130 MB. D. SHARP ON SOME NEW SPECIES OP 



figure certainly represents a female individual, and, I think, 

 very probably a species distinct from Burmeister's P. ohesa. 

 Of each of the two species I here describe, I have seen but a 

 single individual, one of which is male, the other female, the 

 sexual disparities being remarkable : had these two individuals 

 been found together, or in the same district, I should have con- 

 sidered it probable that they were the sexes of one and the same 

 species ; but as this was not the case, I have thought it better to 

 consider them at present as two distinct species. It would appear 

 probable, then, that Pliatangogoiiia obesa, Burm., is a Mexican spe- 

 cies, of which the female only is described, that P. obesa, Lacor- 

 daire (Z. c), is a representation of a female of an allied Mexican 

 species, while P. sperata, Sharp, is a Central-American species 

 described from a single male individual, and P. stipes, Sharp, is 

 possibly only a female variety thereof. 



Among the more interesting species represented in Mr. Belt's 

 collection are : — Megathopa candezei, of which an admirable 

 diagnosis has been recently given by Baron von Harold, but 

 which, I think, would have been better treated as a distinct 

 new genus, between JSIegatliopa and Canthon ; a beautiful 

 Phisiotis, which M. Boucard calls a variety of P. aurora ; a 

 form allied to Felidnota, and another to Chlorota, both perhaps 

 really new genera, but represented only by single individuals ; 

 Podischmis terisander, Burm., which I have never seen before, but 

 which undoubtedly is a distinct species from the common P. 

 agenor ; the very remarkable Amblyodon nicaragucs, "Westwood, 

 which is the male of Phileurus nasicornis, Burm., or at any rate 

 a closely allied species ; a pair of the very rare Lycomedes reichei ; 

 a sei'ies of AUorJiina anomala, Bates, showing that the species 

 varies in size from 19 to 26 millims., and greatly in the develop- 

 ment of the pale markings, the thorax being in one individual 

 entirely bordered with a pale yellow marking ; a series of Ggm- 

 netis ramulosa, Bates, in which the transverse pale mark of the 

 elytra is alike in no two individuals, and shows also a sexual dis- 

 parity ; and a pair of the elegant Dialitlius magnificus, in one in- 

 dividual the elytra being black, while in the other they are red. 

 Onthophagus tapirus, n. sp. Thorace in utroque sexu mutico. 

 Subdepressus, nigro-seneiis, nitidus, capite et thorace magis aeneis, 

 pedibus piceis ; thorace spai'sini, minus fortiter punctato, elyti-is evi- 

 denter striatis, interstitiis impunctatis ; pygidio fortiter punctate. 

 Long 6^-7 miilim.
