the Coleopterous Family Erotylidce. (149) 525 



Erotylus. 



Fah. Syst. Ent 123 (1775) {typ. giganteus, Fab.). 



This genus seems to me somewhat difficult to characterize, as 

 Lacordaire has comprised in it species with the rostrum parallel 

 and coai'ctate. All the species are of tolerably large size, and 

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



A. Rostro quadrangulari, elytris plus minusve regulariter 

 punctato-striatis. 



Erotylus histrio. 



Erotylus histrio, Fah. Mant. 91 (1787). 



, Lac. Erot. 419. 



Brazil. 



Recognizable 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 mai'kings sub-confluent : $ dotted ; abdomen with 

 last segment faintly punctulate. 



Erotylus seg'rotus. 



Erotylus oigrotus, Lac. Erot. 420. 

 Dry as, Lac. Erot. 424. 



Brazil. - 



Very near E. Chevrolatii, but with the punctuation more 

 obsolete, and the yellow fascise filled up with brown instead of 

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



E. Dryas is u.nquestionably only an immature state. 



Erotylus histrionicus. 



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



, Lac. Erot. 422. 



Brazil, 



Differs from E. histrio by its narrow boat-like shape ; the 

 yellow markings crowd the elytra all over, leaving no decided 

 black fascia. Abdomen punctulate beneath.
