



Brazil. 



Differs from E. histrio by its nari'ow boat-like shape ; the 

 yellow markings crowd the elytiu all over, leaving no decided 

 black fascia. Abdomen punctulate beneath.
