[Rololepta fossularis, Say] ; mandibles rather strongly curved 

 and shorter [?than in L. yucateca]." 



L. 171 mill. 



Lioderma yucateca, Mars., and L. grande, Mars., are the 

 sexes o£ one species ; Hololepta fossularis, Say, has a wide 

 prosternal keel, Lioderma grande. Mars., a narrow one. 



" Hololepta neglecta, sp. n. 



" Narrower and more elongate than vicina \_Hololepta, Lee, 

 but a Lioderma]. Mentura feebly concave, lines [? dorsal 

 strise] rudimentary ; prosternum slightly narrowed, sub- 

 truncate, sides of prothorax quite evenly arcuate. Side of 

 the body moderately arcuate. 



'' L. 7 mill. 



" This species was identified for me as H. lucida, but is 

 entirely different in habitat from specimens subsequently 

 obtained of that species. ^^

Ovatus, subconvexus, niger, nitidus ; fronte transversim. punctata, 

 stria bisinuata ; pronoto lateribus punctato ; elytris striis 1 

 Integra, 2 basi abbreviata ; propygidio ufcrinque grosse in medio 

 minor punctato ; prosterno bistriato, lobo grosse punctato. 



L. 13-14 mill. 



Oval, somewhat convex ; the head, frontal stria bisinuous, 

 with irregular punctures along its posterior edge, in tlie 

 middle the punctures are formed to represent the acumination 

 seen in P. piidicus, Mars. ; the thorax, the marginal stria is 

 complete, the lateral strong and feebly sinuous near the 

 middle and along its border are irregular punctures ; the 

 elytra, striae, outer humeral nearly complete but broken 

 before the apex, inner apical reaching just beyond the middle, 

 1 dorsal complete, 2 a little shortened at the base, 3 evan- 

 escent ; the propygidium is not very closely punctured and 

 the points are relatively small as compared with the other 

 known species, especially in the median area ; the punctures 

 on the pygidium are larger and more close ; the prosternum, 

 the anterior lobe is coarsely punctured, the keel has two 

 sinuous striaj which are punctured along the inner edges ; the 

 mesosternum is not margined anteriorly ; the hind tibiae are 

 widely emarginate on the outer edge before the tarsal end. 

 Separated from the other species by the punctuation of the 

 thorax.
