divergence between the specimens and the description is in 

 the punctation of the pygidium; the description states that the 

 pygidium is "sat dense" punctured; it is not as densely punc- 

 tured as the pygidium of yucateca, which Marseul says is 

 "densement et assez fortement ponctue. " If one had seen 

 yucateca, the term dense, even modified, would not be applied 

 to the punctation of the pygidium of princeps, as the punctures 

 are in many places separated by from two to four times their 

 own width.

Horn, Pro. Am. Phil. Soc, p. 274. 1873. 

 Broadly oblong. Front with two extremely slight depressions, 

 which may or may not have very lightly impressed striae at their bot- 

 toms; preocular tooth slightly prominent, depressed, supraorbital stria 

 long, distinct. Mandibles longer than the head (d^) or equal in length 

 to the head ( 9 ), stout, usually with a short stria on the upper surface, 

 near the external margin and base.' Pronotum bi sinuate at base, with a 

 median, longitudinal stria, more or less lightly impressed, extending 

 from the base past the iniddlc; marginal stria entire, rounding the 

 posterior angle, and terminating in a more or less deep fossa close to 

 and behind the anterior angle, rather sharply broadened anterior to 

 the middle ( cf ) or gradually slightly broadened ( 9 ) ; two short striae 

 near the anterior margin behind the eyes. Elytra bistriate, the outer 

 strong, deeply impressed, usually about one-third the length of the 

 elytra, second shorter, usually with an apical appendix of varying 

 length; subhumeral stria abbreviated at base, slightly abbreviated at 

 apex. Inflexcd portion of elytra rugose. Propygidium with disk smooth, 

 laterally punctate with a band of moderately coarse punctures which are 

 coarsest near the base; apex very finely punctate. Pygidium densely 

 and coarsely punctate, punctures separated usually by less than their 

 own diameter. Mentum slightly concave, punctate. Presternum 

 truncate at apex, elevated, punctulate. Ventral segments of abdomen 

 punctate at sides only. Lower crest of fore and hind tibiae not dentate. 

 Length 8-10 mm. 



Distribution. Southern California, New Mexico, Arizona 

 and Texas. 



Variants. This species may have the second stria entire, 

 more or less widely interrupted, or with the apical appendix 

 reduced to a very faint line, a series of shallow punctures, or 

 entirely lacking.
