Family XLV. BOSTRYCHIDiE. 



Lyctus should be separated as family Lyctidse which includes also 

 * Minthea rugicollis Walker (Lyctopholis foveicollis Reitter), St. Domingo 

 (U. S. Tech. Ser. 20, part 3, 1911, p. 138). 



The genus Xylopertha should be expunged; the species sextuberculata 

 is Zylomeira torquata (Fabricius) ; the species minutus is cosmopolitan and 

 belongs in Dinoderus. 



Hetcrarthron gonagra (Fabricius). Jamaica, Dominica (U. S. N. M.). 



* Heterarthron plicatus (Leconte). Cuba, Jamaica (U. S. N. M.). 

 Rhizopertha pusilla (Fabricius). Porto Rico (A. M. N. H.). Cosmo- 

 politan species or introduced from the United States in timber. 



* Sinoxylon floridanum Horn. Antigua, Jamaica (U. S. N. M.). Cos- 

 mopolitan species or introduced from the United States in timber. 



Apate francisca Fabricius. Porto Rico (Van Zwaluwenburg) . 



* Apate terebrans (Pallas). Jamaica (reared from Anacardium occidentale) . 



Family XLVI. CIOID.E. 



Ennearthron delicatuluvi Jacquelin Duval. Porto Rico (Gundlach). 

 Strike out Ceratocis, transferring the species to Ceracis. 



Family XLVIII. PASSALID.E. 



Passalus tlascala Percheron is a Neleus. 



It is doubtful that Passalus unicornis (Serville) occurs in Cuba or 

 Guadeloupe. 



Passalus interruptus (Linne). Martinique (Marshall). 



Family XLIX. SCARABiEID^E. 



Chceridium insulare Chevrolat. Montserrat (U. S. N. M.). 



* Canthidium melanocephalum (Olivier). According to Olivier (Ent., 

 I, 3, pp. 173, 174,) the type of this species was described from Guadeloupe 

 but von Harold, in Coleopterologische Hefte, I, pp. 29-30, gives Brazil as 

 the locality for the species and more recent authors have followed the latter 

 record, excepting Fleutiaux and Salle, who very likely followed Olivier, as 

 they had no specimens of this species to verify the records.
