302 MEMOIRS ON THE COLEOPTERA 



stout, not annulated, the outer joints short and compactly joined. 

 [Type Acanthoderes funerarius Bates]. Mexico and Central America. 



*Pardalisla 



Prosternal and mesosternal processes differing from any of the preceding, 

 narrower, the latter very gently sloping, perfectly simple; elytra 

 elongate, very feebly cuneiform to subparallel, obliquely truncate 

 at apex, nearly smooth, punctured, each with or without two feeble 

 discal raised lines; antennae as in Acanthoderes but slender, annulate; 

 last dorsal segment of the abdomen ( 9 ) produced slightly at apex 

 as in the Acanthocinini, which is not the case in any of the preceding 

 genera. [Type L. decipiens Hald.]. Eastern America. 



JEgomorphus 



ACANTHODERES Serv. Limited so far as known to a few peculiar 

 species of the northern part of South America, as stated by Lacor- 

 daire (Gen. Col., IX, 2, p. 753). 



PARDALISIA n. gen. The type of this genus, as stated above, 

 is of isolated habitus in the present group, owing to the stout 

 parallel form of the body, short thick compact antennae, conjointly 

 rounded elytral apices and type of ornamentation. 



^EGOMORPHUS Hald. (Dej. Cat.) This is a very distinct genus, 

 forming a bond between the Acanthoderini and Acanthocinini; 

 so far as known to me, we have in the Atlantic regions of North 

 America, to which it is probably confined, but two species decipiens 

 Hald., and morrisi Uhler. As this genus is valid it will be neces- 

 sary to rename the genus JEgomorphus of Thomson (Essai, p. 336). 



Psapharochrus Thorns. 



Besides the described quadrigibbus Say, and cornutus Bates, 

 which I have before me, this genus will include many other similar 

 species from Mexico and Central and South America, among which 

 the two following appear to have been as yet unannounced: 



*Psapharochrus histrio n. sp. Form and ornamentation very much 

 as in quadrigibbus, the elytral punctures sparse and stronger, involved in 

 conspicuous black dots, which are absent in that species; body stout, 

 rather convex, black, the vestiture fine, close, very short and dense, 

 red-brown, variegated with some black maculation on the elytra, an 

 irregular oblique discal spot, a small one slightly posterior and near the 

 side and two small ones near the apex, on each, being evident; each 

 elytron also with an oblique ochreo-cinereous sinuous fascia from the 

 margin behind the humerus to about inner third, surrounded internally 

 by a blackish border; head dark brown, with scattered small perforate 

 punctures; antennal joints three and four each with two loose pale annuli, 

 the remainder each with a single subbasal to basal annulus; prothorax
