[llololepta fossuIariSf Say] ; mandibles rather strongly curved 

 and shorter [?than in L. i/ucateca'\." 



L. 17i mill. 



Lioderma t/ucateca, Mars., and L. grande, Mars., are the 

 sexes of one species ; Hololepta fossularis. Say, has a wide 

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



" Hololepta neglecta, sp. n. 



" Narrower and more elongate than vicina [^Hololepta, Lee, 

 but a Lioderma']. Mentum 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 //. liicida, 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 

 iutegra, 2 basi abbreviata ; propygidio utriiique grosse in medio 

 minor punctato ; prost«rno bistriato, lobo grosse punctato. 



L. 13-14 miU. 



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

 with irregular punctures along its posterior edge, in the 

 middle the punctures are formed to represent the acumination 

 seen in P. jmdicus, 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, strise, 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 striae 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.
