the Coleopterous family Passalidm. 451 



the types of P. sjnnipes, Zang, of which we have 

 specimens from Chulumani, Bolivia, and R, Marca- 

 pata, Peru. The Peruvian specimen is 47 mm. long. 

 The spines upon the four posterior tibige, from which the 

 species is named, are not always easily distinguishable, 

 but it is a very well-marked form, easily recognisable by 

 the feebleness of the elytral strife, which, contrary to the 

 almost invariable rule among these insects, become fainter 

 instead of stronger towards the sides. 



Kuwert has formed a new genus Vcrroides for certain 

 insects inhabiting Brazil and Guiana, of which he has 

 recognized three species, differing from Vcrres only in the 

 labrum being very deeply cleft. I believe one or all of 

 them to be Vcrres ftircilahris, Eschs., which Kuwert has 

 left in the older genus. This is evidently due to some 

 blunder, as he gives the habitat as Guatemala, although 

 each of the authors quoted by him without comment has 

 recognised it as a South American species. There are 

 specimens in our collection, all of which I regard as belong- 

 ing to Vcrroides furcilcihris, Eschs., from the Amazons 

 (Monte Alegre and Para), Pernambuco, British Guiana 

 (Georgetown) and Trinidad. 



In the succeeding pages I describe, in addition to a 

 new genus which I have already referred to as necessary 

 for Passal'us occiintalis, Eschs., a few well-marked new 

 forms in our collection, beoinnino- wdth one from the 

 island of Grenada. In order to complete the enumeration 

 of the Lamellicorn Coleoptera of St. Vincent and Grenada 

 contained in two previous papers in these Transactions I 

 give here a list of all the Passalidse from the West Indian 

 Islands contained in our collection : — 



Vcrroides fur cilabris, Eschs., Trinidad. 



Spasahis puncticollis, Serv. (Kuw.), Dominica, St. Lucia, 



Nevis. 

 Passalus {Nelcus, olim) interriiptus, L., Trinidad. 

 P. unicornis, Serv., Dominica, St. Lucia. 

 P. tlascala, Perch., Trinidad, Grenada, St. Vincent. 

 Scalmus {Ninus, Kuwert), inter stitialis, Eschs., Trinidad, 



Grenada, Cuba, Jamaica. I can find no adequate 



justification for the numerous so-called species into 



which Kuwert has divided this. 

 Pertinacides affi.nis, Perch., S. Domingo, Hayti. 

 JVeleides antillarum, sp. n., Grenada.
