Sept.-Dec, igiS.] LeNG : CHANGES IN LiST OF CoLEOPTERA. 205 



The name Acolpus Jayne, 1882, is very close to Acolpos Brandt 

 (Act. Acad. Pet., 1835), but, if the original spelling of the latter is 

 followed, no change seems necessary. 



Acritus atonius Lee. described from Cuba, occurs at Lake Worth 

 and Biscayne Bay, Florida. There are Florida specimens in the 

 Blanchard collection as well as those in the Nat. Mus. 



Hetccr'ms helence Mann, described from Mexico, occurs also at 

 several places in Arizona. H. cannistriatus Lewis (teste W. M. 

 Mann) is a synonym of H. blanchardi Leconte. 



Carpophilus (subgenus Urophorits) Immcralis Murray known 

 from Philippines, Seychelles, Java and Africa, has been introduced 

 at Oneco. Florida. As it can live in decaying fruit it is liable to be 

 spread further by commerce. 



Coluocera maderce Woll. This species, described from Madeira, 

 has been found in Brazil, Trinidad and Haiti and is very likely to 

 occur in Florida. It is nearly cosmopolitan, having reached India as 

 well as the countries named. 



Eubrianax Kies. {=Placoiiyc]ia Horn) has a larva superficially 

 like that of Psephenus, as I was informed by Dr. Schwarz. Pro- 

 fessor Wickham, who was present, added that the adult occurs on 

 stones in water like Psephenus. The genus should perhaps be trans- 

 ferred from Dascillidse to Psephenidse. 



Cryptohypnus planatus Lee, 1866, is preoccupied by C. planatus 

 Esch., 1829, and may be changed to C. lecontci n.m. 



Melanotus longicornis Blatchley, 191 o, is preoccupied by -1/. loiigi- 

 coniis Cand, i860, and may be called il/. hlatchleyi n.m. 



Ludius (Corymbites) elegans Cand., 1888, is preoccupied by L. 

 elegans Kby., 1837, and may be called L. candesei n.m. 



Octinodes Cand., 1863, should be used for the American species 

 heretofore called Plastocerus. The type and only species of Plas- 

 tocerus Schaum, 1852, is angulosus Germ, from Asia Minor. Dr. 

 Leconte sent an American species which he believed belonged to that 

 genus to Schaum and, upon receiving his confirmatory reply, described 

 in 1853 Plastocerus schainni. This species is not congeneric with the 

 Asiatic species but apparently belongs to the genus erected by Can- 

 deze in 1863, as do several others from Central and South America. 

 The type of this genus is Octinodes capillatus from Venezuela. Eu- 

 ropean authors have incorrectly treated Plastocerus as Dr. Leconte's
